What is the MF>difference between Cat 3 and 5? Basically the difference between the Cat "x" is the amount of twists per foot(there's more to the specs if you REALLY want to know). The more twists, the higher the noise rejection of the cable. Cat 3 is adequate for 10mps Ethernet, while Cat 5 is required for 100mps Ethernet. Shielding will attenuate the the signal when used in a high speed network, that's why you use UTP. In a phone application you could used a shielded cable, but only if it's properly grounded. I wouldn't recommend it due to the added cost. It's easy enough to avoid noisy things in a house. Try to route your cables away from electric motors, fluorescent lights, speakers etc. Also try to keep the polarity correct, Check my "Tip & Ring Question" post for information. --- GEcho 1.00 * Origin: The Boneyard!

Well, we haven't talked since the beginning of March. So, this is to bring you up-to-date on my Logicode 33H-P-CL Plug-n-Pray internal modem. If you will recall I had two major problems with this modem and you and others on this echo suggested many fixes, none of which had any effect! The two problems were: 1) No sound was being produced for the BUSY or RING condition. The DIAL and NEGOTIATING generated noise and were completely audible. 2) I could not generate a DCE CONNECT speed message. Whenever I used the AT command "W2" the data screen just froze and required an ATH to hang up. I tried three different comms programmes and many different BBSs, all with the same result. I was only able to use "W0" (default) or "W1", both of which generated DTE speeds which of course were useless pieces of information as I already knew that I had the DTE speed set to 115,200 baud. After many e-mails and 4 phone calls FROM (note the FROM) Logicode in California, their final comment was words to the effect "... it sounds as if you have a defective modem and as we have a lifetime warranty on this equipment, please send it back to us for replacement ...". I explained that I would prefer because of Customs, etc. if they would just send me a new chip. They immediately agreed and I received the chip in the mail yesterday. I spent 20 minutes swapping chips and my "W2" command now works perfectly and I am able to display my DCE speed!! The sound has not been fixed but this is so minor (I have my sound turned off anyway) that I could care less! The only other significant difference showing up with the new chip is that it takes approximately 10 seconds longer to negotiate a connection ... this is reflected in the S7 register which has been increased from 50 to 60 seconds default. What I did want to do was to thank you and the others on this echo for the many excellent suggestions as to how to rectify my problem. I also wanted to praise the Logicode people for their excellent response and service! If USR had even been 1% as responsive with all the problems I had with my 14.4 internal Sportster ... in fact I couldn't even get them to respond at all!!! I have used this modem now for almost 4 months and have had two 28,800 and four 33,600 connects with another 500+ being at 31,200. My downloads average 3520 cps with not a single retry or error yet! As far as the FAX part, it works perfectly for send and receive. The only setting I have had to change from the factory default is the "W2" and "M0" commands and I just use ATZ as my init string for both data and FAX. I paid $99 (Can) and now they are available from Future Shop here in Richmond, B.C. for $69 (Can) after rebate ... IMHO they are well worth $169 with the solid performance and superb support from Logicode!
