Over the years, your personnel have likely acquired a collection of radio technologies, some of which sanction communication over different frequency bands or protocols. This prohibits teams using a variety of radios from coordinating tasks on the ground.
In light of this issue, companies are installing audio bridging solutions that enable personnel with different radio equipment to speak with one another without disruption. As opposed to procuring new equipment to synchronize communications, professionals can simply install the technology at remote sites, enabling them to communicate across the different sections of their system.
This functionality, while helpful, is just the tip of the iceberg in regard to audio bridging’s functionality. In this article, we’ll detail how the technology works and the manner in which it can support your business.
Audio Bridging Supports Dynamic Radio Networks

The Fundamentals of Audio Bridging

Audio bridges use signal processing and controls that enable radios using different frequencies to operate cohesively. Radios depend on repeaters to relay signals over long distances. The audio bridges connect to these devices and switch the audio according to which radios users are trying to communicate with.
The number of repeaters across your operation dictates the number of ports your audio bridge must possess. For example, if your business owns four repeaters, each of which supports a particular communication standard, the audio bridge must have four ports. The connections are known as a bridging matrix, which users can establish either through front-panel DIP switches or via software.
This situation describes cross-banding, which is the primary function audio bridges are typically configured to deliver. However, there are other features from which your radio network can benefit.

Enhancing Operations 

Nowadays, people are using a variety of technologies to share information. The same movement also applies to radio and networking. Accommodating environments comprised of myriad systems has compelled us to manufacture audio bridges that not only execute cross-banding but also support:

  • Rebanding/Narrowbanding: When your organization opts to replace outdated radios, the audio bridges enable you to do so with little-to-no disruption. You can connect the new radios to the audio bridge while allowing the old ones to access the network.
  • Pager linking: Some industries still use pagers to notify employees. Audio bridges support conventional paging gates, allowing radios utilizing different frequencies to connect to the devices. One of our customers used this technology to provide links between P25 frequencies and employee pagers.
  • On-demand network re-configuration: Authorized users can activate several link paths via radio frequencies. For instance, you could allow two regional links to communicate with each other at night, but discontinue the connection during daytime operations.
  • Automatic steering: Audio bridges can reroute communications along different connections if one should fail. As an example, a gold mine created a back-up link via a fiber-optic cable, which the audio bridges could access in the event the facility’s Ethernet link shut down unexpectedly.
  • Fast link keying: One of our models, the 619DSRI, uses a CTCSS fast mode for input signals, implementing a push-to-talk setting before a subsequent CTCSS tone occurs.

The 619DSRI enables system integrators to establish de-centralized, interoperable networks.

There are numerous ways your organization can take advantage of these functions. Government, maritime, supply chain management and other industries have eliminated conventional communication costs after installing audio bridges.

Which model suits your operations? 

There are two audio bridges we offer to organizations throughout the world. The 619DSRI uses firmware and provides system integrators with advanced ways to establish de-centralized, interoperable networks that do not require intervention from central control rooms. Equipped with eight ports, it’s particularly useful for large networks.
The 619EI provides a system configured by front panel DIP switches that is simple to use but very flexible in operation. It has six ports.
