To set the MODE switch for call waiting, slide the switch to VOICE (the
left position). Call waiting may be used in any telephone set installation
described in this document unless you have connected a data device,
such as a modem, to the BTMI-2. To place and answer calls, refer to
the section of this document titled “User Instructions for the BTMI-2.”
NOTE: The normal MODE switch settings are VOICE and DATA. The
rightmost position, TRANS, is not used at present and is intended for a
future MERLIN Communications System release.
System administration for a basic telephone connected with a BTMI-2
cannot be performed after the BTMI-2 is connected. To program
features for your basic telephone(s) connected to the BTMI-2, you can
use Centralized Programming or, before you connect the BTMI-2, con-
nect a voice terminal directly to the control station jack to which you plan
to connect the BTMI-2, and program from there. For further information
refer to the section of this document titled “Administration and Program-
ming for the BTMI-2.”
Installation
The BTMI-2 may be used with the following equipment:
●
●
●
●
One telephone or data device
Two telephones and/or data devices
A timer and a transformer for timer-controlled operation
This connection turns the BTMI-2 ringing generator on and off
automatically. This connection may be used with the other telephone
installations described in this section.
Two MERLIN Communications Systems
Two MERLIN Communications Systems can be connected using one
or two BTMI-2s.
A two-system connection using one BTMI-2 provides one system
with access to the second system’s intercom numbers and outside
lines (full direct access). The second system can access intercom
numbers on the first system, but must be transferred (limited
access).
A two-system connection using two BTMI-2 provides both systems
with full direct access to each other’s intercom numbers and outside
lines.
NOTE: If you have a Model 1030 or 3070 with Feature Module 5, do not
connect the BTMI-2 to a voice terminal jack that is used for an attendant
position (e.g., receptionist or secretary).
