Utilizing V.90 Technology

All V.90 modems are analog line devices. The following

figure shows when you can and cannot achieve 56 Kbps.

• V.90 modems can receive data at rates up to 56 Kbps,

provided the data is being transmitted by a digital

modem on a digital (e.g., T1 or ISDN) line.

• V.90 modems can send data over analog (twisted

pair) phone lines at a maximum rate of 33.6 Kbps—

even if communicating with other V.90 modems.

• The actual data rate achieved depends on the age

and condition of the analog phone lines, and may be

lower than 33.6 Kbps.
