Understanding The
System Features
A
Abandoned Hold Release
If an on-hold party hangs up at the CO/PBX end of a connection, causing an interruption
in the line current, the system will drop the line from the hold condition and return it to
service. The time interval between hang-up and line-drop is programmable in line class
of service programming with choices of either 50 msec or 350 msec. This feature is
usually dependent upon special arrangements that must be made at the CO end of the
connection. The line select indicator will turn off to indicate an idle line after a call on
that line has been abandoned.

Access Denied
The system programmer can deny access to particular lines at certain stations in the
system. A station user cannot select a denied line for use. This feature is programmable
on a per line/per station basis in station class of service programming.
