Features Account Code Entry Extension Programming Programming Code: Feature Code: 82 + code MLX Display Label: AccoutCode [Acct] Description See "Station Message Detail Recording” Account Code Entry is used to enter account codes for outside calls (incoming in this ohapter for details on when and or outgoing).
Page 66: Feature Interactions
Features Single-Line Telephones On single-line telephones, Account Code Entry is activated during a call by putting the caller on hold, getting an internal dial tone, and dialing #82. (Dialing #82 is also necessary to activate the feature before a call.) The entry is completed by dialing #.
Page 67 Features When ARS is used on the system, an account code can be entered before or Automatic Route Selection after dialing the telephone number. If Forced Account Code Entry is assigned, the user must enter the oode before dialing the ARS dial-out code. Callback An account code must be entered before the user activates Callback.
Page 68 Features Speed Dial Multiline telephone users who use a programmed Account Code button or display telephone users who select the feature from the display can use Personal Speed Dial and System Speed Dial to dial account codes. Single-line telephone users and multiline telephone users who complete the entry by dialing a # cannot use Personal Speed Dial or System Speed Dial to dial account codes since the # required to use Speed Dial also completes Account Code Entry.
Page 69: Alarm
Features Alarm Extension Programming Programing Code: *759 MLX Display Label: Alarm [Alarm] Description Two alarms are available to provide either a visible or audible indication when the system detects a problem that can degrade service and, therefore, requires immediate attention: Alarm button.
Page 70 Features Feature Interactions Automatic Maintenance The red LED goes on next to the Alarm buttons on system operator consoles, Busy and the designated Maintenance Alarm alert device sounds or flashes when more than 50 percent of the trunks in the trunk pool are in a maintenance-busy state.
Page 71: Allowed Lists
Features Allowed Lists Description See "Calling Restrictions" in this chapter Assigned to individual telephones via system programming, an Allowed List is a for information on types of restrictions. list of telephone numbers that a user with an outward- or toll-restricted telephone can dial.
Page 72 Features Conference A user with an outward-restricted telephone cannot add an outside participant to a conference call unless the participant’s number is on an Allowed list assigned to the telephone. A user with a toll-restricted telephone cannot dial a toll number to add a participant unless the participant’s number is on an Allowed List assigned to the telephone.
Page 73 Features Speed Dial When a marked System Speed Dial number (the dialed number is suppressed from the display) is used to dial a number that includes a toll telephone number in addtion to an access number, using the System Speed Dial code to dial the number overrides any calling restrictions (such as toll or outward restrictions) assigned to the telephone.
Page 74: Auto Answer All
Features Auto Answer All Programming Code: *754 Extension Programming MLX Display Label: AutoAnsAll (centralized telephone programming only) Description See Chapter 5 for more information Auto Answer All is used on analog multiline telephones or analog direct-line about adjuncts and GPAs. consoles (DLCs) with an optional modem, answering machine, fax, or other answering device connected via a General Purpose Adapter (GPA).
Page 75: Auto Answer Intercom
Features Considerations When Auto Answer All is used, all voice announcements (including Voice Announce to Busy) should be disabled because the device connected to the GPA cannot answer voice-announced calls. Feature codes cannot be used to activate or deactivate Auto Answer All. Only analog multiline telephones and analog DLCs can use or be programmed for Auto Answer All.
Page 76 Features When Auto Answer All is activated, all calls received at an Intercom or System System Access Access Ring, or Intercom or System Access Voice button can be answered automatically by the device connected to the GPA. If Shared System Access buttons are assigned, only the principal station should be programmed for immediate Ring to prevent the call from being answered at the principal station and at stations with the Shared System Access button.
Page 77 Features Auto Answer Intercom Extension Programming Programming Code: *753 MLX Display Label: AutoAnsIcom (centralized telephone programming only) Description See Chapter 5 for more on the HFU. Some models of analog multiline telephones do not have a built-in speakerphone. Users with this type of telephone can still answer inside calls without lifting the handset by using Hands Free Answer on Intercom (HFAI).
Page 78 Features Feature Interactions Auto Answer All Both Auto Answer All and Auto Answer Intercom can be programmed on the same telephone, but they cannot be used at the same time. Coverage Auto Answer Intercom does not allow a receiver with an analog multiline telephone to use an HFU to answer calls received on a Primary Cover, Secondary Cover, or Group Cover button.

Page 80 Features Telephone Differences Queued Call Console Auto Dial buttons cannot be programmed on a queued call console (QCC). The Personal or System Directory can be used instead of outside Auto Dial buttons. The Extension Directory or DSS buttons can be used instead of inside Auto Dial buttons.
Page 81: Features
Features Considerations Auto Dial can be used only with a programmed button. MLX display telephone users can select the feature from the display only while programming the feature. A maximum of 28 digits can be programmed on reside or outside Auto Dial buttons.
Page 82 Features ARS dial-out codes cannot be programmed on inside Auto Dial buttons. An ARS Automatic Route Selection dial-out code can be programmed on an outside Auto Dial button when a telephone number is also included. Conference The Conference button is pressed to enter the Flash special character in a telephone number programmed on an Auto Dial button.
Page 83 Features A number dialed by pressing a programmed outside Auto Dial button is saved Last Number Dial for Last Number Dial as if it were dialed with the dialpad, but special characters do not work. An extension dialed by pressing a programmed inside Auto Dial button is not saved for Last Number Dial.
Page 84 Features System Access When an inside Auto Dial button is pressed, the system automatically selects an Intercom or System Access button and turns on the speakerphone. When outside Auto Dial button is pressed, the system automatically selects an outside line button in the Key mode, a Prime Line button in the Behind Switch mode, or a System Access button in the Hybrid/PBX mode.
Page 85: Automatic Line Selection
Features Automatic Line Selection Extension Programming Programming Code: Begin selection: E n d s e l e c t i o n * * 1 4 MLX Display Label (centralized telephone programming only): Begin selection: AutoLineSel E n d s e l e c t i o n : E n t e r Description Automatic Line selection is the programmed order in which the system makes...
Page 86 Features The Automatic Line Selection sequence for single-line telephones can be Single-Line Telephones changed only via centralized telephone programming and cannot be changed by the telephone user. The Automatic Line Selection sequence for single-line telephones and other tip/ring equipment connected to a 012 module or a Multi-Function Module (MFM) is factory set to include only the Intercom Ring or System Access Ring button..
Page 87 Features When outside lines/trunks or pools are assigned to a single-line telephone, they are automatically added to the Idle Line Preference sequence. To ensure that the correct sequence is selected, Automatic Line Selection should be programmed first if the user is programming additional features in one session.
Page 88: Automatic Maintenance Busy
Features Automatic Maintenance Busy Description When Automatic Maintenance Busy is enabled, a malfunctioning loop-start line/trunk, ground-start line/trunk or tie trunk is automatically put in a maintenance-busy state, preventing outside calls from being made on that line/trunk (incoming calls are never blocked). In general, there are two reasons an outside facility is put in a maintenance-busy state: Faulty or delayed signaling between the system and the central office.
Page 89 Features Considerations Incoming calls are received and processed normally on lines/trunks in a maintenance-busy state. Direct inward dialing (DID) trunks in the Hybrid/PBX mode are not affected by Automatic Maintenance Busy because these trunks can only receive calls. 100D (DS1) modules configured as ground-start line/trunks, loop-start lines/trunks, or tie trunks are monitored and maintained by Automatic Maintenance Busy.
Page 90: Automatic Route Selection
Features Automatic Route Selection Description Automatic Route Selection (ARS) provides preferred routing of calls over selected outside trunks based on the number dialed and the trunks available, With ARS, a Hybrid/PBX system can be programmed to route calls over the least expensive route available when the call is made.
Page 91 Features Note: Setting up 1 + 7 tables speeds call processing. However, users need to be instructed to dial the 1 if these tables are programmed and the ARS 1 + 7 dial setting is set to "within area code". If these tables are programmed and the 1 + 7 dial setting is set to “within area code,’...
Page 92 Features Other digits or special characters may be required so the system can route a call on a particular trunk pool. For example, some companies use an alternate toll company that requires dialing of the telephone number with pauses and access codes.
Page 93: Ars Process
Features If the telephone’s FRL is equal to or greater than the FRL of the first route (for example, the telephone’s FRL is 4 and the route’s FRL is 3) and if the route is available, the call is put through. If the route is busy, the FRL of the second route is checked and, if the telephone has the appropriate FRL the call is put through.
Page 94 Features Mode Differences ARS can be used only on systems that operate in Hybrid/PBX mode with trunk pools. Considerations ARS users must dial a dial-out code (usually 9) to gain access to an outside trunk. The factory setting for the ARS dial-out code is 9. Once a user has dialed the ARS dial-out code, he or she will hear beeps instead of tones as the rest of the number is dialed.
Page 95 Features Feature Interactions Account Code Entry When ARS is used on the system, an account code can be entered before or after dialing the telephone number. Allowed Lists ARS checks calling restrictions before choosing the route for a call. This prevents users with restricted telephones from dialing numbers that are not included on an Allowed List.
Page 96 Features Forward and Follow Me ARS can be used to select the facility on which to forward calls to an outside telephone number. The user enters the ARS code before the telephone number. The FRL for the call is that of the telephone from which calls are being forwarded.
Page 97 Features Toll Type In certain areas the local telephone company requires dialing the prefix 1 for certain exchanges. In these cases, the exchanges can be assigned to a 1 + 7 ARS table and the 1 + 7 dial setting must be set to ‘within area code’ so that people calling numbers in the exchanges do not have to dial the 1.
Page 98 Features Specify the FRL and/or digits that must be added when people dial emergency numbers in the special number or N11 table. Tables-> ARS -> More -> SpeclNumber -> ARS FRL or ARS D i g i t Specify the pool routing, FRL, and digits or special characters that must be added by the system to the number dialed by the user when calls are routed on the dial 0 table.
Page 99: Barge-In
Features Barge-In Centralized Telephone Programming Code: *58 Programming MLX Display Label: Barge In Description Barge-In allows a user to contact a co-worker in an emergency or if the user has been given special instructions to interrupt. If the extension is busy, Barge-in bridges the user onto the call.
Page 100: Callback
Features All Other Multiline To use Barge-In on all other multiline telephones, the user dials the extension number then presses a programmed Barge-In button or presses the Feature Telephones button and dials 58. On an MLX display telephone, the user can also press the Feature button and select Barge-In from the display.
Page 101 Features When a forwarded call is answered at the destination station, Barge-In can be Forward and Follow Me used to join the call only by dialing the extension number for the destination station (not the extension for the originating station). Barge-In cannot be used to join a call forwarded to an outside telephone number.

Page 103: Telephone Differences
Features If the user hangs up, the green LED flashes next to the Intercom or System Access button used to make the call to indicate that the call is on hold. When the busy extension or pool is available, the user hears a priority ring (four bursts of ring on an MLX telephone and three bursts of ring on an analog multiline telephone and single-line telephone).
Page 104: Calling Restrictions
Features Considerations Callback cannot be used for lines or pools assigned to buttons on a telephone. No more than 40 dialed digits can be included in a queued call. A maximum of 64 calls can be queued in the system at one time. A user who tries to queue the 65th call receives a busy tone.
Page 105: Conference
Features With Automatic Callback, the call is automatically queued; however, if the user Conference tries to add the queued call to the conference, the system returns a busy tone. If a user with Selective Callback tries to queue a call while setting up a conference, the system returns a busy tone.
Page 106 Features Group Calling Calls made to a calling group are not eligible for Callback since the call rings into the calling group’s queue. However, Callback can be used for calls to individual calling group member extensions or to the delay announcement device.
Page 107 Features Pools Callback can be used to complete calls to outside numbers in the Hybrid/PBX mode only when the call is made by using a pool in which all trunks in the pool are busy. Queued Call Console Calls to QCCs are not eligible for Callback since the calls ring into the QCC queue.
Page 108 Features When the extension is available, the call is transferred to the extension automatically. If the extension is not available before the Transfer Return interval expires, the call is removed from the Callback queue and returned to the originator. If a single-line telephone user with a call queued for a busy station completes a transfer to a busy pool, the caller hears a fast busy tone.
Page 109 Features Calling Restrictions Description Calling restrictions help a company manage communications costs and resources. Through calling restrictions, users at individual telephones can be restricted from making certain types of calls: Outward Restriction. The telephone cannot be used to make outside calls. Incoming calls can be answered and inside calls can be made and received.
Page 110 Features Considerations In the Hybrid/PBX mode, an outward-restricted telephone cannot be used to make an ARS call except to emergency numbers. Users with Pool buttons on their telephones can use the pool even if the pool dial-out restriction is assigned to the telephone. Only outgoing calls are affected;...
Page 111: Direct-Line Console
Features A user with an outward-restricted or toll-restricted telephone cannot add an Considerations outside participant to a conference unless the participant’s number is on an Allowed List assigned to the telephone. However, if a conference originator with an outside caller presses the Conference button, selects an outside line, and presses the Conference button again before dialing a number, the outside caller can dial a toll call, thereby overriding calling restrictions assigned to the conference originator’s telephone.
Page 112 Features Pools Specific pools can be restricted from being used for outgoing calls by assigning a pool dial-out code restriction to telephones. Queued Call Console Calling restrictions can be assigned to QCCs. Since calling restrictions apply to telephones used to initiate a call transfer to an outside number, a user with a restricted telephone can circumvent restrictions by asking a system operator with an unrestricted console to connect an outside call.

Page 115 Features The user receiving the Call Waiting tone has these options: Ignore the new call and continue with the current call. The caller continues to hear the special ringback. Complete the current call, hang up, and answer the waiting call when it rings. The caller hears normal ringback.
Page 116 Features If a multiline telephone in the Key or Behind Switch mode does not have an Key and Behind Switch Intercom Originate Only button assigned or available, the user cannot pickup the waiting call. Considerations Call Waiting is not activated if a line button of the appropriate type (such as Intercom or System Access) is available to receive a call.
Page 117 Features Direct-Line Console When the DLC system operator uses Camp-On to transfer a call to a busy extension, the call is placed in the Call Waiting queue and the caller hears the Call Waiting tone whether or not the extension has the Call Waiting feature activated.
Page 118 Features Reminder Service calls are not eligible for Call Waiting. Reminder Service Station Message Detail SMDR does not begin measuring the duration of Call Waiting calls until the call Recording is answered. System Access A telephone is considered busy when all Intercom or System Access (excluding Intercom or System Access Originate Only) buttons are in use.

Features C a m p - O n Programing Code: Extension Programming F e a t u r e C o d e : MLX Labels: Camp On [Camp] Description Camp-On allows a user to complete a transfer to a busy telephone. The call is put on hold until the telephone can receive a call, then rings through automatically.
Page 120: Direct Station Selector
Features Considerations A Camp-On Return interval of 30-300 seconds in increments of 10 seconds can be programmed. The factory setting is 90 seconds. Using Camp-On to complete a Transfer to a busy extension permits calls to wait for a longer period before the call returns to the originator (up to 300 seconds).

Conference calls originated from multiline telephones can have a total of five participants-the originator plus two outside lines and two extensions.
Page 124 Features Telephone Differences Queued Call Console A QCC system operator arranges a conference call by pressing the Conference button after receiving a call or dialing the first outside number or extension. The green LED next to the Call button flashes to indicate the person is on hold for the conference.
Page 125 Features To add another person, the user presses the Conference button again. The green LED next to the line buttons flash, but the participants can converse. The originator can continue to add participants by pressing the Conference button, selecting a line or dialing the number, and pressing the Conference button until up to two outside lines and three extensions (including the conference Originator) are in the conference.
Page 126 Features Considerations Transmission quality may vary during the conferencing of outside lines. A call to a busy number cannot be added to a conference. Pressing the Drop button and the line button for a participant also disconnects a participant who joined the conference by using a shared outside line or System Access button.
Page 127 Features Allowed Lists and A user with an outward-restricted telephone cannot add an outside participant to a conference unless the participant’s number is on an Allowed List assigned Calling Restrictions to the telephone. A user with a toll-restricted telephone cannot dial a toll number to add a participant unless the participant’s number is on an Allowed List assigned to the telephone.
Page 128: Disallowed Lists
Features Coverage Conference calls can be originated from a Cover button only when the user with a caller on the Cover button presses the Transfer button, dials the number for another person, and then presses Conference to complete the transfer. In this case only, instead of the call being transferred, a conference call with three participants (including the originator) is established.
Page 129 Features Hold The conference originator receives the Hold Reminder tone when the conference is on hold for more than one minute as a result of using the Hold button or adding other participants. If DLC Operator Automatic Hold is programmed and used by a DLC system operator setting up a conference, the entire conference goes on hold.

Page 143 Features Telephone Differences Multiline Telephones Any type of multiline telephone except a QCC can be a sender and/or receiver for either Individual Coverage or Group Coverage. Single-Line Telephones A single-line telephone can be a sender. A single-line telephone cannot be a receiver for Individual Coverage and can be a receiver for Group Coverage only when the single-line telephone is assigned as a member of a calling group.
Page 144 Features When Group Coverage is the only type of coverage programmed for a sender, the QCC queue should not be programmed in addition to Group Cover buttons because coverage calls received by a QCC system operator cannot be programmed for Delayed Ring. Therefore, eligible calls ring immediately both at the sender’s telephone and at the QCC queue.
Page 145 Features If a sender calls a receiver, the call follows any individual or Group Coverage pattern programmed for the receiver. However, if a receiver calls an unavailable sender, the call is sent to an individual or Group Coverage receiver programmed for the sender. If the sender is available, the call is not sent to individual or Group Coverage receivers.
Page 146: Display
Features Call Waiting A call to a sender with Call Waiting activated goes to Individual and/or Group Coverage first. If all coverage areas are busy, the sender receives the Call Waiting tone. If a sender uses Coverage On/Off to prevent calls from going to Coverage receivers after hearing a Call Waiting tone, the waiting call does not go to Coverage, but subsequent calls do.
Page 147: Group Calling
Features When a sender forwards calls, the calls go to Coverage at the same time. Calls Forward and Follow Me received on a Primary Cover, Secondary Cover, or Group Cover button cannot be forwarded. Group Calling A calling group cannot be programmed as a receiver for Individual Coverage. A coverage group can have only one calling group as a receiver.
Page 148 Features Once a receiver answers a call received on a personal line on a Cover button and puts the call on hold, the sender and any other user who shares the personal line cannot pickup the call by pressing the Personal line button. For proper handling, the receiver should transfer the call to the sender.
Page 149 Features Primary Cover, Secondary Cover, and Group Cover buttons can be Ringing Options programmed for Immediate Ring, Delayed Ring, or No Ring. If an Individual or Group Coverage receiver is on a call when a coverage call is received, the receiver hears an abbreviated ring (if Abbreviated Ring is enabled).
Page 150 Features System Programming Assign extensions to Group Coverage sender groups. Extension -> More -> Group Cover Assign calling group as a Group Coverage receiver. Extension -> More -> Grp Calling -> Coverage Assign or remove principal user of a personal line. This specifies that calls received on the personal line follow only the individual extension’s Coverage patterns and not the Coverage patterns of other users who share the line.

Page 239 Features Callback Calls made to a calling group are not eligible for Callback since the call rings into the calling group’s queue. However, Callback can be used for calls to individual calling group member extensions or to the delay announcement device.
Page 240 Features 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 241 Features An MFM can be a member of a calling group, can be assigned as a delay Multi-Function Module announcement for a calling group, or can be used to connect the calls-in-queue alert for the calling group. An MFM that is used for the delay announcement or calls-in-queue alert should not be assigned as a group member.
Page 242 Features If all QCC system operators activate Position Busy while an overflow call is in the QCC queue, the call is re-routed to the original calling group and not to the calling group providing Position Busy backup. Remote Access Remote Access users cannot log into a calling group but a Remote Access user can call into a calling group regardless of the restrictions applied.
Page 243 Features Transfer A call transferred to a calling group is not returned to the originator; the call is handled like any other call received in the calling group. For example, the system follows the same hunt sequence to locate an available calling group member and the call is eligible for a delay announcement if one is programmed.

Before Headset Hang Up can be used, headset operation must be activated either automatically following centralized programming of a Headset Hang Up button or manually by using a Headset Status button.
Page 249 Features When a telephone or console has a Headset Hang Up button, Headset Status is needed only to manually activate and deactivate headset operation when the user wants to switch between using a headset and using a handset. If a user with active Headset Auto Answer presses the button with a ringing call, the call is answered without the user hearing the tone.
Page 250 Features If the MLX telephone user with Headset Auto Answer uses Do Not Disturb, any Do Not Disturb calls that override Do Not Disturb (such as Barge-In calls and Callback calls) are automatically answered. Hold Headset Auto Answer is automatically deactivated when an MLX telephone user puts a call on hold and must be reactivated manually.
Page 251 Features Hold Extension Programming Feature Codes: Hold Hold Release Description Hold allows a user to leave a call temporarily to take a second call, retrieve information, activate a feature (such as Conference), or greet a visitor. When a user (excluding a QCC system operator) puts an outside call on hold, the green LED next to the line button flashes at a faster rate to distinguish the call from calls put on hold by other users.
Page 252 Features Considerations The factory setting for the Hold Disconnect Interval is the long interval (450 ms) since it is the interval used by most telephone companies. If the Hold Disconnect Interval of the system does not match that of the central office, the system may have the following problems with calls on hold: If the interval is shorter than the setting at the local central office, callers on hold may be disconnected.
Page 253 Features Coverage Coverage calls answered by any type of receiver can be put on hold. The Hold Reminder applies to any calls put on hold on a Primary Cover, Secondary Cover, or Group Cover button. Direct-Line Console When programmed system wide, DLC Operator Automatic Hold puts an active call on hold when the DLC system operator presses another line button.
Page 254 Features If a single-line telephone user with a call on hold hangs up, the call is Park disconnected; therefore Park should be used instead of Hold.

The top two buttons on each side are labeled and have the same functions in every screen. They are Home, Menu, More, and Inspect. The next five unlabeled buttons on each side are used to select options from a menu displayed on the screen.
Page 332: System Programming And Maintenance (Spm) Display
Features Detailed information on connecting and The advantage of programming the system with a PC is that all programming programming via a PC with System can be backed up on a floppy or hard disk. This makes recovery of system Programming and Maintenance is in programming fast and effortless in the event of an inadvertent system shutdown System Programming.
Page 333 Features PC-based SPM programming via a modem can be done either on-site or from a On-Site and Remote remote location. In both cases, the built-in modem of the control unit is used. Programming Accessing the modem for on-site programming is done by dialing the code for the control unit’s modem, which establishes connection to the system programming jack.
Page 334 Features Queued Call Console Description The queued call console (QCC) is an answering position available only in the Hybrid/PBX mode. The QCC is used by system operators to: Answer outside calls that are directed to a system operator position. Answer inside calls. Extend inside and outside calls to an extension or an outside telephone number.
Page 335 Features Both inside and outside calls ring on Call buttons on the QCC. Unlike the direct-line console (DLC) on which many incoming calls can ring simultaneously. the QCC receives one call at a time, regardless of the number of incoming calls to the system.
Page 336: Qcc Fixed Features Assigned To Line Buttons
Features The buttons on the QCC are factory-set with fixed features and cannot be programmed by the system operator or through centralized programming. The QCC fixed-feature buttons are shown in Figure 2-17. Figure 2-17 QCC Fixed Features Assigned to Line Buttons Call.
Page 337 Features Headset Mute (Headset/Handset Mute). Activates or deactivates the headset or handset microphone.

Page 340 Features If the calls are not directed to a system operator position and a user dials 0 or the Listed Directory Number, the caller hears a fast busy if the call was made on a DID or dial-in tie trunk, or by a Remote Access user. On other types of lines, the caller hears an error tone.
Page 341 Features The Queue Over Threshold is the maximum number of calls allowed in the QCC Queue Over Threshold queue before all QCC system operators are warned that many unanswered calls are waiting in the queue. The factory setting i 0, which means system operators are not notified when calls are in the QCC queue.
Page 342 Features When Automatic Release is programmed and the system operator tries to transfer a call to an invalid extension (such as a paging group), the display shows “Denied: Cannot Release.” This message also appears immediately (and does not time out) if the system operator presses the DSS button for the ARS or a pool dial-out code.
Page 343: Maximum Number Of System Operator Positions
Features Considerations The MLX-20L telephone is the only telephone that can be used as a QCC. No more than four QCCs are allowed in a system. A maximum of two QCCs can be assigned can each 008 MLX module. A QCC can be connected only on the first and fifth station jack on each module.
Page 344 Features Trunks assigned to ring into the QCC queue can also be assigned as personal lines on one or more telephones. Only one split condition can be active at any given time on a QCC console. When a system operator on a call wants to make an outgoing call, he or she should press the Position Busy button before pressing the Hold button to temporarily make the console unavailable for calls from the queue.
Page 345 Features Feature Interactions Account Code Entry A QCC system operator can activate Account Code Entry only by selecting the feature from the display and not through the use of feature codes. Normally, account codes cannot be entered when a Group Coverage call is answered at a Coverage button programmed on a multiline telephone.
Page 346 Features Call Waiting, A QCC system operator can release a call to a busy extension by selecting Camp-On from the display or by pressing the Release button. If Camp-On is Camp-On used, the call does not return to the QCC queue until the Camp-On return interval expires.
Page 347 Features Direct-Line Console Both DLCs and QCCs can be assigned in the Hybrid/PBX mode. The maximum combined number of system operator positions is eight; no more than four can be QCCs. In a system with both DLC and QCC positions, the primary system operator position must be a QCC.
Page 348 Features Forward and Follow Me A QCC system operator cannot forward calls to extensions or telephone numbers. The system operator uses Position Busy instead to send calls to a backup calling group. Calls that are forwarded to an individual QCC system operator or Follow Me calls that are signed in to a QCC can be assigned a queue priority.
Page 349 Features If the QCC system operator does not pick up a call by the time the hold timer expires twice, the call can be programmed to either remain on hold or return to the QCC queue. When the QCC Hold Return Option is set for calls to remain on hold indefinitely, the system operator hears the abbreviated ring every time the interval expires if no call is ringing on the console.
Page 350 Features When multiple Night Service calls are received in the QCC queue at the same time and none of the calls are answered by a Night Service member (all group member Intercom or System Access buttons are busy), new calls are sent to the QCC queue and can be answered only by the QCC system operator.

Page 362 Features Remote Access Description The Remote Access feature allows employees to dial into the system by dialing the number of a line or trunk designated for Remote Access. The remote user should be required to dial a barrier code (password) after reaching the system. After gaining access to the system, the remote user can: Dial extension numbers directly without going through the system operator.
Page 363 Features Barrier Codes To help safeguard against unauthorized system access, the system can be programmed to require that remote users enter a barrier code before gaining access to the system. AT&T strongly recommends the use of barrier codes. Note: Under applicable tariffs, the customer is responsible for any charges incurred through the remote use of system facilities.
Page 364 Features Allowed List Assignment. Used Remote Access users are restricted when from making local and/or toll calls. Up to eight Allowed Lists enable restricted Remote Access users to call specific numbers (local or toll). When barrier codes are not used, Allowed Lists are assigned to all lines/trunks and cannot be assigned to individual lines/trunks.
Page 365 Features Feature Interactions Account Code Entry Account codes cannot be entered on calls made via Remote Access. Allowed Lists An Allowed List is one of the class of restriction (COR) items for Remote Access. When barrier codes are not used, Allowed Lists are assigned to lines/trunks system wide.
Page 366 Features If the user wants to forward calls to an extension, the user then dials #33 followed by the extension number. If the user wants to forward calls to an outside telephone number, the user dials #33, selects the line/trunk or pool on which to forward the call by dialing either the Automatic Route Selection (ARS), the pool dial-out code (Hybrid/PBX only), the Idle Line access code (9 for Key and Behind Switch only), or the line/trunk number (801-880).
Page 367 Features If the caller uses Remote Access to dial out on a line or trunk, the “Station” field is blank on the first SMDR record and a second record is generated for the outgoing call. A Remote Access user cannot enter account codes. However, if a Remote Access user calls an inside extension and the person at that extension enters an account code, the code overrides the barrier code number (00-16) printed in the Account Code column.

Features Transfer Description Transfer allows a user to direct an inside or outside call to another extension (including extensions assigned as a fax port) or to an outside number. Transfering outside calls to outside numbers is called "Trunk-to-Trunk Transfer." There are three types of transfer Consultation Transfer.
Page 421 Features One-Touch Hold. When the Transfer button is pressed to initiate a transfer, the outside caller is put on hold. The person transferring the call dials the extension number or presses an Auto Dial or DSS button, and then either presses Transfer again, selects another line button, or hangs up to complete the transfer.
Page 422 Features Telephone Differences Multiline Telephones To make a consultation transfer, the multiline telephone user presses the Transfer button, or if the system is programmed with One-Touch Transfer with manual completion, the user just presses an Auto Dial or DSS button. In either case, the call is automatically put on hold and the system selects either a System Access or Intercom Voice button, or System Access or Intercom Ring button.
Page 423 Features Mode Differences One-Touch Hold is the factory setting in the Behind Switch mode. One-Touch Transfer cannot be programmed in the Behind Switch mode. The selection of the option is not blocked in system programming; however, the setting is always One-Touch Hold regardless of which option is chosen.
Page 424 Features If a single-line telephone with a timed disconnect is used (for example AT&T models 2500YMGK-PEC3178-NHL and 2500MMGK—PEC3101-ETR), pressing the switchhook automatically disconnects the call. With this type of telephone, the Recall button must be used instead of the swltchhook to transfer a call.
Page 425 Features When a call is transferred to an extension programmed as a fax port, the call is not returned to the originator and continues to ring at the fax extension. This eliminates the possibility that the high-pitched fax tone would be heard by a person who answers the transferred call.
Page 426 Features Camp-On A transfer can be completed by using the Camp-On feature whether or not the destination extension is busy. When the feature is used, the Camp-On Return Interval is used instead of the Transfer Return Interval. The Camp-On Return Interval is normally longer.
Page 427 Features Calls returning from a transfer are identified by call type and by the name and extension number to which the call was transferred. The second line of the display also shows the caller information. When an MLX display telephone user receives a transferred call, the display shows the type of call and the caller information on line 1.
Page 428 Features Hold Calls on hold for transfer are also timed so that the user or system operator hears a reminder after the timer expires. If a call is received on a personal line and is transferred to another user who then puts the call on hold, another user who shares the personal line cannot select the line button to pick up the call.
Page 429 Features A user can park calls by pressing the Transfer button and dialing his or her own Park extension or, for DLC system operators, by dialing a system operator park zone. When using this method, the transfer must be completed by pressing the Transfer button or by hanging up.
Page 430 Features In the Hybrid/PBX mode, a transferred call that returns to the principal station does not ring on any of the Shared System Access buttons programmed for the button on which the call is returning. If a transfer originator has a Shared System Access button for the person receiving the transfer, the LED next to the Shared System Access button flashes to indicate a ringing call.

Page 445: Call Management System
System Applications Call Management System The Call Management System (CMS) is an MS-DOS-based software application that simulates the actions of a system operator by answering calls and distributing them to individual agent telephones. If no agents are available, CMS puts calls on hold and, if programmed, plays a recorded announcement to the callers such as, "Thank you for calling the ABC Company.
Page 446 System Applications Mode Differences CMS cannot be connected to a communications system that operates in the Behind Switch mode. Considerations CMS can handle calls for up to 28 agents on up to 28 lines, and it can answer calls on two lines at the same time with the same announcement. There can be up to six agent splits with 28 agents per split.
Page 447 System Applications System Feature Interactions Extention Status A CMS supervisor uses the Extension Status feature to control and monitor when agents are in the available, unavailable, or ACW state.

Page 457: Merlin Attendant
System Applications MERLIN Attendant The MERLIN Attendant is a stand-alone application product that provides system operator-like services via prerecorded messages and electronic switching. The Attendant automatically answers incoming calls on designated lines with a recorded greeting and transfers these calls to extensions or departments based on information provided by the caller.
Page 458 System Applications A maximum of four Attendants can be connected to the communications system. The Attendant can answer every call that comes in or just answer calls that ring on certain lines. Unanswered transferred calls do not return to the Attendant; they are redirected to a designated extension, such as the system operator.
Page 459 System Applications Privacy must be programmed for each station jack that has an Attendant Privacy connected to it. Transfer VMI ports can transfer an incoming call to an outgoing line/trunk. If a caller incorrectly specifies the answering VMI port as the desired transfer destination station, the VMI port can inadvertently park the call.
Page 460: Merlin Mail Voice Messaging System
System Applications MERLIN MAIL Voice Messaging System The MERLIN Mail Voice Messaging System offers integrated call management services at low cost. Its services are as follows: Automated Attendant. Telephones are answered automatically and callers are transferred to the appropriate departments or extensions. Callers dial numbers on a touch-tone telephone to respond to a series of recorded prompts.
Page 461: Merlin Mail Ports Required
System Applications The number of incoming lines and subscribers programmed for Automated Attendant service and the number of busy-hour calls determine how many MERLIN MAIL ports are required for the user’s system (see Table 3-5). Table 3-5 MERLIN MAIL Ports Required New Application Features The MERLIN MAIL Voice Messaging System features that are new for the MERLIN LEGEND Communications System include the following:...
Page 462 System Applications When users receive voice-mail messages, the message LEDs on their telephones turn on, provided that a mailbox has been assigned to each of those telephones. Callers who dial from rotary telephones cannot use the features of the MERLIN MAIL Voice Messaging System and should be directed to the system operator during business hours.

Page 472 Functional Description Input/Output Bus. The I/O bus contains a 16-bit address bus and an 8-bit data bus. The address bus selects the module that receives instructions from the 68000 microprocessor in the processor module. The microprocessor provides instructions to the port processors and DSEs through the 8-bit data bus.
Page 473 Functional Description Quantizing causes distortion due in part to the "rounding off" of PAM samples into discrete PCM values. This distortion can be minimized by increasing the number of bits used to encode each PAM sample or by increasing the sampling rate.
Page 474 Functional Description Tie trunks transmit via three different signaling formats, each made up of a Tie-Trunk Signaling specific mode and a specific type. The dual in-line packaging (DIP) switches on the 400EM module select the signaling modes needed for tie-trunk transmission; the signaling type is selected during system programming.

The following features are not available on a Key system: t r u n k p o o l s...
Page 478 Functional Description The following types of Intercom buttons can be used to make and receive inside calls in the Key mode: Intercom Ring button is used to make inside calls and to receive inside calls and outside calls transferred by another user. When an Intercom Ring button is used to make an inside call, the call rings with a one-burst ring to indicate an inside call.
Page 479: Lines Labeled For Modified Key System Telephones
Functional Description Modified Key System A square Key system can be modified through system programming to provide line access for special business needs. For example, because in many offices not every user needs a tie trunk, the system is programmed so that not all telephones have access to all lines.
Page 480 Functional Description KF Classification The system is registered under the KF classification in the following cases: All outside lines terminate on one or more telephones. All outside lines to the system are loop-start, tie, or a DS1 facility (or any combination).
Page 481 Functional Description Hybrid/PBX Mode A PBX (private branch exchange) originally was a large switchboard installed at a customer’s office that functioned like a small, self-contained telephone company. The switchboard was manually operated, and the system operators had to physically connect calls by plugging cords into the board’s jacks. Today’s PBX is a processor in the system’s control unit programmed to connect both inside and outside calls on a single button.
Page 482: Hybrid/Pbx Mode Of Operation
Functional Description Figure 4-4 Hybrid/PBX Mode of Operation Outside calls are normally answered by a system operator and transferred to individual system users. A feature commonly used with pools is Automatic Route Selection (ARS). When a System Access button is used to make an outside call and the ARS dial- out code (usually a 9) is entered, the system selects the next available trunk from the type of pool best suited for the call assigns it to the user’s telephone for that call...
Page 483 Functional Description Without additional programming, the system provides three types of trunk pools The system’s trunks are automatically assigned to the corresponding trunk type pool. The three automatic trunk pools are loop-start pool (also called the main pool); the factory-assigned pool number is 70.
Page 484 Functional Description Shared System Access buttons are often provided to secretaries and their bosses, as well as to others who work closely together, such as a customer service department. For inside calls, the button can be programmed for either voice or ring operation. Pool buttons are used to make outside calls using a specific trunk pool.
Page 485 Functional Description Hybrid/PBX Operating in the HybridPBX mode offers several advantages: Considerations Hybrid/PBX trunks are the most efficient use of outside trunks since they can be pooled and are more readily available to users. The ARS feature can be programmed for more cost-effective use of pools. Cost-effective single-line telephones can be used for greater functionality than is possible in other modes.
Page 486: Behind Switch Mode
Functional Description Figure 4-5 Behind Switch Mode Modifications In addition to accessing the pool of outside lines in the host switch, the system can be modified to bypass the host switch and provide direct access to outside lines—for example, to connect WATS lines directly to the control unit so that they are available only for users in the Behind Switch mode (see Figure 4-6).
Page 487: Behind Switch Mode With Direct Outside Lines
Functional Description Figure 4-6 Behind Switch Mode with Direct Outside Lines Depending on business needs, any one (or a combination) of the following direct outside lines can be added: loop-start (basic, WATS, FX) tie trunks DS1 facility The direct outside lines must be terminated on individual telephones and must appear on the telephones’...
Page 488: Labeled Line Buttons For Behind Switch Telephones
Functional Description Figure 4-7 Labeled Line Buttons for Behind Switch Telephones The bottom button on each telephone is reserved for the Prime Line coming from the host system. The outside lines appear on the labeled line buttons above the Prime Line. In this figure, the first line (5678) is assigned to buttons on both telephones, and the second (5679) is assigned to a button only on the second telephone.
Page 489 Functional Description In a Behind Switch system the Intercom buttons on the telephones allow users to call other people connected to the system. When an Intercom button is pressed, the system provides an inside talk path and dial tone from the Behind Switch system (not the host system).
Page 490 Functional Description FCC Registration The FCC has no Behind Switch classification, so the system is registered under the FCC category it parallels-either KF (a Key system) or MF (a hybrid system). The AT&T account representative or authorized dealer who planned the system’s mode of operation provides the FCC registration number that the customer reports to the local telephone company.

Loop-Start Line/Trunks Loop-start lines/trunks are the standard for home and small business Key systems. They are less expensive in some areas but have certain limitations: They do not protect against glare. (Glare occurs when a person tries to make an outside call on a line/trunk at the same time an incoming call is being received on that line/trunk.) They can have higher cable losses and, therefore, transmissions of less...
Page 493 Functional Description The following tie-trunk options need to be programmed via system programming: E&M Signaling Type Type 1 standard (the factory setting) — used when tie trunks are connected to the other system through the local telephone company. Type 1 compatible — used when tie trunks are connected directly to a system that uses type IS signaling and is located near this system.
Page 494 Functional Description Delay — The originating end of the tie trunk transmits an off-hook signal and waits for the remote end to send an off-hook signal followed by an on-hook signal. Automatic — Incoming calls are routed directly to another station without a start signal.
Page 495 Functional Description No routing of calls is made until the designated number of digits is received. Incoming DID numbers that don’t match a valid extension are either directed to a predesignated extension, such as the system console, or the system sends back a reorder tone.
Page 496: Ds1 Facilities
Functional Description DS1 Facilities A Digital Signal 1 (DS1) facility is a transmission system that transports digital signals in the DS1 format. The interface that allows the connection of DS1 facilities to the system is the 100D module. Through this module, voice and data calls can be made or received using a DS1 facility.
Page 497 Functional Description Any combination of the following AT&T Switched Network (ASN) Services can be provided through a T1 or ISDN-PRI line/trunk Megacom® WATS service for domestic long-distance outward voice calls; ISDN-PRI on the MERLIN LEGEND Communications System does not support access to international Megacom WATS service. Megacom 800 for domestic toll-free incoming voice calls.
Page 498 Functional Description ISDN-PRI ISDN-PRI is a standard format for ISDN service. Some of the benefits of ISDN- PRI service are Speed. Data calls to outside destinations can be established on the same B channels used for voice calls if the service allows. Modems and dedicated, conditioned lines/trunks are not needed.
Page 499 Functional Description Line Coding The DS1 signal consists of a continuous bit stream of ones and zeros, encoded into bipolar pulses for transmission. Only the ones create a pulse; the zeros represent the absence of a pulse. The pulses of the ones alternate between positive and negative.
Page 500: Line Compensation Settings
Functional Description 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 501: Signaling Mode
Functional Description Signaling Mode Signaling is the process of communicating channel-state information (such as dialing) from endpoint to endpoint. Two types of signaling can be used in T1 transmission: robbed-bit signaling (RBS) and common-channel signaling (CCS). Choosing a signaling mode pertains only to T1 service; ISDN-PRI always uses common channel signaling (23 B channels and 1 D channel).
Page 502: System Alarms
Functional Description System Alarms An alarm condition detected by the system can cause the control unit to activate contact closures at a ground-start or loop-start port (administration of a loop start port is preferred). When the contacts close, a signal is passed on to a Universal Paging Access Module (UPAM) and then to an external alert.
