P25 Digital and Analog Interoperability, All in One Box.

The DRB-25 is a compact base station/repeater unit, fully compatible with the APCO Project 25 (P25) standard of secure digital radio. Its high power, features and flexibility make it an ideal building block for conventional radio networks.

The DRB-25 supports simultaneous analog and digital P25 operation. Its crossband feature permits communication across different bands as well, making the DRB-25 a highly cost effective migration to digital radio.

Applications

The DRB-25’s modular design and software based features make it an extremely flexible building block for a wide range of network applications.

The DRB-25 can operate in a stand-alone mode or within a conventional network using remote repeaters.

Its compatibility with P25 means that it is ideal for use by public safety organizations requiring a high level of security and interoperability, as well as public utilities (such as power companies) and transport organizations (such as railways).

Available in both VHF and UHF bands the DRB-25 can easily be implemented in a wide range of situations. Interconnection to the PSTN or a microwave bearer is available through a standard 2-wire or 4-wire + E&M interface.

The DRB-25’s compact dual radio configuration is a very cost effective solution for remote locations. One channel can be used as a base station or repeater for general communications, while the second channel acts as a link to other base stations or repeaters.

Fully Software Controlled

The DRB-25’s modular design means there’s no field tuning, adjustments, or alignments necessary. Once the unit is set to your specifications, any future changes are a simple hot-swap of the appropriate module.

Built-in PC Web Server

Control / monitor your system remotely via a built-in ethernet port. Watch critical user info, analyze system activity, transmit, receive, perform diagnostics, monitor NAC activity, change channels, view signal levels, and more, all from a PC Web browser

Linking Flexibility

The DRB-25 may be configured with one or two independent channels. Each channel may operate as an analog and/or a P25 digital repeater or may also be programmed to autosense the mode of a received signal and thus be shared between analog and digital users. With built-in P25 vocoding and DES encryption the DRB-25 may be connected directly to existing tone-based remote and console equipment using 2W and 4W E/M circuits. Direct connection to 2W telephone lines for analog and P25 digital calls is also supported. “IP enabled” connection to corporate intranets and public internets and providing VoIP and control, monitoring and diagnostics through and built-in Web server.

Link Different Modes

Applicable during a migration to digital operation or for interoperablity or to provide interoperability between analog and digital users operating in the same geographic area. The users may be operating in different frequency bands.

Link Wide Areas

Two DRB-25s each configured with 2 channels may be used in either analog or digital mode to provide coverage over a wider area. The coverage and linking channels may use different bands. The DRB-25s are transparent to CTSS/CDCSS and P25 signaling.
