Dial up Connection Speed
Data transmission speed is considered as the
most important aspect of the dial
up connection. A common misconception many people believe
is once you connect to your ISP at a certain speed it remains
that speed the entire time you are connected. This is incorrect
assumption. The truth is that the speed may vary over a certain
period of time. The speed any go up or down or sometime it may
come to hold for a certain period of time and then resume.
No matter what your modem reports to you as your connection speed
it may not be the true speed. Both phone line quality and modem
type play a major part in the actual data throughput you receive
when downloading data from the Internet. If the phone line is
of good quality then the data will flow at high speed else it
may not reach a high speed or go down due to errors. Similarly,
different modems can support different speed. Basically overall
speed depends upon overall quality of the connection hardware.
However, throughput is more important than connection speed.
Most of the dial up users would have noticed that during the
initial connection process, the modem makes hissing and screeching
sounds and then it goes quiet. The hissing and screeching is called
training or synching. It is during this part of the connection
process that your modem establishes connection with ISP’s
modem and they are talking to each other to figure out at what
speed they can reliably send and receive data to one another.
After this process is completed, operation system shuts off the
modem's speaker so you will not listen to all the other noise
If the modem detects any change in the phone line conditions,
then it will go through the training or synching process again.
While it is retraining, no data will flow through the connection
which is why sometimes things just seem to stop working and the
modem lights does not flash. In most cases, the modem will start
sending data again after it is done with the retraining process.
This would usually take anywhere from 15 to 30 seconds, sometimes
it will disconnect if the retrain attempt failed.
Different modems have different ways of handling phone line noise
and retraining. Some modems will connect lower and then as time
passes it will slowly work its way up. Some other modems may connect
high and then train down over the duration of the call. Windows
only reports the connection speed you initially connected. Unfortunately,
there is no real way for you to know what your throughput is using
that information. Instead one thing you can do is get a program
that monitors your incoming and outgoing data through the modem
in real time. If your throughput is not good then probably you
will need to check you modem and phone lines.
