Strata CTX100-S / CTX100 Overview
CTX100-S and CTX100 Processors
12 Strata CTX General Description 10/04
CTX100-S and CTX100 Processors
Each system operates with one processor card (ACTU2A-S for CTX100-S, ACTU2A for
CTX100) that installs in a dedicated slot of the Base Cabinet. The processors incorporate the
following hardware features.
CPU/Memory
Either processor card 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 processors each have LSI circuits that support the following:
• 16 DTMF receiver hardware processor are built into the ACTU2. Five or more DTMF
receivers requires appropriate licenses. See
“CTX100-S/CTX100 License Control” on page 14.
• 16 Busy Tone (BT) detector circuits for Auto Busy Redial (ABR) are built into the ACTU2.
• 64 built-in conference circuits (see Table 12 on page 26 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, either 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 each 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 each 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 circuit cards, each provides three MOH/BGM input sources
• An RSTU circuit card that provides up to eight MOH/BGM input sources
SmartMedia Memory
Each 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 95 for more details).
