OPERATING A TW-60
INTRODUCTION
Thank you for choosing this Clear-Com product.
“Radio interoperability” is the ability of public safety providers – law
enforcement, firefighters, EMS, emergency management, public utilities,
transportation and other personnel – to exchange voice communications on
demand, in real time. It is the term that describes how radio communications
systems should operate between and among agencies and jurisdictions that
respond to common emergencies. Communication should be achieved regardless
of the brands, model numbers, or frequency ranges of the radio equipment used.
The TW-60, in conjunction with an associated Clear-Com matrix
communications system, can be installed with an existing Land Mobile Radio
communications system to provide interoperability.
Please read this manual completely to better understand the functions of the
TW-60. This manual is to be used in conjunction with the manuals supplied for
the associated Clear-Com matrix communications system. For questions not
addressed in this manual, contact your dealer, distributor, or Clear-Com directly.
Our applications support and service people are ready to help.
DESCRIPTION
The TW-60 Public Safety Radio Interface provides the physical interface point to
connect a Land Mobile Radio to a Clear-Com matrix communications system. It
provides the necessary control and voice connections, including the ability to
delay the retransmission of voice to allow for the key up time on the
retransmitting radio. Each 1RU TW-60 provides and powers four separate radio
interface channels.
