You may get gaps where frames are discarded, this will be across all timeslots
so an individual loss isnt a lot of data, you'll probably get away with the odd
one but if you get too many and the T1 realigns it could restart and you could
see the whole T1 go down and up..
Not sure how this works in the US with such diversity available but in the UK
telcos generally derive sync from another one so most of them are on the same
clock source..
