I had kind of assumed the same thing; however, I was hoping I could T off a feed from the GPS antenna to a new receiver with different outputs, which we would purchase to provide time-of-day synchronisation rather than 1/2000 second synchronisation. It seems that there are a number of receivers that will do the job, but people are mentioning async interfaces and ethernet interfaces, and I am confused :) More random off-topic questions: a GPS synchronised clock is stratum-2, right? The caesium clock which provides synchronisation to the GPS is stratum-1? Sorry for the wasted bandwidth. Feel free to divert me privately to a FAQ on this, rather than cluttering up -hackers (I looked but couldn't find one). > [ML] * I think it's H1 I'm talking about: 30+2 channels of > 64kbps.
