Hi All,

Is this Common DSL Faults below the same with yours?

If not, could you let us know the differences? Then we can improve the document. 

Many Thanks!

 

 Fault  Fault Identification  Fault Resolution
The line is old or is not properly connected to the main distribution frame (MDF).
  • Check whether insulation has worn away and the line is exposed.
  • Check whether the line connector is rusted or the line is not properly connected to the MDF.
  • Check whether a cyclic redundancy check (CRC) packet loss occurs on the line.
Replace the line or reconnect it to the MDF.
The line is connected incorrectly to the associated devices. If a user has a splitter to split voice and data services, common line connection faults are:
  • The phone and the modem are not connected to the output ports on the splitter. Instead, they are connected directly to the drop-in twisted pair.
  • The phone or the modem is connected to the input port on the splitter.
Reconnect the line as follows:
  • Connect the drop-in twisted pair to the input port on the splitter.
  • Connect the phone and the modem to the output ports on the splitter.
 Subscriber lines form a loop.  Check whether two asymmetric digital subscriber line (ADSL) lines are connected directly to each other.  Reconnect the subscriber lines to disconnect the loop.
 An interference source exists around the subscriber lines.  Check whether a strong interference source, such as a wireless base station or a high-frequency switch power system, exists around the subscriber lines.  Remove the interference source or re-route the subscriber lines.
