10.3 Step 2 : SHDSL test and set up adjustment
• Connect the two XSRING+ to the lines.
• Switch the power ON.
• The connection on each line will be established 30 s latter.
• The led attached to each SHDSL port reports the connection status according to the table below :
STU-C STU-R
The other XSRING+ has not been detected
(for instance when the line is not connected)
Flashing 0,1 s ON / 2 s OFF Flashing 1 s ON / 1 s OFF
The other XSRING+ has been detected Flashing 1s ON / 1s OFF Flashing 1s ON / 1s OFF
Data rate negotiation Flashing 0,3s ON / 0,3s OFF Flashing 0,3s ON / 0,3s OFF
Connected Always ON Always ON
Connected & transmitting data Flashing at high speed Flashing at high speed
• Connect the PC to the SHDSL switch configured as an STU-C.
• Click Diagnostic> Network status> Interface, to check the connection quality on each line.
The “SHDSL ports state” table is displayed. It reports the status of each SHDSL port.
• 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 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 connection run correctly, send periodically a PING to a remote device to
check that no error occur and that the response delay is as expected.
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;
