Small-business system meets your needs — and more
IVX1C-Class is ideal for small businesses. The standard
configuration has a capacity of 3 6 2 — meaning that
it supports three lines, six digital stations, and two analog
ports. For those who need more, the 360 port card (see
“Systems,” page 4) boosts capacity to 6 12 2.
Each configuration boasts the full ESI voice mail feature
set (see “Features at a glance,” below).
Features at a glance
For a small system, IVX C-Class has an impressive
feature set that makes it an attractive choice for a wide
variety of businesses:
• ESI Feature Phones — Compact and stylish, yet
rugged, the 24-Key Digital Feature Phone includes a
high-quality speakerphone, large and informative
multi-functional display and a specially designed key
layout with several dedicated keys to minimize or
eliminate the need to memorize codes. ESI also
offers the 12-Key Digital Feature Phone with similar
design and basic functions (See page 3). At least
one 24-Key Digital Feature Phone must be pur-
chased with each IVX C-Class system.
• Extensive help — ESI’s Verbal User’s Guide uses
spoken and displayed help prompts to help every-
one from the Installer through the Administrator
down to the least experienced end user.
Easily accessible with one press of the HELP key.
You may also go to www.esiusers.com for detailed
on-line help.
• Enhanced Caller ID — Allows one-touch automatic
message return.2
• Call waiting — Includes helpful display, showing
both calls’ Caller ID information, and easy one-key
toggling between calls.

Caller ID service from its telephone service provider.

Features at a glance (continued)
• Conference calling — Includes up to two conference
bridges, and a conference may contain up to four
parties, so the IVX C-Class system can support up to
two conferences of four parties each. Analog phones
on the system also can initiate conferences.1
• Esi-Dex™speed-dialing2— Calls any number using
three separate lists (personal, station, and system);
uses Caller ID information or direct keypad entries
to store numbers.
• Dedicated overhead paging interface — Allows
for external paging through overhead speakers or
multi-zone paging units (amplification required).
• Built-in paging — Without an external paging
system, IVX C-Class provides paging utilizing the
speaker in on-hook Digital Feature Phones.
• 911 alert — Provides immediate line access if any
station dials 9 1 1 to report an emergency; sends a
message via the serial port indicating the start date,
time, station number and end-time of the 911; also
sounds an audible warning at the operator station
and displays, for example:
911 CALL FROM
X102 JOHN JAMES
• Status indicator lamp — Indicates three conditions
of the 24-Key Digital Feature Phone: off-hook,
ringing and new voice mail message.
• Music-on-hold (MOH) — IVX C-Class has an
external MOH port in addition to three prerecorded
MOH tracks.
• Programmable answer ring assignment —
Program incoming calls to ring to an extension,
extension list, or the auto attendantl.
• Day/night mode — Program different answer ring
assignments for day and night.
• Override ring2— Press the programmable override
ring key to suppress ringing on an incoming call. The
call is forwarded to the call-forwarding destination.
• Analog Caller ID — Lets non-ESI analog devices
on the system take advantage of Caller ID.
• Privacy release — Enabling privacy release allows
any system user to conference with an in-progress
call by pressing a CO line key for the line on which
the call is in progress.
1One conference bridge is available on the 3x6x2 main board
only. The second conference bridge is available with
installation of the 360 port card (see “Systems,” page 4).
2Not available on the 12-Key Feature Phone.
Voice mail features
• Two built-in voice mail ports — These are in
addition to the 20 maximum call-processing ports;
thus, you may use the system for its greatest call-
handling advantage without having to balance voice
mail needs versus station capacity.
• Live call recording3— Can record any conversa-
tion or personal memo along with moving or copying
of any recording to other users’ voice mailboxes.
• Highest-grade voice quality (64-kilobit/second
sampling) for voice mail and other storage of voice
messages. IVX C-Class offers two hours of storage.

users’ mailboxes.3

prerecorded and live MOH input, custom MOH can
be recorded on the Memory Module.

and can restore, up to 10 of each mailbox’s most
recently deleted messages.
• Auto attendant — Its eighteen branches let you
and your customer set up a caller-friendly answering
environment, including a company directory. The
auto attendant also features virtually unlimited call
routing, with pager or cell phone notification.
• Automatic day/night mode — Switch from day to
night manually or program the day/night table for the
system to switch automatically.
• Up to 10 departments — Program departments as
“ring-all,” “in-order,” or uniform call distribution (UCD).
• Trunk-to-trunk forwarding — In addition to manual
trunk-to-trunk transfer, trunk-to-trunk forwarding can

auto attendant or enabling off-premises “reach-me”
in a user mailbox.

spoken prompts from ESI’s Verbal User Guide deliver vital call-handling information and are readily understandable by
even a novice ESI phone user. For added reliability, each ESI phone has a sealed membrane below the keys, making it
virtually spill-proof. The sturdy base lets the user adjust each phone four different ways — from near-horizontal to near-
vertical — to fit easily on any desk or counter space.

Systems
At purchase, IVX C-Class consists of a system cabinet with support for three lines, six
digital stations, and two analog ports, along with two voice mail ports, and two hours of
voice mail storage
The wall-mounted system cabinet measures 81/2″W 11″H 3″D, and is designed for
easy installation and easy component access. It houses a Memory Module and main
board, and has an expansion slot for the 360 port card (see “360 port card,” below).
The 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; three CO line interfaces; six
digital station interfaces; two analog ports; a standard RS-232C DB9 serial port; USB port1;
a built-in modem for remote access by ESI technicians; an external paging-device
interface; and an MOH interface
The Memory Module2consists of a CompactFlash®card. It 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 — and two hours of voice storage.
The IVX C-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 six phone lines. 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. A dry contact overhead-paging
device can be connected to the system. The Installer can program the system through a phone.
360 port card
The optional 360 port card3provides support for an additional three CO lines and six digital stations (but no additional
analog ports), boosting IVX C-Class to its maximum 6x12x2 capacity.
