The ADTRAN DDST IV is a high-performance auto-rate adaptive digital
network interface unit for DDS and Switch 56 transmission over a 4-wire
loop with up to 45dB of loss. The DDST IV adds intelligence and compre-
hensive DS0 Performance Monitoring to digital circuits by monitoring both
the network and the equipment sides for error performance and signal
quality. Utilizing advancements in VLSI and custom integrated circuit tech-
nology, this low cost unit provides all rate capability and real-time error
reporting. Automatic adaptive equalization is employed, permitting reliable
reception of low loop signals, eliminating the need for loop repeaters in
many installations.
The DDST IV reports “far-end” DS0 loop performance information to the
ADTRAN SD4 OCU DP/PM, an intelligent OCU dataport, non-intrusively,
using an “ESF-like” communication link between the two units. The
communication link provides for analysis of unit provisioning, inventory
information, and comprehensive loop performance information. This
information can be accessed when the OCU DP/PM is deployed in the
ADTRAN ACT 2300/1900 channel banks or standard WECO D4 using the
ADTRAN intelligent LIU-3/PM. These intelligent platforms provide a user
interface to access the OCU DP/PM and DDST IV through a menu driven
interface called EasyMenu™. EasyMenu allows C.O. personnel to view
performance data for historical trending, provision the DDST IV remotely,
and access alarm information for trouble analysis.
The DDST IV is a part of the ADTRAN product line of intelligent network
products used to provide performance monitoring, local and remote provi-
sioning, and enhanced trouble analysis capabilities to new and existing
special services networks. A list of complementary products is found on the
reverse side of this brochure.
