Line State Provisioning 8
OC-1 ring interfaces can be set manually to NMON or IS.
AIS or Unequipped Provisioning 8
In DDM-2000 OC-3, if a DS1, DS3, TMUX, or MXRVO circuit pack is removed, or
when a cross-connection is removed, the system can be optioned to send either a
"path AIS" signal or an "STS/VT-path unequipped" signal.
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
Thereisnolimitationonthesizeofthenetworksformedbysplittingalarge
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.
