Planning Form Instructions
Record your decisions for each data station on the Hybrid/PBX Mode Button
Diagram of Data Form 1a or 1b.
1. If you want to assign personal lines to the data station, write Personal Line
and the telephone number (from Form 2c) of the outside line on the
appropriate button. For ISDN terminal adapter data stations, include the
line/trunk number.
2. If you want to assign a pool to the data station, write Pool and the pool's
extension number (from Form 2c) on the appropriate button.
NOTE: NOTE: NOTE:
On modem data stations from which the user does not need to make inside
calls, you can assign only personal lines or pools; when going off-hook, the
user or equipment gets a telephone company line/trunk by automatic Line
Selection.

Assigning Line Buttons in Key Mode

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/Trunk. Used to make and receive outside data calls on a
specific outside line/trunk. An outside line/trunk can be assigned to a line
button on one or more data stations or voice extensions. To dedicate an
outside line/trunk for data calls and have the calls automatically answered
at a data station, do not assign the same outside line/trunk to data stations
and to telephones, because modems answer voice calls as data calls.
For digital data stations, the outside line/trunk can be used to make and receive
outside data calls. For an outgoing call, the user dials the line number
(801-880) to select the line/trunk.
To allow the user at an ISDN terminal adapter data station access to the digital
network for making and receiving calls to outside digital data stations, assign PRI
facilities with digital data service such as ACCUNET Switched Digital Service and
Software Defined Network (SDN), NI-1 BRI, or T1 Switched 56 facilities to ISDN
terminal adapter data stations. If these facilities are not available, the ISDN
terminal adapter data station user can make calls over the regular analog
telephone network only by using a digital-to-analog modem pool, described in
application note, MERLIN LEGEND Communications System Modem Pooling.
NOTE: NOTE: NOTE:
PRI and NI-1 BRI facilities are also used for analog data and voice calls and
can be assigned to telephones to allow the voice user to make and receive
voice calls using these types of facilities.
