Dialing speed (rotary (DP) or DTMF, no matter which) has absolutely NO effect on call completion success, the only exception being if your dialed digits are too slow or too fast for detection (i.e., < 6 || > 15 pps DP or > 10 digits/sec DTMF). If you are in a crossbar office, you are effectively "offline" when dialing; your dialed digits are being decoded and stored in an `originating register' (OR). Only when the OR detects the completion of a dialing sequence (or abort of same through a timeout) is the call routed to the `marker' for route section and transmission through the DDD network. Also, the method of station dialing - DP or DTMF - has absolutely NO bearing on the signalling (i.e., digit transmission) to the destination office. === Larry Lippman @ Recognition Research Corp., Clarence, New York === === UUCP {decvax,dual,rocksanne,rocksvax,watmath}!sunybcs!kitty!larry === === VOICE 716/741-9185 {rice,shell}!baylor!/ === === FAX 716/741-9635 {AT&T 3510D} ihnp4!/ === === === === "Have you hugged your cat today?" ===
