My modem isn’t achieving a 56K Internet connection.

The V.92 and V.90 protocols allow for download speeds of up to 56K and

the V.92 protocol adds upload speeds of up to 48K, but line conditions may

affect the actual speeds during a given connection. Due to unusual

telephone line configurations, some users will not be able to take full

advantage of V.92 or V.90 technology at this time. In order to achieve a V.92

or V.90 connection:

• The server you’re dialing in to must support and provide a digital V.92

or V.90 signal. Your ISP can provide you with a list of dial-up

connections and information on what those connections currently

support.

• The telephone line between your ISP and your modem must be capable

of supporting a 56K connection and contain only one digital-to-

analogue conversion. The 56K signal from your ISP begins as a digital

signal. Somewhere between the ISP and your modem, there will be a

digital-to-analogue signal conversion so that your modem can receive

the data. There must be no more than one digital-to-analogue signal

conversion in the path from your ISP to your modem. If more than one

analogue-to-digital conversion occurs, your connect speed 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.
