I’ve setup several of these ASL<->DMR bridges now. Personally, I try to keep the “bridges” setup on “Private” nodes & then have them auto connect to your public node on startup once you have everything working properly. The startup macro works great for this. I do this so just in case a problem arises, you can always disconnect the “Private Node,” from your public node & it’s still available for people to use. In my instance, I have my primary node 46626 as a public facing node & I tie the ASL<->DMR Bridge to a private node 1999 or 1998. Take care & 73 de K4SQI!

Re: [DVSwitch] Analog_Bridge.ini
I guess I scanned through the op too quickly and didn't catch that.

You can't run USRP and Simple USB in the same node stanza at the same time. Each node stanza has a unique rxchannel.
It should look something like this:
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
rxchannel = SimpleUSB/usb_1998 ; SimpleUSB
Same box, no problem. Same node stanza, problem.

You mentioned something yesterday that created a question in my mind. You said USRP and SimpleUSB can't run together on the same box. I'm assuming that has something to do with those two channel drivers in asterisk. My install seems to be fine less the complaints about "digital sounding audio" but I'm running Analog_Bridge, MMDVM_Bridge and P25Gateway on the same Pi as an allstar node with URIx connected running DSP. It seems fine but does this have the potential to cause erratic behavior?

We are working to simplify and standardize the configuration files across all the Partner programs. Analog_Bridge.ini is one of the oldest and needs a little facelift to better match the other partners. Though some of the parameter names are changing, the old names will be supported for a while. If you are still using the older names, you will get a warning in the Analog_Bridge log. Your configuration will continue to operate as before. I have bolded the changes parameters Here is the updated Analog_Bridge.ini:

; 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.
