• Check the quality of each SHDSL port :

The SNR ratio margin must be 2 / 4 or 3 / 4 or 4 / 4.

The number of erroneous seconds during the last hour must be next to 0.

The number of link losses during the last 24 hours must be 0 or a few ones.

• If the SNR ratio margin of one shdsl port is only 1 / 4, go back to “Ethernet & switching” , select a

more reliable connection profile (Endurance instead of standard for instance) for that port and

check the connection again.

• Once all the SHDSL connections run correctly, send periodically a PING to a remote device to

check that no error occur.

Remark : one can use the PING tool included in the product (Diagnostic > Tool > PING).

• If, in spite of these modifications, the result of one connection remains insufficient,

check each conductor of the line is correctly connected;

disconnect and by-pass the surge arresters to check if they are not the cause of the dysfunction;

check the cable shield is correctly connected to the ground.
