This may end up sounding like a really dumb question but... If all the lines in a neighborhood are being utilized and someone tries to call into that area to a phone that is NOT being used what (if anything) will happen? Will they get a busy signal? Thanks, --Bi//

Will they get a busy signal? I believe that they will get a re-order tone. This is a "fast-busy", which sounds like a busy signal but the cadence is (I think) twice as fast. This (or a recording) is the mechanism to indicate that all circuits are busy and to retry (or "re-order" later). -- Jack Bonn, <> Software Labs, Ltd, Box 451, Easton CT 06612 seismo!uunet!swlabs!jack

A classic example of the above scenario is an area near a high school and a majority of the students get home at 3:00 and want to call their friends. A well designed office will distribute lines from this area throughout the network. The respondant was correct, though, that if all circuit are used, reorder tone will result. Andy inhp4!ihlpf!ahl

Will they get a busy signal? Me and my friend who both work in the phone company and have experience with ESS happened to read this and before reading the followups decided that unless there was a problem with the office (poor load balancing), nothing would happen. That is, the incoming call would complete with no problem. If there were poor load balancing, some of the people in the neighborhood would start getting no-dial-tone or slow- dial-tone at times. On incoming calls to a very busy office with poor load balancing, callers could get re-order tone (120 ipm busy tone). -- Marnix (ain't unix!)
