Port State Provisioning
8
Port state provisioning is a feature provided on DDM-2000 OC-12 Multiplexers
that suppresses alarm reporting and PM by supporting multiple states (automatic
[AUTO], in-service [IS], and not-monitored [NMON]) for DS3 and EC-1 ports.
Ports without signals (undriven) are in the AUTO state until changed to the IS
state when a signal is present. The
set-state-t3
and
set-state-ec1
commands allow a user to change the state of a port to the NMON state or from
the NMON state to the AUTO state. The
rtrv-state-eqpt
,
rtrv-t3
, and
rtrv-ec1
commands allow a user to retrieve current port states. The
upd
command allows a user to change the port state of all undriven ports from IS to
AUTO.
Channel State Provisioning
8
Channel state provisioning is a feature provided on DDM-2000 OC-12
Multiplexers that suppresses reporting of alarms and events for STS-1 channels
by supporting multiple states at the OC-12 ports (AUTO, IS, and NMON) for these
channels. The
rtrv-state-sts1
command allows a user to retrieve current
channel states.
While an end-to-end circuit is being set up, particularly during STS-1 cross-
connection provisioning, transient maintenance signals may result. Without
automatic channel state provisioning, these are reported as alarms or events. The
technicians are expected to ignore these transient alarms and initiate corrective
action only if the alarms persist after the provisioning is completed.
To avoid the confusion created by this, DDM-2000 OC-12 Multiplexers provide
automatic channel state provisioning. An STS-1 channel stays in the default
AUTO state until a valid signal, a framed signal that is not alarm indication signal
(AIS) or unequipped is received on that channel. While in AUTO state, no alarms
or events are reported on the channel by the DDM-2000 OC-12 Multiplexer. On
receiving a valid signal, which occurs when the end-to-end circuit is completely
provisioned, the channel automatically changes to the IS state, and normal alarm
and event reporting starts. An additional state, NMON, is also supported in which
alarm and event reporting is suppressed regardless of the validity of the signal
being received on the channel. Like the port state provisioning capability provided
for DS3 and EC-1 ports, the user can use CIT or TL1 commands to manually
change a channel from IS or AUTO to NMON, and from NMON to AUTO. A direct
change from NMON to IS is not allowed. See the
set-state-sts1
,
rtrv-
state-sts1
and
upd
commands.
