Operations Interfaces
6-24 Issue 8.0 July 2002
Terminals in a ring network may be provisioned as the GNE. For more
information about provisioning, refer to Volume I, Section 8, "Administration and
Provisioning." 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, an FT-2000 OC-48 Add/Drop-Rings Terminal can
also operate as a TL1 gateway network element for other FT-2000 OC-48
Add/Drop-Rings Terminals and DDM-2000 Multiplexers present in the
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 network elements. 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 network elements. When Release 7.1.0 of the FT-2000
OC-48 ADR Terminal interworks with Release 9.1 of the DDM-2000 OC-3 and/or
Release 5.1 of the DDM-2000 OC-12, the recommended maximum subnetwork
size is 32 network elements.
!
CAUTION:
In subnetworks with more than 16 NEs, the NE serving as the TL1 gateway
NE CANNOT serve as the AGNE, nor can it serve as the DS-NE. The
AGNE, TL1 gateway NE, as well as the DS-NE functions must be
distributed (i.e., at three separate NEs in the subnetwork).
The following autonomous messages are supported:
REPORT ALARM (REPT ALM) — autonomous reports of alarm condition
REPORT ALARM ENVIRONMENT (REPT ALM ENV) —
autonomous reports of environmental alarm conditions
REPORT CONDITIONS (REPT COND)
*
— autonomous reports of active
status (nonalarmed) conditions
* Available in Releases 5 and later.
REPORT DATABASE CHANGES (REPT DBCHG)* — autonomous reports of
internal cross-connection changes and line (OC-48, OC-12, OC-3, EC-1,
and DS3) termination parameters
REPORT EVENT (REPT EVT) — autonomous reports of status conditions,
including performance-monitoring threshold-crossing alerts (TCAs)
REPORT SWITCH (REPT SW)
†
— autonomous reports of electrical low
speed interface circuit pack (DS3 and STS1E), or TG3 (DS1) circuit pack
protection switches.
† Available in Releases 4.1 through 7.1.
