System Description
This section provides an overview of the system features and equipment used
to meet the needs of this office. Following this overview, equipment, covering
calls, and restrictions on outgoing calls are described in more detail.
■
Lines/Trunks. One 408 GS/LS module to handle the loudspeaker paging
system and provide a power-failure transfer (PFT) telephone. Three 800
NI-BRI (Release 4.0 and later only) modules supply outside line/trunks to
the system. Two modules are fully equipped, with eight NI-1 BRI (National
Integrated Services Digital Network 1 Basic Rate Interface) facilities on
each module, supplying a total of 32 virtual “lines” (B-channels). The third
800 NI-BRI module currently connects three facilities that provide six
additional B-channels. (For more information about NI-1 BRI access
arrangement and the 800 NI-BRI module, see Chapter 3, “
System
Components.”

■
Extension Modules. One 016 basic telephone module (Release 4.0 and
later only) to handle the modems, single-line telephones, analog fax
machines, and applications. Six 008 MLX modules serve MLX extensions.
NOTE:
The 016 basic telephone module (Release 4.0 and later only) supports a
maximum bit rate of 14.4 kbps. Therefore, the office’s analog equipment
(fax machines and modems) is restricted to speeds no higher than this.
