5 Data Communications
Assigning Lines/Trunks to Data and Video Stations
In Release 4.2 and later systems, these local exchange carrier services are
also available:
NI-1 BRI. Basic Rate Interface (BRI) is a protocol within the ISDN standard
that provides digital voice, data, and video connectivity. NI-1 BRI facilities
connect to a jack on the 800 NI-BRI module, with each facility providing two
B-channels per jack (total of 16 NI-1 BRI channels per 800 NI-BRI module).
BRI facilities provide high-speed data rates of up to 64-kbps clear
(unrestricted) circuit-switched data calls per B-channel (128-kbps total for
2B Data).
To assign lines/trunks to data stations, you decide on the types of line buttons that
are assigned to the data communications equipment at each data station. The
data stations are:
Analog voice and modem data stations and MLX voice and modem data
stations
MLX voice and ISDN terminal adapter data stations including telephones
Modem data-only stations
ISDN terminal adapter data-only stations
Digital data/video stations
The system treats each data station, except for the analog voice and modem data
stations, as an extension with a 34-button telephone.
When you choose the mode of operation (Key, Behind Switch, or Hybrid/PBX),
Intercom (ICOM) or System Access (SA) buttons are assigned automatically to
every extension connected to the control unit. However, you can customize the
system by changing the factory-set assignments and reassigning line buttons.
The number and types of buttons assigned depends on the mode chosen and the
type of extension jack you are using.
For detailed information and telephone programming requirements for
lines/trunks, see the Equipment and Operations Reference .
NOTE: NOTE: NOTE:
Trunks cannot be independently assigned to analog voice and modem data
stations. The line/trunk assignment for the telephone also includes the
modem extension; therefore, these instructions are not used for these types
of data stations.
