IVX S-Class Product Overview
6
Memory Module
The Memory Module is a CompactFlash
®
card that contains all system programming and configuration data, including
pre-loaded voice prompts. The Memory Module provides voice storage at 64 kilobits/second — the industry's highest-
quality sampling rate. Its voice storage capacity depends on the system’s voice messaging configuration:
• Four-port voice mail — Provides six hours of voice storage.
• Six-port voice mail — Provides 30 hours of voice storage.
Port card
There is only one port card type available for S-Class. The 482 port card is equipped with a standard female Amphenol
connector for easy wiring to a standard 66 or 110 block.
Note: The IVX S-Class Generation II 482 port card cannot be used on any other ESI phone system.
The 482 port card provides circuits to connect up to four loop-start CO lines, eight Digital Feature Phones, and two
analog station ports. The CO line ports support standard CO and Centrex loop-start lines; ground-start CO lines are not
supported. The analog ports provide a standard 24-volt, two-wire connection to fax machines, analog phones, and
modems. Only one analog device can be connected to each analog station port. This card uses ten station ports and
four CO ports when installed.
Note: The system must contain at least one 482 port card to access both conference bridges.
Connections
CO line connection
The IVX S-Class system’s advanced CO line circuitry provides for open loop detection and the system’s built-in Caller ID
interface. The total line capacity is 16 phone lines.
Station connection
Each port card Amphenol connects to station ports. All stations are connected using a single pair. Each port position is
pre-numbered and fixed. Digital Feature Phone station runs can be up to 1,000 feet.
External paging device connection
A dry contact overhead-paging device can be connected to the system through the first port card's 66 block.
System programming
The installer can program the system locally or remotely, through either a phone or one of ESI’s Windows
®
-based
applications — Esi-Access for you and Esi-Admin for the Administrator. Either application runs on a PC-compatible
computer that is connected to the system: (a.) from another location, via the built-in modem; (b.) across the LAN/WAN
via the Network Services Processor (see page 6); or (c.) via a physical link to the system’s RS-232C serial port.
Network Services Processor
The optional Network Services Processor (NSP) interface consists of a dedicated Motorola
®
ColdFire
®
processor and
Ethernet
®
port. The RJ-45 jack provides a 10/100Base-T connection to a site’s LAN.

The IVX S-Class NSP can be
upgraded to support multiple VIP
2
users and ESI TimeLine time and attendance management software. IVX S-Class is
available in two models: with, and without, built-in NSP. An IVX S-Class system purchased without the NSP cannot be
field-upgraded to include this component; therefore, if having an NSP-dependent application (such as VIP) should
become necessary to the customer, the IVX S-Class Base Cabinet must be replaced.
