— Additional X.25 switched virtual circuits. Nine virtual circuits can be
provisioned in any combination of switched and permanent virtual
circuits for connections to OSs.
— Provisionable X.25 packet size of 128 or 256 bytes.
— Centralized operations over X.25 link. DDM-2000 CIT commands
have equivalent TL1 commands. This allows centralized operations
of DDM-2000 systems via the TL1/X.25 link as an alternative to CIT
commands.
— New controllers. The new BBG8 and BCP4 controller circuit packs
provide expanded memory and processing capacity needed to
support large networks. Feature enhancements 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 NEs.
■
Electronic provisioning. Provisionable parameters are set by
software, thus reducing 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 DS3 line and path PM to further
support tariff verification. Enhanced DS3 PM requires the new
BBG11B 3DS3 circuit pack.
— Path switching and channel state provisioning for STS-3c channels.
— Line state provisioning. A capability provided on DDM-2000 OC-12
Multiplexers that suppresses reporting of alarms and events by
supporting multiple states (IS and NMON) for OC-3 low-speed
interfaces.
— Enhanced security. General- and reports-only users increased from
50 to 100. Lockout of nonprivileged users and log of all login
attempts is provided.
— Electrical facility loopbacks. 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. The path trace signal is used
to verify path continuity by repetitively transmitting a fixed 64 byte
length string. The value of the transmit and receive expected path
trace signal is provisionable. The value of the provisionable receive
expected path trace signal is compared to the actual received path
trace signal to verify continuity. This allows "labeling" of STS-1s and
retrieval of the path by the "label” (for example, "ABC #1"). STS path
trace requires the new BBG11B 3DS3 circuit pack.
