Strata CTX670 Overview
The Strata CTX670 system provides sophisticated
telecommunication features in a modular system
designed for growth. Its universal slot architecture
enables you to select the combination of Central Office
(CO) lines, stations, and peripheral options that best suit
your needs.

The CTX670 basic BCTU processor can be configured
for smaller systems as a one or two cabinet system with a
capacity of up to 192 CO lines and stations combined. It
can expand to support up to seven cabinets with a
capacity of up to 672 CO lines and stations combined
with the BCTU/BEXU processors (see
