Strata CTX I&M September 2002
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
