Does anybody > know what the precise difference is ? This is a loop current timing selector. It determines whether the answering machine will disconnect on a short loop current interruption or whether it requires a longer one. The longer one is used for call-waiting. This will prevent the machine from unceremoniously hanging up on a caller who is leaving a message if someone else happens to call at the same time. The shorter one will allow the machine to hang up at the slightest loop twitch and has the advantage of instantly disconnecting at the moment the caller hangs up. All of the above mainly deals with 1/1AESS switches. Most digital switches have no loop signal (CPC) on call waiting and you may set the switch to the non-call waiting position.
