JS> Who told you that??? JS> You obviously haven't been keeping up with modern modem technology have Yes, I have. I used to conduct a series of datacommunication technology seminars for one of the leading mail order suppliers of datacomm hardware. The current bandwidth of the standard landline phone line is still 2400 Hz, meaning that there can be no more than 2400 discrete signal events per second on a phone line. Since the term "baud" means "discrete signalling events per second" the maximum baud rate of any modem is 2400. However, with imaginative encoding techniques, it is possible to pack more than one bit of data into each signal event. That's how V.32 modems can transport 9600 BPS (Bits Per Second) in 2400 baud, V.32bis modems can transport 14.4 KBPS (Kilobits per second) in 2400 baud, and V.34 modems can transport up to 28.8 KBPS in 2400 baud. Throw in data compression with V.42 and/or MNP 5, and the bps throughput can go even higher. But regardless of how high a bit per second rate can be achieved on a standards, 2400 baud phone line, the baud rate remains 2400. I realize that many people commonly misuse the term "baud" when they really mean "bps", and that's usually no big deal. But when the topic is a technical discussion of communication technology, accuracy becomes important. * OLX 2.1 TD * Give, & you might receive.

WN> -> WN> I was referring to the connect speed of the modem itself. Then the connect speed would be 12000 bps, not 12000 baud. Baud and bps are NOT the same thing, though people often use the terms interchangeably. Most of the time that's no big deal, but it is if you're trying to explain something technical with any degree of precision. * OLX 2.1 TD * Good gun control is a tight pattern. --- RG 05-11/CDRMAIL 103 * Origin: LOTL * (412)346-3592 * RGSNet PA Host * V.34+ (1:129/230) --------------- FIDO MESSAGE AREA==> TOPIC: 223 CELLULAR Ref: DAK00000 Date: 06/15/96 From: CONRAD SIAO Time: 11:22am \/To: BRIAN LINGARD (Read 7 times) Subj: Re: CLONED BL> Interesting how the illegals grab your esn and such.

Since there are only 2 carriers in any given area, you need to find out how those in your area think about the two carriers serving your area and choose accordingly. Trying to compare something like "Cellular One" is difficult since it is no more than a franchise name. Although the companies using the name must subscribe to a particular set of standards, there is a wide variety of implementation of those standards. Most of the wire-line companies use their parent companies name. Only one that I know of uses their own name on both sides ("A" & "B") and that is United States Cellular.
