Poor Transmission Quality on Modem
Possible Cause: A high-speed modem is connected, through an extension jack on a
system module, to a standard central office telephone line; but the line quality is not
sufficient to generate a clear signal when the modem transmits through the system
interface.
What to do: Either connect the modem directly to the network interface jack for a line, or
contact your local telephone company for information about upgrading line quality.
