In Release 4.1, one or more FT-2000 OC-48 Add/Drop-Rings Terminals in a ring
network may be provisioned as a GNE using the CIT. In Release 5 and later
releases, the GNE function is no longer CIT provisionable. Any FT-2000 OC-48
Add/Drop-Rings Terminal in a ring network will automatically operate as a GNE if
it receives TL1 messages through the local X.25 interface that are for another
node in the ring network.
In Release 6 and later releases, one or more FT-2000 OC-48 Add/Drop-Rings
Terminals can serve as a single interface to the local X.25 message-based
operations system for the DDM-2000 Multiplexers through the OC-3 DCC
(Figure 2-23). The GNE also serves as a single interface for all FT-2000 OC-48
Add/Drop-Rings Terminals in the same ring network and in the same subnetwork.
When Release 6 of the FT-2000 OC-48 Add/Drop-Rings Terminal interworks with
Release 7.2 or Release 9 of the DDM-2000 OC-3 Multiplexer, the recommended
maximum subnetwork size is 24 NEs. When Release 7 of the FT-2000 OC-48
Add/Drop-Rings Terminal interworks with Release 7.2 or Release 9 of the
DDM-2000 OC-3 Multiplexer, the recommended maximum subnetwork size is 32
NEs.
