Thanks Steve, here it is:
; 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.
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)
address = 127.0.0.1 ; IP address of xx_Bridge
txPort = 31003 ; Transmit TLV frames to partner on this port
rxPort = 31000 ; Listen for TLV frames from partner on this port
ambeMode = P25 ; 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 = 1234567 ; ID to use when transmitting from Analog_Bridge
repeaterID = 123456789 ; ID of source repeater
txTg = 9 ; 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
; 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.
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?
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
