AT&T supports ISSI, CSSI, PTT

AT&T in the US has announced that it now supports Inter RF Subsystem Interface (ISSI) for P25. Earlier this year, the company announced support for CSSI, which lets customers connect dispatch console systems.

Customers can connect their LMR networks to AT&T Enhanced Push-to-Talk to extend coverage and communications across the USA. AT&T Enhanced Push-to-Talk meets the requirements of the Federal Information Processing Standard (FIPS) Publication 140-2, a US 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 US wireless carrier to offer ISSI and CSSI connectivity to more than 2500 public safety networks.

“We expect this solution to change how public entities think about their radio services. They can now communicate virtually whenever, wherever they need to. And the solution complements their existing systems with Enhanced Push-to-Talk’s cost-effective and user-friendly functionality,” added Rivenbark.

AS&T is piloting ISSI with several customers, including the city of Richardson in Texas, which is deploying LMR-interoperable EPTT devices to its mission support teams.
