[olug] NTPd w/modem support

[Vincent.Raffensberger at dtn.com]

If you're in a large commercial building or data center, plan to run an 
antennae outside for it.  Many things can interfere with the signal and 
you wouldn't want to troubleshoot that years from now.  The placement of 
an UPS or rack could interfere...
MasterClock, TrueTime and Zyfer are the big brands.  If you have the 
budget, I'd get an appliance like the Zyfer.

Do you have a brand or model number for such a card?

Thanks to all for the ideas!
