IVX 128 General description
A.1
General description
IVX 128 (IVX stands for Integrated Voice Exchange, while 128 indicates the system’s maximum
number of call-processing ports) is an advanced business telecommunications system that includes
not only phone service but also voice mail, an automated attendant, automatic call distributor
(ACD) and computer integration. The system itself 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 128 expands from its basic six-line, twelve-station configuration to handle as many as 66 CO
lines. For offices with higher-bandwidth needs, T1 support is also available through the installation
of one or two T112 cards.
• Impressive expansion capability — Handles up to 66 CO lines and up to 84 stations.
• T1 support — Can connect to higher-bandwidth lines, which more and more offices use.
• Digital Feature Phone — Compact, rugged design; includes a high-quality speakerphone, large
and informative multi-functional display, and a specially designed key layout with several dedi-
cated keys to minimize or eliminate the need to memorize codes. (A TAPI model is available; it’s
compliant with Basic Telephony Service.)
• Extensive help — Verbal User Guide
™
uses spoken and displayed help prompts to help everyone
from the Administrator down to the least experienced end user. Easily accessible with one press
of PROG/HELP.
• Enhanced Caller ID — Allows one-touch automatic message return.

• Live call recording — Can record any conversation or personal memo, with moving or copying of
any recording to another user’s voice mailbox (see “Voice mail features,” below).
• Call waiting — Includes helpful display, showing both calls’ Caller ID information, and easy one-
key toggling between calls.
• Conference calling — Includes 24 conference bridges, and a conference may contain up to four
parties, so IVX 128 can support six conferences of four parties each or eight conferences of three
parties each.

• Esi-Dex
™
speed-dialing — Calls any number from three separate lists (personal, station and
system); uses Caller ID
1
information or direct keypad entries.
• Dedicated overhead paging interface — Allows for paging through an external paging system
(requires amplification).
• 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

This and all other references to Caller ID service within this manual assume the end-user organization subscribes to
Caller ID service from its telephone service provider.

Of course, IVX 128 also supports any combination that does not exceed 24 parties and does not exceed four parties in
any conference —
e. g., four three-party conferences and three four-party conferences.
