Introduction
INTRODUCTION
Each Inter-Tel Axxess hardware cabinet houses a power supply unit and up to seven circuit
cards. Together, the circuit cards perform the switching activities for the system, detect incom-
ing calls, process data-controlled features, and control the interaction of station instruments,
trunks, intercom calls, and voice processing system applications.
For increased port capacity, two, three, or four cabinets may be connected together to form one
expanded cabinet. For maximum capacity, up to four dual-cabinet systems can be connected
with an Asynchronous Transfer Mode (ATM) Switch, creating an eight-cabinet system.
The actual number of endpoints and lines available depends on the number and type of cards
and stations installed on the system. For example, there could be as many as 512 outside lines,
448 Inter-Tel endpoints, or 512 single-line sets, depending on the circuit card configuration.
The circuitry and software in the each cabinet combine to produce an “integrated switching
matrix” of 128 time slots (voice channels). A four-cabinet system has 512 time slots.
With system software version 5.0 and later, you can connect two or more systems to form a
network that provides a seamless interface between the systems. To the user, the network
appears as though it is one integrated system. With few exceptions, the user can perform all of
the functions across the network that can be performed on a single system.
Standard system hardware features include:
•
A Central Processing Unit (CPU) Card for storing the system software programs, the
customer’s database, and call processing history files.
•
Light-emitting diode (LED) indicators for showing main processor operation, database
error occurrences, minor system alarms, and database back-up battery connection.
•
External ports for connecting a personal computer (PC) or modem to program the sys-
tem database and/or for connecting output devices for the Station Message Detail
Recording (SMDR) and programming reports. Ports are also provided for the voice pro-
cessing system interface.
•
Database back-up battery for preserving the system database in the event of a power
failure.
•
Reset switch to manually reset the system during troubleshooting.
•
Easily accessible voltage test points for checking the system operating voltages.
•
Relays for connecting power failure transfer equipment.
•
Circuitry for connecting an external music source (radio, tape player, etc.).
