no more than one digital-to-analog signal conversion in the path from your ISP to your
modem. If more than one analog-to-digital conversion occurs, your connect speeds will
default to V.34 (33.6 Kbps). There may also be impairments on the local lines between your
ISP and your modem. These impairments can prevent or limit V.92 or V.90 connection
speeds. All telephone calls are routed differently, so you should try making your connection
several times. One way to test this is to dial into a long distance location. Long distance
lines are often much clearer than local lines. It is important to note that telephone
companies are constantly upgrading their systems. Lines that do not support 56K today may
support 56K in the near future.

Your modem must be connecting to a V.92 or V.90 server. A pair of 56K modems will not
connect to each other at 56K speeds.
