Instruction manual

Features
The system allows an authorization code to be entered with the Account
Code Entry feature. This is especially useful for data calls.
■ SID-ANI as Calling Party Number (CPN) (Release 2.0 and later)
The CPN in Release 1.0 is facility-based, whereas it can be station-
based in Release 2.0 if system programmed. Station-based CPN is
called SID-ANI and results in a more PBX-like performance from the
system.
Considerations and Constraints
General
If a B-channel is not available when a call is placed, a fast busy tone is
returned. While the tone is in progress, the line on which the call was placed is
considered busy. If the originator goes on-hook while the tone is in progress,
the call is ended and the line is idled. Otherwise, the call appearance is
removed and the line is idled 15 seconds after the tone is applied.
A telephone is considered busy if no SA button (non-originate only) is available,
Do Not Disturb is activated, or the telephone is in program, forced idle, or alarm
clock mode. The caller hears a busy tone. The call will receive Coverage, if
specified.
A PRI line can be in only one B-channel group.
If the internal Dial Plan uses extension numbers with different numbers of digits,
for example, both 3-digit extension numbers and 4-digit extension numbers,
SID-ANI might not work properly.
The PRI telephone number assigned to each channel must be different from the
numbers assigned to other channels assigned to the same B-channel group
and from that of the associated test number. Also, the number each channel
must be the same number as that provided by the PRI service provider.
The Test Telephone Number assigned for each 100D (DS1) module in the
control unit must be different from the numbers assigned to other channels in
the same B-channel group and must be the same number as that provided by
the PRI service provider.
An invalid timer value entered in system programming results in that number
being truncated to the closest valid value. If, for example, 45 is entered for a
counter that ranges from 0 to 30 seconds, 4 is recorded.
Incoming Calls
When an incoming call is given Routing by Dial Plan treatment, the green LED
associated with appearances of the line lights steady; the LED does not flash to
indicate that the trunk is ringing. The green LED associated with the Personal
Line lights steadily, and ringing on an SA button occurs; the LED does not flash
to indicate that the trunk is ringing.
