System Introduction
Issue 3 June 2001
1-13
— STS path trace. Provided in the J1 byte of the SONET path
overhead to verify STS path continuity. Allows "labeling" of STS-1s
and retrieval of the path by the "label." For example, "ABC #1." STS
path trace requires the new BBG4B DS3 circuit pack.
— Provisionable AIS or unequipped conditions. Path AIS provisionable
on a path basis. Provides user provisionable generation of AIS or
path unequipped signal on a per-shelf basis. Useful in managing
cross-connection provisioning if cross-connections are inadvertently
deleted.
— Provisionable line and path AIS alarm levels. Alarm levels can be
provisioned on a per-line or per-path basis.
— OC-1 line state provisioning. A capability provided on DDM-2000
OC-3 Multiplexers that suppresses reporting of alarms and events
by supporting multiple states (in-service and not monitored) for OC-
1 lines.
— 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 an insufficient
voltage level, an "L" will be displayed on the SYSCTL.
— SYSCTL optical faceplate latch. An optical switch on the BBG8/
BBG8B SYSCTL circuit pack latch causes a suspension of
controller operations and an "F" to be displayed on the controller
panel display when the latch is pulled. Closing the latch causes a
controller reset.
Release 9.1 is a ring release which provides all the features of Release 9.0 and
requires the BBG8/BBG8B and BBG9 or BBG10 controller hardware. In addition,
Release 9.1 supports the following applications and features:
■ New Applications:
—
MegaStar 2000 SONET Radio. Part of Lucent Technologies and
Harris-Farinon
MegaStar 2000 Radio system supporting mixed fiber
and radio topologies.
MegaStar 2000 applications require BBG10
OHCTL.
— Extended FiberReach topologies. Using the new 27G2-U OLIU and
Release 2.0 or 2.1 of FiberReach, Release 9.1 supports:
■ Hairpin single and dual 0x1 cross-connects between OC-1s
within the same 27G2-U OLIU.
■ Hairpin single and dual 0x1 cross-connects between 27G2-U
OLIUs in different function units.
■ Pass-through cross-connects for an OC-1 ring terminated on
27G2-U OLIUs in a function unit.
■ Mixing of all supported cross-connect types.
