Check the quality of each SHDSL port.
The SNR ratio margin must be at least 2/4.
The number of erroneous seconds during the last hour must be close to 0.
The number of link losses during the last 24 hours must be 0 or a few ones.
•
If the SNR ratio margin is only 1/4d e 1/4, with the STU-C standard profile, assign the STU-C Endurance
profile and check again the connection.
•
Once all the SHDSL connection run correctly, send periodically a PING from a PC to a remote XS or device
to check that no error occurs.
Remark : one can use the PING tool included in the XS (
Diagnostics > Tools > PING ).
•
If, despite these changes, the quality is insufficient, or if disconnections occur, or if the connection is not
established, check the line :
Check that each conductor of the line is correctly connected.
Disconnect and by-pass the surge protectors to check if they are the cause of the dysfunction.
Check that the cable shield if any, is correctly connected to the ground.
