Either calls complete or they don't-- the switches do not queue them up in long lines. I didn't hear any reports of network congestion. Bryan Richardson AT&T Bell Laboratories [Moderator's Note: My experience that day was that while some calls got rejected with fast busy signals, others simply got lost in transit. That is, they wandered away into dead silence, no ring/no busy. After a waiting period of maybe fifteen or twenty seconds, I'd simply abandon the call and dial over. PAT]
