NOTE:
If a port is in the
nmon (n)
state, the signal is not monitored
or alarmed. The port will not automatically go to the
in
service (i)
state when a signal is detected as it will in the
auto
(a)
state. In the
nmon
state, the port must be returned to the
auto state, using the set-state-t1: command, to turn on
monitoring of signal failures and before any circuit packs
associated with that port can be removed from the
equipment list by the upd command.
If circuit packs are going to be removed, use the
rtrv-state-t1:/set-state-t1: command to verify/set the
port state of the T1 ports to
auto
.
If circuit packs are
not
going to be removed, use the
set-state-t1: command to set the port state of the T1 port(s)
to
auto
or
nmon
, as required.
10. If both T1 ports on the
T1EXT
circuit pack are being discontinued,
you may remove the
T1EXT
circuit pack, if required.
11. If circuit packs have been removed, momentarily depress the
UPD/INIT
button on the
SYSCTL
or use the upd command to
update the DDM-2000 internal equipment list.
12. If the FiberReach shelf is equipped for 1X7 protection mode and
circuit packs have been removed, install
177A
Apparatus Blank
