Ctx100 Processor; Cpu/Memory; Large Scale Integrated (Lsi) Circuits; Memory Protection Battery - Toshiba Strara CTX Series Installation And Maintenance Manual

Strata CTX Configuration
Each CTX100 system has a Base Cabinet with one optional Expansion Cabinet. All lines, stations, and
options are tied together through the cabinets. The overall weight and dimensions of the CTX100
cabinets are shown in

CTX100 Processor

The system operates with one processor circuit board (ACTU) that installs in a dedicated slot of the
Base Cabinet. The ACTU processor incorporates the following on-board hardware features:

CPU/Memory

The CTX100 uses a high-speed, 32-bit, RISC processor, Dynamic Random Access Memory (DRAM)
working memory, Static Random Access Memory (SRAM) with lithium battery for memory back-up,
and flash program memory.

Large Scale Integrated (LSI) Circuits

Custom Toshiba LSI circuits provide on-board conference switching circuits for up to eight-party
conferences and digital Pad circuits to adjust audio volume levels in eight steps to compensate for
conference and/or network losses.

Memory Protection Battery

If commercial AC power is lost or if a system is moved or stored without power, the processor has an
on-board battery that protects data and the customer's programmed configuration from memory loss.
This information will be maintained in a powerless system for at least six years.

Relay Control Interface

An on-board terminal strip provides an interface to a normally open relay contact which can be
programmed to control a Night Bell, door lock or to mute BGM during an external page.

Music-on-hold/Background Music Interface

Two RCA jacks and volume controls are built into the processor to interface with Music-on-hold and/
or Background Music (BGM) sources (one of the jacks is for future use). With the CTX100, you can
have up to 15 MOH/BGM source interfaces by adding:
Up to two BIOU PCBs, each provides three MOH/BGM input sources
An RSTU PCB that provides up to eight MOH/BGM input sources
