Strata CTX Configuration

Large-scale Integrated (LSI) circuits

The processor has built-in LSI circuits that support the following:
16 built-in DTMF receivers
16 built-in Busy Tone (BT) detectors for Auto Busy Redial (ABR)
64 conference circuits for up to eight party conferences. Up to 96 conference circuits are available
using the BEXS. A built-in, adjustable, digital Pad technology that allows audio volume to be
adjusted 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
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 CTX670, you can have up to 15 MOH/BGM sources 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 card slot. A SmartMedia 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.

Network Interface

The processor has an on-board Ethernet 10base-T Ethernet circuit for connection to Open Architecture
Computer Telephony Interface (CTI) applications. This provides extensive call control and telephone
support for CTI applications. The Ethernet Network Interface Card (NIC) port also enables connection
to the following:
CTX Attendant Console
ACD server
Local and Remote CTX WinAdmin PC
Soft Key Control of Voice Mail features

Maintenance Modem

A built-in maintenance modem (33.6Kbps/V.34) on the processor can provide point-to-point local or
remote connection to the CTX WinAdmin administration software.
