FF2
Trunk Disconnect Detection Timer
Software Version CPC-S and CPC-M, Version 1 0 and higher
Address FF2 (Trunk)# 18# (0-15)#
Description
When the trunk side of a CO call disconnects, the CO sends the DBS 824 a
disconnect signal by opening the loop (cutting voltage) for a specified length
of time
This timer determines how long the DBS 824 expects the disconnect signal to
last. If set to 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
