Condition T1EXT Circuit Pack/Port
for New T1 Service
1.
!
CAUTION:
When using the
T1EXT
circuit pack, primary lightning protection and a
lightning protection shelf must be used.
NOTE:
The commands rtrv-alm and rtrv-state 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 T1EXT circuit pack being installed?
If YES, proceed to Step 5.
If NO, continue with Step 3.
3.
!
CAUTION:
To minimize hits on in-service ports on the
T1EXT
circuit pack having a
T1 port added, it is recommended to either use a CIT to manually switch
the T1 to protection if the
T1EXT
circuit pack must be removed, or use
the CIT to set T1 port options without removing the circuit pack.
!
CAUTION:
Removing a service
T1EXT
circuit pack that does not have an associated
protection
T1EXT
circuit pack installed will interrupt service on all T1
ports on that circuit pack.
Use set-t1: command to set T1EXT port options.
