Project 25 Inter RF Subsystem Interface (ISSI) provides a wireline interface for connecting multiple P25 systems together. This will allow users to roam onto other P25 systems providing network of network interoperability.
The ISSI.1 Network gateway is Motorola’s first ISSI product and is designed to the P25 TIA-102 standards documents and based on results from extensive customer research and feedback. It will be available in the fourth quarter of 2009. Motorola’s ISSI.1 product offers the following features:
ISSI Encrypted and Non-Encrypted Group Call
ISSI Emergency Call
The ISSI.1 Network Gateway solution also enables different system’s console operators to communicate on intersystem ISSI group calls.
The P25 ISSI is a “wireline”, network IP-based solution which builds upon today’s P25 over the air “Common Air Interface” (CAI). A key advantage of wireline interoperability solutions is that systems of different System IDs, different user databases and of different RF Bands can be interconnected. Wireline solutions keep the traffic digitally vocoded and encrypted for greater performance and security. It allows public safety agencies to: Utilize the coverage areas of existing connected networks, which might span thousands of square miles. Maintain secure, encrypted traffic across the networks. Roam on to connected networks and still communicate with home dispatcher.
Motorola is committed to the Project 25 standards process. We are proud of our history of leadership in delivering standards based solutions such as Project 25. Motorola’s public safety product portfolio has been based on Public safety standards and we have helped customers around the world benefit from the standard for mission critical interoperable communications.
