raymo Tl Posts: 5 USA | Posted - 10/21/2004 8:14:59 AM ![]() ![]() ![]() Richard, Thanks for the great site!!! I have a USR modem, internal, 5699B. I have been having a lot of trouble connecting. My ISP used to have two servers - one for v.90 and the other for v.92. They just got rid of the v.90 server and now I can barely connect. I have the Control center and have tried different strings and can just connect but the data transfer is very slow. I have been using hyperterminal on my pc. A strange thing is happening. When I type commands the typing doesn't show up but if I hit enter the command is initiated and I get the results. I have been have a lot of trouble in the past years. It's not always been a USR modem but they seem the worst. I know I have a bad line and am probably limited to 28k at best. That would be better than what I am getting now. Can you recommend an internal modem that would be similar to the laptop modem? It is using the 1641B chip from Lucent. Thanks in advance. Ray |
v.Richard Tl Posts: 6222 USA | Posted - 10/22/2004 2:42:40 AM ![]() ![]() ![]() ![]() Ray, The Hyperterminal part is easy - the init string on your modem has echo off - if you type ATE1 in Hyperterminal and hit enter, you'll get back OK, and then everything you type will echo back. You could try disabling 56k on the USR modem via init string of Also - post your post-call diagnostic results including As for a modem similar to the 1641 - Aloha! Richard. |

raymo Tl Posts: 5 USA | Posted - 10/22/2004 5:58:06 AM ![]() ![]() ![]() Richard, I tried the same thing with my laptop with the lucent chip. It asks me for my login id and passoword. I disconnect and enter ati6i11y11 and I get an error E49E. I wanted to compare the two but couldn't get the proper response. Is there a different string for the other modem? Note that the USR modem connected but my ISP did not ask for the username and password. Ray |
v.Richard Tl Posts: 6222 USA | Posted - 10/22/2004 3:38:19 PM ![]() ![]() ![]() ![]() The USR & Lucent chipsets don't support the same diagnostic commands - Lucent has ati11 but does not give as much information. The receive levels you are getting according to the USR modem are well outside telco specs; either there's something wrong with the modem, your inside wiring or some device connected to your line, or something wrong between the demarc and telco office.

raymo Tl Posts: 5 USA | Posted - 10/22/2004 4:41:24 PM ![]() ![]() ![]() Sorry, I should have given you more info. I have nothing else on that line - it is dedicated to the modem. Also, I wired it with Cat-5 wire. I have had the telco out here several times. The last time they had to replace something they refer to as a "slick" which from what I understand is the interface between my analog cable and their FO (fiber optic) cable. After they replaced it I was able to connect into the v.92 server sporadically but was successful connecting to the v.90 server but was limited to a 21600 connection. They told me that this was due to the type of slick. I always connected at 21600 but for some reason I think I was actually downloading faster than that. Are v.44 protocols the same as v.92? I noticed that in your site you write them as "v.44/v.92". I am at the end of a three mile long cable. The FO goes to a small "shack" about three miles away and my cable pair goes there. It seems that I have a fairly good connection with the lucent modem. I wish it was better, though. Should I just go ahead and buy a new modem? Are there really that many differences between modems? I thought they were pretty much the same. Is there a modem that will give me a stronger signal? Thanks for all your help. You have a great site and I am slowly learning about modems from all the information you have.

v.Richard Tl Posts: 6222 USA | Posted - 10/24/2004 6:24:24 PM ![]() ![]() ![]() ![]() "Slick" = SLC = Subscriber Loop Carrier - this is a way for telco to concentrate many telephone lines together on same cable, and, telco is correct that it will impair modem performance. I don't think there's much you can do about this (other than pack up and move to a different location that has different telco/lines). There shouldn't be a big difference among different types/brands of modems - the telco facilities are what's causing the problem. V.44 is an 'improved' compression protocol - while it's not part of V.92, it was introduced at the same time as V.92, so V.44 is only found with V.92 modems. V.44 compression can occur even if your V.92 modem doesn't make a V.92-high-speed connection, so long as your ISP also supports V.44 (same thing - you'd need to call a V.92/V.44 modem at the ISP to get V.44). Aloha! Richard. |
raymo Tl Posts: 5 USA | Posted - 10/24/2004 7:15:06 PM ![]() ![]() ![]() I am connecting with the LT modem at a fairly good rate. Same lines and everything. The lines clearly cannot handle the new compression rates. Interesting note. I have a PC with a Best Data modem. I tried installing it and using the Best Data installation disk. It crashed my hard drive. This is the secon time this happened. The first time I put it down to a bad hard drive. This time I am certain the software screwed up my C drive. I have reformatted and now must reload everything. The disk is titled Best Data 56K V.92 PCI Modem. It is the 56HP92-PCTrev2. I know this sounds crazy but this modem worked fine in my secondary PC but I don't think I used their installation software I just downloaded the driver and installed it through the hardware installer on 98SE. Back to the drawing board. It's a good thing I just got this laptop up and running. Thanks, Ray |
