IVX C-Class Installation Manual

General description

®
Welcome to IVX C-Class (IVX stands for Integrated Voice Exchange). It offers the small business an
all-in-one phone system including not only phone service but also ESI's Integrated Answering Machine
— which allows up to two people to leave messages simultaneously and accepts a total of 30 minutes of
voice message storage.

The IVX C-Class system is housed in a surprisingly small case that is wall-mounted in the telephone
equipment room. An external, wall-mounted power transformer powers the system.

Telephone system features

IVX C-Class is configured to accept six lines, 12 digital stations, and two analog devices.
• Impressive capacity — Handles six CO lines and up to 12 stations.
• 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 B.1).
At least one 24-Key Digital Feature Phone must be purchased with each C-Class system.
• Extensive help — ESI's Verbal User Guide
everyone from the Installer through the Administrator down to the least experienced end user.
Easily accessible with one press of the PROG/HELP key. You may also go to www.esiusers.com
for detailed online help.
• Intelligent Caller ID — Allows one-touch automatic message return.
• Call waiting — Includes helpful display, showing both calls' Caller ID information, and easy one-key
toggling between calls.
• Conference calling — Includes two conference bridges, and a conference may contain up to four
parties, so IVX C-Class can support two conferences of four parties each. Analog phones on the
system also may be parts of conferences.

• Esi-Dex speed-dialing — Calls any number using three separate lists (personal, station, and
system); uses Caller ID information or direct keypad entries.
• Dedicated overhead paging interface — Allows for external paging through overhead speakers or
multi-zone paging units (amplification required).
• 911 alert — Provides immediate line access if any station with line access 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 a warning tone 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.
