Your authorized AT&T representative can advise you if you need any of these
accessories for your installation. Some accessories have special operating
instructions as follows:
Basic Telephones
On-premises basic Touch-Tone telephones can be connected to station jacks
on a 12-Basic Telephone (012) Module. People with these basic telephones
can use many of the features of the MERLIN II system by using dial codes
and switchhook flashes. On-premises basic Touch-Tone telephones can also
be connected to the system with a Basic Telephone and Modem Interface 2
(BTMI-2). The BTMI-2 makes it possible to connect basic telephones and most
other types of telephones and data devices to analog station jacks on the
MERLIN II system control unit.
NOTE:
A Frequency Generator must be installed in the Power Supply
Module to use basic telephones with the MERLIN II system.
To provide service to people at a remote location, off-premises basic Touch-
Tone telephones can be connected to the MERLIN II system through outside
lines with the Off-Premise Telephone Interface (OPTI). The OPTI permits you
to use an off-premises telephone to access many of the features of your on-
premises communication system using dial codes and switchhook flashes.
