3 Product overview
3.1 Function
The XSRING+ provides two SHDSL interfaces to extend Ethernet over a twisted pair.
The XSRING+ can be used in the following cases :
Daisy chain network
or
Daisy chain network using the
By-pass function (XSRING+BP
only)
Point to point transmission over
one or two twisted pairs to multiply
the data rate and provide a backup
link
Failsafe ring network using the
proprietary algorithm based on STP
Complex redundant topologies
using the RSTP algorithm
OVERVIEW
Page 10 User’s guide ref 9018809-01 XSRING+ SHDSL switch
3.2 Redundancy solutions: RSTP and proprietary failsafe ring
Industrial applications need reliable networks; one way to provide reliability is to provide backup paths
which form loops in the Ethernet network.
However, loops are highly unwelcome in Ethernet networks, as they can cause broadcast storms,
eating up all the available bandwidth and causing network outage.
The goal of redundancy protocols is to make Ethernet work of networks containing loops and to
provide a path at each time, even, if possible, when one or several links are in failure.
The XSRING provides two solution to handle redundancy :
RSTP
RSTP, standing for "Rapid Spanning Tree Protocol" is specified by the IEEE in the 802.1D-2004
document.
RSTP can handle complex structures ; RSTP can be used with devices from other manufacturers.
The failure detection delay and the recovery delay in an shdsl network is around 10 seconds.
Proprietary failsafe ring algorithm
Based on the STP algorithm, that solution makes possible to handle a ring structure up to 16 SHSDL
switches.
The advantages of that solution is that the failure detection delay and the recovery delay is only a few
seconds (One second if the ring counts 5 SHDSL switches); moreover, it is very simple to configure.
OVERVIEW
XSRING+ SHDSL switch User’s guide ref 9018809-01 Page 11
3.3 The by-pass function
When the network is a daisy chain – that case is very frequent in industrial applications - and when,
however, it is not possible to build a failsafe structure like a ring, the XSRING+BP offers a very useful
function called the “By-pass function”.
The XSRING+BP includes an electro-mechanical relay between both lines; that relay is automatically
closed to connect the two lines when the XSRING is switched off.
For instance, if the XSRING #2 cabinet is switched off for maintenance, for instance, the by-pass relay
inside the XSRING #2 will automatically connect the line coming from the XSRING #1 to the line going
to the XSRING #3.
After a few seconds, the XSRING #1 detects the connection default and establishes immediately the
connection with the XSRING #3.
In that way, the connection is recovered after a short delay between the XSRING+ #1 and the
XSRING+ #3.
3.4 Data rate versus distance
Each interface features an adaptive data rate from 128 Kb/s up to 5,7 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.
The table in appendix 1 gives the data rate which can be expected over a line versus the length of the
line.
3.5 Ethernet ports
The XSRING provides 2 or 4 Ethernet RJ45 interfaces (depending on the product reference).
OVERVIEW
Page 12 User’s guide ref 9018809-01 XSRING+ SHDSL switch
3.6 VLANs
The XSRING features VLAN per port :
Each Ethernet port can be assigned to a particular VLAN. A device connected to an Ethernet port
belonging to a particular VLAN can communicate only with devices connected to Ethernet ports
belonging to the same one.
3.7 Quality of service
The product provides “DiffServ” quality of service functionality to give transmission priority to critical
applications.
Devices TCP ports and IP addresses are classified in 4 priority classes.
A minimum and a maximum bandwidth is allocated to each class.
3.8 SNMP
3.9 Serial gateway
The XSRING –1220, -1230, -2220 or –2230 feature a 2 ports serial gateway.
The gateway features raw TCP client and server, raw UDP, modbus client and server, telnet and
multicast.
3.10 Diagnostic functions
The XSRING html server provides diagnostic pages giving the guarantee the transmission quality is
what it has to be.
3.11 Html configuration
The XSRING can be configured either with an html browser if advanced functions are necessary
(QoS, RS gateway, diagnostic …).
It can be configured with a few DIP switches for simple unmanaged applications.

4 DIN rail mounting
Mounting the unit on the DIN rail
This unit should be mounted on 35 mm DIN-
rail, horizontally mounted.
Removing the unit from the DIN rail
5 Cooling
To avoid obstructing the airflow around the unit, the spacing must be at least 25 mm above and below, and 10 mm left and
right.

Power consumption : 6 W
The product is protected against the inversion of the polarity of the supply voltage.
7 Isolation and grounding
The enclosure of the product is metallic; It must be grounded.
The minus polarity of the supply voltage is common with the minus voltage of the electronic board –
usually called 0 V - and is isolated from the enclosure.
Moreover, the Ethernet signal and the SHDSL signal are isolated through transformers. It is why
• the versions XSRING+2400 and XSRING+BP2400 are fully isolated. The common mode voltage must not exceed 1500 V.
• The versions XSRING+2220 and XSRING+BP2220 provide the minus voltage through the RS232 interface and through
the RS485 interface.
• The versions XSRING+2230 and XSRING+BP2230 provide the minus voltage through the RS232 interface.

distance, inside the same cabinet for instance, and at low data rate up to 19200 b/s.
If the RS485 line has to be longer, one of the devices connected to the RS485 line must provide
standard polarisation resistors, and a 150 Ohm termination resistor must be connected at each end of
the line.

11 Line cable
Twisted pair
The XSRING+ shdsl switch is designed to be connected to one or several telephone grade twisted
pairs.
The conductor diameter must be included between 0.4 mm and 1 mm.
Shielded cable
It is better to use a shielded cable.
The shield must be connected to the earth at one of its ends.
The shield decreases the influence of the electromagnetic ambient noise on the shdsl signal.
Moreover, the shield protects the XSRING+ shdsl switch against lightning.
Electrical power cable
Two power conductors can be used instead of a twisted pair to set an shdsl connection.
However, because the two wires are not twisted, the ambient electrical noise may disturb the
transmission.
Compared to the transmission over a twisted pair, the maximum distance between two SHDSL
switches is decreased.
Cross talk
If the cable is made of several pairs, each pair can be used to transmit a particular shdsl connection ;
however the shdsl signal transmitted in one pair may disturb the shdsl signal transmitted in another
one, and, in some cases, may decrease the effective data rate of both shdsl connections.
