Callsign Communication System 7 - DMR USER REPEATER Registration

CCS7 - what's that?
Explained :
"CCS" stands for "
Callsign Communication System". It was developed several years ago as an optimized alternative to the G2 callsign routing system.
CCS routing may be initiated based on callsigns, but also based on a numeric ID which may easily be entered by DTMF.
Using DTMF codes very quickly became the most common way.
When the CCS-Code was introduced for DSTAR callsign routing, nobody expected that the acceptance would be as high as we see it today.
At the beginning many people brought up arguments like "we have callsigns in amateur radio and do not need numbers", "the current G2 callsign routing is good enough" etc..
However, the system was setup first in the German language area where the DCS reflector system grew very fast and became the leading system.
DCS and CCS are closely connected, the callsign routing system CCS uses the DCS reflector mechanism to connect repeaters together for callsign routing.
CCS Callsign Routing basically connects 2 repeaters transparent together through a virtual reflector.
The DTMF system uses 4-digit numeric codes which provides about 9,000 CCS-IDs.
Users and repeaters share the same address space.
Towards end of 2014 it became visible that this address space wont be large enough for future development.
