2.1
Product overview
Function
The XSLAN shdsl switch enables to extend an Ethernet network over
kilometres using one or two simple voice-grade twisted pairs
(telephone lines).
Point to point
1 pair (up to 2.3 Mb/s)
2 pairs (up to 4.6 Mb/s)
2.2
Shdsl operations
The XSLAN comes with 1 or 2 SHDSL interfaces which allow to extend
an ethernet network at up to 2.3 Mb/s with 1 pair or 4.6 Mb/s with 2 pairs.
2.2.1 Data rate
Each SHDSL interface features an adaptive data rate from 128 Kb/s up to
2.3 Mb/s.
The data rate is a function of the cable quality and the distance with the
next SHDSL switch. For instance, the maximum distance between 2
switches through a line is 13 Km (8 miles) with a 0.9 mm wire diameter
cable.
2.2.2 Distance between switches
The table in appendix 1 gives the data rate which can be expected over a
line versus the length of the line (distance between 2 switches).

The XSLAN provides 2 or 4 ethernet RJ45 interfaces (depending on the
product reference).
2.4
Quality of service
The product (except XSLAN-140) provides “DiffServ” quality of service
functionality to give transmission priority to critical applications.
Devices TCP ports and IP addresses are classified in 5 priority classes.
A minimum and a maximum bandwidth is allocated to each class.
2.5
Asynchronous gateway
The XSLAN (-1220, -1230, - 2220 or 2230) include a versatile 2 ports
asynchronous gateway.
It offers raw client and server, modbus client and server, telnet and
multicast protocols.

CONFIGURATION
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
XSLAN shdsl switch
User’s guide ref 9014709-01
Page 21
Configuration
1.2
Inverse-multiplexing
??Point to point
Set the SW6 and SW7
OFF.
??Inverse-multiplexing
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.
Set SW6 ON and SW7 ON
2
Connecting a PC to the XSLAN for configuration
If the product is coming from factory, we advise to configure the XSLAN by
connecting directly the PC to one of the RJ45 ports (see paragraph 3.1).
2.1
Configuring with a PC connected to the XSLAN Ethernet interface
Step 1 : Check the DIP switches SW1 and SW2; they must be set to OFF
and OFF to select the stored IP address, or, if necessary, to ON and OFF
to restore the factory IP address.
Coming from factory, the DIP switches SW1 and SW2 are set OFF (ready
for configuration); and the IP address of the XSLAN is 192.168.0.128.
Step 2 : Create or modify the PC TCP/IP connection
Assign to the PC an IP @ in accordance with the XSLAN IP address.
For the first configuration, assign or instance 192.168.0.127 to the PC.
Step 3 : Connect the PC directly
to an XSLAN ethernet interface
using any Ethernet cable (straight or
crosswired)

crosswired)
Step 4 : Launch the navigator
Enter the IP @ of the XSLAN.
The Home page of the
administration server is displayed
Note :
If the home page cannot be displayed, refer to paragraph 4 below.
XSLAN shdsl switch
User’s guide ref 9014709-01
Page 23
Configuration
2.2
Configuration through the LAN
Case of a LAN with a BOOTP or DHCP server
Step 1 : Set the DIP switches SW1 OFF and SW2 OFF to select DHCP /
BOOTP operation.
Step 2 : Launch ETIC FINDER to detect the XSLAN over the LAN.
Click the product once detected.
The Home page of the administration server is displayed.
Note :
If the home page cannot be displayed, refer to paragraph 4 below.
Case of a LAN without BOOTP or DHCP server
That method must be avoided for the first configuration, because the
factory IP address of the XSLAN can also have been assigned to another
product.
Otherwise, launch the html browser and enter the IP address assigned to
the XSLAN.
Or, launch the ETICFINDER utility.
3
Wrong IP address or password
When launching the html browser, the homepage of the html server may
not be displayed; the cause may be the IP address you enter or the
password you use are wrong.
if the XSLAN IP address you enter is wrong, you can recover the
factory IP address by setting SW01 ON and SW2 OFF.
The factory IP address 192.168.0.128 will be restored as long as the
SW01 micro-switch will be left ON. Once, SW01 will be set OFF, the
stored IP address (the IP address which is displayed) will be used by the
product.

User’s guide ref 9014709-01

Configuration
Wrong Login to the administration server
The access to the administration server can be protected by a login and
password; If the Login & or password entered to access to the
administration server have been rejected, it is possible to recover a free
access, by setting SW01 ON and SW2 OFF.
Careful : The factory IP address 192.168.0.128 will also automatically be
assigned to the product as long as SW01 will remain ON and SW2 OFF.

4.4.1 SHDSL port
Mode parameter
When 2 XSLAN switches are
connected to one another through a
line, one has to be configured as an
LTU (master party) and the other as
an “NTU”. (slave party).
The switch which is named “LTU”
negotiates and forces the data rate
over the line; the NTU can only
accept.

“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.

Routing (except XSLAN-140)
It can be useful to enable the routing functions to avoid unnecessary traffic
over the shdsl link when the traffic is heavy on each Ethernet network.
In that case, an IP address has to be assigned to the SHDSL interface
(see below) and routes have to be entered (see below shdsl network and
also RIP and static routes).
SHDSL network (except XSLAN-140)
An IP address has to be assigned to the shdsl interface only it the router
function of the XSLAN has been enabled.

Quality of service (QoS) menu (except XSLAN-140)
4.6.1 DiffServ benefits & overview
The goal of Quality of Service algorithms is to guarantee that critical data
flows will be transmitted with lower delay than others.
The XSLAN implements the DiffServ algorithm.
We call “traffic” an IP address and a port Nr.
Four traffic classes are featured :
Premium, Gold, Silver, Bronze, Default (or Best effort).
A minimum and a maximum bandwidth have to be assigned to each class
except to the Premium class, the bandwidth of which is not limited.
This operation is carried-out with the “classes” menu.
Each traffic (i.e. a port Nr and IP address) entering the shdsl network has
to be assigned to one class; All traffics not assigned to any of the classes
are supposed to belong to the default class.
This operation is carried-out with the “classification menu”.
Thus, when a traffic enters the XSLAN switch, it is analysed by the switch
and marked as premium or gold or silver or bronze or default and then
transported through the shdsl network with the relevant priority.
4.6.2 “Classes” menu
Set a minimum and a maximum bandwidth to each class.

Configuration
The Internet Assigned Numbers Authority (IANA) controls the assignment
of IP multicast addresses.
The range of addresses from 224.0.1.0 through 238.255.255.255 are
called “globally scoped addresses”. They can be used to multicast data
between organizations and across the Internet.
The range of addresses from 239.0.0.0 through 239.255.255.255 contains
limited scope addresses or administratively scoped addresses. These are
defined by RFC 2365 to be constrained to a local group or organization.
Routers are typically configured with filters to prevent multicast traffic in
this address range from flowing outside an autonomous system (AS) or
any user-defined domain. Within an autonomous system or domain, the
limited scope address range can be further subdivided so those local
multicast boundaries can be defined. This also allows for address reuse
among these smaller domains.
Note This address range is only for the group address or destination
address of IP multicast traffic. The source address for multicast
datagrams is always the unicast source address.
To configure the multicast gateway,
?? Select the “transparent” and then the “multicast” menus.
?? Enable the multicast gateway and set up the parameters as follows :
“RS232/485 input buffer size” parameter
Set up the maximum length of an asynchronous string the gateway will
store before transmitting it to the IP network.

Set up the delay the gateway will wait before declaring complete a string
received from the asynchronous device.
Once declared complete, the gateway will transmit the string to the IP

An LTU interface must be
connected to an NTU interface.
Data rate = Select the auto option or a data rate in accordance with the
distance (see appendix 1).
Note : If the “auto” option is selected, it will cause the XSLAN to try all the
data rates. The connection delay will be longer. Moreover, the XSLAN
software will select a cautious solution. It is why the “auto” option will be
selected only if the distance is short (less than, 1 Km).
Don’t forget to SAVE each page and to REBOOT when the configuration
is carried out (click the red button “Reboot”).
