TO MODIFY SET-UP DURING A CALL
These facilities are codec dependent. Not all options are meaningful with all codecs. If an
unavailable selection is made, the equipment will try to revert to an available mode.
When a call has been successfully connected and the RED LED is on, it is possible to force the
codec parameters. It is possible to change the encode algorithm, the sample rate and the data
rate. This is simply done by pressing the 'Grey' key 1,2 or 3 times. If pressed once the encode
algorithm can be changed. If pressed twice the sample rate can be changed and if pressed three
times the data rate can be changed. In each case you are only given a few seconds to make a
change before the option is aborted. The '< and >' keys are used to scroll through the options.
The option in view when the system 'times out' is the selected option. Available options are:-
ENCODE ALGORITHMFollow Decoder, G722, MPEG or APTX
SAMPLE RATEFollow Decoder, 16, 24, 32 or 48 KHz
DATA RATEAutomatic, 56 or 64 KBits/Sec
