FAQs
My
56K modem will not connect faster than 33.6k or 28.8k. What can
I do?
There are
many issues that can prevent a V.90 or K56Flex connection. As
modem speeds get faster, connections can become unstable. The
modem is designed to test for line conditions, and then select
the best speed to create a stable connection. Sometimes this results
in a slower connection. To get a V.90 or K56flex protocol connection,
your phone line must be of excellent quality.
My
modem speaker is too loud. How can I mute it?
Here are some
instructions to mute the modem in Windows 95 or NT. Go to Control
Panel / Modems. Highlight the modem and click on Properties /
Connection. Click on the "Advanced" button. Under the 'Extra Settings',
add the following: M
My
modem says that it is connected at 115K, but it is only a 56K
modem. How can this be?
CONNECTION
RATE
The connection rate is the rate at which your modem and the remote
modem connect, such as 28,800, 33,600, 40,000, 48,000 and 50,000
bps. This rate is determined by the modems when they connect.
Your modems connection rate will never be higher than your modems
rated speed. Other terms using the same definition include: Carrier
Speed, Line Speed, DCE Speed.
COMPUTER
RATE
The computer rate is the rate at which your modem and computer
communicate. You change this rate in your software. With your
modem, this rate should be higher than your connection rate, such
as 57,600, 115,200 or 230,400. The connection rate is much more
important than the computer rate. This rate is sometimes reported
instead of the CONNECTION RATE. Other terms using the same definition
include: Serial port Speed, Modem to Computer Speed, DTE Speed.
I
have heard about X2, KFlex and V.90. What is the difference?
When 56K modems
were first invented, no standard existed. As a result, US Robotics
developed 56K modems using its proprietary X2 protocol and Rockwell
International developed 56K modems using its proprietary KFlex
protocol. Now a universal standard has finally emerged, V.90.
Most 56K modems are flash upgradeable to the new V.90 standard.
