Effect on dial up connection
due to additional phone equipment
A modem is typically used to send digital data over a phone line.
The sending modem modulates the data into a signal that is compatible
with the phone line, and the receiving modem demodulates the signal
back into digital data. There are more then one devices that can
be attached to the phone line long with modem. New phone equipment
such as Fax Machines, Answering Machines, Additional Extensions
or Home Networking equipment may be added to your phone connections.
Often these devices of one of these devices create issues for
your dial up connection. The problems can range from additional
noise on the phone line or failing connection.
Main cause of this kind of problems is improper installation
of one of the devices. If these devices are added to same phone
line that you use to access internet then it becomes very important
to see that each device is installed properly. Even the installation
of additional telephone lines run through various parts of the
house can be causing problems if they were not correctly installed.
Testing for these problems can be very easy. You may just temporarily
remove devices leaving one and removing other equipment to see
if the issue persists. If the issue has started after recently
added device then remove that device first and see if the disconnect
or noise problems gets rectified. One by one remove the application
from the assembly and see if the conditions improve. If a particular
device is creating issue then it will be revealed by this method.
You will need to reinstall it properly. If the issue persists
then there is a possibility that the device has gone faulty. When
testing for problems by disconnecting other equipment, it is very
important to remember that the power supply may have to be unplugged
but the phone cord attached to the connection jack should be temporarily
This type of problems also includes line equipment outside your
location. It may also happen that in some locations where the
telephone company has not upgraded their equipment and you may
have telephone line that has a dial up connection and other phone
devices installed. Here the old phone line will not support high
speed dial up connections very well or even at all.
On the other hand, if the telephone company does add some device
to the current set up then it may also cause problem. For example,
if a phone company is running low on phone lines it may decide
to install a device called a SLC. This device basically split
up a phone line channel into two separate channels in order to
accommodate the growing need for phone lines in your area. This
will have adverse effect on your dial up connection.
In this case, if you could be getting good speed consistently
and one fine day they could install one of these SLCs into your
local telephone lines setup doubling their available phone lines
but effectively cutting your bandwidth in half.
Taking precautions and maintaining your equipment constantly
will save you from most of the troubles.
