Page 67 Lines DS1 Facility (100D Module) Use these instructions only if the system has a 100D module. Because of the complexity of DS1 facility planning, consult with your AT&T representative or authorized dealer as you work through these instructions. A Digital Signal 1 (DS1) facility is a transmission system that transports digital signals in the DS1 format.
Page 68: Services On The Ds1 Facility
Lines Type of Service The system supports two types of service for DS1 facilities: T1 and Integrated Services Digital Network Primary Rate Interface (ISDN-PRI). T1 service (the factory setting) transmits and receives voice, and analog data; ISDN-PRI transmits and receives voice and analog and digital data. Table 3-3 shows the kinds of services available through a DS1 facility and specifies the type of service that supports them.
Page 69 Lines Table 3-3 Continued ISDN-PRI Description Service A virtual private networking service Software Defined Network (SDN) for voice and circuit-switched analog data calls (up to 56 kbps).

Page 71 Lines Two methods of framing can be used by a 100D module, but the framing chosen must match the framing at the far end: D4 Framing Format The system is factory set for the most common framing format, D4 framing. A D4 frame consists of 24 eight-bit time slots and one framing bit.
Page 72: Line Compensation Settings
Lines Line Compensation Line compensation adjusts for the amount of cable loss in decibels (dBs). It is based on the length of cable between the 100D module and the CSU or between the module and another far-end connection—for example, a line repeater.
Page 73 Lines Clock Synchronization Clock synchronization is an arrangement in which digital facilities operate from a common clock. Whenever digital signals are transmitted over a communications link, the receiving end is synchronized with the transmitting end to receive the digital signals. The system can synchronize itself to the far-end connection by extracting the timing signal from the DS1’s incoming digital stream.

Coverage can be individual or group assigned. These instructions are for both Individual and Group Coverage. Individual Coverage Individual Coverage allows a one-on-one arrangement in which calls from one sender are covered by one or more receivers.
Page 109 Features Assign secondary Individual Coverage for senders whose calls need less frequent coverage—for example, users who provide backup only during peak calling periods. See "Personal Lines" in Chapter 2 of Calls received on personal lines programmed for immediate or delayed ring are System Reference.
Page 110 Features Two types of receivers can be programmed: Multiline telephones. A maximum of eight Group Cover buttons can be programmed for each coverage group. All eight can be programmed on one multiline telephone or the Group Cover buttons can be distributed over up to eight multiline telephones.
Page 111 Features Note: The ringing pattern heard by an outside caller is shorter than the audible ringing heard at an MLX or analog multiline telephone even though the total time is exactly the same. An outside caller hears from one to two rings in addition to the number of rings programmed for the Delayed Ring Interval and Coverage Delay Internal.
Page 112: Group Calling
Features Group Calling Group Calling allows you to group the telephones of people (such as ticketing agents) who all handle the same type of call. Through the Group Calling feature all telephones in the group are assigned to a single extension number that is used by both inside and outside callers to reach the group.
Page 113 Features Planning Form Instructions Review the Employee Communication Survey analysis and determine the number of calling groups needed. Make that number of copies of both sides of Key System Form 6e, Group Calling. Note: Form 6e has two sides. List the extensions (and lines) assigned to the group on the front and specify the options for the group on the back.
Page 114 Features Hunt Type Hunt Type allows you to change the hunting pattern from the factory-set circular type to linear. The system then searches for an available telephone in the order that telephones are assigned to the calling group. If you choose linear hunt, be sure you have listed the extension numbers and names in the “Stations"...
Page 115 Features Message Waiting Receiver Message Waiting Receiver allows you to designate a telephone to receive message-waiting indications for the group. The message receiver for a calling group does not have to be a member of the group. Each calling group can have only one telephone assigned as its message receiver.
Page 116 Features Planning Form Instructions Under the "External Alert for Calls-in-Queue Alarm" on Form 6e: Do one of the following: Check "No" if youdo not want an external alert for Calls-in-Queue Alarm and continue to the "Overflow Coverage" instructions.

Page 120: Call Park Return Time
Features Camp-On Return Time Camp-On Return Time is the number of seconds a caller waits when a person uses the Camp-On feature to complete the transfer of a call to a busy telephone. If the telephone is still busy at the end of the programmed interval, the call returns to the person who transferred the call.
Page 121: Extension Status
Features Extension Status Extension Status allows an operator, a calling group supervisor, or a Call Management System (CMS) supervisor to determine the status of a telephone at a glance. The lights next to the buttons on a DSS or next to Auto Dial buttons programmed with extension numbers indicate the status of the telephone.
Page 122: Station Message Detail Recording
Features Station Message Detail Recording Use these instructions only if connecting Station Message Detail Recording (SMDR). SMDR allows you to keep track of telephone usage. Through this feature detailed call reports are generated that include information about incoming and outgoing calls, such as date and time, the length of the call, the line used, the user’s extension number, the dialed number, and the account code.
Page 123: Inside Dial Tone
Features Inside Dial Tone Two types of inside dial tone are offered, which make it easy to distinguish an inside line from an outside line—system internal dial tone (the factory setting) and outside line dial tone. Some software applications, such as voice messaging systems, or hardware, such as modems, do not recognize the internal dial tone.
Page 124: Allowed Lists
Features Redirect Calls to Unassigned Extension Numbers The factory setting for calls made to unassigned extension numbers by Remote Access users on dial-in tie trunks is that the calls are redirected to the primary operator. You can change the setting so that calls are redirected to another extension number or a calling group Planning Form Instructions Under the "Calls to Unassigned Extensions"...
Page 125: Disallowed Lists
Features Another list of emergency numbers could be designed for telephones that are restricted from local and toll calls. This ensures that telephones restricted from making outside calls can be used in an emergency. Note: If you assign a zero as the first digit for any entry in an Allowed List, any toll restrictions assigned for calls to numbers that can be placed by local or toll operators are removed.
Page 126: Night Service
Features designed the lists, decide which telephones to restrict. You can assign each telephone to one to eight lists. Note: Users cannot dial a number on an Allowed List if it matches a number on a Disallowed List assigned to the telephone. Planning Form Instructions On Key System Form 6h, Disallowed Lists: Write the name of the list in the space next to the list number.
Page 127 Features Any call that comes in to the operator console while Night Service is in effect rings immediately at each available telephone in the group. Calls ring immediately even on lines set for delayed ring or no ring. You can create up to eight Night Service groups, one for each operator. There is no limit to the number of telephones assigned to each group, and each telephone can be assigned to more than one group.
