System Introduction
1-10 Issue 3 June 2001
— New controllers. The new BBG8/BBG8B and BBG9 controller circuit
packs provide expanded memory and processing capacity needed
to support large networks. Feature enhancements available with the
new controllers include:
— Remote software download. Software can be downloaded
from a PC connected to a DDM-2000/
SLC
-2000 NE to either
the local or remote DDM-2000/
SLC
-2000 NE.
— Electronic provisioning. Provisionable parameters are set by
software, thus decreasing the need for DIP switches. CIT
baud rate is provisioned automatically via autobaud
detection.
— User-assigned RT miscellaneous discretes increased from
15 to 21.
— Upgrades to the new controllers can be done in service.
— Enhanced PM. Enhancements to DS1 and DS3 line and path PM to
further support tariff verification. Enhanced DS3 PM requires the
new BBG4B DS3 circuit pack.
— Enhanced security. General and reports-only users increased from
50 to 100. Lockout of nonpriviliged users and log of all login
attempts is provided.
— Electrical facility loopbacks. DS1, DS3, and EC-1 equipment
loopbacks of the incoming low-speed signal back towards the DSX.
— 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.
— 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, an "L" will be displayed on the system controller
(SYSCTL).
