ANSWER BACK TIME. This timer is used for certain
types of E & M signaling and does not affect normal
CO lines.
0-2500 MSEC
01
CLEARING
This timer ensures that a call is fully disconnected at
the CO by preventing CO access outgoing or
receiving incoming ring between a disconnect and
the expiration of this timer.
100-9900 MSEC
02
CO SUPV TM
CO SUPERVISION TIME. this is the minimum
length of loop open disconnect received from the
CO that will be seen as a valid hang up on the
system.
10-2500 MSEC
03
DTMF DUR.
DTMF DURATION. This is the length of the DTMF
digits that will be sent to the CO on this line.
100-9900 MSEC
04
F-DGT DELY
First-DIGIT DELAY. This is the length of time the
system will wait for CO line conditions to stabilize
after seizure before sending DTMF digits.
100-9900 MSEC
05
FLASH TIME
This is the duration of the momentary open sent on
a circuit when FLASH key is pressed.
20-2500 MSEC
