The DMRX Core is a pair of redundant cBridge devices dedicated to transporting talkgroups to and from other cBridges which provide connectivity to repeaters. The goal of the core is to ensure that a simple hardware or software failure does not cause a large disconnect between systems and to provide the most efficient path between endpoints which reduces the occurrence of call collisions and such.

Currently Available Talkgroups

These are the talkgroups available on the DMRX Core and their associated configuration parameters. If you have a talkgroup that needs reliable wide area distribution, please contact us and let us know how we can help.
