Tips on setting up your config files in /opt/Analog_bridge and MMDVM_Bridge

 

Items highlighted in green are what I changed from the defaults (Coming Soon)

 

My Ananlog_Bridge.ini file

 

; Analog_Bridge configuration file.

;   This file should be placed in either /etc or it can be

;   supplied as a path on the Analog_Bridge command line.

 

; The best way to think of this file is that there are two main sections, the USRP (analog audio) and

; AMBE_AUDIO (compressed audio).  Analog_Bridge will take everything sent to the USRP port and

; encode it for transmission on the AMBE_AUDIO port.  The encoder will use the format defined in ambeMode.

; As you might expect, the reverse direction is defined too.

 

 

; 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

subscriberFile = ./subscriber_ids.csv   ; DMR ID to callsign lookup data

exportMetadata = true                   ; Export metadata to USRP partner (transcode setups require this)

 

; 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

 

; 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 = 2500                      ; 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 = 3136728                        ; ID to use when transmitting from Analog_Bridge

repeaterID = 313672804                          ; ID of source repeater

txTg = 3136728                      ; TG to use for all frames sent from Analog_Bridge -> xx_Bridge Use your 7 digit DMR ID as the Talkgroup

txTs = 2                                ; Slot to use for frames sent from Analog_Bridge -> xx_Bridge

colorCode = 1                           ; Color Code to assign DMR frames

 

; Information for USRP channel driver.  This interface uses PCM to transfer audio information

; There are two typical configurations, ASL and Transcode.  ASL (AllstarLink) is for analog clients connected

; to a digital network.  Transcode is when Analog_Bridge actually points its PCM interfaces back at itself,

; causing a TLV <– (pcm <–> pcm) –> TLV type of architecture.

;   When using ASL, this matches the rpt.conf ASL file with a setting like:

;   rxchannel = usrp/127.0.0.1:34001:32001

;   When Transcoding, make two ini files and set txPort equal to the other instance rxPort (crossover).  Launch

;   each instance with its own ini file.

[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)

 

; Information for DV3000 hardware decoder

;   There are two configuration modes: IP (AMBEServer) and serial (direct connect hardware)

;   Use top server and port if using AMBEServer

;   Use bottom server/port and serial = true if using the DV3000u (thumbdv)

;   Did you run AMBETest4.py before using this?

[DV3000]

address = 127.0.0.1                     ; IP address of AMBEServer

rxPort = 2460                           ; Port of AMBEServer

; address = /dev/ttyUSB0                ; Device of DV3000U on this machine

; baud = 460800                         ; Baud rate of the dongle (230400 or 460800)

; serial = true                         ; Use serial=true for direct connect or serial=false for AMBEServer

Edits to the Allstar configuration

Add a private node to your rpt.conf file

 

/etc/asterisk/rpt.conf

 

[1999]

rxchannel = USRP/127.0.0.1:34001:32001 ; Use the USRP channel driver. Must be enabled in modules.conf

                        ; 127.0.0.1 = IP of the target application

                        ; 34001 = UDP port the target application is listening on

                        ; 32001 = UDP port ASL is listening on

duplex = 0                     ; 0 = Half duplex with no telemetry tones or hang time. Ah, but Allison STILL talks!

hangtime = 0                     ; squelch tail hang time 0

althangtime = 0                 ; longer squelch tail hang time 0

holdofftelem = 1                 ; Hold off all telemetry when signal is present on receiver or from connected nodes

                        ; except when an ID needs to be done and there is a signal coming from a connected node.

telemdefault = 0                 ; 0 = telemetry output off. Don’t send Allison to DMR !!!!!!!!!!!!!!!!! Trust me.

telemdynamic = 0                 ; 0 = disallow users to change the local telemetry setting with a COP command,

linktolink = no                 ; disables forcing physical half-duplex operation of main repeater while

                        ; still keeping half-duplex semantics (optional)

nounkeyct = 1                 ; Set to a 1 to eliminate courtesy tones and associated delays.

totime = 180000                 ; transmit time-out time (in ms) (optional, default 3 minutes 180000 ms)

idrecording = |ie                 ; id recording or morse string see http://ohnosec.org/drupal/node/87

idtalkover = |ie                 ; Talkover ID (optional) default is none see http://ohnosec.org/drupal/node/129

 

 

 

Further down in your Node Stanza setup a startup macro

startup_macro = *31999

 

And in the Nodes Stanza add your private node

[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.

 

48418 = radio@127.0.0.1:4563/48418,NONE    ; This must be changed to your node number

                                                                    ; and iax port number if not the default

1999 = radio@127.0.0.1:4563/1999,NONE
