Strata CTX Configuration
CTX100-S and CTX100 Processors
2-2 Strata CTX I&M 06/04
The CTX100 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. All lines, stations, and options are tied together through the cabinets.
CTX100-S and CTX100 Processors
Each system operates with one processor PCB (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 PCB 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 2-4.
• 16 Busy Tone (BT) detector circuits for Auto Busy Redial (ABR) are built into the ACTU2.
• 64 built-in conference circuits (see Table 2-7 on page 2-12 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 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.
