Administration and Provisioning
8-12
Issue 3 June 2000
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 DS1 ports, the user can use CIT 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
,
set-state-vt1
,
rtrv-state-sts1
,
rtrv-state-vt1
and
upd
commands.
Line State Provisioning
8
For DDM-2000 FiberReach, OC-1 ring interfaces can be set manually to NMON or
IS.
AIS or Unequipped Provisioning
8
In DDM-2000 FiberReach the shelf can be optioned to send an "STS/VT-path
unequipped" signal instead of path AIS when a DS1 pack is removed or when a
cross-connection is removed.
Data Communications Channel (DCC)
Provisioning
8
The DCC is used for operations communications between NEs. The DCC is part
of the SONET overhead on all optical transmission lines.
In a given subnetwork, the NEs on each side of an optical span must have their
"userside/networkside" (OSI terminology) parameters provisioned to opposite
values. Local procedures should determine the "user" and "network" side of a
span. For example, the CO terminal can be designated the network side and the
RT site the user side. It does not matter as long as the two sides are opposite
values. See the TOP section of this manual for provisioning procedures.
In ring systems, there is one DCC assigned for the "m1" ring and another DCC for
the "m2" ring.
Operations Interworking (OI) Provisioning
8
OI provides the capability to access, operate, administer, maintain, and provision
remote Lucent NEs from other NEs in a subnetwork or from a centralized OS.
OI is supported among systems that are connected through the DCC. Table 8-1
lists the SONET software compatibility within a subnetwork for the Lucent 2000
