[time-nuts] OT: NTP server questions

[Robert Darlington]

Hi guys,

I'm looking to buy an NTP server for a field deployable server system.  I
currently have a Symmetricom SyncServer S250 which does more than I need.  I
am considering buying an S200 (same as the S250 but without the ability to
connect to an external frequency standard).  My gut feeling is I don't need
a rubidium oscillator or even an OCXO internally since we'd be going from a
power on to being used state in under an hour, outside of any kind of
temperature controlled environment.  Are there any manufacturers out there
besides Symmetricom that I should be looking at for something like this?
The unit we're considering buying is about $4k new and is inside of our
budget.

Thanks,
Bob
