Thanks Steve, I thought I'd give it a try, more for the exercise - now I
need a P25 radio! :D  Results:

ASL - Analog_Bridge working.
Analog_Bridge - MMDVM_Bridge - Also working, I am seeing transmissions
from ASL appearing in the log as P25 being sent to P25Gateway.

But when I examine the P25Gateway logs, there is no activity, other than
the hourly updating of the hosts files.

Should I see anything in the P25Gateway log when traffic passes through?

I've used the same ports as in the documentation for everything except
between ASL and Analog_Bridge.  These were changed, because I have
multiple USRP interfaces running.

And another question.  How does one find out what P25 talkgroups are out
there?  The P25Hosts file is dated 2018 (is there a way to update this
from somewhere?), and P-Star seems to have a newer one.  And how do I
get a talkgroup listed, so other P25 gateways can find it?  Google was
quite unhelpful here. :(

Re: Audio stream of DMR talkgroup.

AB log path is set in the environment. Normally set by the systemd unit file. You can do that by:
AnalogBridgeLogDir=/var/log/dvswitch ; Analog_Bridge Analog_bridge.ini

I could not find a filepath= in Analog_Bridge to set a separate and different path for the second instance of Analog Bridge. Is there a way to send the log to a different location?

Steve,
You can't (don't need to) use apt-get.
You just need to copy the file/directory.
For example to copy the whole Analog_Bridge directory:
cd /opt
cp -rf Analog_Bridge Analog_Bridge2
Do the same for MMDVM_Bridge and md380-emu.
As JJ said, you are going to need to use different ports.

Re: Audio stream of DMR talkgroup.

Yes you can do that, the ports just have to be unique for the audio channels.

All,

I currently run ASL<>DMR in a Raspberry Pi that Includes ASL <>Analog Bridge<> MMDVM Bridge. Can I add another Private node in my existing ASL (Maybe 1998), and then add a second instance of Analog Bridge and MMDVM Bridge then install Lame and ezstream to send a DMR talk group to Broadcastify?  Does that sound like the best way?

Stephen, you are correct. I was a little too fast cutting and pasting text and swapped the order. I have sent the updated pdf to Steve for posting. ‘Hope it helps others.

Looks great! Thanks Tom! 

One correction I think needs to be added however (unless I've missed it myself), this should be added on page 11 after the "cd /tmp" step:

The document will help you build an ASL <-> P25 Bridge (includes a P25 Reflector) This is a no frills document. Tom shows you what files to edit and what fields to change. Includes some basic troubleshooting tips.

I like the simplicity of this. One of my favorite parts is that Tom ONLY changes the fields that need to change. Nothing more. Since the covers Analog_Bridge, MMDVM_Bridge and P25Gateway this is a good document for anyone bridging to P25 or connecting a Quantar to the P25 MMDVM Network for that matter. The document highlights one of the most basic principles of DVSwitch. That is the fact that most of the default settings just work. You don't have to edit every field in every file. If you understand the basic concept of DVSwitch you can get up and running pretty quickly. I'll leave it at this since it tells most everything you need to know:

 

A very large thank you to Tom for taking the time to create the document.

If you are trying to troubleshoot, check Analog_Bridge.log when you issue the command.

Yes you need cmd (copy and paste error)
It's in the same place as your 997 [functions] off the top of my head.

I typically call shell scripts with a function in the following way:

1)  Are you saying that I don't need       cmd,   preceeding the path/file ?

Re: asl.macro documentation / examples #analog_bridge

For what you are doing, you will use the macro functions to run a external program. That program is dvswitch.sh If you run dvswitch.sh without any parameters:

root@dvswitch:/var/www/html# /opt/Analog_Bridge/dvswitch.sh
Usage:
/opt/Analog_Bridge/dvswitch.sh
         { version | mode | tune | ambesize | ambemode | slot | update | tlvAudio | usrpAudio | usrpCodec | tlvPorts |
           info | show | lookup | mute | message | macro |
           pushfile | collectProcessDataFiles | collectProcessPushDataFiles | pushurl | collectProcessPushDataFilesHTTP }
         version {AB|MB|ALL}                             Show version of dvswitch.sh, Analog_Bridge or MMDVM_Bridge
         mode {DMR|NXDN|P25|YSF|DSTAR}                   Set Analog_Bridge digital mode
         tune tg                                         Tune to specific TG/Reflector
         ambesize {72|88|49}                             Set number of bits for ambe data
         ambemode {DMR|NXDN|P25|YSFN|YSFW|DSTAR}         Set AMBE mode
         slot {1|2}                                      Set DMR slot to transmit on
         update                                          Update callsign and host databases
         tlvAudio mode gain                              Set AMBE audio mode and gain
         usrpAudio mode gain                             Set PCM audio mode and gain
         usrpAgc threshold slope decay                   Set PCM audio agc threshold slope and decay
         usrpCodec {SLIN|ULAW|ADPCM}                     Set AB -> DVSM/UC audio codec
         tlvPorts rxport txport                          Set Analog_Bridge receive and transmit ports
         info                                            Update ABInfo and send to DVSM/UC
         show                                            Pretty print the ABInfo json file
         lookup                                          Lookup a DMR ID/call in the local database
         mute {OFF|USRP|TLV|BOTH}                        Cause Aanlog_Bridge to mute a stream
         message msg                                     Send a text message to DVSM/UC
         macro {file|text}                               Send a macro collection to DVSM
         pushfile file                                   Push file to DVSM
         pushurl url                                     Push URL to DVSM
         collectProcessDataFiles                         Collect and prepare DVSM data files
         collectProcessPushDataFiles                     Collect, prepare and upload DVSM data files
         collectProcessPushDataFilesHTTP                 Collect, prepare and upload DVSM data files over http
         reloadDatabase                                  Tell AB to reload database files into memory
         getEnabledModes                                 Return the list of enabled modes in MB.ini

for example you would create a macro to run a external program in rpt.conf
73 = /opt/MMDVM_Bridge/dvswitch.sh tune 10200

dvswitch.sh would tell AB and MB to change TG to 10200

dvswitch.sh update
dvswitch.sh would download all the host files and databases needed to /var/lib/dvswitch and /var/lib/mmdvm
