Solution
Have your telephone line
checked by your local
telephone service provider.
Try dialing an alternate
telephone number for the
service you are using.
Hang up an extension
telephone and disconnect
any other devices that may
be using the same
telephone line, then redial.
An internal modem supports
K56flex.
To find an Internet service
provider (ISP) that supports
K56flex, go to the Compaq
Web site at
www.compaq.com.
The 56K protocol of an
internal modem will fall back
to lower speeds if the
telephone line is too noisy
for a high-speed
connection.
Try using another telephone
line.
The 56K protocol requires
that the telephone line
contain no more than one
analog-to-digital conversion.
Try connecting from an
alternate site.
