XSLAN shdsl switch User’s guide ref 9014709-01 Page 21
1 Overview
The XSLAN can be configured either with DIP switches or with an html
browser through Ethernet.
The Html offers very useful diagnostic functions like Error rate statistics,
ping, logs and so on. It is advised to use the html server when the network
is complicated or when distances between switches are long.
Moreover, advanced functions like Quality of Service or the asynchronous
gateway can only be configured with the html server. To select DIP
switches configuration, set SW1 et SW2 ON.
1.1 SHDSL interfaces configuration (SW3, SW4, SW5)
When 2 XSLAN switches are
connected to one another through a
line, one has to be configured as an
LTU (calling party) and the other
one as an “NTU”. (called party).
The switch which is named “LTU”
negotiates and forces the data rate
over the line; the NTU can only
accept.
The data rate can be either
negotiated by the LTU itself (auto
mode) , or imposed by the user with
the DIP switches.
Inverse-multiplexing case
If port 1 has been configured as an
NTU (SW3=OFF, SW4=OFF,
SW5=OFF), port 2 is forced as an
NTU
