ACT1900  
Intelligent D4 Channel Bank  
The ADTRAN® ACT 1900 is an intelligent  
D4 channel bank intended for central  
office (CO) installations where intelligence,  
low-cost com m onality 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  
addressable RS-485 communications link.  
The Site Manager also provides an interface  
to various Operations Support Systems (OSS)  
such as Bellcores 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.

enhances reliability  
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 customers 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.

I Redundant power supply  
units enhance reliability  
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.
