MSV Announces a New JPS Cross-Band Interface, Enabling More Public Safety Agencies to Access MSV's Dispatch Radio Network

Reston, Virginia, UNITED STATES

MONTREAL, Aug. 10, 2004 (PRIMEZONE) -- Mobile Satellite Ventures (MSV) announced during the Association of Public Safety Communications Officials (APCO) Annual Conference that it has expanded its dispatch radio network to include a cross-band interface from Raytheon JPS Communications.

The JPS ACU-1000, a proven interface on terrestrial radio networks, will now operate over MSV's two-way satellite dispatch radio network. The interface will provide emergency responders the ability to instantly communicate with their command units and to each other when responding to an emergency outside the normal coverage area. "This enhancement will greatly facilitate interagency communications among key federal and state users of MSV's dispatch radio service, while enabling non-participating agencies to gain access to our network during emergency-response situations," says Austin Comerton, channel manager for MSV.

The ACU-1000 enables disparate audio devices to communicate with each other without replacing current investments and infrastructure. Agencies on the scene of an emergency that need to tie into an MSV talkgroup can simply plug their base station into a JPS unit connected to an MSV terminal. "The ability to interface with MSV's satellite dispatch system represents a substantial increase in communications capabilities for first responders. The combined MSV and JPS technologies have markedly increased the scope of interoperability coverage," said Jeff Critser, vice president and general manager of Raytheon JPS Communications. MSV has the only dispatch radio network that provides coverage across North America and allows for multiple public safety agencies to communicate over a single, secure channel.
