Now you've got me utterly confused ... So, in layman's terms, if I connect a T100P to a circuit provided by the Telco, and the Telco says that they will provide timing, I have to put WHAT? span=1,0,0,esf,b8zs,yellow this means '0' this span is not a sync source, i.e. the Telco will provide my 8kHz. Could one use '2' with impunity (span=1,2,0,...)? I am still not clear under which circumstances one should use '0' versus '2'. WW
