ordering information.

All variations of the CommLink™ TR6442i Intercom Link work in the same way. The only
difference is in the method in which they are powered and whether they are a 1310mm or a
1550mm unit.
The system provides flexibility in the types of intercom systems that can be used in that the
system can link one type of party line system to another type of party line system, a matrix
frame to two key panels, or act as a two-wire to four wire hybrid adaptor via fiber or as a
standalone local unit. Each of these operating modes is explained in detail later in this
document.
TWO-WIRE PARTYLINE MODE
Plug two channels of Clear-Com® PL (two XLRs) or RTS® TW (one XLR) into each CommLink
module and connect them with a fiber cable. The system will "translate" between two
systems so that you can have Clear-Com® at one end and RTS® at the other. It also translates
the call lights.
