DMR was designed for the commercial and government world, and with the next generation of DMR hitting the market, the older generation equipment is flooding the secondary market and being snapped up by Hams.

+ | === Wide Network === | ||
+ | This is the flavor of the DMR system. There are three different flavors, DMR-MARC, DMRplus (DMR+), DCI, and BrandMeister. The architecture of each is a little bit different. We track the Wide Network because it influences the architecture of a client-radio codeplug. | ||
+ | |||
+ | === Local Network === | ||
+ | A local network is a group of repeaters that have very similar talk groups. They tend to be linked to each other through the talk groups in various ways and connect to the same c-bridge. | ||
+ | |||
+ | === c-Bridge === | ||
+ | This is like a server. The Local Networks connect to the c-bridge which handles the routing of talk groups. The c-bridge can route talk groups to other repeaters within the same local network or send it out to other c-bridges or even cross over to other Wide Networks. | ||
==== Editing a Repeater' | ==== Editing a Repeater' | ||
- | When editing | + | First of all, you need to understand what a talk group is and why DMR repeaters use them. Talk groups are not just used on DMR repeaters, but also exist on P-25 and other repeater |
- | From this window, you have two options. One is to Add a Network and the other is to Add a Talk group. | + | Since DMR repeaters are typically linked |
+ | So, another caveat to the talk groups is the full-time vs. PTT monitoring. Repeaters have the option of monitoring and repeating all traffic for a talk group all the time. Usually, owners will program a talk group to only be monitored when a user requests it. This can really cut down on the chatter and is a common setting for very large area talk groups, like the Worldwide talk group. For a user to use that channel, they bring up that talk group on their radio and key the radio. This will send a message to the repeater to begin actively monitoring that talk group. This is the same in concept to dialing up an AllStar room, IRLP node, EchoLink node, etc. The repeaters are also set up with a hold off timer which is how long the repeater will listed to that talk group without hearing a local key up. Repeaterbook does not track hold off timers. | ||
+ | |||
+ | The final caveat to a talk group is the time slot the talk group is on. DMR repeaters can actually handle two conversations at once, one on time slot one and one on time slot two. This concept would seem impossible for users of analog repeaters because doubling would occur. However, DMR repeaters can " | ||
+ | |||
+ | So, to add a talk group to a repeater, you need, at minimum, the time slot and the talk group. You can enter the talk group info without the access (full-time vs. PTT), but users appreciate this information. With this data, you can edit a repeater from the " | ||
+ | |||
+ | From the new window that appears, you have three options. One is to Add a Network, Add a Single Talk group, or Bulk Add. You should add the Network (c-bridge) if you know what it is. | ||
