Basic Telephone and Modem Interface 2 (BTMI-2).
The BTMI-2 is a replacement for the BTMI. It
connects telephones and data communications devices
such as autodialers, answering machines, cordless
telephones, facsimile machines, and modems to the
MERLIN II system. A timer may be connected to a
BTMI-2 for automatic answering based on time of day.
Unlike the BTMI, the BTMI-2 does not support
Conference, Drop, or line selection features. It can be
used with MERLIN II systems with Feature Module 1,
Feature Module 2, and Release 3.
●
Basic Telephones.
Basic Touch-Tone telephones,
connected to the MERLIN system with the Off-
Premises Telephone Interface (OPTI) and to outside
telephone lines, provide service to people at a remote
location. On-premises Basic Touch-Tone telephones
can be connected to the system with a Basic Telephone
and Modem Interface 2 or a Basic Telephone Module.

input power to 105-vol~ 30-Hz ringing voltage for
basic telephones connected to the Basic Telephone
Module.
