DMRlink/bridge_rules_SAMPLE.py

'''
The following is an example for your bridge_rules file. Note, all bridging is ONE-WAY!
Rules for an IPSC network indicate destination IPSC network for the Group ID specified
(allowing transcoding of the Group ID to a different value). Group IDs are specified
as hex strings.

The IPSC name must match an IPSC name from dmrlink.cfg.

The example below cross-patches TGID 1 on an IPSC network named "IPSC_FOO" with TGID 2
on an IPSC network named "IPSC_BAR".

THIS EXAMPLE WILL NOT WORK AS IT IS - YOU MUST SPECIFY NAMES AND GROUP IDS!!!

NOTE: Timeslot transcoding does not yet work (SRC_TS) and (DST_TS) are ignored

def id(_id):
    # Create a 3 byte TGID or UID from an integer
    return hex(_id)[2:].rjust(6,'0').decode('hex')
