22 LINGO TECHNICIAN’S GUIDE
Telephone system requirements
Preparing your customer’s telephone
system to support Lingo is straightforward.
To complete this step, you must know how
to program the telephone to work with
voice mail. The Telephone System Guide
provides some programming details for
many telephone systems.
After ensuring that the customer’s tele-
phone system meets Lingo’s requirements,
follow the instructions in “Preparing the
telephone system” and “Testing the single-
line ports” later in this chapter, before
connecting Lingo to the telephone system.
General telephone system
requirements
The telephone system must be equipped to
support single-line telephones. Each Lingo
port connects and operates as a single-line
telephone. A two-port system needs two,
single-line telephone connections, and a
four-port system needs four connections
on the telephone system.
The single-line connection points on the
telephone system are also called ports. In
other words, a Lingo port connects to a
single-line telephone port on the tele-
phone system.
