Planning
Assigning Lines in Key
Mode
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. Use the instructions on pools in Chapter 3 of PBX System
Planning.
If the system uses Automatic Route Selection, follow the instructions on ARS in
Chapter 4 of PBX System Planning to specify routes for outgoing data calls.
To restrict non-data users from dial access to data trunk pools, use the "Pool
Dial-Out Code" instructions in this chapter.
Planning Form Instructions
Locate System Form 2c, System Numbering—Trunk/Line Jacks and PBX
System Form 3b, Outside Trunks—Pools.
Record your decisions for each data station on the Hybrid/PBX Mode "Button
Diagram" or Data Form 2a or 2b.
1. If you want to assign personal lines to the data station, write "Personal
Line" and the telephone number (form System Form 2c) of the outside line
on the appropriate button. For digital stations, include the trunk number.
2. If you want to assign a pool to the data station, write "Pool" and the pool's
extension number (from system Form 3b) on the appropriate button.
Note: On analog data stations where the user does not need to make internal
calls, you can assign only personal lines or pools; the user will get a CO line by
automatic line selection when going off-hook. This will automatically get central
office dial tone.
There are two kinds of line buttons you can assign to data stations used to make
and receive data calls:
Intercom Ring — used to make and receive inside data calls only.
Outside Line — used to make and receive outside data calls on a specific
outside trunk. An outside line can be assigned to a line button on one or
more data or voice stations. To dedicate an outside line for data calls and
have the calls automatically answered at a data station, do not assign the
same outside line to data stations and to telephones because modems
answer voice calls as data calls.
For digital stations, the outside line can be used to make and receive outside
data calls. For an outgoing call, dial the line number (801-880) to select the
Iine.
