Dialing from Home
When dialing from home to the campus -- expect trouble; usually
you are not disappointed. For those dialing from home, here are
some unique problems to watch out for:
- If you have an extension phone in the house and someone tries to
use it (not knowing you are on with your computer) you will get
errors and most likely be disconnected from the computer you are
logged into.
- Another common problem dialing in from home is call
waiting,which alerts you that another call is coming in. Again,
this signal will cause garbage on the line and usually disconnect you
form the central computer. There is an option offered by the local
telephone companies that lets you deactivate call waiting
(*70) while you are on the computer.
- A very elusive problem is simple noise on the telephone line,
caused by conditions within the telephone system. The only thing
you can do with line noise is hang up and dial again. Many times the
problem will go away because the circuit selection when dialing is
random.
- Finally, remember that you are paying for voice-quality line from
the local telephone company rather than a data-quality line. If you
report problems, the local telephone company probably will not be
concerned about poor data transmission.
