DIP SWITCHES SET UP
Remark :
It is advised to select the AUTO mode only for test purposes, because
the connection delay can be long.
2.3 SHDSL network topology DIP switches (SW6, SW7)
• Point to point or daisy
chain
Set the SW6 and SW7 OFF.
• Failsafe ring
The ring topology provides a much better availability, in particular when
the network includes a great number of SHDSL switches :
if one line fails, the communication remains possible as previously
between all the devices.
If one SHDSL switch fails, the communication remains possible
except with the devices connected to the SHDSL switch in failure.
Ring master :
Set SW6 ON and SW7 OFF
Other SHDSL switches :
Set SW6 OFF and SW7 ON
• Two twisted pairs operation
The data rate will be twice what it
would be with only 1 pair (2 wires).
Moreover, in case of a failure of 1 line,
the other line will backup the
transmission.
Set SW6 ON and SW7 ON.
