All there is to see in the errors you sent is that the sonet interface 
went down, and by the looks of it I'd say because of external problems 
(clocking/synch comes to mind) but without more info that's pure 
speculation. Where there any SONET alarms prior to the 
SNMP_TRAP_LINK_DOWN message...? AIS, LOS, RDI....?
