Modem Pool FAQ
Q. Why can't I connect at 56kbps?
- Actual 56k connections are not permitted under regulations set by the Federal
government and telecommunications agencies. The industry standard is 53.3kbps.
- Quality of the telephone lines between the user's location and the Virginia Tech
modem pool: line noise causes a decrease in the rate of data transfer.
- User's modem may not be running on the V.90 standard. Standards such
as 56kFlex and X2 will not connect at 56kbps.
Q. Can I use two analog modems at the same time to get a 112kbps connection?
- No: Virginia Tech does not support PPP Multi-link
for analog modems.
