# Description
|
||
|
|
|
||
|
|
This is the source code of P252DMR, a software for digital voice conversion from P25 to DMR digital mode, based on Jonathan G4KLX's [MMDVM](https://github.com/g4klx) software. Unlike the other cross mode utilities upon which this is based, this utility performs software transcoding between IMBE 4400x2800(P25) and AMBE+2 2450x1150(DMR).
|
||
|
|
|
||
|
|
You can use this software with MMDVMHost and P25Gateway, with the default UDP ports:
|
||
|
|
|
||
|
|
MMDVMHost(P25 Mode):32010 <-> 42020:P25Gateway:42010 <-> 42012:P252DMR <-> (DMR Master server)
|
||
|
|
|
||
|
|
If you want to connect directly to a XLX reflector (with DMR support), you only need to uncomment ([DMR Network] section):
|
||
|
|
|
||
|
|
XLXFile=XLXHosts.txt
|
||
|
|
XLXReflector=950
|
||
|
|
XLXModule=D
|
||
|
|
|
||
|
|
and replace XLXReflector and XLXModule according your preferences. Also, you need to configure the DMR port according the XLX reflector port, for example:
|
||
|
|
|
||
|
|
Port=62030
|
||
|
|
|
||
|
|
StartupDstId, StartupPC and Address parameters don't care in XLX mode.

# Building
|
||
|
|
|
||
|
|
This utility is not built with the other cross mode ulitities, and has 2 external dependencies:
|
||
|
|
|
||
|
|
imbe_vocoder https://github.com/nostar/imbe_vocoder
|
||
|
|
md380_vocoder https://github.com/nostar/md380_vocoder
|
||
|
|
|
||
|
|
With these dependencies installed, run 'make' from the source directory.
|
||
|
|
|
||
|
|
# Crosslink configuration
|
||
|
|
|
||
|
|
You can use P252DMR to link a [P25 Reflector](https://github.com/g4klx/P25Clients) to a DMR network (without using any RF link):
|
||
|
|
|
||
|
|
P25Reflector <-> P252DMR <-> any DMR Network
|
||
|
|
|
||
|
|
Install the P252DMR software at the same server where P25Reflector is located. Configure your [DMR Network] section (P252DMR.ini) as usual, depending on your preferred DMR network. Then, you only need to match the P25Reflector UDP port (Port in [Network], P25Reflector.ini) to P25 UDP port (DstPort in [P25 Network], P252DMR.ini).
|
||
|
|
|
||
|
|
For example, a common UDP port in P25Reflector.ini:
|
||
|
|
|
||
|
|
[Network]
|
||
|
|
Port=41000
|
||
|
|
|
||
|
|
Then you need to configure P252DMR.ini (example):
|
||
|
|
|
||
|
|
[P25 Network]
|
||
|
|
Callsign=CE1ABC
|
||
|
|
TG=10300
|
||
|
|
DstAddress=127.0.0.1
|
||
|
|
DstPort=41000
|
||
|
|
LocalAddress=127.0.0.1
|
||
|
|
LocalPort=41015
|
||
|
|
Daemon=0
