Proper symantics: timing is "always" encoded into a T1/E1 transmit
signal. You can't disable it.

"Clock Sync" on the other hand is a setable option. If the 750 is providing
fxs interfaces to phones, then set the 750 to receive sync from the T100P.
In the majority of cases (regardless of whether fxo or fxs interfaces are
installed), channel banks should be syncing from your asterisk box.
