command code sequence
DTMF Dual-tone multi-frequency signaling
Is used on the DSTAR network to quickly and simply switch a repeater or
hotspot from one reflector to another or to enquire the status.
The table below is a quick reference how to use DTMF on the
XRF, and REF reflectors.
For those using the latest CCS call routing system, remember that to
disconnect it's DTMF "A". Otherwise you will stay linked, and will
follow your contact around the system.
My thanks to Johnston Dixon GI0BFO for putting this together.
How to use
The examples below are fairly self explanatory. However on the DCS
reflectors, each of the reflectors has up to 26 nodes or groups A -Z.
DTMF can only handle letters A -D, hence once you get to DCS001E the
DTMF becomes D105, F becomes D106 etc.
NB dependent upon which software your repeater and or simplex gateway
is running, you may have to unlink if you wish to switch to another
node on the same reflector.
IE if you wish to change from DCS005B to DCS005Q you would first have
to unlink, then link. If changing from DCS001B to DCS005Q (ie different
reflectors) there is no need to unlink.
This is not cast in stone, as mentioned it is dependent upon which
version of the linking software your node is running.
You will simply have to experiment.
Common DTMF commands
Disconnect = #
Status = 0
Disconnect CCS call routing = A
Reconnect to default connection = **
DCS001A = D1A = D101
1D = D1D = D104
DCS005A = D5A = D501
5B = D502
6Q = D617
X-Net XRF 10B = B10B
X-Net XRF 21B = B21B
REF 006 C = *6C
REF 005 A = *5A
