“Data rate” parameter
If the value “auto” is selected, the data rate will be negotiated by the LTU
itself; the connection delay is much longer, because the XSLAN as to try
all the data rates and select the best one.
If a value from 128 Kb/s to 2.3 Mb/s is selected, the XSLAN will try to
connect at that data rate.
To select the right data rate,
?? refer to appendix 1 to estimate the data rate which is possible to get
according to the distance.
?? Select that data rate and save.
?? Reboot the product.
?? Test the connexion quality.
The lower led of the RJ45 SHDSL connector blinks and is then lighted.
The “Diagnostic” and then “networks status” page displays the
connection process and gives an index (1 to 5) of the transmission
quality; the transmission quality has to be better than 3; otherwise,
decrease the data rate.
?? Press the “Show statistics button to check the transmission is error
free and the signal to noise ratio is OK
“Signal power” parameter
The power of the signal emitted towards the line is normally 14.5 dBm.
It must not be reduced except for very short distance transmission and if
errors appear.
“SHDSL port aggregation” parameter (XSLAN-2400 –2220 –2230)
If 2 pairs are used (each connected to an SHDSL port), and if the
aggregation option is selected, the data rate will be twice what it would be
with only 1 pair (2 wires).
Moreover, in case of a break of 1 line, the other line will backup the
transmission.
