Page 48: Station Jacks
Planning Station Jacks To plan how data equipment connects to station jacks on the control unit: Review System Form 2a, on which you entered codes (A for analog, D for digital, and B for basic telephone) and find the telephone type and the user, location, or function for each data station to be connected.
Page 49 Planning See System Planning (Key or PBX) for Planning Form Instructions instructions for reassigning station extension numbers. (The same Record the station jack assignments for analog data stations on System instructions are used for data as for Form 2a, System Numbering—Station Jacks: voice stations.) 1.
Page 50 Planning Assign each data module used for access to a host computer to a digital station jack on a 008 MLX module and each modem to a basic telephone station jack on a 012 or a 008 OPT module. Users access the computer by placing a data call to the extension number for either a data module or modem assigned for communications with the local host computer.
Page 51 Planning Planning Form Instructions Record the station jack asignments for access to a workstation on a LAN on System Form 2a, System Numbering—Station Jacks: 1. In the "Jack Type" column, make sure there is a "D" next to the number for each digital station jack you plan to use to connect an ISDN 7500B Data Module.
Page 52: Modem Pools
Planning Modem Pools See Chapter 1 for information about A modem pool consists of one or more pairs of data modules and modems. connections. Modem pools convert digital data signals to analog data signals or convert analog data signals to digital signals and are called “conversion resources.” A modem pool allows data communications between digital data stations and analog data stations.
Page 53: Modem Pools On Dedicated Outside Lines
Planning For a modem pool using system lines, assign one digital station jack for each data module and one basic station jack for each modem. Planning Form Instructions Record the station jack assignments for modem pool equipment on System Form 2a, System Numbering—Station Jacks: 1.

Pool When modems and ISDN 7500B Data Modules are connected to station jacks, an extension number is automatically assigned to each.
Page 56: Assigning Lines To Data Stations
Planning Assigning Lines to Data Stations Decide on the types of line buttons that are assigned to the data terminal portion of each digital or analog data station and to each modem and ISDN 7500B Data Module. This includes analog data stations connected through MFMs to MLX telephones digital data stations that include a telephone analog data stations digital data stations...
Page 57 Planning Planning Form Instructions Continued Record the information on the appropriate Data Form (2a or 2b) for each data station and for each modem and ISDN 7500B Data Module included in a modem pool or used to communicate with a local host computer or with a workstation on a LAN: 1.
Page 58 Planning On digital stations, the personal line can be used to make and receive outside data calls. For an outgoing call, dial the trunk number (801-880) to select the trunk. To allow the user at a digital station access to the digital network for making and receiving calls to outside digital stations, assign ISDN-PRI trunks as personal lines.
Page 59 Planning To dedicate a specific line or pool to receive outside data calls, assign a personal line or pool to a data station, modem pool, or data hunt group that is assigned to a modem pool. To dedicate specific trunks for use in data communications only (such as Primary Rate Interface channels or other special data lines), consider grouping those trunks in a pool.
Page 60 Planning To allow the user at a digital station access to the digital network for making and receiving calls to outside digital stations, assign ISDN-PRI lines to digital stations. If ISDN-PRI lines (with Accunet Switched Digital Data Services) are not available, the digital data station user can make calls over the regular analog telephone network only by using a digital-to-analog modem pool.
Page 61: Assigning Features To Data Stations
Planning Assigning Features to Data Stations This section describes how to assign features to each digital or analog data station and to each modem and ISDN 7500B Data Module pair. This includes analog data stations connected to an MLX telephone using an MFM or digital data stations that include a telephone and analog and digital data stations (data stations that do not include a telephone).
Page 62 Planning Use these instructions only if the system is operating in the Hybrid/PBX Pool Dial-Out Code mode. When a data station is first connected, the user can access any trunk pool by dialing the dial-out code assigned to the pool. However, you can restrict data stations from using one or more trunk pools.
Page 63 Planning See System Planning (Key or PBX), Note: If you assign restrictions to a modem pool, assign the same restriction to Chapter 4, for instructions on Allowed all members of the pool. If these restrictions are too limited, you can use the List and Disallowed List.
Page 64 Planning For modems assigned to a digital-to-analog modem pool, set the ringing option Ringing Options for the line buttons to "no ring." This prevents the modem from answering calls placed in error to the wrong side of the modem pool (the side away from the data hunt group or extension assigned to the modem in an analog-to-digital modem pool or to the ISDN 7500B Data Module in a digital-to-analog modem pool).
Page 65 Planning To avoid giving the telephone number of a remote computer to modem pool System Speed Dial Codes users, assign a System Speed Dial code to the telephone number. Users can dial this 3-digit code to place data calls to the remote computer. For data calls, the telephone number programmed for a Speed Dial code must include the access code (the pool dial-out code or the ARS dial-out code).
Page 66: Data Hunt Groups
Planning Data Hunt Groups The Data Hunt Group feature is used to designate a group of either modems or ISDN 7500B Data Modules (not both) to receive calls in a modem pool or to communicate with a local host computer or workstation on a LAN. All modems or data modules in a data hunt group are assigned to a single extension number that is used both by inside and outside callers to reach the group.
