Catalyst Demos P25, DMR Features in Consoles (8/16/12)
Catalyst Communications Technologies plans to demonstrate Project 25 (P25) and Digital Mobile Radio (DMR) capabilities at the Association of Public-Safety Communications Officials (APCO) International exhibition.

Catalyst will demonstrate its voice dispatch console with Tait Communications and Harris using P25 standards. Catalyst will show two different interfaces between its dispatch and interoperability solutions with P25, the Digital Fixed Station Interface (DFSI) and the Common Air Interface (CAI).

Catalyst authenticated its compatibility with the Tait TB9100 base station via the P25 DFSI standard, TIA-102.BAHA. The demonstration will show P25 messages including unit identification and emergency passing from P25 subscriber units to the Catalyst IP|Console. Attendees will also see how unit IDs are automatically converted to aliases and how the console digitally controls functions on the base station like channel selection. Earlier this year, Catalyst exhibited its P25 DFSI interface with the Daniels Electronics MT-4 base station.

Catalyst also will introduce its Propulsion Console, demonstrating voice calling and messaging on a graphics-rich critical communications dispatch console. The Propulsion demonstration will include control of P25, MDC-1200 and Verizon Wireless push-to-talk (PTT) capabilities.

The console provides interoperability between DMR and the other radios by using graphical controls. Propulsion also supports a variety of advanced signaling, including unit ID and channel change for these other systems. The DMR portion of the demonstration will use Harris Momentum radios, and Catalyst is a Harris Momentum applications partner.

“As more public safety and other critical communications agencies comply with the FCC’s narrowbanding requirements, the implementation of DMR accelerates,” said Catalyst president Robin Grier. “These agencies are able to cost effectively upgrade their dispatch consoles as part of the narrowbanding project, reduce training costs, and add powerful new capabilities like integrated text messaging.”
