I'm trying to work on why PC-Tel modems suck connecting to our TC hub. I have a Compaq laptop with a PC-Tel built in. From home, I cannot even pass data to get authenticated unless I use an init string to turn off v.90. From the office, which is located in the same building as the telephone switch (we're an independent phone company), I get connected at 49k and can stay connected for hours at a time. Is it possible that increasing the modem transmit level could improve performance over the phone lines? Is there any chance this could interfere with other modems' connections? What is the optimal setting for transmit level? Should I be looking at a different setting? Wow, lots of questions, I know.
