1-4 Access System Centum Series User Manual
The Centum Series also includes a built-in bit error rate tester (BERT),
eliminating the need for external test equipment. The built-in tester
transmits a 511-bit pseudo random test pattern. The Centum Series
records errors received, seconds in test, and error-free seconds.
Alarm conditions are displayed on the front panel LCD screen as well as
on the console’s Alarms/Statistics screen. Front panel LEDs indicate unit
and control signal status.
ESF Operation
Centum Series Extended SuperFrame (ESF) operation allows the
telephone company central office to continuously monitor the local loop,
to transmit and receive test messages, and to retrieve performance data,
without interrupting normal operations. The unit is compatible with both
AT&T 54016 and ANSI T1.403 specifications.
Clear Channel
The Centum Series provides clear channel signalling with B8ZS line
coding (in installations where it is supported by the Telco central office)
or alternate channel assignment.
Specifications
Product specifications for the Centum Series are listed on the following
