The DMRX Core was a pair of redundant cBridge devices dedicated to transporting talkgroups to and from other cBridges which provide connectivity to repeaters. The goal was 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.
Opinions of the masses posted on Facebook and Groups.io that their view of DMRx is no longer an effective resource for distributing TalkGroups and called for re-engineering.
I was suprised that before a constructive request to increase the server resources or bandwidth that the community expressed interest in re-engineering a replacement for DMRx. It turns out that effort became our exit from serving the DMR community.
After 6 years of serving the DMR Community it was time to get out of the way of those whom desire to replace DMRx, the DMRx admin decided to contribute to the re-engineering effort by getting out of the way. A planned Shutdown was announced.
After midnight on the 2nd of May, 2020 DMRx servers stopped providing connectivity to Talkgroup sources. It appears that the re-engineering effort is sucessful as there is little or no traffic on the DMRx Network.
There are a few lingering connections that their C-Bridge administrators will need to redirect to the new re-engineered sources.
It had been fun, it had been alot of work, it had been a considerable investment and it has benefited untold thousands of amateur radio operators over the last six years. Best of all are the relationships that were made to last longer than DMRx would.
