[ntp:questions] Testing NTP disciplining of a OCXO

Hi,
we managed to import NTP to a platform with a OCXO as ascillator.
The clock is generated by a counter of the 26MHz OCXO frequency.
We are able to correct both offset (which is added to the counter) and
frequency (through a DAC).
We require to mantain the frequency drift of our OCXO within 100ppb (we
do not really care about phase, a part to provide NTP with correct
timestamps), I would like to know which NTP parameters should be
modified (if any) in order to provide this grade of service.
Once we got hold of a decent NTP server (a linux PC using pps from a
stable source) we will start to test out system. Do you have some
suggestion on the best way to test our system?
Thank you,
Mauro
