Line State Provisioning
8
Line state provisioning is a feature provided on DDM-2000 OC-12 Multiplexers that
suppresses alarm reporting and PM by supporting multiple states (IS and NMON) for
OC-3 lines. See the
set-state-oc3
and
rtrv-state-oc3
commands.
Remote OS Access (TL1/X.25 GNE)
8
A DDM-2000 subnetwork may have one or more NEs serving as TL1/X.25 GNEs.
Without any user provisioning, a DDM-2000 is automatically a GNE upon connecting an
X.25 link to its X.25 interface. Refer to the “TL1/X.25 Interfaces” paragraph in Section 6,
“Operations Interfaces,” for more information.
Remote CIT Login
8
Each DDM-2000 Multiplexer can remotely log into other DDM-2000 Multiplexers in the
same subnetwork. OI also allows remote logins between DDM-2000 and the
SLC-2000
Access System and from the FT-2000 OC-48 Lightwave System to other Lucent 2000
Product Family systems in the same subnetwork. Refer to Section 6, “Operations
Interfaces,” for more information.
Remote Software Download and Copy
8
The DDM-2000 OC-3 and OC-12 Multiplexers can upgrade the system software while
in-service. Software can be downloaded locally using a PC through the EIA-232-D
interface on the user panel or remotely over the SONET DCC. Refer to the “Software
Upgrades” section at the beginning of this chapter for more information.
Subnetwork Size
8
There is no limitation on the size of the networks formed by splitting a large network into
a number of smaller maintenance subnetworks by disabling the DCC between the
subnetworks. Subnetwork partitioning can be done while in service without affecting
traffic. Subnetwork sizes of up to 256 NEs are supported via subnetwork partitioning
(50 per level 1 area, 256 per subnetwork) with multiple areas connected via level 2
Intermediate Systems (IS). Refer to 824-102-144,
Lucent Technologies 2000 Product
Family Multi-Vendor Operations Interworking Guide, for additional information.
