Zetron Telecommunications Industry Assoc P25 console subsystem interface

The open-standards Telecommunications Industry Association P25 console subsystem interface that supports digital connectivity between the company’s communications system (ACOM) and trunked P25 networks is a fully digital switching and multiplexing dispatch system that integrates voice (radio and telephone), data, paging and video. CSSI further enhances its interoperability.

Through CSSI and its other P25 interfaces, Acom can meet or exceed the most stringent security requirements including support of federal information processing standard 140-2-compliant digital encryption.

As systems that use CSSI can work together without requiring proprietary interface protocols, they give users more choice in their selection of dispatch console systems and radios.

CSSI complements the company’s previously released DFSI (digital fixed station interface), which enables digital communications between Acom consoles and conventional P25 networks that are operating with either an analog FM or P25 common air interface.

The Acom system allows interoperability across a wide spectrum of radio bands and dissimilar communications interfaces such as P25, OpenSky, iDEN, TETRA, EDACS, SMARTNET, SmartZone, MPT 1327 and LTR. Acom’s distributed network architecture allows operation and resource sharing of voice, video and data between control centres separated by hundreds, sometimes thousands of kilometres.

The system has the flexibility to handle both established and emerging communications technologies such as VoIP and LAN/WAN, and is scalable from small, two-person dispatch facilities to operations centres with hundreds of operator positions.
