Assigning Lines/Trunks to Data and Video Stations
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 the
application note, MERLIN LEGEND Communications System Modem Pooling .
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.
The following line button assignments are factory-set for Key mode and are
prerecorded on the Button Diagram on Data Forms 1a and 1b. Two Intercom Ring
(ICOM Ring) buttons are assigned to the following:
Data equipment connected to an 012 (T/R), 016 (T/R), or 008 OPT module;
or, in Release 7.0 and later systems, to a port programmed for tip/ring
operation on a 412 LS-ID-ETR or 016 ETR module.
All equipment connected to a digital extension jack on an 008 MLX, 408
GS/LS-MLX, 408 GS/LS-ID-MLX, or 016 MLX (Release 7.0 and later)
module.
