Q.
What is the biggest factor in my connection speed?
A.
Since all signals transmitted through a standard dial-up connection are analog,
the smallest bit of interference on a telephone line can cause general connection
problems. The number one contributing factor to slow connection speeds is weak
signal quality on the phone lines and/or background noise on the line. Unfortunately,
there is only limited troubleshooting that can accommodate poor line quality.
Initialization strings for you modem that slow down connection speeds can sometimes
work when background noise on the phone line is causing disconnections.
If you are experiencing
a maximum connection speed significantly lower than what both your modem and
your ISP's modems support, there is a good possibility that there are old copper
wires limiting that connection speed. The maximum connection speed anyone can
ever achieve is 54,333 bits-per-second. Currently, FCC regulations prevent all
devices attached to the telephone network from exceeding a certain power output.
As a result, many telephone companies have had to scale back the power output
on their phone lines. That has a direct effect on the speed at which a modem
can transfer and receive data. Currently, default server modem limits are set
to 54,333 bits-per-second. The minimum data transfer rate, on the other hand,
is only guaranteed at 14,400 bits-per-second or higher. If you are experiencing
connection speeds below 14,400 and have gone through extensive troubleshooting
with your ISP, you should contact your local phone carrier and make them aware
of your troubles.

Q.
Why does phone line noise affect my connection speed?
A. It
all has to do with how computers understand "data." Everything that
your computer does, stores, or displays uses binary data, which is a 1 or a
0. Simply put, a 1 means that electricty is flowing through your computer's
processor, and 0 means that there is no electricity flowing through the processor.
The switch is on or the switch is off. A modem connection to the Internet has
an analog portion that cannot transmit the on and off states of binary data.
Analog phone lines have electrical sound signals that your telephone turns into
sound waves, which are then sent to your ear where you "hear" what
is being said over the telephone.
Your computer
doesn't understand electrical sound signals. It only understands
1's and 0's. Computers have to Modulate the digital signal that
computers understand (1's and 0's) into a series of electrical sounds
sent over your telephone lines. Your modem then has to Demodulate
those electrical sounds on the phone lines back into a digital signal
that is understood by your computer. The Modulating and Demoduating
is where you get the term Modem.
Here's where line noise
comes in to play. When data travels along an analog phone line, you can pick
up a phone and actually "hear" it with your own ears. Your modem also
has to "hear" this data, so any noise on the phone lines can mask
the data that your modem wants to hear. In order for your Internet connection
to work properly, your modem needs to hear the data perfectly. If it can't hear
it very well, it will slow its speed down so it has more time to decode the
electrical sounds on the phone line into the digital signal that your computer
understands.
If the noise
on your phone line becomes too bad, your modem can actually disconnect
altogether. You could also experience problems gettings connected,
as your modem and Blue One's modems may not be able to hear
the handshake properly.

Q.
What is the modem handshake?
A. The
modem handshake is the computer term for two modems greeting each other
when one modem calls the other to establish an Internet connection.
If you have your modem's speaker volume turned up, you will be able to hear
the modem dial out and then make squawks and tones like a fax machine. Those
squawks and tones are the modem handshake. During
the handshake, the two modems, one being the user's modem and the other being
the ISP's modem, negotiate which protocols they will use to transfer data. This
would be like negotiating the rules of engagement. The two protocols that Blue One
modems support are V.90 and V.34.
The V.90 protocol is what
allows you to connect at the higher 56k speeds. It assumes that the only analog
connection between you and the Internet is between your modem and your local
telephone company. If there is more than one segment of your connection to the
Internet that is analog, the V.90 protocol cannot be used. V.90 connection speeds
can range from 28,800 bits-per-second to 54,333 bits-per-second, though average
56k speeds fall between 36,000 bits-per-second and 48,000 bits-per-second.
The V.34 protocol allows
you to connect up to 33,600 bits-per-second. It assumes that there are two or
more analog segments of your connection to the Internet.
During the modem handshake,
Blue One's modems will attempt to transfer data using the rules set up
by the V.90 protocol. In order for that to work, your modem must support the
V.90 protocol. If your modem does not support the this protocol, then Blue One's
modems will try to use V.34, which will limit your connection speed
to 33,600 bits-per-second.
When
trouble-shooting a connection problem, listen to the modem handshake. If it
seems to repeat certain tones and squawks, your modem may be having problems
communicating with Blue One's modems, or having a problem agreeing on
which connection protocols to use.

Q.
Which connection protocols does Blue One support?
A.
Blue One supports the V.90 protocol for 56k speeds, V.34
for connection speeds up to 33,600 bits-per-second, and V.34bis for connection
speeds up to 14,400 bits-per-second. Blue One also supports older protocols that
work with older modems, which most people do not use.

Q.
What is RNAAPP?
A.
RNAAPP stands for Remote Network Access Application.
This is the core application of Windows-based Dial-up Networking,
which is the software that allows people to dial and connect to
the Internet using a modem.
On occasion,
RNAAPP.EXE will get locked in your system memory causing difficulty
while connecting to the Internet. RNAAPP is understood by your Operating
System as being an "Active Connection" and thus will hinder
your computer's ability to establish another connection. This can
sometimes be remedied by restarting the computer. In most cases,
it is necessary to remove RNAAPP.EXE from your task list of running
programs. You can do this by pressing Ctrl+Alt+Delete simultaneously
on your keyboard to open the Close Program or Task Manager
window. Once the task list is opened, click on RNAAPP.EXE
and click the End Task button. Restart the computer and check
for RNAAPP once fully rebooted. If RNAAPP continues to cause problems,
you may want to consider re-installing the Dialup Networking Windows
component.
Note
to most users: you may need your Windows installation CD to do this.

Q.
What is Winsock?
A.
Winsock is the supporting program interface between a Windows Operating
System and any Internet application. Winsock is the Microsoft Windows version
of a socket application (hence the name "Winsock). This program runs "between"
your Internet application, such as a browser or email client, and the networking
component TCP/IP protocol. Since Winsock operates "between" the Internet
application and the TCP/IP protocol, it can cause data transfer issues without
the user knowing of any problem. Typically, you will find Winsock errors after
all other forms of troubleshooting an Internet connection problem have been
exhausted.

Q.
What does "ripping and reinstalling" mean?
A. This
is a rather involved process of uninstalling and reinstalling (almost) every
Windows component related to your dial-up Internet connection: Dial-up Networking,
TCP/IP protocols and adapters. This process may also involve re-installation
of modem firmware, which due to liability reasons, is the responsibility of
the end-user.
Most newer computers will
have a back-up copy of your modem's firmware on the hard drive. If your modem
is plug-and-play, your Windows installation CD should have the proper software
to run your modem. You may also have a System Restore disk, which if used, will
wipe out all saved data on your computer and restore it to the condition it
was in when you first started using it. If need be, you can always contact your
computer's or modem's manufacturer and have them send you a disk with the latest
software for your modem.
If you are unsure how to
do this, please contact technical support at 721-2583.

Q.
What is an init string?
A.
An init string is a command to your modem that can enable and disable connection
protocols or limit your connection speed. Some connection protocols include
K56Flex, V.90, X2, and V.92.
