Trunk Disconnect Detection Timer
Software Version: All Versions
Address: FF2 (Trunk)# 18# (0-15)#
Description
When the trunk side of a CO call disconnects, the CO sends the DBS a
disconnect signal by opening the loop (cutting voltage) for a specified length
of time.
This timer determines how long the DBS expects the disconnect signal to last.
By default, an open loop of 350 ms or more will be interpreted as a disconnect
signal.
The standard range for CO disconnect signals is 350 to 600 ms.
