Assigning Lines/Trunks to Data and Video Stations
On analog voice-and modem data stations, a personal line can be used to
receive incoming calls. A personal line can be used for outgoing calls by
selecting the line button on the analog multiline telephone, dialing, and
then activating the modem connected through a GPA.
On ISDN terminal adapter data stations, a personal line can be used to
make and receive outside data calls. To select the line/trunk for an outgoing
call, the caller dials the line/trunk number (801–880). 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,
NI-1 BRI, or T1 Switched 56 (including T1-Tie lines using Switched 56
service) facilities as personal lines.
Pool. Used when you want the voice and data station to make and receive
outside data calls on a specific trunk pool (for example, a pool with PRI
facilities) without dialing a dial-out code. The Pool button is used to make
and receive only outside calls. Automatic Line Selection should be set to
the Pool button in order to place calls on it.
NOTES:
The following line button assignments are factory set for Hybrid/PBX mode and
are prerecorded on the Button Diagram on Data Forms 1a and 1b:
One System Access Originate Only (SA Orig Only) button and two System
Access Ring (SA Ring) buttons are assigned to all data equipment
connected to a tip/ring port on 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.
One System Access Originate Only (SA Orig Only) button, one System
Access Ring (SA Ring) button, and a System Access Voice (SA Voice)
button are assigned to all data 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 systems) module. Remove the SA Voice button (see
Form 5c, page 1).
Do not assign System Access Voice (SA Voice) buttons to data
communications equipment.
You must use PRI facilities with a digital data service such as ACCUNET
Switched Digital Service, a Software Defined Network (SDN), T1
Switched 56 facilities, or NI-1 BRI facilities for digital data calls.
T1 facilities that are not using Switched 56 service can be used for
modem data and analog voice calls and can be assigned to telephones
to allow the voice user to make and receive voice calls using these types
of facilities.
