Page 35 Feature Reference Star Codes and Allowed/Disallowed Lists In some instances, after dialing a star code (a star digit followed by a two or three digit number) the central office provides a second dial tone as a prompt for the dialer to enter more digits. In most cases this second dial tone is immediate.
Page 36 Feature Reference Following are examples of specific results that cannot be achieved through programming MERLIN LEGEND: Disallow *67 when dialing a specific exchange. Disallow *67 only when it is followed by *69. Default Disallowed List In Release 3.1 and later, a default Disallowed List (list 7) is defined which includes the following entries: , , ppp ( p =any digit).
Page 37 Feature Reference If a zero (0) is programmed as the first digit of an Allowed List entry, any toll restriction assigned to an extension is removed for calls placed through a toll operator. Individual Allowed and Disallowed Lists are numbered 0 through 7. Within each list, there are 10 entries numbered 0 through 9.
Page 38 Feature Reference Conference A user with a restricted extension cannot add a participant (outside or toll) to a conference call unless the participant’s number is on the Allowed List for that extension.

Page 56 Feature Reference Ringing/Idle Line Preference Ringing/Idle Line Preference is a single option that controls two aspects of a telephone’s behavior: selection of a line when a call arrives, and selection of a line when a user goes off hook. Turn this option on or off for each extension through extension programming or centralized telephone programming, using the display or programming codes.
Page 57: Table Of Contents
Feature Reference Up to eight line buttons (except on single-line telephones) can be programmed in the ALS sequence for an extension, either through centralized telephone programming or through extension programming, using programming codes only. IMPORTANT: Your current Automatic Line Selection table is deleted immediately after you press .
Page 58 Feature Reference Considerations and Constraints Outside line buttons and SA or ICOM buttons can be included in the ALS sequence. However, inside and outside lines should not be interleaved. A typical sequence would consist of all desired SA or ICOM buttons, followed by all desired outside line buttons.
Page 59: Single-Line 3. Sa O
Feature Reference Behind Switch Mode The factory-set ALS sequence includes only the prime line. The sequence can be changed to an ICOM line followed by the prime line or outside lines. This allows the single-line telephone user to use system features and to select the prime line and/or outside lines by dialing the Idle Line Access code (usually Telephone Differences Queued Call Consoles...

Coverage When Ringing/Idle Line Preference is on for an extension, the system automatically selects a Primary Cover, Secondary Cover, or Group Cover button with a ringing call.
Page 61: Automatic Maintenance Busy
Feature Reference Automatic Maintenance Busy At a Glance Users Affected Telephone users, operators Reports Affected System Information Mode Hybrid/PBX System Programming Description When Automatic Maintenance Busy is enabled, a malfunctioning loop-start, ground-start, or tie trunk is automatically put in a maintenance-busy state, preventing outside calls from being made on that trunk.
Page 62 Feature Reference Considerations and Constraints Incoming calls are received and processed normally on trunks in a maintenance-busy state. Direct Inward Dialing (DID) trunks (Hybrid/PBX mode only) are not affected by Automatic Maintenance Busy, because these trunks can only receive calls and are not pooled.

Page 65 Feature Reference Description Automatic Route Selection (ARS) is available only in Hybrid/PBX mode. ARS allows outgoing calls to be dynamically routed over selected trunk facilities after dialing an ARS access code (usually a ). This enables the system to select the least expensive route for each call.
Page 66 Feature Reference Absorbed Digits. The number (0 to 11) of user-dialed digits that ARS absorbs (does not dial out) on this route. Digits are absorbed starting with the first user-dialed digit after any leading star codes. System-Prefixed Digits. A string of up to 20 digits (0–9, *, and Pause) that ARS dials out on this route before dialing any remaining user-dialed digits but after dialing any user-dialed leading star codes.
Page 67 Feature Reference Default Toll Table. This factory-set table routes toll calls to numbers that do not match entries in any of the area code, 6-digit, or 1 + 7 digits. This table has two subpatterns of up to six routes each, but neither absorbed digits nor system-prefixed digits are used.
Page 68 Feature Reference Star Codes and Automatic Route Selection In some instances, after dialing a star code (a star digit followed by a two or three digit number) the central office provides a second dial tone as a prompt for the dialer to enter more digits. In most cases this second dial tone is immediate.
Page 69: Feature Reference
Feature Reference How ARS Works A user with inside dial tone on an SA button dials the ARS Access Code (usually ) and is connected to ARS. Then the user dials a call. If the telephone is restricted or toll-restricted and the number dialed is not on the Allowed List, or if the number dialed is on the Disallowed List, the user receives a system error tone.
Page 70 Feature Reference First Digit a 1 (Not an Equal Access Code) In this case, ARS eliminates the Default Local, Dial 0, Special Number, and Local Exchange Tables. ARS proceeds as described below. AAAA AAAA AAAA AAAA AAAA AAAA AAAA AAAA AAAA AA AA AAAA...

Page 72 Feature Reference Route Selection within the Table Once the table is selected, ARS checks the subpatterns within the table (if applicable) and the restrictions on the routes. START Selected Table If appropriate for the selected table, select Subpattern A or B depending on time of day.
Page 73 Feature Reference Subpattern B Is Call Time after Dial Call Subpattern B start and and Select Table before Subpattern B Stop Subpattern A Figure 3. Subpattern Selection Restrictions If the extension’s Facility Restriction Level (FRL) is equal to or greater than the FRL of any of the routes in the selected subpattern, those routes are eligible for selection.
Page 74 Feature Reference NOTE: If a voice call is queued for callback on a digital trunk pool, it can get stuck in an infinite loop of queuing. The caller hears a continuous stutter tone and cannot get rid of it. To avoid this situation, be certain to correctly program the voice and/or data capabilities of pools of PRI and BRI facilities in the ARS tables.
Page 75 Feature Reference Some central offices still require the prefix 1 for dialing certain exchanges. If 1 + 7-Digit Dialing Requirements option is programmed as Within Area Code, the system expects either dial timeout or a (end of dialing) to indicate whether a 1 + 7-digit or a 1 + 10-digit number has been dialed.
Page 76 Feature Reference Calling Restrictions The use of ARS does not allow callers to avoid calling restrictions. The system checks for outward or toll restrictions assigned to the extension or barrier code before it selects the best route for making the call. ARS and dial access to pools function independently from each other.
Page 77 Feature Reference Saved Number Dial The ARS dial-out code is saved with the telephone number dialed. SMDR SMDR reports for systems with ARS show all the digits dialed by the user in the CALLED NUMBER field, including any absorbed (ignored) digits, and the facility used to make the call.
Page 78 Feature Reference Barge-In At a Glance Users Affected Telephone users, operators Reports Affected Extension Information Mode Telephones All except single-line telephones Programming Code (centralized telephone programming only) QCC Display Label Description Barge-In allows a caller to contact a co-worker in an emergency or when the caller has been given special instructions to interrupt.
Page 79: Direct-Line Consoles
Feature Reference Telephone Differences Direct-Line Consoles If the DLC operator uses Barge-In to reach someone with Coverage or Forwarding (including Remote Call Forwarding) on, the call from the operator is not directed to the destination (receiver’s) extension. The call is directed to the extension on which Barge-In is used.
Page 80 Feature Reference Display Barge-In appears on the display as a feature choice only on QCC operator consoles. On an MLX display telephone receiving a Barge-In call, the message and either the name or extension number of the person joining the call remains on the display until the receiving telephone user hangs up.

Page 82 Feature Reference Description Basic Rate Interface (BRI), like Primary Rate Interface (PRI), is a standard protocol for accessing Integrated Services Digital Network (ISDN) services. By using BRI, the MERLIN LEGEND Communications System can connect with the speed and accuracy of ISDN services. National ISDN-1 (NI-1) BRI service is available for MERLIN LEGEND Communications Systems Release 4.0 and later only.
Page 83: Line
Feature Reference Terminology Lines/Trunks In this section on BRI, lines are the representations that appear on extension sets or are put into pools. Trunks are the facilities that link switches. For all trunks except DS1 (T1 or PRI) and BRI, internal line numbers have a one-to-one correspondence to trunk ports.
Page 84 Feature Reference NOTE: Multiline Hunt is not part of the IOC package S. If Multiline Hunt is needed, you need to order the appropriate feature and inform the central office of the switch settings in Appendix H of System Planning that you need. Digital Subscriber Line (DSL) A Digital Subscriber Line provides full-duplex service on a single twisted pair wire (two-wire) at a rate sufficient to support ISDN Basic Rate Access.
Page 85 Feature Reference Service Profile Identifier A Service Profile Identifier (SPID) is a unique identifier used by the central office to associate an ISDN terminal with a Service Profile. It is provided to the user by the central office at subscription time. The system manager must program the SPID for each BRI line to bring the BRI line into service (activate).
Page 86 Feature Reference The following lists the options for primary, secondary, and tertiary clock synchronization sources in order of preference: 1. The clock sources on BRI ports with DSLs in service. If at all possible, all three clock sources should be on the same 800 NI-BRI module. 2.
Page 87: Call
Feature Reference T303 Timer. Times the delay in network response when the communications system sends a setup message to initiate an outgoing call. T305 Timer. Times the delay in network response when the communications system sends a disconnect message to clear a call. T308 Timer.
Page 88 Feature Reference Call Processing An explanation of incoming and outgoing call processing follows. Incoming Calls BRI calls can be received on Personal Line or Pool buttons, or by Calling Groups or the QCC Queue. Incoming calls appear to the user like those on other types of lines.
Page 89 Feature Reference Pool Button. Like any other type of line/trunk, a BRI line can be accessed by using a Pool button or by using an SA button and dialing a pool access code. Automatic Route Selection. Like any other type of line/trunk, a BRI line can be accessed by using an SA button and dialing the Automatic Route Selection (ARS) access code.
Page 90 Feature Reference Call Waiting Call Waiting is provided on BRI lines at extensions so programmed. The call-waiting tone is not blocked from BRI at an extension if turned on. Conference Calls on BRI lines can be part of a conference call processed by the MERLIN LEGEND system, not by the central office (CO).
Page 91: Call Waiting
Feature Reference Call Waiting At a Glance Users Affected Telephone users, DLC operators Reports Affected Extension Information Mode Telephones All except QCC Programming Codes Feature Code (for call-waiting pickup) MLX Display Label Factory Setting Description When an extension is programmed with Call Waiting, a user hears a tone when his or her extension is busy, the user is off hook, and another call is received.
Page 92 Feature Reference The user hears a call-waiting tone for the following types of calls that ring on an SA or ICOM button: An inside call A call received on a Direct Inward Dial (DID) trunk A call from a remote access user A call received on an automatic dial-in tie trunk A call transferred to the extension The user does not hear a call-waiting tone for calls received on a personal line...
Page 93 Feature Reference Telephone Differences Queued Call Consoles Call Waiting cannot be used on Queued Call Consoles (QCCs); the calls are already queued. Release a call to a busy extension by selecting Camp-On from the display or by pressing the Release button. If Camp-On is used, the call does not return to the QCC queue until the Camp-On return interval expires.
Page 94 Feature Reference Callback (continued) When Selective Callback is used to queue a call at an extension that has Call Waiting, the user with call waiting hears the call-waiting tone and the call is queued until the extension becomes available. Camp-On A user with no available buttons to receive a transferred call hears the call-waiting tone when a co-worker uses Camp-On to transfer a call, even if Call Waiting is not activated.
Page 95 Feature Reference System Access/ An extension is considered busy when all SA or ICOM buttons Intercom Buttons (excluding SA Originate Only or ICOM Originate Only) are in use. A multiline telephone user can dial the Call Waiting feature code to pick up a waiting call only when an SA Originate Only, or ICOM Originate Only button is available.

Page 97 Feature Reference Two types of Callback can be programmed for an extension: Automatic. Callback is activated automatically whenever the caller reaches a busy extension or when all trunks in a pool are busy. This is a status feature that is set to On or Off for each extension. Selective.
Page 98 Feature Reference When a call is waiting in queue for an extension, no new calls are sent to the extension until after the queued call is completed. When the queue contains 64 calls (system limit), additional calls sent to the queue result in a busy signal.
Page 99 Feature Reference Single-Line Telephones A single-line telephone user can make and receive other calls while waiting for the call to be completed. The request remains in the queue until the user who initiated the request is available. Queued calls ring at a single-line telephone in the order which they were queued.
Page 100 Feature Reference Conference With Automatic Callback, the call is automatically queued; however, if a person tries to add the queued call to the conference, the system returns a busy tone. With Selective Callback, the system also returns a busy tone. To drop the busy tone from the conference, the originator presses the Drop button and then the line button used to call the busy extension.
Page 101 Feature Reference Forward and If a forwarding extension is busy when a user calls, the user can queue Follow Me the call for callback. Callback is completed when the forwarding (continued) extension is no longer busy. If the forwarding extension and the forwarded-to extension are available, the call rings at both extensions.
Page 102 Feature Reference Paging Callback cannot be used for calls to a speakerphone paging group. A voice-announced inside call that is queued using Callback automatically becomes a ringing call. Systems with Loudspeaker Paging can be set up to allow calls to be queued for the Loudspeaker Paging system by placing the Loudspeaker Paging jack in its own pool and having users access the paging system through the pool.

Page 105 Feature Reference Display Operation Caller ID information is displayed on MLX display telephones only. The display shows when the call is answered before the Caller ID data arrives, when the Caller ID data is corrupted, or when no Caller ID data is sent from the central office.
Page 106 Feature Reference Considerations and Constraints General A user must subscribe to the Caller ID service in order for incoming calls through the 800 GS/LS-ID port module to receive Caller ID information (loop-start lines only). Caller ID/PRI ANI Comparison Caller ID information arrives between the first and second ring at an extension.

Page 150 Feature Reference Cover to Voice Mail with Escape to System Operator When DID or Auto Attendant are used, users receive calls directly, without the intervention of an operator. In these situations, the telephone should have voice mail coverage instead of coverage by a receptionist (operator). The caller then has the option to leave a message or press in order to talk to the receptionist.
Page 151 Feature Reference Primary Coverage If eight or fewer extensions require coverage to the system operator, use delayed Primary Coverage or Secondary Coverage to allow calls to be covered by the operator. When a caller dials the user’s number, the call is covered by the operator, and the operator can then send the call to voice mail using the Direct Voice Mail feature.
Page 152 Feature Reference With the primary coverage configuration, calls are handled as follows. A caller dials a DID number (for example 555-5512). The extension for the DID number (for example, extension 12) rings several times. If the telephone is not answered, the call is covered by an operator. If the operator fails to answer, the call goes either to voice mail or keeps ringing, depending on the Coverage VMS Off status on the extension for the DID number.

Page 155 Feature Reference Cover to Personal Secretary before Voice Mail If you need coverage by a personal secretary, who is not a system operator at an operator console, then Primary Coverage can be used on the secretary’s telephone. The secretary can use Direct Voice Mail to transfer the call back to the user’s voice mail.
Page 156 Feature Reference Considerations and Constraints In Release 2.0 and later, if a receiver calls a sender for whom he or she is covering and the sender is busy or unavailable, the call proceeds to other points of coverage. It does not come back to the receiver who originated the call.
Page 157 Feature Reference When both the QCC queue and multiline telephones are programmed as receivers for a coverage group, the QCC queue is not counted in the 8-receiver maximum for the group. A QCC cannot be a coverage sender. When Group Coverage is the only type of coverage programmed for a sender, the QCC queue should not be programmed along with Group Cover buttons on multiline telephones.
Page 158 Feature Reference Queued Call Consoles The Queued Call Console (QCC) cannot be a sender for either Individual or Group Coverage. The QCC queue can be a Group Coverage receiver for up to 30 coverage groups. Since Cover buttons cannot be programmed on the QCC, the queue is not counted in the 8-receiver maximum allowed for each coverage group.
Page 159 Feature Reference Transferred calls to a busy single-line telephone are not eligible for coverage unless Coverage Inside is on. A transferred call to a busy single-line telephone with Group Coverage and Coverage Inside off camps on at the single-line telephone and returns to the originator if not answered before the transfer return interval expires.
Page 160 Feature Reference Call Waiting A call to a sender with Call Waiting turned on goes to Individual and/or Group Coverage first. If all coverage points are busy, the sender receives the call-waiting tone. Camp-On Coverage calls answered by any receiver can be camped-on to another user.

Page 234 Feature Reference Considerations and Constraints Do Not Disturb must be programmed onto an available button. If you turn on Do Not Disturb while receiving a call (either ringing or voice-announced), the caller continues to hear ringback (or a voice-announced caller may stay on the line), but you do not hear ringing. The Do Not Disturb feature remains on.
Page 235 Feature Reference Feature Interactions Auto Dial When you turn on Do Not Disturb, the green LEDs next to all Auto Dial buttons programmed with your extension go on. Barge-In Barge-In overrides Do Not Disturb. Callback Calls to a user with Do Not Disturb turned on are not eligible for callback queuing.

Page 244 Feature Reference In addition to the above, the Fax Extension feature also provides the ability to notify certain extensions when a fax is received by turning on the Message LED (Fax Message-Waiting Extension). The fax message threshold setting is the length of time (0–30 seconds) before the system assumes that a fax has arrived.
Page 245 Feature Reference Considerations and Constraints A fax extension can send the message-waiting indication, but a fax extension cannot be assigned as a message-waiting receiver for another fax or for a calling group. If a fax message-waiting indication is deleted by one of the four message-waiting receivers, the message is deleted from all of the telephones programmed as message-waiting receivers for the fax.

Page 247 Feature Reference At a Glance (continued) Maximums Forward-to destinations for each sending extension Unlimited Forward-from extensions for each receiving extension Factory Setting Remote Call Forward Not allowed Forwarding Delay 0 rings (0-9 rings) Description Forward and Follow Me provide two ways for a user to send calls to another number.
Page 248 Feature Reference All users except Queued Call Console (QCC) operators can use Forward or Follow Me to forward calls to another extension. Calls cannot be forwarded to a calling group. The factory setting for Remote Call Forward is that users are not allowed to forward calls to outside numbers.
Page 249 Feature Reference If the personal line is a loop-start trunk, it must provide a reliable disconnect signal. A disconnect signal is the signal sent by the local telephone company to notify the system that an outside caller has hung up. Disconnect signaling is considered reliable when a disconnect signal is sent on every call when the caller hangs up, and is considered unreliable when a disconnect signal is not sent on every call.
Page 250 Feature Reference Do Not Disturb overrides the Delayed Call Forwarding. Calls are immediately forwarded if Do Not Disturb is on while Forward or Follow Me is active. Considerations and Constraints On multiline telephones, Forward should be programmed on a button so that the LEDs provide a visual reminder when calls are being forwarded.
Page 251 Feature Reference No error tone sounds when a user with a restricted telephone uses Remote Call Forward. However, when a call eligible for forwarding is received, the system checks restrictions and denies the forward if the outside telephone number is not on an Allowed List assigned to the restricted extension or is included on a Disallowed List assigned to the restricted extension.
Page 252: Call
Feature Reference The reasons that a call may ring for more than the programmed Delayed Call Forwarding setting are the following: If a button is programmed as Delayed Ring, the Forwarding Delay begins after the Delayed Ring period ends. The two delays are cumulative. The destination for the Forwarded call may not be available to receive the call.
Page 253 Feature Reference To cancel Forward and Follow Me from other extensions: at the destination QCC, press the Feature button, select (Cancel Follow Me) from the display, and do one of the following: To cancel forwarding from one extension, dial that extension number. To cancel forwarding from all extensions, dial Other Multiline Telephones To forward calls to an extension, either press a programmed Forward button...
Page 254 Feature Reference If off hook on an SA or ICOM button, you hear confirmation tone, and then dial tone is removed. Single-Line Telephones At a single-line telephone, turn on forwarding to an extension by lifting the handset, which must connect to an SA or ICOM line, and dialing and the destination extension number.
Page 255 Feature Reference Allowed Lists and A user with an outward- or toll-restricted telephone cannot forward calls Calling Restrictions to an outside number unless the number is on an Allowed List assigned to the restricted extension. No error tone sounds when a user with a restricted telephone uses Remote Call Forward.
Page 256: Coverage
Feature Reference Caller ID The systemwide LS-ID delay, if programmed, is in addition to the Forwarding Delay. The total delay is the LS-ID delay plus the Forwarding Delay. Call Waiting Call Waiting does not apply to forwarded calls, because the system tries the destination telephone instead of the forwarding telephone.
Page 257 Feature Reference Direct Station Forward can be turned on by pressing a programmed Forward button Selector or using the feature code, then pressing a DSS button corresponding to the destination extension. Follow Me can be turned on by using the feature code and pressing a DSS button corresponding to the forwarding extension.
Page 258 Feature Reference Display When an MLX display telephone user turns Follow Me on or off, the continued display prompts for the forwarding extension. After the feature is turned on, the message appears. After the feature is turned off, appears. If an MLX display telephone user enters an invalid destination while turning on Forward, the display clears.
Page 259 Feature Reference Park Returning parked calls are not forwarded. Personal Lines When an extension is programmed as the principal user of a personal line, calls arriving on the personal line can be forwarded to an outside number (if the extension can use Remote Call Forward), unless the personal line is a loop-start trunk with unreliable disconnect.
Page 260 Feature Reference System A Shared SA button cannot be used to turn on Forward or Remote Call Access/Intercom Forward for the principal’s telephone. Calls received on a Shared SA Buttons button are not forwarded. When calls are forwarded to an extension, a call received on an SA or ICOM button rings once at the forwarding extension’s SA or ICOM button (including all assigned Shared SA buttons, even though a call received on these buttons is not forwarded) and rings at the destination...

Page 264 Feature Reference Individual calling group member extensions are assigned an extension number, allowing a group member to receive calls as an individual and as a group member. Calls that come into a calling group are usually not intended for a particular group member and can be handled by any member.
Page 265 Feature Reference Do Not Disturb is off. Calls are not being forwarded through Forward, Remote Call Forward, or Follow Me. The calling group member has not activated Callback to reach a busy trunk (Hybrid/PBX mode only) or extension. The calling group member is not about to receive a call from another extension who has used Callback to reach the member.
Page 266 Feature Reference The order in which the system searches for an available calling group member for subsequent calls can be either circular or linear and is called the hunt type . The two hunt types are as follows: Circular. As subsequent calls arrive, the system searches for an available calling group member, starting with the extension after the last extension to receive a call.
Page 267 Feature Reference Each announcement device has an extension number. Therefore, a calling group member or calling group supervisor can dial this number to check or change the announcement as long as the delay announcement device allows the user to read or change messages remotely. If the device is malfunctioning and does not answer the call within 30 seconds (five rings), the system automatically logs out the device and makes it unavailable for subsequent calls until the calling group supervisor logs in the...
Page 268 Feature Reference Calls-In-Queue Alarm Threshold The Calls-In Queue Alarm Threshold is the number of calls (1–99) allowed in the queue before calling members are notified. When the number of waiting calls is equal to or greater than the programmed Calls-In Queue Alarm Threshold (factory setting is one call), the calling group members can be notified in one of two ways: Through an external alert connected to an MLX telephone by using a...
Page 269 Feature Reference Overflow Threshold Time In Release 4.0 systems, there is also an Overflow Threshold Time setting. The Overflow Threshold Time is the maximum time that any call can remain in the calling group queue before it is sent to the Overflow Receiver. If the Overflow Threshold Time is set to 0 seconds (factory setting), then Overflow by time is off.
Page 270 Feature Reference QCC Queue Overflow Receiver When the QCC queue is assigned to provide overflow coverage for a calling group, the following conditions must be met before calls are directed to the QCC queue: The number of calls in the calling group queue must be equal to or greater than the programmed overflow threshold.
Page 271 Feature Reference Extension Status must be set to calling group/Call Management System (CMS), the factory setting, and not hotel configuration.

Page 272 Feature Reference In Release 2.1 and later, an 012 port that is programmed as a generic VMI port can transfer an outside call to an outside number (trunk-to-trunk transfer). Release 2.0 and earlier can only perform a trunk-to-trunk transfer on ports programmed as integrated VMI.
Page 273 Feature Reference To activate Extension Status, press the Feature button, dial , and press the Hold button. To return to normal call handling, press the Feature button, dial and press the Drop button. To change the availability of a calling group member, the supervisor activates Extension Status (if not already active), and presses a programmed button for Available (ES2) or Unavailable (ES0) and the Auto Dial or DSS button for the group member’s extension number.
Page 274 Feature Reference Feature Interactions Auto Answer All A calling group member with an analog multiline telephone can use Auto Answer All when an answering machine is connected to the extension. When the feature is activated, all incoming calls ringing on the group member’s telephone (both calls for the calling group and calls to the group member’s own extension) are answered automatically by the answering machine.
Page 275 Feature Reference Camp-On Users can transfer calls to a calling group by using Camp-On, but calls do not return to the originating extension, even if it is not answered within the programmed camp-on interval. If the calling group is made up of fax machines, a call-waiting tone is not given to the fax jack when the call is camped-on.
Page 276 Feature Reference Display Calling group agents with MLX display telephones see feedback messages on the display when they log into the Available state. When a calling group supervisor with an MLX display telephone logs calling group members in or out, a message appears on the supervisor display and on the group member’s display.
Page 277 Feature Reference Messaging Users can leave messages for the calling group only if the system has been programmed with a designated calling group message-waiting receiver. The receiver also receives fax message-waiting indications directed to the calling group. The message-waiting receiver cannot distinguish between messages left for the calling group and fax or personal messages.
Page 278 Feature Reference Ringing Options Abbreviated Ring is not operable for calls to the calling group extension because a calling group member active on a call is considered unavailable for incoming calls. In Hybrid/PBX mode, calling group members should program SA buttons for Immediate Ring. Signaling A Signaling button cannot be programmed for a calling group.

Page 282 Feature Reference Two things are necessary for an MLX telephone user or MLX DLC operator to use the Headset Auto Answer feature: A Headset Hang Up button must be programmed, as described earlier in this section. A Headset Auto Answer button must be programmed on the telephone or console, either through extension programming or through centralized telephone programming.
Page 283 Feature Reference Headset options cannot be used on analog multiline telephones or on single-line telephones. A headset user must manually select a line button or Call button (on the QCC) before making an inside or outside call. A user can press the Speaker button to move the call from the headset to the speakerphone.

Page 375 Feature Reference The system automatically reserves extension numbers 793–798 for the first six speakerphone paging groups. Up to 10 extensions can be assigned to each speakerphone paging group. The seventh speakerphone paging group is called the Page All group and is factory-set to page all extension numbers. The system automatically reserves extension number 799 for the Page All group.
Page 376 Feature Reference Considerations and Constraints A telephone without a speakerphone, loudspeaker, or speakerphone adjunct cannot be a member of a speakerphone paging group. After using Loudspeaker Paging, users must be sure to disconnect the paging call. Otherwise, the loudspeaker paging system may not be available by someone else.
Page 377 Feature Reference The system supports loudspeaker systems with talkback (bidirectional paging), which allows users to respond to pages. Prior to Release 2.1, users at extensions programmed with Forced Account Code Entry need to enter an account code to use Loudspeaker Paging. In Release 2.1 and later, users at extensions programmed with Forced Account Code Entry do not need to enter an account code to use Loudspeaker Paging.
Page 378 Feature Reference All Other Multiline Telephones To receive pages, analog multiline telephones must have Voice Announce to Busy on, and MLX telephones must have Voice Announce on; these are the factory settings. For analog multiline telephones, turning on the feature also requires assigning two consecutive jacks to the telephone: one for normal calls and another for pages.

Page 388 Feature Reference An extension can be programmed as the principal user (owner) of a personal line. When this is programmed, only the principal owner can forward calls to an outside number by using remote call forwarding. When the owner has Individual or Group Coverage, calls received on the personal line follow the owner’s coverage and not the coverage of telephones that also share the personal line.
Page 389 Feature Reference In Key mode, the factory setting for personal lines assigns the first 1–8 lines connected to the system as personal lines on all multiline telephones, including Multi-Function Modules (MFMs) connected to MLX telephones. In Behind Switch mode, the factory setting assigns personal lines to DLC positions rather than to multiline telephones.
Page 390 Feature Reference Call Waiting A user does not hear a call-waiting tone for calls received on a personal line unless the business subscribes to call-waiting service from the local telephone company. Coverage Assigning a sender as the principal user of a personal line specifies that the calls received on the personal line are sent to the principal user’s individual and group receivers.
Page 391 Feature Reference Digital Data Calls Personal lines can be assigned to terminal adapters and desktop video systems, however the personal lines should not be shared between them. Personal lines can be shared between an MLX and a terminal adapter connected to the MLX adjunct port. This configuration allows voice calls to ring at the MLX telephone, and data calls to be received by the terminal adapter.

Terminology Called Party Number (CdPN) In general, the term Called Party Number (CdPN) is a telephone number that was dialed to reach a destination. However, while routing the call, the network can change the Called Party Number to make routing easier.
Page 413 Feature Reference PRI is a common configuration for a DS1 facility. A DS1 facility consists of 24 channels, sometimes referred to as DS0 channels, each with a capacity of 64 kbps. DS1 refers to the twenty-four 64-kbps channels, plus framing and signaling bits, multiplexed together to form a 1.544-Mbps Digital Signal Level 1 signal.
Page 414 Feature Reference PRI must include a D-channel, but may include fewer than 23 B-channels. The remaining channels cannot be used for any other purpose. NOTE: The MERLIN LEGEND Communications System does not support multiple PRI trunks sharing one D-channel (as allowed with Non-Facility Associated Signaling).
Page 415 Feature Reference system’s toll restriction is guaranteed to be received by the far-end switch. A PRI line’s far-end disconnect signal provides a reliable indication when a call ends, and a new call cannot be initiated until the line has been released from the prior call on both ends. This prevents a user on a loop-start trunk, waiting off-hook for the restoration of dial tone after a previous call, from placing a second call before toll restriction is reapplied.
Page 416 Feature Reference the FTS2000 network prompts the user to enter the code from the telephone dialpad. The system allows an restriction code to be entered with the Account Code Entry feature.

A T1 line’s far-end disconnect signal provides a reliable indication when a call ends, and a new call cannot be initiated until the line has been released from the prior call on both ends.
Page 418 Feature Reference To connect the 100D module to an outside DS1 facility, a channel service unit (CSU) is used. The CSU regulates the transmission into and out of the 100D module so that the module matches the transmission of the outside facility. Both ends of the DS1 facility must be able to communicate.
Page 419 Feature Reference T1 is the factory setting and, when selected for the DS1 facility, allows each of the 24 channels to be programmed to emulate tie, loop-start, ground-start, or DID lines or Switched 56 in any combination. Therefore, a single 100D module can take the place of 24 regular outside trunks.
Page 420 Feature Reference ZCS line coding monitors each DS0 channel and prevents strings of eight or more zeros. Upon detecting eight consecutive zeros in a channel octet, ZCS line coding forcibly changes the seventh zero (the second least significant bit) to a one. The factory-set line coding is ZCS. B8ZS line coding matches the ones-density requirement by using a special sequence with a bipolar violation in bit positions 4 and 7.
Page 421 Feature Reference Line Compensation Line compensation adjusts for the amount of cable loss in decibels (dBs), based on the length of cable between the 100D module and the CSU or other far-end connection point. The factory setting is a value of 1, which allows a maximum loss of 0.6 dB.
Page 422 Feature Reference ESF framing should be used to take advantage of its improved maintenance, diagnostic, and testing capabilities. If the transmission between two systems is voice-only, RBS should be used for all 24 communication paths. For voice transmission, both ZCS and B8ZS line coding can be used to satisfy the ones-density requirement: the preferred line-coding format is B8ZS, which is needed for 64-kbps digital data.
Page 423 Feature Reference Copy Telephone Number to Send This option specifies whether or not the telephone number to send to the network for outgoing calls made on PRI lines assigned to a B-channel group is copied from the PRI telephone number assigned to that PRI line. Select the Copy Telephone Number to Send option when the telephone number sent to the network should match the number received from the network indicating the number dialed by the outside caller.

ARS selects the route and, in this case, the route points to a Call-by-Call B-channel group. 3. ARS performs digit deletion/addition operations for the route, and in so doing may indirectly specify the best service for the call.
Page 433 Feature Reference T1 Programming Options DS1 facilities programmed as T1 trunks can supply many types of connections. T1 service transmits and receives voice and analog data, as well as digital data in Release 4.0 communications systems. The connections can be to the Public Switched Telephone Network (PSTN), or they can be tie trunks to other MERLIN LEGEND Communications Systems or other PBX systems.
Page 434 Feature Reference Dial Mode The dial mode must be set for incoming calls (inmode) and outgoing calls (outmode). The dial mode (inmode or outmode) can be set to either Rotary (factory setting) or Touch-Tone. Touch-Tone Receivers are required on the remote communications system when the setting is set to Touch-Tone.
Page 435 Feature Reference NOTE: Most Local Exchange Carriers do not offer multiple telephone numbers associated with a single channel. Therefore, Routing by Dial Plan can only route calls to a single data extension per a single telephone number provided by the Local Exchange Carrier central office.
Page 436 Feature Reference In the event of a maintenance failure of primary synchronization, backup synchronization can be provided by secondary and tertiary clock synchronization. In addition, the source of synchronization is factory-set to Loop Clock Reference Source (the clock is synchronized to the external endpoint) or with a 100D module it can be set to Local Clock Reference Source (the clock is free-running).
Page 437 Feature Reference Behind Switch mode T1 data lines are not supported in Behind Switch mode. Considerations and Constraints General If a B-channel is not available when a call is placed, a fast busy tone is returned. While the tone is in progress, the line is considered busy. If the originator goes on hook while the tone continues, the call is ended and the line is idled.

Calls are delivered to the QCC operator in first-in first-out order, according to the queue priority level assigned to each type of call. If more than one QCC operator is available, the operator who has been idle the longest receives the call.
Page 457 Feature Reference The active call, or source , automatically goes on hold at the Source button (the green LED next to the Source button flashes). An outside caller hears Music On Hold, if programmed, or silence. An inside caller hears silence. The QCC operator hears a dial tone on the same Call button where the call had been active.
Page 458 Feature Reference QCC Features The MLX-20L telephone is the only telephone that can be assigned as a QCC. A QCC operator cannot use feature codes to activate features. Only the features that can be selected from the display or assigned permanently as buttons on the console can be used.

Page 463 Feature Reference For returning calls, the factory setting returns calls to the originating operator position (the initiator). The factory settings can be changed so that each type of call is directed to a different and/or additional QCC, or is not directed to any of the QCC operator positions.
Page 464 Feature Reference For example, if important customer calls are received on particular trunks, a priority value of 1 should be programmed so that the calls are answered before any others. Values of 2 through 7 should be assigned to trunks or call types used for less important calls.
Page 465 Feature Reference When Automatic Release is programmed and the QCC operator tries to direct a call to an invalid extension (such as a paging group), the display shows Denied: Cannot Release NOTES: 1. This message also appears immediately if the QCC operator presses the DSS button for Automatic Route Selection (ARS) or a pool dial-out code.
Page 466 Feature Reference Position Busy Backup The Position Busy Backup option designates a calling group to receive calls when all QCCs are in a position-busy state. Only calling groups can be designated as QCC position-busy backups. If no calling group is assigned to provide position-busy backup, the system does not allow the last QCC operator to use Position Busy.

Page 471 Feature Reference Conference When a QCC operator arranges a 3-participant conference (the QCC continued operator and two other participants) and then presses the Release button or hangs up, the QCC operator is released from the call and the other two participants remain connected. If the QCC operator arranges a 4- or 5-participant conference, the Release button is ignored and has no effect.
Page 472 Feature Reference Directories QCC operators use Directory features to dial extensions or telephone numbers with the touch of a button. The Extension Directory allows the operator to locate and dial system extension numbers. The System Directory and Personal Directory can be used to locate and dial outside numbers.
Page 473 Feature Reference Group Calling Only a calling group can be programmed to provide Position Busy backup when all QCC operators activate Position Busy. If no calling group is designated to provide backup, the system does not allow the last QCC operator to activate Position Busy. A QCC cannot be a member of a calling group.
Page 474 Feature Reference Inspect When a conference participant joins a conference call by using a shared outside line or a Shared SA button, the QCC display reflects the correct number of participants. However, if the QCC operator uses the Inspect feature to verify the number of participants, the number shown on the display does not include participants joining the conference call on Shared SA buttons.
Page 475 Feature Reference Paging A QCC cannot make or receive voice-announced inside calls (speakerphone calls to an individual extension). A QCC cannot be a member of a speakerphone paging group. A QCC operator can use a loudspeaker paging system only by selecting the feature from the display and can use the Group Paging feature by selecting a Call button and pressing the DSS button or dialing the extension for the paging group.
Page 476 Feature Reference Remote Access If a remote caller uses a rotary phone and the system does not require a barrier code, the call, after it times out, is sent to a QCC that is assigned as a backup station. One or more QCC operators can be assigned to receive calls on trunks programmed for shared remote access.
Page 477 Feature Reference Transfer The QCC operator uses the Start and Release buttons or a DSS button to transfer calls. However, pressing the Transfer button on a QCC is the same as pressing the Start button. A QCC operator cannot make or receive voice-announced transfers. When the operator uses the Start and Release buttons to transfer a call, the return ring interval applies for transfer return timing instead of the transfer return interval.

Page 479 Feature Reference On an outside call, when the system is using host switch services such as Centrex, the signal may be sent to the host, depending on the type of telephone and system operating mode. A multiline telephone user can use Recall to access host features. The user can be connected to another party or can be listening to outside dial tone, ringback, or a busy signal.
Page 480 Feature Reference When used after dialing is completed on an outside trunk, Recall sends a timed flash to the host switch, the trunk is kept, the user hears a new outside dial tone, and calling restrictions are reapplied. On an ARS call or a call on a rotary-dial trunk, Recall cannot be used until dialing is completed.
Page 481 Feature Reference If use of the communications system’s Conference, Drop, and Transfer features is also desired, they must be programmed on available line buttons on each multiline telephone through extension programming or centralized telephone programming. In Release 1.0 or 1.1, Recall cannot be used on any outside call made or received on an ICOM button.
Page 482 Feature Reference Single-Line Telephones A single-line telephone user without a Recall or Flash button must use the switchhook to send a timed flash. The communications system intercepts the signal; if it is to be sent on to a host switch, the system sends a signal of the duration programmed for the Recall timer.
Page 483 Feature Reference Automatic Route In Release 2.0 and later, Recall can be used on an ARS call. Recall Selection cannot be used during dialing. When dialing is completed, pressing the Recall button sends a timed flash to the host, the accessed trunk is kept, the user hears outside dial tone, and calling restrictions are reapplied.
Page 484 Feature Reference Forward and A multiline telephone user on an inside Forward or Follow Me call can Follow Me use Recall. In Release 2.0 and later, Recall can also be used on an outside call received on a loop-start trunk. Group Calling A user who has received an inside calling group call can use Recall.

Because voice-announced calls cannot be made to single-line telephones, a call made on this button to a single-line telephone is a ringing call even if the single-line telephone has a speakerphone. Originate Only. This button is used only to make inside calls. Calls are not received on this button.
Page 538 Feature Reference Shared SA buttons cannot be assigned to a single-line telephone. A single-line telephone cannot be the principal extension for a Shared SA button, unless the telephone is connected to an MFM. When two or more users answer the same call on a Shared SA button, the red and green LEDs next to the button go on, but only one person has a talk path with the caller.
Page 539 Feature Reference In Key and Behind Switch modes, each multiline telephone (including DLCs) and MFM device is automatically assigned one ICOM Ring and one ICOM Voice button. Single-Line Telephones In Hybrid/PBX mode, each single-line telephone (or other device connected to an 016, 012, or 008 OPT module) is automatically assigned two SA Ring buttons and one SA Originate Only button.

Feature Reference Additional extension jacks are shown in Figure 41 as Extra Extensions (6700–6842), and additional MFMs are shown as Extra Adjuncts (6850–6992). If extra extensions are assigned, the extension numbers for extra adjuncts are assigned by the system to MFM adjuncts. The extension number assigned to the MFM adjunct is the extension number assigned to the MLX telephone increased by 150.
Page 549 Feature Reference NOTE: Extensions 0 and 100 both refer to the same operator position in the 3-Digit Numbering Plan. Extensions default to 3-digit extension numbers beginning with 100 and ending with 243. The extension numbers shown for Multi-Function Modules (MFMs) (300-499) are reserved for MLX extension jacks.
Page 550 Feature Reference The extension numbers shown for Multi-Function Modules (7300-7499) are reserved for MLX extension jacks. These numbers are automatically assigned to adjuncts (such as modems, terminal adapters, answering machines, or fax machines) connected to an MLX telephone using an MFM. The actual extension number assigned to the adjunct is the extension number assigned to the MLX telephone increased by 200.
Page 551 Feature Reference Single Renumbering Single Renumbering should be used any time the extension numbers you are changing to or from are not sequential. Single Renumbering can be used to assign a specified extension number to the following: extensions, adjuncts, trunks, telephones, Automatic Route Selection Access Code, calling groups, Idle Line Access Code, Listed Directory Number, paging groups, park zones, Pools, and remote access code.
Page 552 Feature Reference In Release 1.0, when using single renumber to assign a specified extension number, the system is forced idle during the renumbering process.

Page 564 Feature Reference Transfer Options The sections below describe system-programmed options that determine how to transfer calls. Transfer Return Time If a transferred call is unanswered within a programmed number of rings, it rings back at the transfer originator’s telephone. This transfer return time can be set to a value of 1 to 9 rings, or 0 (the factory setting is 4 rings).
Page 565 Feature Reference With One-Touch Transfer, the system is also programmed to complete transfers in one of the following ways: Automatic Completion (the factory setting). A transfer is completed automatically as soon as the Auto Dial or DSS button is pressed. The call is removed from the telephone that initiated the transfer and begins ringing at the destination extension.
Page 566 Feature Reference If the system is programmed to select a ring button and one is available, the call rings at the destination extension. If the system is programmed to select a voice-announce button and one is available, the person at the destination extension hears a voice announcement.
Page 567 Feature Reference In Release 3.1 systems and later, an extension can have trunk-to-trunk transfers blocked through system programming whether or not the trunks involved are programmed for reliable disconnect. In Release 3.1 systems and later, all extensions are factory-set to be restricted from making trunk-to-trunk transfers.
Page 568 Feature Reference The transfer originator does not receive an error tone to indicate that the transfer was denied.

The call is transferred. If a single-line telephone with positive or timed disconnect is used, for example, AT&T models 2500YMGL and 2500MMGK, pressing the switchhook disconnects the call.
Page 571 Feature Reference Caller ID If a call comes in over a line connected to an 800 GS/LS-ID module and the customer subscribes to Caller ID service (loop-start lines/trunks only), when the call is transferred, the caller's telephone number is shown on Line 1 of the first screen. The extension that initiated the transfer is shown on Line 1 of the second screen.
Page 572 Feature Reference Direct Station DSS buttons can be used to transfer outside calls using One-Touch Selector Hold only by a DLC operator; a QCC operator cannot use this feature. When One-Touch Hold is programmed, if a DLC operator presses a DSS button with an inside caller on the line or, in Hybrid/PBX mode, with an outside caller on an SA button, the call is not put on hold.
Page 573 Feature Reference Forward/Follow Me Transferred inside and outside calls are forwarded. If a user transfers a call to an extension with Forward activated, the person receiving the forwarded calls hears one ring, indicating an inside call. In addition, if the person has a display telephone, he or she sees the call information for an inside call.
Page 574 Feature Reference Messaging A nondisplay telephone user who uses Leave Message to send a message while a transfer is in progress cannot determine who received the message. For example, suppose that Extension A calls Extension B, and Extension B transfers the call to Extension C. If Extension A sends a message before the transfer is completed, Extension B receives the message.
