!
CAUTION:
To minimize "hits" on in-service ports on DS1/DS1PM circuit
packs having a port added, it is recommended that a CIT be
used to manually switch (using the
switch-ls:
command)
the DS1 to protection if the DS1/DS1PM circuit pack is
removed or to set channel 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 ports on that circuit pack. If a
CIT is available, use the
rtrv-state-eqpt:
command to
check the status of the protection switch.
!
CAUTION:
When a DS1/DS1PM circuit pack is switched to protection,
removal of any other DS1/DS1PM circuit pack or 177A
Retainer Card in the same group will result in a loss of
service to the protection DS1/DS1PM circuit pack and the
removed DS1/DS1PM circuit pack.
!
CAUTION:
No service DS1 LOW SPEED slots should be left empty in a
group equipped with MXRVO and protection DS1/DS1PM
circuit packs.
DLP-520 Condition DS1/DS1PM circuit pack or port for new DS1 service
being added.
4. At each DS1 terminating node, use the
set-t1:
command to set
the characteristics of the DS1 port being established, if not
already performed.
5. At each DS1 terminating node, make the appropriate cable
connection(s) to the DS1 cross-connect point(s) or equivalent
connection point(s) for the circuit(s) being added.
6. Verify that no LEDs or alarms are activated. If any LEDs or alarms
are activated, refer to Trouble Clearing: IXL-001 and follow the
appropriate trouble-clearing procedure.
