System Introduction
Issue 1
December 1997
1-7
— Provisionable AIS or unequipped conditions. Allows the user to provision,
on a per-shelf basis, for either AIS or unequipped signal insertion on a
non-cross-connected STS channel.
— Provisionable line and path AIS alarm levels. Alarm levels can be
provisioned on a per-line or per-path basis.
— Brownout protection. If the voltage to the shelf drops below the safe
operating voltage, the system will suspend normal operations and wait for
safe operating voltage to return. Assuming a sufficient voltage level, a
flashing "L" will be displayed on the system controller (SYSCTL).
— SYSCTL optical faceplate latch. An optical switch on the BBG8 SYSCTL
circuit pack latch causes a suspension of controller operations and an "F"
to be displayed on the SYSCTL display when the latch is pulled. Closing
the latch causes a controller reset.
— DS3 failure generates STS path AIS. With the OC-12 shelf provisioned for
DS3 DRI, a DS3 failure translates to an STS path AIS to ensure a
downstream STS path switch.
Release 5.1 is an enhanced ring release which supports all features of R5.0. In
addition, it supports the following:
■
New Applications:
— Enhanced DS3 Dual Ring Interworking translation of an incoming DS3
failure condition into an STS-1 AIS condition for far-end detection and
STS-1 path switching of the failed DS3.
■
New Features:
— S1 byte Synchronization Messaging. Uses the S1 byte of the SONET
overhead to pass timing status information to different nodes in a loop-
timed network. Synchronization messaging mode (S1 byte or K2 byte) is
provisionable on a per OC-N basis.
— Enhanced software download. Provides a software copy capability which
allows new software generic to be downloaded to the DDM-2000 system
while the current version is still running. When the appropriate command
is initiated, the new generic is executed with no disruption of DCC.
Execution of the new generic can be scheduled, allowing coordination of
cutover of several NEs in the subnetwork.
— Fourth level of security. A new maintenance security level, which allows
access to Reports and some maintenance activities is provided in
addition to the three current levels of privileged, general, and reports-only.
— Large networks. Supports DDM-2000 and FiberReach networks of up to
50 nodes.
— CPro-2000, ITM SNC support. Release 5.1 is supported by:
CPro-2000 Releases 5.0 and 6.0, ITM SNC Releases 2.2 and 4.0.
