Abstract
A modem structure for connection to a line carrying both DSL signals and CTS signals, and a method of operation thereof, are provided. The modem structure includes a DSL modem connectable through a filter to remove the CTS frequencies on said line, and connected to network port. A diagnostic device is connected to the DSL modem to diagnose problems stored with the DSL modem. An analog modem is also provided that is connectable to said wire through a filter that filters out DSL signals on the line, and selectively connectable to said diagnostic device to read information in the diagnostic device and transmit the readings, In operation, the network port is continuously connected to DSL signals to operate network devices at high frequency, and said diagnostic device is selectively connected to the CTS device for diagnostic purposes using low frequency signals.
