DDM-2000 OC-3 MULTIPLEXER
Condition DS1/DS1PM Circuit Pack/Port
for New DS1 Service
1.
NOTE:
The rtrv-alm: and rtrv-state-eqpt: commands may be used to
check for alarms, locks, loops, and switches.
NOTE:
If line code (lc) parameters have been previously set using the set-t1:
command, the circuit pack line code switch settings will have no effect.
There will be no indication of improper switch settings until you try to
establish service. It is recommended that a policy be established to set
line coding either using the switches OR using CIT commands. Use the
rtrv-t1: command to check line code settings.
Use rtrv-alm: command to verify that no alarms, locks, loops, or switches
are present.
2. Is a new DS1/DS1PM circuit pack being installed?
If YES, then proceed to Step 12.
If NO, then continue with Step 3.
3.
!
CAUTION:
To minimize hits on in-service ports on the
DS1/DS1PM
circuit pack
having a DS1 port added, it is recommended to either use a CIT to
manually switch the DS1 to protection if the
DS1/DS1PM
circuit pack
must be removed, or use the CIT to set DS1 port options without
removing the circuit pack.
!
CAUTION:
If the protection
DS1/DS1PM
circuit pack is not available for a protection
switch, removing a service
DS1/DS1PM
circuit pack will interrupt service
on all DS1 ports on that circuit pack. If a CIT is available, use the
rtrv-state:
command to check the status of the protection switch.
