CONNECTING TWO MERLIN COMMUNICATIONS SYSTEMS
You can connect two MERLIN Communications Systems using the
BTMI-2. There are two possible installations.
If you connect two systems using one BTMI-2, one system has full direct
access to outside lines administered to the BTMI-2’s station jack and
intercom numbers of the second system. The second system has
access to the first system’s intercom numbers as an incoming line
appearance, e.g., a call from the second system to the first system is
handled like an outside call and can be transferred.
NOTE: To enhance access to your system’s lines with this type of instal-
lation:

If you have a MERLIN II system with Feature Module 2; use the
Direct Inward System Access (DISA) feature. Refer to your MERLIN
II Communications System with Feature Module 2 System Manual for
further information.
If you have a MERLIN Plus Communications System Release 2, use
the Direct Extension Dialing (DXD) feature. Refer to your MERLIN
Plus Communications System Release 2 System Manual for further
information.
You can connect two communications systems using two BTMI-2s, giv-
ing both systems full direct access to each other’s outside lines and
intercom numbers. Each installation is explained in the following para-
graphs.
Connecting Two Communications Systems Using One BTMI-2 (Full
Direct Access on One System and Limited Access on the Other)
For this installation you need one BTMI-2, a 4-pair modular cord (pro-
vided) and a 2-pair modular cord (not provided).
NOTE: In this section, the communications systems are referred to as
System A and System B. When connected, System B will have full
direct access, System A will have limited access.

Plug one end of the 4-pair modular cord into a voice terminal jack on
the System A control unit (Figure 6). (Note the station number for this
jack. A person on System A will have to use this intercom number to
access System B.)
Plug the other end of the cord into the jack labeled LINE on the
BTMI-2.
Plug one end of the 2-pair modular cord into a line jack on the Sys-
tem B control unit.
NOTE: This line now represents the BTMI-2 and should be admin-
istered with DISA or DXD as previously mentioned.
