1621-03: Minimum DP Make Timer
(Minimum Make)
Use this option to de fine the minimum amount of time the loop must be closed to properly decode\
 the dial 
pulse digits sent from analog devices connected to single line PCBs.  Change this value only if the con-
nected analog devices are set to dial at a rate other than 10 PPS.

Use this option to define the maximum amount of time the loop must be closed to properly decode\
 the dial 
pulse digits sent from analog devices connected to SLIU PCBs.  Change this value only if the connected

(Minimum Flash)
For single line PCBs, use this option to de fine the minimum amount of time the loop must be opened before 
the system starts to detect a transfer or hang up sequence. Open loop in\
tervals shorter than the setting are 
ignored by the PCB.

1622-01: Loop Disconnect Timer
(Loop Disconnect)
Use this option to determine how long the single line PCB opens the loop to the connected analog device 
after the far end disconnects. This timer is used only if 1403-06: Loop Disconnect for Single Line Set

(MW Period)
Use this option to determine the ringing sequence for the devices connected single line PCBs. Because of 
power consumption, it is not possible to ring all analog devices on a PCB simultaneously. Instead, the card is 
divided into 4 groups with two ports in each group. Ringing cycles between the 4 groups, ringing each group 
for this interval. F

Options
1631-01: Receive Loop Detection Timer
(Rx Loop Detect)
For loop start T1 lines, loop current must be present for this interval before the system seizes the line. Set 
this interval for compatibility with the T1 service provider. If you set this interval too short, the system may 
inadvertently seize unstable lines. If too long, the system may not properly \
seize a valid line.
