ALLSTARLINK ECHOLINK BrandMeister DMR
ALLSTARLINK ECHOLINK BrandMeister DMR
In continuation to the previous post regarding Allstarlink on raspberry pi, the following is with reference to allstarlink with echolink and DMR all in one package. I have been testing out ASL versions and chose allstarlink.org distribution. Am sure it shall also work with the HamVoip version.
This post doesnot cover the ASL install and its features and assumes the reader is proficient with the ASL infrastructure. some of the main resources and extracts that were used are at the end
ASL to DMR Bridge how
We are going to take you through installing
one of the most requested DVSwitch bridge types, an Analog to DMR bridge.
Throughout this document, we will use real node numbers, real DMR IDs and real
TG numbers. Where possible those values will be green. Please substitute your numbers. We will start with a already running ASL node
and add the required parts to bridge it to BrandMeister DMR.
Throughout this document we will be testing
along the way. If you do not get the expected results as shown, stop, check
your work and if it all looks right, ask for help. It is a LOT easier to
troubleshoot at the points along the way rather than at the end.
Step 1:
Go
to https://radioid.net/register#! and register for your DMR ID. You
shall recieve an email from radioid.net after they verify the provided
HAM license.
Step 2:
Go
to https://brandmeister.network/ and register your account, they shall
send you an email confirming your account and dashboard is activated.
Step 3:
Everything we will do from this point on needs
root privileges, so once logged in as user repeater:
Gain root privileges
|
sudo -s
|
Change to the asterisk configuration file
directory:
At the # prompt:
|
cd /etc/asterisk
|
Check if asterisk is running:
|
systemctl status asterisk
|
|
root@repeater:/etc/asterisk#
systemctl status asterisk
● asterisk.service - Asterisk PBX and telephony daemon Loaded: loaded (/lib/systemd/system/asterisk.service; enabled; vendor preset: enabled) Active: active (running) since Mon 2018-06-04 08:55:52 EDT; 21s ago Docs: man:asterisk(8) Process: 601 ExecStop=/usr/sbin/asterisk -rx stop now (code=exited, status=0/SUCCESS) Main PID: 698 (asterisk) Tasks: 21 (limit: 4915) CGroup: /system.slice/asterisk.service └─698 /usr/sbin/asterisk -g -f -C /etc/asterisk/asterisk.conf Jun 04 08:55:52 repeater systemd[1]: Started Asterisk PBX and telephony daemon. |
It is much easier to make your changes and
then run the program in the foreground to troubleshoot before continuing.
Stop asterisk and get its status:
|
systemctl stop asterisk
systemctl status asterisk
|
|

ASL will support multiple nodes on one server.
For the bridge, this allows us to easily connect and disconnect ASL from DMR.
Not all nodes on ASL need be in the public node list. These type of nodes are
called private nodes. We are going to add a private node to ASL. This minimizes
the changes required to ASL. The settings for node 1999 are selected to keep
unwanted sounds from being sent to DMR from ASL.
Edit /etc/asterisk/rpt.conf
Copy the [1999] stanza from
https://dvswitch.groups.io/g/allstarlink/wiki/home
Paste the stanza for the private node at the
top of rpt.conf file.

;
34001 = UDP port the target application is listening on

idtalkover
= |ie ; Talkover

|
|
|
Next we need to add the configuration for node
1999
In the [nodes] stanza:
Add:
1999 =
radio@127.0.0.1:4569/1999,NONE
The [nodes] stanza should look like this:
|
[nodes]
; Note, if you are using automatic
update for allstar link nodes,
; no allstar link nodes should be
defined here. Only place a definition
; for your local nodes, and
private (off of allstar link) nodes here.
2100 =
radio@127.0.0.1:4569/2100,NONE ; This
must be changed to your node number
1999 =
radio@127.0.0.1:4569/1999,NONE
|
We are finished editing rpt.conf.
Next we must enable the USRP channel driver.
Edit /etc/asterisk/modules.conf
In the [modules] stanza
Change:
noload => chan_usrp.so
To:
load => chan_usrp.so
The line should look like this:
|
load =>
chan_usrp.so ;
GNU Radio interface USRP Channel Driver

Now let’s check our work. Run asterisk in the
foreground

Press Control-C to exit asterisk
It is
best practice to build from the outside in. From shore to shore, so to speak.
We can now move on to connecting to BrandMeister.
Let’s install the DVSwitch programs needed to
connect ASL to BrandMeister:
Make sure your repository list is up to date
before trying to install more programs.
Run:
|
apt-get update
|
If you see no errors let’s add the DVSwitch
programs:
The ASL and DVSwitch Repository are both
hosted on dvswitch.org so the DVSwitch programs are available.
Run:
|
apt-get install dvswitch -y

This
installs Analog_Bridge, MMDVM_Bridge, and md380-emu. The scripts and datafiles
needed to support these programs are also installed. Each of the programs is
set to start at boot. You don’t have to do anything.
Before we start, Let’s take a look at how this
all goes together. Usually in the message board you will see a simple ASCII
diagram like this:
ASL <-> Analog_Bridge <->
MMDVM_Bridge <-> BrandMeister
The <-> denotes two way communications
between the programs. This is done via UDP ports. Since the DVSwitch programs
can be configured to build a large number of different bridges, the number of
options can be staggering to a first time user. Focus on the project at hand.
In reality there are not too many changes that need to be made. We have tried
to be consistent in the naming between programs and to set the default value as
someone would use in a simple bridge. Here is a port diagram of what you will
be building:
From left to right, we start with The [1999]
node stanza. Each node has a rxchannel. This defines how the node communicates.
In this case, we will use USRP to communicate with Analog_Bridge. 127.0.0.1 is
the address that ASL will send data to Analog_Bridge. 34001 is the UDP port
that ASL will send data on. 32001 is the port that ASL will listen for data on.
In Analog_Bridge.ini the [USRP] stanza defines
how Analog_Bridge will communicate with another USRP Partner. In this case ASL.
127.0.0.1 is the address that Analog_Bridge will send data to. Port 32001 is
the port that Analog_Bridge will send data to ASL on. Port 34001 is the port
that Analog_Bridge will listen for data from ASL on.
In Analog_Bridge.ini the [AMBE_AUDIO] stanza
defines how Analog_Bridge will communicate with a digital Partner. In this case
MMDVM_Bridge. 127.0.0.1 is the address that Analog_Bridge will send data to.
Port 31103 is the port that Analog_Bridge will send data to MMDVM_Bridge on.
Port 31100 is the port that Analog_Bridge will listen for data from
MMDVM_Bridge on.
MMDVM_Bridge is the program that connects to
BrandMeister. Let’s check it’s status:
|
systemctl status
mmdvm_bridge
|
|
root@repeater:/etc/asterisk# systemctl status mmdvm_bridge
● mmdvm_bridge.service -
MMDVM_Bridge Service
Loaded: loaded (/lib/systemd/system/mmdvm_bridge.service; enabled;
vendor preset: enabled)
Active: inactive (dead)
|
You will see the status of the mmdvm_bridge
service
Good, MMDVM_Bridge is not running though it is
enabled, meaning it will start at boot.
Change directory to /opt/MMDVM_Bridge
|
cd /opt/MMDVM_Bridge
|
Let’s see what files are in the directory
/opt/MMDVM_Bridge
|
ls
|
|
root@repeater:/etc/asterisk# cd /opt/MMDVM_Bridge/
root@repeater:/opt/MMDVM_Bridge# ls
DVSwitch.ini MMDVM_Bridge MMDVM_Bridge.ini
root@repeater:/opt/MMDVM_Bridge#
|
You will see the program and it’s two
configuration files.
We will now edit the callsign and Id
Edit /opt/MMDVM_Bridge/MMDVM_Bridge.ini
In the [General] stanza
Change:
Callsign=W1AW
To your callsign:
Callsign=AP2CJ
Change:
Id=1234567
To your DMRID + 2 digit SSID
Id=311213805
The [General] stanza will look like this:
|
[General]
Callsign=AP2CJ
Id=311213805
Timeout=180
Duplex=0
|
In the [General] stanza, the callsign is your
callsign. For the Id, It is STRONGLY recommended to user your DMRID and append
a 2 digit number between 01 and 99. These 2 digits are referred to as SSID For
this example that’s 3112138
plus 05. So the Id in
the [General] stanza is 311213805.
This is how MMDVM_Bridge logs into a BrandMeister Master. This will make it
MUCH easier for you to control any static Talk Groups you want for your bridge.
We will now enables the DMR mode in MMDVM_Bridge.
In the [DMR] stanza
Change
Enable=0
To:
Enable=1
The [DMR] stanza will look like this:
|
[DMR]
Enable=1
ColorCode=1
EmbeddedLCOnly=1
DumpTAData=0
|
In this example, we will connect to the
BrandMeister Master at 3108.repeater.net
You should use YOUR regional Master here.
In the [DMR_Network] stanza
Change:
Address=dvswitch.org
To:
Address=3108.repeater.net
The [DMR Network] stanza will look like this:
|
[DMR Network]
Enable=1
Address=3108.repeater.net
Port=62031
Jitter=360
Local=62032
Password=passw0rd
Slot1=0
Slot2=1

This verifies the Callsign and the Id used to
login to BrandMeister. The BrandMeister Master Address and Port you are
connected to and that you have successfully logged in to the Master.
Let’s take a look at BM. Login to your
selfcare page at brandmeister.network.
On the left hand side you should see “My
hotspots”
Notice that 311213805 is showing the green “plug” icon. That
means 311213805 it is
connected to BrandMeister. Next let’s take a quick look at it’s edit page.
Click on your hotspot number. For the example, that’s 311213805 This will take you to the edit page.
In the center of the page you should see Sysops. You should be the only sysop
for now. If you got this far you are most of the way there.
While we are here, we can setup a Static Talk
Group to pass through the bridge. We will add the Talk Group number here:
Enter your Talk Group number in the box on the
left and click on the right arrow. It will look like this, for the example I
used Talkgroup 311222:
At this point, you have both sides of bridge
installed and working. Now it is time to connect them together. Since one
network is analog and the other network is digital we need to convert the audio
between the modes. That is the job of Analog_Bridge.
Press Control-C to stop MMDVM_Bridge.

Edit /opt/Analog_Bridge/Analog_Bridge.ini
in the [GENERAL] stanza
change:
decoderFallBack = true
The [GENERAL] stanza will look like this:
|
; General Section describes
settings for Analog_Bridge itself.
[GENERAL] logLevel = 2 ; Show messages and above 0=No logging, 1=Debug, 2=Message, 3=Info, 4=Warning, 5=Error, 6=Fatal ; Metadata management exportMetadata = true ; Export metadata to USRP partner (transcode setups require this) subscriberFile = /var/lib/dvswitch/subscriber_ids.csv ; DMR ID to callsign lookup data ; General vocoder setup information decoderFallBack = true ; Allow software AMBE decoding if a hardware decoder is not found useEmulator = false ; Use the MD380 AMBE emulator for AMBE72 (DMR/YSFN/NXDN) emulatorAddress = 127.0.0.1:2470 ; IP address and port of the md380 server;s |
The [AMBE_AUDIO] stanza sets up the connection
to the Partner program.
In this example, MMDVM_Bridge.
RXPort is the UDP port that Analog_Bridge will
listen to for data from MMDVM_Bridge.
Address and TXPort are where Analog_Bridge
will send data to MMDVM_Bridge.
The default values for Address, RXPort and TXPort
are correct for connecting to the [DMR] stanza in MMDVM_Bridge.ini
gatewayDmrId is the DMRID that all analog
traffic from ASL will appear to come from when someone is listening on DMR.
repeaterID should match the ID you used to log
into BM.
txTg is the Talk Group that traffic from ASL
will be sent to BrandMeister.
txTs is the Time Slot the traffic from ASL
will be on.
In the [AMBE_AUDIO] stanza
Change:
gatewayDmrId = 3112138
repeaterID = 311213805
txTg = 311222
repeaterID = 311213805
txTg = 311222
txPort = 31103
rxPort = 31100
rxPort = 31100
Remember the values in green are for the example. You should use your
values here.
CHANGE
THE Analog INI
DVSwitch.ini | Analog_bridge.ini
[DMR] | [AMBE_AUDIO]
Address = 127.0.0.1 |
server = 127.0.0.1
TXPort = 31100 | fromDMRPort = 31100
RXPort = 31103 | toDMRPort = 31103
The [AMBE_AUDIO] stanza will look like this:
|
; Information for xx_Bridge (Where
xx is MMDVM, Quantar, HB, IPSC)
[AMBE_AUDIO]
address = 127.0.0.1 ; IP address of
xx_Bridge
txPort = 31103
; Transmit TLV frames to partner on this port
rxPort = 31100
; Listen for TLV frames from partner on this port
ambeMode = DMR ; DMR, DMR_IPSC,
DSTAR, NXDN, P25, YSFN, YSFW (encode PCM to this format)
minTxTimeMS = 2000 ; Minimum time in MS
for hang delay (0-10000)
; The metadata below is used when
ASL is the source since it does not have any concept of digital modes
gatewayDmrId = 3112138 ; ID to use when
transmitting from Analog_Bridge
repeaterID = 311213805
; ID of source repeater
txTg = 311222 ; TG to use for
all frames sent from Analog_Bridge -> xx_Bridge
txTs = 2 ; Slot to use
for frames sent from Analog_Bridge -> xx_Bridge
colorCode = 1 ; Color Code to
assign DMR frames
|
Now we will look at the Analog side of the
connection:
The [USRP] stanza will look like this:
|
[USRP]
address = 127.0.0.1 ; IP address of USRP
partner (Allstar/Asterisk or another Analog_Bridge)
txPort = 32001
; Transmit USRP frames on this port
rxPort = 34001
; Listen for USRP frames on this port
aslAudio = AUDIO_UNITY ; Audio to ASL
(AUDIO_UNITY, AUDIO_USE_AGC, AUDIO_USE_GAIN)
agcGain = -20 ; Gain (in db) of
the AGC filter
dmrAudio = AUDIO_UNITY ; Audio from ASL
(AUDIO_UNITY, AUDIO_USE_GAIN, AUDIO_BPF)
dmrGain = 0.35 ; Gain factor of
audio from ASL (0.0-1.0)
|
The [USRP] stanza is what is used to connect
to ASL. This is also where you can tailor the audio in and out of ASL to DMR.
For now the defaults will work as is. We are done editing Analog_Bridge. Let’s
check our work.
Run Analog_Bridge in the foreground.

Analog_Bridge is sending data to MMDVM_Bridge
at Address 127.0.0.1 on port 31103 Aanlog_Bridge is listening for data from
MMDVM_Bridge on port 31100.
Analog_Bridge is sending analog audio to ASL
at Address 127.0.0.1 on port 32001 Analog_Bridge is listening for analog audio
from ASL on port 34001.
Audio levels to and from ASL are unity. (no
gain or reduction)
Insert
Vocoder discussion here:
Analog_Bridge is capable of using three
classes of vocoders
Hardware DV3000U,
PiDV, DVMega AMBE
Support
for DMR, YSFN, NXDN and D-Star
Direct
serial and IP (ambe server) modes are supported
Software
The
md380-emulator
Support
for DMR, YSFN, NXDN
The
OP25 vocoder
Support
for DMR, YSFN, NXDN, D-Star, P25 and YSFW
Quality vs cost
Will your CPU support all vocoders?
As described in other sections, we support
AMBE, IMBE and DSAMBE audio formats, but there are differing levels of support
and quality for these formats.
AMBE is supported in hardware (USB or
AMBEServer), md380-emulator on supported environments and OP25 vocoder for all
platforms. The md380-emulator is
available on x86 and ARM V7 (with div support) which includes the Raspberry Pi
2 and 3, Allwinner H3 and H5 processors.
IMBE is supported in software on all platforms
using the OP25 vocoders
DSAMBE (D-Star) is supported in hardware (USB
or AMBEServer) and (but you will not be happy) by using the OP25 vocoder.
If you got this far, you are doing well. It’s
now time to test everything and see if we missed anything. For this portion you
will run all of the bridge programs in the foreground. Each will be in a
separate window so you can watch in real time. Again we will work from the
outside in.
Let’s start asterisk. We will also tell
asterisk to use more verbose logging so that we can see the traffic coming from
Analog_Bridge.

Traffic is flowing from DMR to ASL! ! Did you get the above results? If you did
not, stop. Check your work before continuing. If you did, let’s test in the
other direction from ASL to DMR. You could use a radio on the ASL node for this
but there is a simply way for your first test to do this without an analog
radio.
While still logged in to asterisk at the
CLI> prompt
Tell asterisk to send a 1 KHz test tone.

If you still have your DMR radio and HotSpot
connected, you should hear the tone coming out of your radio. You do? We have
liftoff !
Let’s stop the annoying tone.
While still logged in to asterisk at the
CLI> prompt
Tell asterisk to STOP sending the 1 KHz test
tone.
|
*CLI> rpt cmd 1999 cop 4 1999
|
Yes, the cop 4 command is a toggle, once on
and once off. Please remember to turn it off.
Congratulations, You have built your very own
ASL <-> DMR bridge. We hope that was not too bad and you learned a few
things along the way. Just a few little cleanup tasks to do and you are ready
to run.
The debug level in asterisk will quickly fill
your log file with mostly unneeded information. Let’s set it back to a sane
value.
Make the asterisk messages less verbose
From the CLI> prompt
|
rpt debug level 0
|
You probably want your public node to connect
to the the DMR node when asterisk starts. We will use the startup macro in
rpt.conf to do this for you.
Change to the /etc/asterisk directory
|
cd /etc/asterisk
|
Edit rpt.conf
Set the startup macro to connect your public
node to your private node by setting
startup_macro = *31999 in the [2100]
node stanza.
Edit /etc/asterisk/rpt.conf
In the [2100] node stanza
Change:
startup_macro =
To:
startup_macro = *31999
The line should look like this:
|
startup_macro
= *31999
|
Now it’s time to make sure everything will
start at boot and do what you expect.
We will enable all the services we need just
in case.
At the # prompt:
|
systemctl enable asterisk
systemctl enable analog_bridge
systemctl enable md380-emu
systemctl enable mmdvm_bridge
|
If the system was silent, that means those
services were already enabled. No harm done.
OK, here we go:
At the # prompt:
|
reboot
|
Once the system is up:
Open a window on the bridge
Gain root privileges
|
sudo -s

OK, you have been a very diligent person, time
for a little fun
Connect to the running instance of asterisk
|
Asterisk -r
|
At the CLI> prompt
|
rpt
cmd 1999 cop 21 1999
|
Hmmm, nothing happened? You expected
fireworks?
Key your DMR radio and identify.
Did you hear yourself (parrot)? That’s right,
ASL has a parrot function and it just proved your bridge is working in both
directions. Your DMR audio was actually parroted by ASL. A full round trip. A
pretty quick and easy way to verify everything is working as expected.
Before you start getting strange phone calls,
we better turn off the parrot.
At the CLI> prompt
|
rpt
cmd 1999 cop 22 1999
|
Get up, walk around, pat yourself on the back.
It works! We will cover some basic info and then you can go play. School is not
quite out yet.
Below is some basic information you will need
to maintain your bridge:
File locations
Programs
In /opt/program_name
/opt/MMDVM_Bridge/MMDVM_Bridge
Configuration files
With the program
/opt/MMDVM_Bridge/MMDVM_Bridge.ini
Datafiles
In /var/lib/mmdvm or
/var/lib/dvswitch
/var/lib/mmdvm/DMRIds.dat
Logs
In /var/log/mmdvm,
/var/log/dvswitch, /var/log/asterisk
/var/log/mmdvm/MMDVM_Bridge-2018-05-22.log
For the log files
you can watch what one of the programs in real time by “tailing” the log files.
For example:
tail -f
/var/log/dvswitch/Analog_Bridge.log will show you what is going on with
Analog_Bridge. Key your DMR radio and ID. See the traffic?
Scripts
In /usr/local/sbin
/usr/local/sbin/DMRIDUpdate.sh
Daily cron tasks to
update data files
/etc/cron.daily/DMRIDUpdate (this is
a symbolic link to the script
In /usr/local/sbin
Note: If you want to add a link, the link name should not have a extension
(.sh)
Status,

systemctl

systemctl

There are some final adjustments you will
probably want to make to your bridge. You can control the audio level from ASL
to DMR. You can also control the audio level from DMR to ASL. Both these values
are in Analog_Bridge.ini. Let’s take a look.
[USRP]
address = 127.0.0.1
txPort = 32001
rxPort = 34001
aslAudio = AUDIO_UNITY
agcGain = -20 ; Gain (in db) of the AGC
filter
dmrAudio = AUDIO_UNITY
dmrGain = 0.35 ; Gain factor of
audio from ASL (0.0-1.0)
AUDIO_UNITY Means pass the audio as is. No
gain or reduction.
AUDIO_USE_AGC Normally not used.
AUDIO_USE_GAIN The Gain value can be from 0.0
to 10.0 or anything in between. A value less then 1.0 reduces the audio level
to a percentage. Example: .75 is 75 percent of full volume or unity. A value of
1.0 to 10.0 increases the by a power of the number. Example: 3.0 is three time
the level.
These values a labels will be changing to
something more specific to the usage. ( Due to me trying to document usage )
Grin Funny how you find things this way.
