Audio Bridges


Audio bridges provide a means of creating a wide variety of network connections to facilitate interoperability across frequency bands, making sure your organization can communicate efficiently.

Cross-banding disparate radios

Increasing interoperability is the core application of audio bridges. Connecting multi-site networks, whether they carry equipment from different manufacturers or on different frequency bands, is the most common usage scenario. Radios in any band are able to be interconnected, including HF, VHF, UHF, Airband, Marineband, P25 and Trunked.*

Rebanding and narrowbanding 

Many organizations have faced challenges with new regulations requiring the rebanding of radios onto a narrower frequency. Using an audio bridge simplifies this process, allowing you to install new equipment over a period of time rather than all at once. The audio bridge lets new and legacy units run in parallel, meaning there’s no downtime in the changeover.

Network reconfiguration on demand

Some radio networks require reconfiguration, however traditionally the process has been somewhat complicated. With an audio bridge, it’s possible to preconfigure various link paths that can easily be activated over an RF link or IP network.

Linking pagers to modern radio protocols 

While they may not be as common as they once were, in some organizations pagers are still a popular and efficient means of communication. Interoperability with modern radio technologies isn’t assured with the ageing devices, but an audio bridge can connect them easily.

Automatic steering 

Audio bridges can be configured to re-route incoming transmissions based on a defined event. For example, in hazardous environments where a failed network could present a significant danger, audio bridges can automatically steer communications to a backup system.

Fast link keying

Designed to eliminate long delays in CTCSS-controlled multi-hop links, a fast CTCSS mode is incorporated into the 619DSRI for input signals.
