Administration and Provisioning
Issue 8.0 July 2002
8-123
— The DS1 Out 2 Equalization parameter provisions the DS1 Out 2 to
drive "20, 40, 60, 80, or 100" percent of its maximum rated cable
length. The cable lengths are based on YR28365 cable. Provision
the equalization to the smallest value greater than the actual cable
length based on the following:
■ CONFIGURATION-Set-T3 (TL1 = ENT-rr): This input sets the VMR
mode, Alarm Level, and Signal Degrade Threshold of DS3 interface ports.
These parameters can be provisioned when the selected low-speed
interface slot(s) is unequipped or equipped with any type low-speed
interface circuit pack. Thus, it is permissible to preprovision low-speed
interface slots for DS3 interfaces.
— The Violation Monitor Removal parameter sets the mode of the
Violation Monitor and Removal (VMR) function of the addressed
DS3 ports. The choices are:
— "VMR": DS3 P-bit parity errors in the output DS3 (towards the
cross-connect panel) are monitored and removed.
— "VM": DS3 P-bit parity error in the output DS3 (towards the
cross-connect panel) are monitored and not removed.
— "CC w/AIS": The incoming DS3 signal (from the OC-48 line)
is transmitted to the cross-connect panel without DS3 format
violation monitoring (clear channel). DS3 AIS is inserted
toward the OC-48 line, if there are excessive bipolar
violations or there is loss of signal from the cross-connect
panel. DS3 AIS is passed through in both directions.
— "CC w/o AIS": Same as CC w/AIS, except DS3 AIS is not
inserted.
— The Alarm Level
*
parameter sets the severity of an incoming (from
the cross-connect panel) signal failure condition. The choices are:
- "CR": critical
-"MJ":major
- "MN": minor
Optimum Equalization
Setting (Percent)
Cable Length to
DSX-1 Panel (Feet)
20 0 - 133
40 133 - 267
60 267 - 400
80 400 - 533
100 533 - 655
* If the DS3 port is part of a 1-way-DRI cross-connection, the alarm level should be
provisioned minor (MN).
