IVX E-Class Product Overview

System components

IVX E-Class cabinet components consist

of:

Base Cabinet I •

–

Main board

– Memory Module

– Two port card slots

– External wall-mounted transformer

• Base Cabinet II (optional)

–

Expansion board

– External wall-mounted transformer

– Two port card slots

–

Available only for IVX 128e

Expansion Cabinet (optional) •

–

Two port card slots

–

Up to two of these can be placed

in a system (one per each Base

Cabinet I or II)

Each system, IVX 72e or IVX 128e, consists of a Base Cabinet I. IVX 72e

can accept one Expansion Cabinet to support up to four port cards; IVX

128e can accept one Expansion Cabinet, then a Base Cabinet II and a

second Expansion Cabinet to support up to seven port cards. The wall-

mounted Base Cabinet I is designed for easy installation and easy

component access. It houses the Memory Module and Main Board, one

multi-purpose serial port, a MOH connector and two port card slots (see

“Port card options,” page 9). The Base Cabinet I can support one

Expansion Cabinet, for a potential total of four port cards.

To expand an IVX 128e system beyond the Base Cabinet I (and its

Expansion Cabinet), connect a Base Cabinet II via ribbon cable to the Base

Cabinet I. The Base Cabinet II houses up to two port cards; it can also

support one Expansion Cabinet. You can “piggy-back” an Expansion

Cabinet to the front of each IVX E-Class Base Cabinet. Each Expansion

Cabinet houses up to two additional port cards each, enabling the system

to grow to its maximum configuration — four port cards on IVX 72e, or seven port cards on IVX 128e.

Main board

The IVX E-Class main board combines leading-edge hardware components — including a Motorola

ColdFire

processor and DSP structure — along with proprietary operating system software. The board

provides: system control of the Memory Module and port cards; a standard RS-232C DB9 serial port; a

built-in 33.6 Kbs modem for remote access; an external paging-device interface; an MOH interface; and

support for the optional NSP.

Memory Module

The Memory Module — a hard disk drive with improved performance — contains all system programming

and configuration data, and pre-loaded voice prompts. The Memory Module provides 70 hours (IVX 72e) or

280 hours (IVX 128e) of voice storage at 64 kilobits/second — the industry's highest-quality sampling rate.

The Memory Module and port cards are packaged separately and are mounted in the cabinet during installation.
