Re: Help linking P25 to DMR

mike@...
 

Thank you Steve - it's working now! The last sticky bit is that the MMDVM_bridge connection to the BM master times out repeatedly, about every 2 minutes. This happens on BM master 3103 and 3102. Any thoughts on this one? Thanks again! 

Mike

You have 2 instances of Analog_Bridge. One is configured for DMR (that is connected to the MMDVM_Bridge connecting to BM) and one is configured for P25 (That is connected to MMDVM_Bridge configured for P24)
Is this correct?

Re: Help linking P25 to DMR

Steve N4IRS
 

Mike is correct. Analog_Bridge_DMR communicates with DVSwitch.ini DMR Stanza
Analog_Bridge_P25 communicates with DVSwitch.ini P25 Stanza
You can not use the same ports.
I suggest you use the default values in DVswitch.ini and match the instance of Analog_Bridge to match it.

Also,
In Analog_Bridge_DMR.ini you can not leave the gatewaydmrid and repeaterID to 0. Set them to real values.

You have 2 instances of Analog_Bridge. One is configured for DMR (that is connected to the MMDVM_Bridge connecting to BM) and one is configured for P25 (That is connected to MMDVM_Bridge configured for P24)
Is this correct?

The 2 MMDVM_Bridges can be done as one instance.

As a point of reference I am currently transcoding the following things over to ASL on a single RPi3B+

NXDN -> md380emu -> Analog_Bridge -> ASL
C4FM -> md380emu -> Analog_Bridge -> ASL
DMRLink -> IPSC_Bridge -> HB_Bridge -> hblink3 -> DV3000 -> Analog_Bridge -> ASL

Note that each "ASL" above is a separate "node" within the same ASL instance on the RPi and that the system load is minimal (all three are active at the same time when a transmission is made).

DMR to the Bridge Echolink conference server

The bridge is an iLink/EchoLink compatible conference bridge and we have been using it to host our Echolink conference server. I was wondering if anyone tried using DVSwitch to link DMR and TBD ?
And if not, what would you recommend for linking DMR and Echolink only ( non allstar node )
Re: OpenBridge issue both bm&ipsc2

Cort N0MJS <n0mjs@...>
 

Yep, that’s expected and known. IPSC2 servers send one additional packet at the end of a data stream that is outside of the protocol spec defined by DMR+ and Brandmeister. It does not affect usability. To date I have had no luck finding out what it is, though Artem at Brandmeister was going to try and look into it. BM has made the protocol open to all, DMR+ considers it their IP and is not interested in publication.

+1 Brandmeister
-1 DMR+

You can ignore it. It is not causing problems.

Which brings up something in general for everyone – just because something might look “bad” to you in a log doesn’t mean something is failing. I log a LOT OF STUFF. Please assume that, unless something in practice is failing, many log messages that look ominous are not.

Re: Is this even possible?

I've been sick the last 6 weeks or so, but I'm finally getting back on my feet.

During my convalescence, I didn't have much energy to work on this project.  But now, I'm ready to get back to it, and make this all work.

Corey, for setting up an openbridge feed from BM, should I coordinate directly with you, or should I contact the dmr-admins (at) repeater.net address?  Do I need to pre-choose the talkgroups I want fed to me via the openbridge, or is it more like the self-serve features of the normal BM console?

I already have a working feed of 8802 from K4USD that I'm happy with.  It has been rock solid, and I'd like to just keep using that feed since it's already functional.

Thank you again for all the assistance,
Jim

Now that openbridge is released I may be able to help out some here.  I have about 15-20 talkgroups from bm 3102 feeding hblink using openbridge.  I then have a link into my cbridge carrying Delmarva 8802, then I also have a backup system of hblink with all of those coming across it.  My home brew repeaters connect directly to hblink and the 8300 repeaters use IPSec bridge / hb bridge to connect to hblink.  I have been running it this way for a few months with no trouble at all!

If I need another talkgroup from the cbridge or bm it is very easy to add.  On openbridge all I need to know is the talkgroup I’d, enter it in and you have it right away.  Think of it as a cbridge cclink with out the need for a lid.

Jim, you can do what you want to do now with the use of HBLink, DMRLink, HB_Bridge and IPSC_Bridge as follows:

hb_confbridge <-> Brandmeister (for BM TGs)
hb_confbridge <-> hb_bridge <-> ipsc_bridge <-> confbridge (for CBridge interfacing and interfacing to motorola repeaters)

hb_confbridge is a single instance of hb_confbridge.py from HBLink
confbridge is a single instance of confbridge.py from DMRLink
ipsc_bridge and hb_bridge are the respective single instances of the .py files from IPSC_Bridge and HB_Bridge.

All that you have to do is configure the respective _rules.py files to determine what TGs are allowed to go to what system, simply excluding TG8802 from your Brandmeister stanza in said file will do it.

A lot has happened in the last few weeks.  Most critically, the OpenBridge branch merged back into the master branch, bringing with it new goodies to play with, namely ACLs!

Additionally, I've stopped trying to conflate my needs with the needs of the other repeater operator, instead treating each as a unique problem to be solved.  Since his is closer to being on the air, I'm focusing on that.  I'm hoping for OpenBridge to be the answer to my own setup in the near future.

Basic premise: new (used) repeater, VHF, XPR8400, 147.210 +, CC1,  antenna at 300' on a county tower, owner: N4TIK (Ken), trustee: W0ADD (Al).

Ken and Al would prefer their repeater have the sysop level of control provided by Brandmeister rather than being on a cBridge and having to pester the bridge operator for changes.  However, they also want to carry the DelMarVa (8802) talkgroup, primarily for coordination across the region during EmComm scenarios, which is only carried on cBridges currently.

For policy reasons, 8802 will not be carried by BM.

The repeater is operational, barring some issues with the duplexer.  It's connected to BM currently, and operating as the owner and trustee wish it to, although lacking the 8802 talkgroup.

Existing configuration:

I think that with the advent of ACLs, I can insert a DVSwitch suite in between the XPR8400 and the BM3102 server.  I can use the ACLs to deny 8802 from going to BM3102, and also to permit only 8802 on TS1 going to/from K4USD.

Proposed configuration:


In this proposal, the IPSC_Bridge <-> BM3102 link would be using the N4TIK DMR ID # 310328, so would look the same as the existing repeater.

Does anyone see anything wrong with this approach?

Yes, I know BM supports HB directly, but I don't know what's involved with changing from the current IPSC connection to an HB connection, ie will BM even care? Is it a different port?  For that matter, I don't *know* that the IPSC_Bridge <->BM3102 link will function correctly.   Any advice on this point is very welcome.

Thanks in advance,
Jim

PS, hooray for ACLs!

I've reached the point where I need someone with experience with these tools to point me in the right direction.  I think I am getting overwhelmed with too much "there's more than one way to do it" combined with not knowing the limitations of the various branches of dmrlink and hblink (IPSC_Bridge and HB_Bridge specifically).

I have the need to connect 2 repeaters up to 2 different networks simultaneously.  One repeater is Mototrbo/IPSC and the other is MMDVM/Pi-Star.  One of the networks is a cBridge, and the other is Brandmeister.

On the IPSC repeater, the requirement is to have TS1 TG8802 and TS2 TG3151 by default, with TG8802 sourced from the cBridge, and TG3151 sourced from either the cBridge or Brandmeister.  I can get it from either source, but TG8802 is only from the cBridge due to policy.  The part that makes it difficult for me to know how to implement it is that the repeater owner wants TS1 to share with "any possible" BM TG, with a PTT setup with 15 minute timeout to revert to TG8802.

On the MMDVM repeater, the requirement is to have TS1 TG8802 and TS2 TG3151 by default.  Again, TG8802 sourced from the cBridge, and TG3151 from either.  The repeater owner on this one is me, and I'd rather have my PTT groups on TS2, and I don't necessarily care if it is "any possible" BM TG or simply a predefined subset.

Eventually, we might add additional DMR repeaters into the mix, and have different requirements for them.

I've started with a pristine install of Ubuntu 18.04 LTS, updated it, added Steve's DVSwitch-System-Builder script, and followed its directions.

Any suggestions for the best way to implement the system as described, or as closely as possible?

Thanks in advance,

In case anybody else encounters that "D-Star lost audio" error :
According to Murphy's Law, the cause was completely external to Analog_Bridge / MMDVM_Bridge setup :

xlx ambed daemon had a malfunction. Errors were present in XLX log. Strangely, it scrambled all XLX traffic, including traffic that did not require XLX transcoding. This also affected Analog_bridge traffic.

Restarting ambed solved that problem.

Hi,

My setup is probably not what you want.  The ASL link is to a DMR talk group:

Asterisk <-> chan_USRP <-> Analog_Bridge <-> MMDVM_Bridge <-> DMR TG


Thank you for your answer. Here, the XLX is the central part of the system. It has internal transcoding, and all other stuff (including Asterisk hub) will connect to it. What I'm trying to do is :
Asterisk Hub <-> chan_USRP <-> Analog_Bridge <-> MMDVM_Bridge <-> ircddbgatewayd <-> XLX
Here's the current status :
- From XLX to Asterisk : it works perfectly
- From Asterisk to XLX : <nothing>

On the XLX log, I can see packets arriving from my Asterisk node, but it's as if they are not interpreted as a connection request by XLX :
Jan 14 22:51:01 xlx xlxd: DCS packet (100) from 10.44.0.3
Looking at MMDVM_Bridge, I can see D-Star outgoing packets :
M: 2019-01-15 09:38:53.337 D-Star link status set to "Connected to DCS755 K "
M: 2019-01-15 09:39:41.514 D-Star, TX state = ON
I: 2019-01-15 09:39:41.514 D-Star, Begin TX: src=6693310 rpt=2080199 dst=6 slot=2 cc=1 metadata=208019902

Something seems to be wrong here :
- TK5KP is the callsign of my gateway
- 2080199 is the DMR-ID of TK5KP. This field is the source caller ID. I would expect it to contain a D-Star callsign, not a CCS7 ID.

Problem :
It seems MMDVM_Bridge is sending a D-Star connection frame with a DMR-ID instead of a D-Star callsign, which makes XLX ignore it.

Additional question :
Can I use the same callsign (TK5KP) for ircddb gateway callsign, MMDVM_bridge "repeater" callsign, and source callsign (which will appear on D-Star network for data originating from Asterisk) ?

Thank you in advance for your help.
