Modem does not connect at
highest speed.
Line conditions in your area or in
the area you are calling may not
support the highest
connect speeds.
Have your telephone line checked by
your local telephone service provider.
Try dialing an alternate telephone
number for the service you are using.
Another device on your telephone
line may be causing interference.
Hang up an extension telephone and
disconnect any other devices that may
be using the same telephone line,
then redial.
The service or site called does not
support 56K or supports an
incompatible 56K implementation.
The standard internal modem
supports the V.90 ITU Standard for
56K modems with backward
compatibility to K56flex. To find an
Internet Service Provider (ISP) who
supports V.90 or K56flex protocols, go
to the Compaq Web site at
www.compaq.com.
There is noise on the telephone
line.
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.
