IVX 20 General description
A.1
General description
IVX 20 (IVX stands for I ntegrated V oice E x change, while the 20 indicates the system’s maximum
number of call-processing ports) is an advanced business telecommunications system for small
offices. It includes not only phone service but also voice mail, an automated attendant 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 transformer powers the system.
Programming of the system can be done locally or remotely
1
through either the phone or the
Windows
®
95/98-based Esi-Access program (on a PC-compatible computer which has either dialed
into the system from another location or is physically connected to its RS-232C serial port).
Telephone system features
IVX 20 expands from its basic four-line, eight-station configuration to a six-line, twelve-station
configuration. For offices with more extensive telecommunications needs, IVX 20
migrates to the
more fully featured IVX 128 system.

compliant with Basic Telephony Service.)

any Digital Feature Phones already installed, minimizing the need to retrain employees).
