Re: PTT Configuration

Thanks Corey,

I am using BM but PTT don't seem to work and "wakeup" the TG's on BM. Also I appear to get TG's that should be on TS1 coming in on TS2.. I figured it was related to this,

DMRlink looks to the BM server as a "SmartPTT" connection. This is not like a Motorola, Hytera or even MMDVM. SmartPTT connections must be setup by a BM server administrator. The TS/TG mapping is not available to the repeater sysop. The TS/TG mapping is ALWAYS static, it can not be User Activated (PTT). SmartPTT connections will not dynamically create a TS/TG map.

BM will send data to SmartPTT on a TS in a "first come first serve" basis. Example: You have 2 static TGs on TS1 mapped from BM to SmartPTT. TG1 and TG2. If the TS is quiet, traffic on TS1/TG1 will be sent to SmartPTT. Now while the TS1/TG1 traffic is "flowing" Traffic appears on TS1/TG2, The TS1/TG1 traffic will not be interrupted. Once the traffic on TS1/TG1 drops, BM will IMMEDIATELY send the TS1/TG2 traffic to SmartPTT. Thus "stealing" the TS. The user on TS1/TG1 will not hear traffic on TS1/TG1 until the traffic on TS1/TG2 stops.

Based on the information above, choose the TS/TG you request from any single BM server with care. DMRlink does have rules to control routing TS/TG from BM to DMRlink. If you have to have more then 1 TG on a given TS from BM, You should consider breaking up your requests to multiple BM servers.

If you are using BM as your gateway it is already following the BM defaults.  IF you want to do something more then you need to use a conference bridge to accomplish what you want.

Hello All,

I am running dmrlink as follows,
BM <---> HB_Bridge <---> IPSC_Bridge <---> Motorola Repeater.

I have my talk groups statically trunked in and would like to setup a PTT method like on BM within this system. Is that possible? For example someone on my repeater keys up TG310 and it stays active for 5 minutes or whatever then closes again etc...

Ive looked through the wiki but it seems kinda slim ;)
