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 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
(see
Figure
1-2).
System line and station capacity is expanded by adding
processor expansion Printed Circuit Boards (PCBs),
cabinets and line/station PCBs.
The CTX670 easily connects to outside public and
private telephone lines. All of the telephones (stations)
tied to the system can have direct access to each other as
well as to the public and private network.
The Base Cabinet and optional Expansion Cabinets are the building blocks of the system. Each
system has a Base Cabinet, and can have from one to six Expansion Cabinets. All lines, stations,
and options are tied together through the cabinets.

CTX670 Processor PCBs
The system operates with one set of processor PCBs (BECU/BBCU) that install in dedicated slots
of the Base Cabinet. The BECU/BBCU processor incorporates the following on-board hardware
features:
CPU/Memory
The CTX670 uses a high-speed, 32-bit, Reduced Instruction Set Computing (RISC) processor,
Dynamic Random Access Memory (DRAM) working memory, Static Random Access Memory
(SRAM) with lithium battery for back-up memory, and flash program memory.
