CIX670 Processor Circuit Cards

CIX670 Processor Circuit Cards
The system operates with the BCTU only or the BCTU and BEXU processor circuit cards that
install in dedicated slots of the Base Cabinet. The BCTU and BEXU processor incorporates the
following on-board hardware features:

CPU/Memory

The CIX670 uses a high-speed, 32-bit, Reduced Instruction Set Computing (RISC) processor,
Dynamic Random Access Memory (DRAM) working memory, Static Random Access Memory
(SRAM) with lithium battery for back-up memory and flash program memory.

Large-scale Integrated (LSI) circuits

The processor has LSI circuits that support the following:
• BCTU provides 16 built-in DTMF receivers; 32 available using the BCTU and BEXU. For five
or more DTMF receivers, appropriate licenses are required. See
page
• BCTU provides 16 built-in Busy Tone (BT) detectors for Auto Busy Redial (ABR); 32
available using the BCTU and BEXU.
• BCTU provides 64 built-in conference circuits; up to 96 conference circuits are available using
the BCTU and BEXU. (See
• 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 internal 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.

Music-on-hold/Background Music Interface

An RCA jack and volume control are built into the processor to interface with a Music-on-hold
and/or Background Music source. With the CIX670, you can have up to 15 MOH/BGM sources by
adding:
• Up to two BIOU circuit cards, each provides three MOH/BGM input sources.
• A BSTU or any analog station card that provides up to eight MOH/BGM input sources.
• MOH/BGM source volume adjustment is controlled by software programming.

Secure Digital (SD) Memory

The BCTU processor has an on-board Secure Digital card slot. A SD flash memory card can be
inserted 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
