Re: Connecting more that 2 Analog_Bridges #analog_bridge

If only it were so. In the diagram below (if I understand it) you have NXDN, DMR and YSFn all enabled. That's fine but NXDN is going to need to point it's TX and RX UDP ports at another mode (or Analog_Bridge)  But only one partner. MMDVM_Bridge does not mix all the modes and then output to AB. It's a one to one relationship. Look at DVSwitch.ini:

; Configure the DMR Partner
; Audio format is AMBE 72 bit
[DMR]
Address = 127.0.0.1             ; Address to send AMBE TLV frames to (export)
TXPort = 31100                  ; Port to send AMBE TLV frames to (export)
RXPort = 31103                  ; Port to listen on (import)

; Configure the D-Star Partner
; Audio format is AMBE 48 bit (DSAMBE)
[DSTAR]
Address = 127.0.0.1             ; Address to send AMBE TLV frames to (export)
TXPort = 32100                  ; Port to send AMBE TLV frames to (export)
RXPort = 32103                  ; Port to listen on (import)

; Configure the NXDN Partner
; Audio format is AMBE 72 bit
[NXDN]
Address = 127.0.0.1             ; Address to send AMBE TLV frames to (export)
TXPort = 33100                  ; Port to send AMBE TLV frames to (export)
RXPort = 33103                  ; Port to listen on (import)

; Configure the P25 Partner
; Audio format is IMBE 88 bit
[P25]
Address = 127.0.0.1             ; Address to send AMBE TLV frames to (export)
TXPort = 34100                  ; Port to send AMBE TLV frames to (export)
RXPort = 34103                  ; Port to listen on (import)

; Configure the Yaesu Fusion Partner
; Audio format is AMBE 72 bit
; Audio format is IMBE 88 bit
[YSF]
Address = 127.0.0.1             ; Address to send AMBE TLV frames to (export)
TXPort = 35100                  ; Port to send AMBE TLV frames to (export)
RXPort = 35103                  ; Port to listen on (import)

For a DMR to NXDN bridge it require to "cross connect the DMR and NXDN ports like this:

[DMR]
Address = 127.0.0.1             ; Address to send AMBE TLV frames to (export)
TXPort = 31100                  ; Port to send AMBE TLV frames to (export)
RXPort = 31103                  ; Port to listen on (import)

[NXDN]
Address = 127.0.0.1             ; Address to send AMBE TLV frames to (export)
TXPort = 31103                  ; Port to send AMBE TLV frames to (export)
RXPort = 31100                  ; Port to listen on (import)

To mix everything in analog, you will need an ASL node for each mode. That's 5 copies of AB and 5 ASL nodes on the server. But I'll say again, you do not want to convert each mode to analog due to the loss of quality as compared to like vocoders.

Would this seem like a appropriate all mode solution? Or am i over complicating this? I am not sure on the DStar
