AT&T Enhances Interoperability for Public Sector and Public Safety Networks

AT&T announced Inter-RF Subsystem Interface (ISSI), an IP-based, open-standard connection – APCO Project 25 (P25) for connectivity among public sector and public safety networks.
AT&T already supports CSSI lets customers connect dispatch console systems.

AT&T said public safety customers can connect their LMR networks to AT&T Enhanced Push-to-Talk to extend coverage and communications nationwide. AT&T Enhanced Push-to-Talk also meets the requirements of the Federal Information Processing Standard (FIPS) Publication 140-2. FIPS is a U.S. government computer security standard used to test and validate product security.

The end-to-end solution also integrates AT&T Dynamic Traffic Management to provide priority call treatment and network access based on Quality of Service network technology.

“With ISSI, the geographic and technological restrictions of LMR are a thing of the past,” said Walt Rivenbark, associate vice president of Advanced Mobile Solutions, AT&T. “We’re the first major U.S. wireless carrier to offer ISSI and CSSI connectivity to more than 2,500 public safety networks.”
