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.
