in the case of you using a circuit (T1, DS3, ATM, ..) which your carrier 
transports over SONET, the best you'll see is a lost packet or ten.
(the actual switchover time is fast; the amount of data lost is dependent 
on the distance of the hop -- light 'in motion' is not recoverable).

in the case of you using a POS interface or similar, you may get APS 
notification, providing the ring that has failed is on the same element as you.
