13 Connecting the shdsl switch to the line
The SHDSL signal is not polarised ; it is why the two conductors of one line can be inverted.
13.1 Point to point connection using two twisted pairs
The XSRING+2XXX provides two SHDSL interfaces.
Two twisted pairs can be used to set a connection between two SHDSL switches. In that case, the
effective data rate will be the double compared to a connection using only one pair.
We recommend to wire the first line from port 1 of the first XSRING+ to the port 1 of the second
XSRING+ as shown below in order to make the configuration and the diagnostic easier.
13.2 Multidrop or ring connection
If the SHDSL switches are connected to shape a multidrop network or a ring network, we recommend
to connect the lines as shown below .
In that way, the configuration of each SHDSL switch will be similar.
