In Tridex SVT, program Direct Dialing 949 for button number 1, and Direct
Dialing 948 for button number 2 for this particular substation. Program
direct dial table number 1 for both channels in the SVT programming. 948
is the facility code to step through Program Distribution Channel Volumes.
949 is the facility code to step through Program Distribution Channels. The
Program Distribution Mode must be set to Mode A in order for this to work.
