Loop Disconnect Time
When the Model 748 has seized or gone off-hook on a phone line, it has completed a series circuit
with the local central office or PBX. Loop current is present and can be detected by the Model 748.
Loop disconnect
time is the amount of time that it will allow for “loss of loop current” before
disconnecting the call. This can be used to support “called party disconnect” where a momentary
break in loop current is provided when the distant party hangs up. The range for this command is 10
to 254 milliseconds.
It can also be disabled by setting it to 255.
