The ADTRAN

ACT 1900 is an intelligent

D4 channel bank intended for central

office (CO) installations where intelligence,

low-cost commonality of channel units,and

high reliability are desired. Based on industry

standard D4 technology, the ACT 1900 accom-

modates a wide variety of low-cost channel

units from numerous suppliers. Intelligent

ADTRAN channel units, which provide DS0

performance monitoring and remote provi-

sioning capabilities, complement the

advanced functionality of the ACT 1900.

The ACT 1900 benefits from a reduced

common equipment section consisting of

only three common units: Bank Controller

Unit (BCU), Line Interface Unit (LIU), and

Power Supply Unit (PSU). The BCU is an

intelligent controller for the bank providing

non-intrusive communications to the channel

units, control of the multiple communications

ports, and storage of alarm, provisioning, and

performance information. The communica-

tions ports consist of a local craft interface

for terminal control, a modem access port,

and an RS-485 interface to the ADTRAN Site

Manager for management of multiple banks.

Enhancing the control and maintainability

of the ACT 1900, the ADTRAN Site Manager

provides centralized management for as

many as 500 channel banks. It is a low cost,

Network Equipment Building Standard (NEBS)

compliant, VME-based computer, which

connects to the ACT 1900s over a two-wire,

addressable RS-485 communications link.

The Site Manager also provides an interface

to various Operations Support Systems (OSS)

such as Bellcore’s NMA and OPS/INE for

alarm reporting, trouble isolation, and flow-

through provisioning of intelligent ADTRAN

channel units. Several protocols and connec-

tions are available for flexibility and network

integration including TL1, SNMP, and an

internal X.25 interface for WAN management.

The ACT 1900 monitors both the DS1

performance as well as the DS0 performance

at the channel unit level. ADTRAN intelligent

Performance Monitoring, or PM, channel

units monitor the performance of the local

loop to the customer’s equipment and non-

intrusively report the data collected to the

BCU for storage for a maximum of seven days.

The PM units are also provisionable either

locally or remotely using the BCU craft inter-

face and Site Manager, respectively. Six

intelligent PM units are available: OCU

DP/PM, DS0 DP/PM, U-BR1TE PM, E&M/TO

PM, FXO/DPT PM, AND FXS/DPO PM. The

DS0 performance information consists of

parameters such as error performance, signal

level, open-loop condition, and channel unit

alarm or out-of-service condition.
