My modem sounds like it’s trying to connect to another modem but fails.
Possible solution:
You may have a poor connection. All calls are routed
differently, so try placing the call again.
Possible solution:
Make sure that the DIP switches on the bottom of your
modem are set correctly. DIP switches 3, 5, 8, and 9 should be in the ON
(down) position. See the diagram in the “Configuring the Courier 56K
Business Modem with DIP Switches” section in this guide for the correct
settings.
My modem isn’t achieving a 56K Internet connection.
Possible solution:
Our research has shown that the vast majority of
telephone lines can and do support V.90/V.92 connections. The V.90/V.92
protocol allows for connection speeds of up to 56K, 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.90/V.92 technology at this time. In order to achieve a V.90/
V.92 connection:
1.
The server you are dialing into must support and provide a digital V.90/
V.92 signal. Your ISP can provide you with a list of dial-up connections and
information on what those connections currently support.
2.
The telephone line between your ISP and your modem must be capable of
supporting a 56K connection and contain only one analog-to-digital con-
version. The 56K signal from your ISP begins as a digital signal. Some-
where 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 analog-to-digital signal conversion in the
path from your ISP to your modem. If more than one analog-to-digital con-
version occurs, your connection 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 connection speeds.
All telephone calls are routed differently, so you should try making your
56K connection several times. One way to test this is to dial into a long dis-
tance 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.

For a V.90 connection, your modem must be connecting to a V.90/56K
server. A pair of 56K modems will not connect to each other at V.90/56K
speeds.
