Administration and Provisioning
8-22
Issue 3 June 2000
After the
init-sys:all
or
init-sys:systcl
command is entered, the
system sets the TID to a default value of LT-DDM-2000. The TID must be
unique among all NEs. The default TID may be changed using the
set-ne
command to a unique user-assigned value recognized by the OS.
■
NSAP:
The network services access point (NSAP) is a multiple part
address that uniquely identifies the NE. The NSAP is used for subnetwork
DCC communications using the OSI protocol. The NSAP is set to unique
values assigned to control hardware at the factory and does not have to be
modified by the user unless subnetwork partitioning is necessary.
Subnetwork partitioning is accomplished by assigning NEs to different
areas. An NE’s area address is one of the subfields within its NSAP.
The
ent-ulsdcc-l3
command is used to modify an NE’s NSAP.
■
CO/RT:
The CO/RT parameter for CO or RT identifies the system as
having the characteristics of a CO or RT. The default is RT. The parameter
controls the operation of the miscellaneous discretes and the external fan
control.

Cross-Connection Provisioning
8
Traffic is transported through the SONET network via dedicated, software-
provisioned, VT1.5 or STS-1 time slot transmission paths. For each transmission
path through a network ring, a cross-connection is needed in every NE (node) on
the ring. The time slot interchange (TSI) feature of DDM-2000 FiberReach
Multiplexers offers users flexibility in directing traffic in and out of these systems to
support a wide variety and range of customer applications.
In an hairpin application, no cross-connection using a high speed interfaces is
needed on the node in the hosting ring because no signal is transported through
the high-speed interfaces in the host ring.
For the DDM-2000 Multiplexers, cross-connections of both ring paths are entered
with a single command entry per shelf. This minimizes the possibility of
provisioning a circuit without a protection channel. The ring channels are always
carried within the OLIU circuit packs in the Main 1 and Main 2 slots. Cross-
connections in DDM-2000 Multiplexers are made by specifying the SONET rate
(VT1.5 or STS-1), the end point addresses (access identifiers), the cross-
connection type (two way, locked, etc.) and, in some cases, the ring direction
(ring=m1, ring=m2, etc.). In DDM-2000 Multiplexers, each single cross-connection
command establishes a bidirectional cross-connection. There is no need to
