1. INTRODUCTION
2. SYSTEM CAPACITIES
1.1 The 256
System is a state-of-the-art, digital, voi-
ce/data, hybrid telephone system. As a hybrid system, it
incorporates many of the
features of key
systems with many of the expanded features and flexi-
bility of private branch exchange
systems.
1.2
The
System is designed to meet the needs of
growing businesses.
fact, the system’s unique struc-
ture (including digital signal processing) allows it to be
easily adapted and expanded as business communica-
tion needs change. The modular design makes the sys-
tem easy to install and service. And, the programmable
features provide an abundance of user-friendly applica-
tions to meet each customer’s needs. Highlights of the
system’s design include:
Advanced microprocessor technology.
Modular, easily replace-able hardware with add-on
capabilities for optional features.
Flexible programming to customize many system
and station features.

The equipment cabinet has 16 slots for station and
trunk cards.

2.2
For example, if all 16 cards are station cards, there
can be a maximum of
station instruments installed.
Or, if only one of the cards is a type of
Card (re-
quired), four are
Cards (the maximum allowed), and
the other 11 are Loop/Ground Start Cards, the system
maximum is 16 stations (using digital
or using
AIM
which can be installed two to a
circuit) and 184 trunks. Of course, in most circum-
stances, the maximums listed below will never be
reached due to the variety of cards and station instru-
ments installed.
2 3
A fully-equipped
System has the capacity for
up to:
Ports (16 available card slots with a maxi-
mum 16 circuits per card equals 256 ports.
Although it is theoretically possible to equip
more than
ports [e.g., using
Cards and/or
digital or
AIM keysets], the system
limits the number to 256. See page 2-6 for more
information.)
