■
Multi-media Data Services: A new DS3 (BBG19) interface provides the
flexibility to offer a full range of multi-media data services via embedded
and new DDM-2000 networks. This full-solution offering is made possible
by interfacing DDM-2000 to any of the numerous commercially available
data edge devices which provide the various data services interfaces.
■
The HDSL circuit pack (BBF8) provides for HDSL interface capability on
the DDM-2000 FiberReach shelf. It allows the transport of DS1 rate
payloads, for up to 12,000 feet, over two metallic 24 AWG twisted-pair lines.
Data is transported over each pair bidirectionally using echo cancellation
techniques.
Release 4.0
supports the following applications and features:
■
OC-12 optics through the 29G-U/29H-U OLIU circuit packs in the Main Unit
slots. The related features are as follows.
— STS-1/STS-3c/VT1.5 pass-through cross-connections on the 29G-
U/29H-U OC-3 equipped shelves
— STS-3c cross-connections to Function Unit
— In-service upgrades only from 28G-types to the new 29-type OLIUs.
■
DCC provisioning on Main (identical/distinct) for OC-3/OC-12 ring interface.
Identical DCC mode allows a remote shelf to interconnect through its Main
ring interfaces with a 1+1 linear extension on a host OC-3, OC-12, or OC-
48 shelf using ring software.
■
Provisioning of asynchronous CIT port to run TL1.
■
Remote alarm status (using the AGNE and the Alarm Group concept).
■
CPro-2000, ITM SNC support: Release 4.0 is supported by:
CPro-2000 Release 10.0; ITM SNC Release 10.0
■
DS3 using BBG4/BBG4B while using the OC-1 optics in the Main.
■
Multimedia Data Services using DS3 BBG19 for Lucent DDM-2000
FiberReach NE (used for DS3 locked cross-connects, to support data
services), while using the OC-1 (26-type) OLIUs in Main. (The BBG19 in
the Function Unit slots is currently supported with the 28-type OLIUs in
Main to provide this type of service.)
