Description
Range
00
ANS.BAK TM
ANSWER BACK TIME. This timer is used for certain
types of E & M signalling 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 receiv-
ing 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 sys-
tem.
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
06
NO RING TM
This is the length of time the system will wait after
detecting a ring burst on a line before deciding the
call has disconnected.
1-25 SEC
07
PAUSE TIME
This is the length of time the system will wait before
sending the next digit for a pause in a speed dial
bin.
1-25 SEC
08
PRS DET TM
This means the duration of PRS signal pulse. If the
PRS signal is reversed when opposite party is an-
swered and maintain the status before the opposite
party disconnect the call, the PRS DET TM must be
set to 0.
0-2500 MSEC
09
RNG DET TM
RING DETECT TIME. This is the minimum length of
ring signal the system will regard as a valid ring.
10-2500 MSEC
10
WINK TIME
This is the duration of the acknowledgment signal
that the system will send on an E&M circuit
100-300 MSEC
11
MF/DP INT
This is the interval between sending digit. In case of
DTMF signal, over the 500ms will be serviced as
100 ms.
100-9900 MSEC
12
MFR DLY TM
This is a delay time to allocate the MFR after incom-
ing trunk is detected. This is to prevent the wrong
detection of DTMF signal by noise.
0-25 SEC
