# This is a sample application to bridge traffic between IPSC systems. it uses
|
|
# one required (bridge_rules.py) and one optional (known_bridges.py) additional
|
|
# configuration files. Both files have their own documentation for use.
|
|
#
|
|
# "bridge_rules" contains the IPSC network, Timeslot and TGID matching rules to
|
|
# determine which voice calls are bridged between IPSC systems and which are
|
|
# not.
|
|
#
|
|
# "known_bridges" contains DMR radio ID numbers of known bridges. This file is
|
|
# used when you want bridge.py to be "polite" or serve as a backup bridge. If
|
|
# a known bridge exists in either a source OR target IPSC network, then no
|
|
# bridging between those IPSC systems will take place. This behavior is
|
|
# dynamic and updates each keep-alive interval (main configuration file).
|
|
# For faster failover, configure a short keep-alive time and a low number of
|
|
# missed keep-alives before timout. I recommend 5 sec keep-alive and 3 missed.
|
|
# That gives a worst-case scenario of 15 seconds to fail over. Recovery will
|
|
# typically happen with a single "blip" in the transmission up to about 5
|
|
# seconds.
|
|
#
|
|
# While this file is listed as Beta status, K0USY Group depends on this code
|
|
# for the bridigng of it's many repeaters. We consider it reliable, but you
|
|
# get what you pay for... as usual, no guarantees.
|
|
#
|
|
# Use to make test strings: #print('PKT:', "\\x".join("{:02x}".format(ord(c)) for c in _data))
