>I was curious how people had the timing setup for their T100P and Total
Access 750.
I pull timing from the ta-750 in the un-scientifc belief that the
timer is more accurate than the low end t100p crystal
span=1,1,0,esf,b8zs

> Should I set the channel bank to provide timing or receive timing?
My Atlas 550 provides timing and I set my zaptel.conf to:

 

 span=1,0,0,esf,b8zs

 

Never had a red alarm, ever.

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.

The former is true. Should have been 1. My apologies. Posted as plaintext
per your requirement.
