TORRANCE, Calif.--June 4, 1998--Underscoring its South American marketing drive, Telemobile Inc., a leading international provider of telecommunications systems for established and emerging nations, has launched its first emergency "Callbox" wireless telephone system in Chile.

The new Roadside Emergency Telephone, designated the RET system, is for use on public highways or private toll roads and can service remote areas where cellular systems are not commercially feasible, announced Dan Thomas, vice president of marketing.

Installation began June 3, with completion scheduled for June 15. Telemobile's Emergency Callbox project is supported in Chile through CDS Engineering of Santiago. The first phase of the Chilean wireless system includes 26 Callboxes, two repeaters and a command center that covers more than 75 kilometers of toll road.

Each full-duplex wireless Callbox, when activated, pinpoints the location and allows the center operator to dispatch emergency highway services such as fire, police, mechanical assistance, or medical help as needed.

"Telemobile's systems were put through rigorous environmental testing at ISO 9001 labs, similar to the Lucent Technology / Saudi Arabian US$15 million project announced last month," Thomas said. "Performance and reliability are designed to meet the ITU global standards. Telemobile has designed-in self-testing and health-check monitoring of the Callbox emergency roadside phone systems," Thomas explained.

Telemobile Inc now offers a complete line of "customizable" emergency Callbox radio telephones. The Telemobile Saudi Emergency Call Box project is supported through Lucent Technology, the primary contractor with the Saudi government for various telecommunications projects in The Kingdom of Saudi Arabia in addition to this country wide Call Box System. The Ministry of Public Transportation (MOPT) in Saudi Arabia system is planned in stages. The first phase is planned to be online and providing service this summer.

Telemobile's search and report software program performs a periodic validation to assure the emergency phones are in working order. Also as a safety measure, an alarm system can be installed that notifies the command call center of any Callbox tampering or malfunction.

These high-quality, low-cost systems have a wide variety of options available including wireless caller ID, pay phone signaling, and voice scrambling modules. Telemobile's all-digital network systems are also available using Telemobile's TDMA technology for high speed data transfer as well as low-cost integrated multiplexer for a combination of voice, fax and wireless Internet services anywhere in the world.
