If you have voice mail provided by your phone company, your dial tone may
be altered when messages are waiting. Retrieve your voice mail to restore
a normal dial tone.
Note:
If you are unable to retrieve the messages, you may want to add
five commas to the beginning of the number to be dialed. Each comma
represents two seconds. Therefore, adding five commas will delay the
modem connection attempt by 10 seconds. Since each ISP connection
may vary, you should insert as many commas as necessary to meet your
specific needs. Commas may be necessary if voice mail messages have
not been deleted before attempting to establish an Internet connection.
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.
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 connections. The V.90 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 technology at this time.
To achieve a V.90 connection, the following conditions must be met:
The server you are dialing into must support and provide a digital 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 analog-
to-digital 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-analog 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
such conversion occurs, your connection speeds will default to V.34+
or below. 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 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.
