Preparation Several actions must be completed before the system is installed: ■ Review ■ the system’s hardware, features, and operation. Arrange for the location of the control unit. ■ Survey ■ Find telephone users on their needs. or create a floor plan. System Components To tailor the system for your company, you must know the number and types of telephones, outside lines, and adjuncts that were ordered. Review the AT&T Equipment List provided by your AT&T representative or authorized dealer.
Preparation Figure 1-1 System Components 1-2 System Components
Preparation 1. Control Unit The backbone of the system, consisting of the basic and expansion carriers, power supply module, processor module, and line and station modules. The control unit connects telephone company lines with stations such as telephones and adjuncts. 2. Line/Trunk and Station Modules. The components that connect telephone company lines and terminal equipment such as telephones, external alerts, and fax machines via jacks to the control unit. 3. Basic Carrier.
Preparation 13. Off-Premises Telephone (OPT). A single-line, touch-tone or rotary, industrystandard telephone located in a different building from the control unit. 14. External Alert. An alerting device such as bells, chimes, and strobe lights that connect to a jack on a012 basic telephone module or a 008 OPT module, or to an MFM or Supplemental Alert Adapter (SAA). 15. Digital Data Terminal.
Preparation Location of the Control Unit Before installation, choose a room, closet, or other area where the system control unit can be mounted on the wall. The area must meet the environmental requirements in Table 1-1.
Preparation Table 1-1 Continued Cautions The AC outlet for control unit should not be switch controlled. ■ Plugging the control unit into an outlet that can be turned on and off by a switch can cause accidental disconnection of the system. ■ ■ The AC outlet must be properly grounded via an AC receptacle for a 3-prong plug. Do not install the control unit outdoors. ■ Do not place the control unit near extreme heat (furnaces, heaters, attics, or direct sunlight).
Preparation Telephone User Survey The features and calling privileges you assign to each employee’s telephone ensure that employees get the most benefit from the system. If you were not involved in the planning and decision-making for the system, find out from your management and your AT&T representative or authorized dealer what telecommunications needs were identified.
Preparation Name Room Extension Name of work group (Sales, Customer Service) Please answer each question below. 1. Do you regularly use any of the following outside lines? (Check any that apply) ❑ ❑ ❑ ❑ 2. WATS FX (foreign exchange) Tie None of the above or don’t know Are your phone calls covered when you’re away from your desk? ❑ No ❑ Yes 3.

Preparation Use the information in Table 1-3 to interpret and analyze the results of the Employee Communication Survey. Table 1-3 Employee Communication Survey — Sample Analysis 1. Types of lines used Indicates toll calling habits. In most cases, assigning a button for each line is not necessary. 2.
Preparation Floor Plan Use a floor plan to make planning more manageable and to ensure that the correct telephone equipment is assigned to each employee. If your organization is moving to a new location, a floor plan may already be prepared and you may be able to get a copy of it from your management. Create a floor plan in two phases: 1. Indicate the location and type of telephones, adjuncts (fax, answering machines, etc.), and data terminals. 2.
Preparation Figure 1-3 Floor Plan As shown in Figure 1-3, the floor plan does not need to be elaborate or to scale. The telephone symbol should be large enough to accommodate the size of telephone and the assigned number, and if you find it helpful, the name of the employee. Keep the floor plan. You will refer to it during planning and complete it (by filling in extension numbers) when you get to “System Numbering” in Chapter 2.
Control Unit Planning the control unit consists of deciding how to place the modules, setting the system operating conditions, and numbering the system. Modules Certain modules are required for every system: ■ Processor module contains the memory that controls the system software and features. It also contains the software and firmware that support built-in system diagnostics and the built-in data modem used for remote maintenance and system programming.

Control Unit The lines and stations that can be connected to the jack types shown in Figure 2-1 are described below: 1. A DS1 line jack connects a Digital Signal 1 (DS1) facility provided by the telephone company. The DS1 facility can be set for either T1 or Integrated Services Digital Network Primary Rate Interface (ISDN-PRI) operation. The DS1 facility programmed for T1 operation supplies 24-channel emulation of any combination of ground-start (GS), loop-start (LS), and tie trunks.

Control Unit Station capacity is the number of stations that can be connected to the control unit, and it equals the number of physical jacks on the line and station modules. See “System Numbering” in this chapter for detailed information.
Control Unit ■ Group all 100D and 400EM modules together according to type, whenever possible, to save time in system programming. Each physical jack on the control unit is numbered sequentially from left to right and bottom to top: ■ Station jacks are numbered from 1 to 144. ■ Line jacks are numbered from 1 to 80. This sequence of numbers is called the "logical ID.
Control Unit Figure 2-2 Sample Control Unit Diagram Modules 2 - 7
Control Unit System Operating Conditions Use the “Control Unit Diagram” on Key System Form 1 as a reference and mark the “System Operating Condtions” section of that form.
Control Unit Mode of Operation See System Reference for more information on modes. Your system is registered with the FCC to operate as a Key system. However, you can program the system to operate in any of three modes: ■ Hybrid/PBX ■ Key (the factory setting) ■ Behind Switch The mode of operation determines ■ how outside lines are provided to users ■ the types of operator consoles allowed ■ the features available and how they work.
Control Unit In the Behind Switch mode single-line telephones can be programmed to select only the prime line (the user cannot make inside calls or use system features) or to select the intercom button followed by the prime line or outside line (the user can place and receive inside calls and use system features). Planning Form Instructions Under the "Set System Mode" heading on Form 1: 1. Check "Key" if you want your system to operate in the Key mode. 2.
Control Unit System Numbering System numbering is the process of assigning extension numbers to stations (telephones and adjuncts), calling groups, paging groups, Park zones, and Remote Access. The instructions is this chapter deal only with assigning extension numbers to stations. Number the stations in two stages: Stage One. Decide in what order to connect the telephones and other equipment to the control unit.
Control Unit Station Jack Connections Planning station jack connections consists of identifying the jack types and matching the telephones and other equipment to the jacks that support them.
Control Unit Planning Form Instructions In the "Jack Type" column of Form 2a, indicate the type of each station jack next to its logical ID. Jacks for Primary Operator Position 1 . Check "A" if the jack is Analog, "D" if Digital, or "B" if Basic telephone. 2 . The system reserves 12 logical IDs for the 008 OPT module even though only 8 are used. Cross off the last 4 logical IDs (they cannot be used).
Control Unit Table 2-3 Maximum Number of Operator Positions Telephone Type Processor Module Size MLX-20L MLX-28D Small 6 MLX-20L MLX-28D Large 8 Analog multiline telephones Small or Large 8 Maximum Positions Assign DLCs to only the first and fifth station jacks on a digital or analog module. This includes DLC positions used for calling group supervisors and for the optional Call Management System (CMS). The CMS equipment is connected to analog station jacks that are assigned as DLC positions.
Control Unit ■ Simultaneous Voice and Data. A user whose telephone has this feature can use the telephone and a data terminal at the same time. (MLX telephones have this feature without requiring a second station jack.) An analog multiline telephone with either one of these features requires two consecutive analog station jacks on the control unit. The jacks are an oddnumbered analog station jack and the next higher (even-numbered) analog station jack.
Control Unit Planning Form Instructions Use the Floor Plan and AT&T Equipment List to verify that you have located all remaining MLX telephones and adjuncts to them. On Form 2a, mark the station jack assignments for the remaining MLX telephones: 1. In the "Jack Type" column, make sure there is a "D" checked next to the logical ID for each digital station jack. 2. In the "Person, Location, or Function" column, identify each MLX telephone by person, location, or function.
Control Unit Jacks for Tip/Ring Equipment and Applications See System Reference for more information on applications. Use these instructions only if the system includes 012 or 008 OPT modules. Assign the basic telephone jacks on the 012 or 008 OPT modules to any tip/ring equipment such as single-line telephones, fax machines, or answering machines. Tip/ring equipment connects directly to an outside line and works on a single pair of wires.
Control Unit System Renumbering Use these instructions to decide whether to keep the factory-set extension numbers or to change them to numbers taylored to your company — for example, extension numbers that match room numbers. The system offers three numbering plans, as shown on Form 2a, System Numbering — Station Jacks. Each plan allows you to renumber all or selected extensions.

Lines Planning Form Instructions Review the module listed on the "Contrrol Unit Diagram" on Form 1. On Key System Form 2c, System Numbering — Line Jacks: 1. Write the type of each line jack in the control unit in the "Jack Type" column. Use the codes shown in Table 3-2. For systems that include the 100D module: 2. 3. If the module is used only to emulate lines: ■ Fill in the jack type codes for those lines (T1-GS, T1-LS, or T1-Tie).
Lines Jacks for Outside Lines Identify the specific outside lines you want to connect to each loop-start and ground-start/loop-start line jack. Connect outside lines to a continuous sequence of line jacks on the control unit, beginning with the first line jack (logical ID 1). Use line jacks at the beginning of the sequence for basic loopstart lines. Use jacks later in the sequence for special-purpose lines such as WATS or FX (foreign exchange).

Lines Jacks for Auxiliary Equipment Use these instructions only if the system has auxiliary equipment such as Music-on-Hold. Auxiliary equipment can be connected only on loop-start (LS) or groundstart/ loop-start (GS/LS) jack types. You cannot use a line jack on a 100D or 400EM module for auxiliary equipment, If you plan to use Music-on-Hold, designate a line jack for the music source such as a radio, tape player. stereo system, or Magic on Hold equipment.
Lines Line Options Choose from the following options for the outside lines connected to the system and record your decisions on Key System Form 2c, System Numbering — Line Jacks: ■ Loop-Start Disconnect Reliability ■ Rotary Dial Lines ■ Toll Prefix Dialing Requirements (Toll Type) ■ Hold Disconnect If the system includes any or all of the following additional line options, mark the Outside Lines forms (3a, 3c, and 3D): ■ Remote Access ■ DS1 Facility ■ Tie Trunks Loop-start Disconnect Reliab
Lines Rotary Dial Lines The system is factory set to generate touch-tone signals when users dial outside calls. Identify any rotary dial lines that are connected to the system so that rotary dial signals can be used for these lines. Note: Touch-tone single-line telephone users cannot make calls using lines programmed for rotaary operation. Check with your local or long-distance telephone company to determine which, if any, lines connected to the system are rotary dial lines.
Lines Planning Form Instructions In the "Short Hold Disconnect Interval" column of Form 2c, check "Yes" next to any lines that you want to change from the long (450mn) interval to the short (50 ms) interval. See "Loop-Start Disconnect Reliability” earlier in this section. Note: Be sure you have checked "No" for "Loop-Start Reliable Disconnect" if your local telephone company uses a Short Hold Disconnect interval. Remote Access Use these instructions only if remote users need access to the system.
Lines You can provide security for the system by requiring that people using Remote Access dial a password or barrier code to call into the system. When barrier codes are required, the caller dials a 4-digit number after the Remote Access special dial tone and then hears the system dial tone. CAUTION Under applicable tariffs, the customer is responsible for any charges incurred through the remote use of system facilities.
Lines Planning Form Instructions—Continued 2. Under the heading "Automatic Callback" at the top of Form 3a: ■ ■ Check "Disable" if you do not want remote callers to use this feature. Check "Enable" to allow this feature to remote callers. 3. Under the heading "Barrier Codes for Tie Trunks": ■ Check "Yes" if you plan to assign barrier codes to these lines. ■ Check "No" if no barrier codes are planned. 4. For "Barrier Codes for Non-Tie Lines": ■ Check "Yes" if you plan to assign barrier codes.
Lines 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. CAUTION Under applicable tariffs, the customer is responsible for any charges incurred through the remote use of system facilities. Precautions should be taken to prevent unauthorized use of the system’s outside lines by remote callers, also called toll fraud.
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. The 100D module is the interface that allows the connection of DS1 facilities to the system.
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.
Lines Table 3-3 Continued T1* ISDN-PRI x x Service Description Software Defined Network (SDN) A virtual private networking service for voice and circuit-switched analog data calls (up to 56 kbps). SDN lets businesses use portions of the AT&T Switched Network in concert with their dedicated private line networks. However, the system does not support "uniform dialing plan,” which is necessary for complete integration with SDN.
Lines Planning Form Instructions On Key System Form 2c, System Numbering — Line Jacks, in the "Jack Type" column: 1. Find all lines listed as "PRI" ■ See “Signaling Mode” in this chapter. Write the kinds of service connected to each channel in the "Line Type" column. Note: You cannot use the 24th channel for services. ■ 2 . Write "unequipped" in the "Line Type" column for any channel not used at this time.
Lines Two methods of framing can be used by a 100D module, but the framing chosen must match the framing at the far end: Line Code ■ 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. To synchronize the signals, the receiving equipment uses the framing information to identify the start of each frame and to identify which frames contain signaling information.
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. The factory setting is a value of 1, which allows a maximum loss of 0.6 dB. The other possible settings are shown in Table 3-4 (based on 22-gauge cable). Table 3-4 Line Compensation Settings Setting dB Loss Cable Feet 1* -0.6 0–133 2 -1.
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.
Lines Planning Form Instructions—Continued 10. If installing more than one 100D Module, decide which Module, if any, provides the primary synchronization. ■ If Module 1 provides clock synchronization, check "Primary" in the first column (the factory setting). ■ If Module 2 (or Module 3) provides clock snychronization, check "Primary" in the column that describes that 100D module. ■ If the synchronization source is other than through a 100D module check "None".
Lines Planning Form Instructions—Continued 13. Channel Service Unit Setting for T1 Emulation Under the "Signaling Mode" heading of Form 3c, in all the columns that describe T1 Modules: ■ Check "RBS" to retain the factory setting of robbed-bit signaling. ■ Check "CCS" to change the factory setting to common-channel signaling. Use these instructions only if the 100D module type of service is T1 and outside lines are to be emulated.
Lines Telephone Number To allow the system to route calls to the correct destination, you can assign a telephone number consisting of up to 12 digits. The factory setting is no telephone number is assigned. If you assign a telephone number to a channel, it must match the number that is dialed by the outside caller and sent to the system by the network. The numbers sent by the network are furnished by the ISDN-PRI service provider.
Lines Test Telephone Number For each 100D module with an ISDN-PRI service type, you can assign a test telephone number that is used for maintenance by the service provider. See “B-Channel Groups" later in this chapter. The factory setting is that a test telephone number is not assigned. The number you assign must be the same number as that furnished by the ISDN-PRI service provider.
Lines Table 3-5 Timers and Counters Name Description Factory Setting Allowable Threshold T200 Timer Times the delay in link-layer acknowledgement of a message sent over a D channel from the system to the network. 1 second 100-3000 ms T203 Timer Times the interval of each exchange of messages on the D channel between the system and the network.
Lines Planning Form Instructions Under the "Timers and Counters" heading on Form 3c: 1. To change the factory setting for any timer or counter, write the new threshold in the "Change To" column. 2 . To keep the factory setting, leave the "Change To" column blank. B-Channel Groups To make the most effective use of ISDN-PRI service, assign B channels (channels 1 through 23) to groups.

Lines Tie Trunks Use these instructions only if the system has tie trunks, including tie trunks emulated through a DS1 facility. Tie trunks are private lines between your system and the central office or between two communications systems—for example, between this system and another system of the same type, or this system and a System 25 or a System 75. Tie trunks must be configured to match central office requirements or the configuration of the system to which they tie.
Lines Signaling Type The choices for signaling type (also called seizure type) are wink, delay, immediate, and automatic. Of the four types, wink, delay, and immediate are similar in that they allow users to call people in the other system by dialing their extensions. With the automatic type, no dialing is needed: users call an operator who then transfers the call to the proper person.
Lines Dial Mode Choose an incoming (inmode) and outgoing (outmode) dial mode, either touchtone or rotary. For two-way tie trunks, you must choose a dial mode for incoming and outgoing. The system is factory set for rotary for both directions. Note: If you have checked “Incoming’ for a tie trunk’s direction and “Immediate” for its signaling type, you cannot have touch-tone mode. Planning Form Instructions On Form 3d: 1.
Lines Line Assignment Follow the instructions in the Data Guide to assign lines to data stations. Use these instructions to assign lines to telephones and direct-line consoles. There are five different forms for recording line assignments. Prepare one copy of the appropriate form for each station.
Lines Planning Form Instructions 4. Identify the equipment at each station (Refer to the Floor Plan). ■ Check the box that describes the ltelephone, console module, or type of tip/ring equipment. ■ Check the box under "Adjuncts" that describes the adjuncts at the station. Note: Checking the "Data Terminal" box is informational only, See the Data Guide. Telephones See Chapter 4 of System Reference for additional information on modes and line assignments.
Lines Behind Switch Mode Only Prime Line button - used to access the host system’s pool of outside lines. To call another person connected to the host system, the user dials the host system extension number assigned to that person. To access outside lines, the user dials a dial-out code (usually a 9), and the host system selects an available outside line from its pool.
Lines Key Mode Behind Switch Mode Up to 8 Personal Line buttons are assigned beginning at button 3 One Prime Line button is assigned to button 3. Figure 3-4 Factory-Set Assignment, Analog Multiline Telephones Although equipment such as single-line telephones, answering machines, and fax machines do not have buttons, the system treats them as multiline telephones with 34 buttons. In both the Key and Behind Switch modes, the system assigns no outside lines to this type of equipment.
Lines Key Mode For multiline telephone users: You can assign a combination of up to 10 Intercom Voice, Intercom Ring, or Intercom Originate Only buttons to each station (excluding operator positions). Assign additional Intercom Ring, Intercom Voice, or an Intercom Originate Only button for people who frequently receive or make transferred calls.
Lines For single-line telephone users, answering machines, fax machines, or any other device connected to a 012 or 008 OPT module or an MFM consider assigning ■ additional prime lines ■ any outside lines connected directly to the control unit, including specialpurpose lines Single-line telephones can be programmed to select only the prime line (the user cannot make inside calls or use system features) or to select the intercom button followed by the prime line or outside line (the user can place and rec
Lines Direct-Line Consoles Use these instructions only if the system has one or more direct-line consoles. See the Direct-Line Consoles Operator’s Guides for more on DLCs. The line buttons automatically assigned to DLCs are different from those on other telephones. In typical systems, DLC operators are responsible for handling all incoming calls.
Lines Figure 3-6 Analog Multiline DLC The system assigns lines to buttons on DLCs in the order in which the lines are connected to the control unit. You can change the factory-set assignments by removing, adding, or changing the order in which lines are assigned to buttons for each DLC operator.
Lines Planning Form Instructions Complete the "Button Diagram" on each copy on the back of Form 5a and the front of Form 5b. 3-44 Line Assignment 1. Write the telephone number of the line you want to assign in the space on the "Button Diagram". For future reference, record each line's number. (Refer to Form 2c). 2. Assign Alarm, Night Service, or Send/Remove Message buttons by labeling the appropriate button "Alarm", "Nite Serv.", or "Send/Rem Msg.". 3.
Features The MERLIN LEGEND Communications System offers these optional features: ■ Telephone Features — assigned to individual telephones, consoles, or adjuncts Operator Features — assigned to all operator consoles Group Assigned Features — apply to functional groups of users (such as separate departments) ■ System Features — affect all or most of the users Telephone Features Instructions for assigning these features to the individual telephones used by both system operators and general users are: See
Features ■ Key System Form 4c, Tip/Ring Equipment ■ Key System Form 5a, Direct-Line Console (DLC) — Analog ■ Key System Form 5b, Direct-Line Console (DLC) — Digital/lSDN (the front for the console and the back for an adjunct connected using a Multi-Function Module) Call Restrictions When the system is set up, users can place local and toll calls from all telephones.
Features Microphone Operation The microphone on MLX telephones and analog multiline telephones allows users to have conversations through a speakerphone without lifting the handset. You can disable the microphone on MLX telephones (but not on analog multiline telephones) in areas in which use of the speakerphone is disruptive. Planning Form Instructions Under the "Microphone Operation" heading on Forms 4b and 5b: 1. Check "Enable" to keep factory setting. 2. Check "Disable" to prevent speakerphone use.
Features Fax Message Waiting Receiver and Threshold Use these instructions only if the system has fax machines connected directly to the control unit via a 008 OPT or 012 module or connected to an MLX telephone using a Multi-Function Module (MFM). These instructions are not applicable to fax machines connected to an analog multiline telephone using a General Purpose Adaptor (GPA).
Features Operator Features Operator features apply only to direct-line consoles (DLCs) and any Direct Station Selectors (DSSs) connected to them. Operator features you assign apply to all DLCs in the system. Mark the operator feature assignments on Key System Form 6a, Optional Operator Features. Direct-Line Console Use these instructions only if the system has one or more DLCs.
Features Planning Form Instructions Under the "DLC Automatic Hold" heading on Form 6a, do one of the following: ■ Check "Disable" to keep the factory setting. ■ Check "Enable" to enable the feature. Direct Station Selector Page Buttons Use these instructions only if the system has Direct Station SeIectors (DSSs) connected to digital/lSDN (MLX) operator consoles. Operators use the buttons on a DSS for one-touch automatic dialing (Auto Dial) of station extension numbers.
Features In addition to providing one-touch dialing of telephones, you can set the Page buttons to include one-touch feature use. For example, one Page button’s range might be set to include the extension numbers resewed for Call Park codes or Group Calling extensions. (See the “Call Park Codes” instructions that follow.) Use the information from Key System Form 2a, System Numbering — Station Jacks, to assign the range of stations for each Page button.
Features Group Assigned Features The system offers four features that facilitate the call-handling responsibilities of groups of users. The features and the corresponding Key System Forms used to plan them are ■ Call Pickup Groups, Form 6b ■ Group Paging, Form 6C ■ Group Call Coverage, Form 6d ■ See Chapter 1 for information about analyzing Employee Communication Survey forms.
Features Planning Form Instructions — Continued 2. Write the name of a group, such as Customer Service, in the "Group ID" space. (Refer to the Survey Analysis). 3. Write the extension number for each group member in the "Ext. No." column. (Refer to Form 2a). 4. Write each group members name or location in the "Person or Location" column. (Refer to Form 2a). Group Paging Group Paging allows users to make voice announcements that are heard by a particular group of employees or by everyone.
Features Coverage See "Coverage" in Chapter 2 of System Reference for more information. Individual Coverage Coverage allows calls to users (called senders) to be covered by one or more telephones (called receivers). Coverage can be individual or group assigned. These instructions are for both Individual and Group Coverage. Individual Coverage allows a one-on-one arrangement in which calls from one sender are covered by one or more receivers.
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 System Reference. Calls received on personal lines programmed for immediate or delayed ring are eligible for coverage. Calls on personal lines programmed for no ring are not covered. If a principal user is assigned, all calls are sent to the principal’s receivers.
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. A single receiver can have more than one Group Cover button for the same coverage group; however, each programmed button is counted in the eight Group Cover button maximum for the group.
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.
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. The individual extension numbers of the telephones are still used by callers who need to reach a specific member of the calling group.
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. On the front of F o r m 6 e : 1. Write the group number in the "Group No." space. Start with 1 and number sequentially. 2.
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" area on the front of Form 6e in the order that you want the group searched.
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. The same telephone can be assigned as the message receiver for more than one calling group.
Features Planning Form Instructions Under the "External Alert for Calls-in-Queue Alarm" on Form 6e: 1. 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. ■ Check the second box to designate an external alert. Write the extension number for the alert in the space provided. (Refer to Form 2b).
Features Group Type Group Type determines whether or not the system automatically logs in members of a calling group following a power failure. The factory setting is no automatic system Iogin (auto Iogout). You can change the factory setting to one of the following: ■ Auto Login.
Features System Features See System Reference for more information on system features. System features affect all users and all or most of the telephones. Record your decisions about them on Key System Form 6f, System Features.
Features Planning Form Instructions Under the "One-Touch Call Handling: heading in the section of Form 6f, do one of the follwoing: ■ ■ Transfer Audible "Transfer Options" Check "One-Touch Transfer" to keep the factory setting. ■ To keep the factory set automatic completion of transfers, check that box. ■ To change the factory setting to manual completion, sheck that box. Check the "One-Touch Hold" if you do not want to keep the One-Touch Transfer feature.
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. You can change the factory-set 90-second interval to 30-300 seconds.
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.
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.
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. In this case, change the system so that inside dial tone is the same as the outside dial tone to allow recognition by a third-party system.
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" heading on Form 6f, do one of the following: ■ Check "Primary Operator" to keep the factory setting.
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. Planning Form Instructions On Key System Form 6g, Allowed Lists: See "Remote Access” in Chapter 3.
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: 1. Write the name of the list in the space next to the list number. 2. Write the disallowed area codes and/or exchanges in the column (a maximum of 10 entries per list).
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.
Features Planning Form Instructions On Key System Form 7b, Night Service — Outward Restriction: 1. Write the password in the "Password" space. The password must be four digits and can include the numbers from 0 to 9 in any combination. Note: To keep the password private, do not fill in the blank. 2. Write the numbers to be included in the list, under "Telephone No." in the "Emergency Allowed List" section. To exclude people from the password requirement, complete the "Exclusion List" section.
Features Lines Line labels identify the line being used or the department being called. For example, when a call comes in on one of the incoming lines, a number, such as 5559876, or the name of the department to which it belongs, such as Sales, is displayed. Used with the AT&T lNFO2 automatic number identification (ANI) service, the labels also identify the number of the caller.
Features Planning Form Instructions On Key System Form8c, Label Form — Posted Message: 1. To add posted messages, write each new message next to its message number (11 through 20) in the "Label" column. 2 . To change existing messages, cross out the message and write the new message in the "Revised Standard Message" column. System Directory/ System Speed Dial Users may dial certain numbers frequently, such as the numbers of clients, suppliers, or branch offices.
Modifications To modify the system: ■ Decide what you want to change and identify the programming needed. ■ Complete (or revise) the appropriate Key System Planning Forms. ■ Program the modification using Chapter 3 of System Programming.
Modifications Adding to the System Adding to the system is defined as increasing its capacity or capability. This increase may mean adding more or different kinds of lines, connecting auxiliary equipment, or installing more stations (telephones, consoles or tip/ring equipment). Step 1 Determine the specific type of line, auxiliary equipment, or station to be added. Use Table 5-1 to determine the type of line and/or station module needed to support what you plan to add.
