- Re: Connection problems w/ V.32 modems
-
- The modems should be able to connect over voice quality dial-up lines.
- You should not need a special data line. There are a couple of
- questions I have for you:
-
- A. What is the exact model of the modems you are
- using?
- B. What are the serial numbers? I can see what vs.
- EE prom is currently in the modem.
- C. Are you using error correction on the modems?
- D. Did you try connecting at 4800 baud?
-
- It is possible since you are connecting over a Fiber line that the
- modems are over driving each other preventing you from getting
- connected. There is an undocumented register that can be changed.
- That register is S20. Try changing this register to a 8.(ATS20=8&W)
- This will boost the transmit level to a -8db. The factory setting is a
- -10db. It is not advisible to go any stronger than this on a dial-up
- line. If this makes it worse change the S20 register to a 12 (ATS20=12&W).
-
- If you have any questions Please give me a call or respond via mail.
- The hours here are 8:30 to 5:00 cst.
