Strata CTX General Description 11/02
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 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
The processor has LSI circuits that support the following:
• 16 DTMF receivers – requires ARCS and, for five or more DTMF receivers, requires
appropriate licenses. See
“CTX100 License Control” on page 4 .
• 16 Busy Tone (BT) detectors for Auto Busy Redial (ABR) – requires ARCS.
• 64 built-in conference circuits (see Table 7 on page 13 for more information).
• Built-in, adjustable, digital volume PAD technology enables audio volume to be adjusted in
eight steps to compensate for conference and/or CO line 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.
External Page Interface
A 600 ohm RCA jack is built into the processor to interface with a Toshiba External Amplified
Speaker (HESB) or a customer-supplied page amplifier and speaker(s) for external paging, night
ring over external page, and external BGM applications.
Music-on-hold/Background Music Interface
A 600-ohm RCA jack 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
SmartMedia Memory
The processor has an on-board SmartMedia TM memory card slot. A SmartMedia flash memory
card can be inserted into the slot to backup and restore customer program data. It also makes it
easy to upload operating system data for software upgrades and is used for maintenance functions
(see
“System Fault Finding and Diagnostics” on page 66 for more details).
