Assigning Lines/Trunks to Data and Video Stations

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:
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 or 008 OPT module.
All equipment connected to a digital extension jack on an 008 MLX or
408 GS/LS-MLX module.
The factory settings can be changed; however, at least one ICOM button must
be assigned to each data station. To allow a user to make and receive outside
data calls, you must assign an outside trunk to the data station.
To dedicate a specific line to receive outside data calls, assign an outside
line/trunk to a data station, DHG, LAN workstation, or local host computer.
