Company's P25 Portable Radios Used in Cisco Booth to Demo the Interoperability of Cisco’s IPICS System
Irving, TX – September 6, 2007 – EFJ, Inc. (NASDAQ: EFJI) announced that its EFJohnson subsidiary has taken part in a milestone in wireline interoperability by participating in the Project 25 Inter RF-Subsystem Interface (ISSI) Group Call using the new Project 25 ISSI standard during the Association of Public-Safety Communications Officials (APCO) International’s 73rd Annual Conference & Exposition in Baltimore. The company was involved in other demonstrations of interoperability at the conference.
"The demonstration was a milestone in wireline interoperability," said Michael E. Jalbert, chairman and chief executive officer of EFJ, Inc. "EFJohnson is one of four Project 25 compliant infrastructure system suppliers involved in the demonstration. Each vendor placed a call on a different frequency band. Our radios clearly talked through the infrastructure of the other suppliers, and vice verse. In addition, our portable radios were used in the Cisco booth to demonstrate interoperability on the exciting Cisco IPICS system. And as longtime members of the Project 25 Technology Interest Group (PTIG), we provide equipment and staff for their booth at major industry conferences."
