OVERVIEW 3 3.1 Product overview Function The XSRING+ provides two SHDSL interfaces to extend Ethernet over a twisted pair.
OVERVIEW 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.
OVERVIEW 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.
OVERVIEW 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.

INSTALLATION 4 DIN rail mounting Mounting the unit on the DIN rail This unit should be mounted on 35 mm DINrail, 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.
INSTALLATION 8 RS232 interface The RS232 data rate can be tuned from 1200 to 115200 b/s with parity (even / odd) or no parity. The data terminal must be less than 10 meters far from the modem.
INSTALLATION 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.
INSTALLATION 12 Protecting the shdsl switch from lightning if the line is exposed to lightning, we advise to use an surge arrester at each end of the line and to connect the shield of the cable to the earth. Line cable shield : If the line is shielded, the shield must be connected to the earth; only at one end if it is not interrupted along the line.
INSTALLATION 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.
INSTALLATION 13.3 By-pass function To enable the by-pass function, connect the line1 to the “1 by-pass” screw block and the line 2 to the “2 by-pass” screw block as shown below. . 14 Input and output Input That input is not isolated. if it is opened, an SNMP trap will be sent to the SNMP server is that function has been enabled. Alarm output 1 relay output is provided to indicate an alarm. The alarm condition can be selected using the html server.
SET UP 1 Set up steps To configure the XSRING, we advise to proceed as follows : • Connect a PC to the router • Set up the LAN interface • Set up static routes • Set up the SHDSL connections • Set up the RSTP or failsafe ring redundancy protocol • Set up VLAN • Set up QoS • Set up SNMP • Set up the serial gateway XSRING+ SHDSL switch User’s guide ref 9018809-01 Page 25
SET UP 2 2.1 Connecting a PC to the XSRING+ for configuration Overview Administration server address : The administration html server is located at the LAN IP address of the SHDSL switch (The factory IP address is192.168.0.128). First set up : For the first configuration, we advise to connect the PC directly to the LAN interface of the SHDSL switch.. Further set up modifications : Modifications can be carried out from the LAN interface, or remotely.
SET UP 2.3 Modifying the configuration from the LAN Launch the html browser and enter the IP address assigned to the router. Or, launch the ETICFINDER utility to detect the XSRING IP address. Remark : If the home page cannot be displayed, refer below. 3 • Rebooting the XSRING+ after parameters changes After completing a page, click the « Save » button at the bottom of the page. • After some parameters changes, the XSRING+ must restart.
SET UP 6 Recovering a free access to the administration server Press the push-button, located on the top of the product, is pressed, the default configuration is temporarily restored. The IP address of the html server is 192.168.0.128. and accessing to it is free. Make the necessary modifications and save. 7 Assigning an IP address to the LAN interface An IP address must be assigned to that interface; the HTML server is located at that IP address.
SET UP To enable the router function and assign an IP @ to the SHDSL interface of the XSRING+, • select “Set up > IP protocol & routing > IP protocol”; • select the “Router mode” checkbox; • enter the IP address and netmask assigned to both SHDSL interfaces. To register a route, • select “IP protocol & routing > Static route ”; • click the ”Add” button; • Enter the parameters of the route. To enable the RIP protocol instead of programming routes, • select “IP protocol and routing > RIP”.
SET UP 9 SHDSL connection set up overview 9.1 Principle of operations The SHDSL switch called STU-C is in charge of setting the connection When two shdsl switches are connected through a twisted pair, one has the function to initiate the connection, to analyse the connection quality, and to negotiate the data rate; the other SHDSL switch can only accept. The SHDSL switch which initiates the connection is called the STU-C, while the one which accepts the connection is called the STU-R switch.
SET UP 9.2 SHDSL connection profiles Auto STU-R profile : That connection profile has to be assigned to an shdsl port when it has to wait for the connection (see the drawing above). Endurance STU-C profile : An shdsl port to which that profile is assigned will initiate the connection. The value of the SNR margin of that profile is maximum; it means that the connection will be set at a low data rate to decrease the disconnection probability.
SET UP 10 Setting up a multidrop or ring SHDSL connection This chapter describes how to set up two XSRING+2XXX when hey are used in a multidrop (or daisy chain) network. 10.1 Set up steps Step 1 : SHDSL Connection set up To assign the STU-R and STU-C profiles to the SHDSL ports Step 2 : Connection test and set up adjustment. 10.
SET UP 10.3 Step 2 : SHDSL test and set up adjustment • Connect the two XSRING+ to the lines. • Switch the power ON. • The connection on each line will be established 30 s latter.
SET UP 11 Setting up a point to point connection using 2 twisted pairs This chapter describes how to set up a connection between two XSRING+ using up to four twisted pairs to multiply the effective data rate. The XSRING+2XXX SHDSL switch provides two SHDSL interfaces; using two twisted pairs, the data rate can reach 11,4 Mb/s (5.7 Mb/s over each pair) and even 20 Mb/s (10 Mb/s over each pair) over 1 Km. 11.

SET UP Setting up the XSRING+ number 2 • Click Set up > Ethernet & switching > SHDSL ports. • Select « Enable » (port 1 or 2 or 3 or 4). • • • Assign one connection profile to the SHDSL port (Standard or Performance or Endurance or TurboShort). Select the line aggregation options Remark : the aggregation option must be the same for the XSRING+ number 1 and the for the XSRING+ number 2. SHDSL page XSRING+ 11.
SET UP • Check the quality of each SHDSL port : The SNR ratio margin must be 2 / 4 or 3 / 4 or 4 / 4. The number of erroneous seconds during the last hour must be next to 0. The number of link losses during the last 24 hours must be 0 or a few ones. • If the SNR ratio margin of one shdsl port is only 1 / 4, go back to “Ethernet & switching” , select a more reliable connection profile (Endurance instead of standard for instance) for that port and check the connection again.
SET UP 12 RSTP redundancy protocol • Select “Set-up > Ethernet & switching > RSTP”. • Select the RTSP mode. The page is divided in two parts : The general parameters. The Ethernet & SHDSL ports parameters. General parameters “Bridge priority” parameter : This value is prepended to the MAC address of the bridge to form the bridge ID. This is used by the network to choose which bridge will become the root of the spanning tree. The root is the bridge with the lowest bridge ID.
SET UP “Edge port” parameter : An Edge port is a port located on the border of the network, with no bridge attached to it like, for instance, an industrial device or a PC. BPDU are not transmitted to that kind of port; moreover, that kind of port cannot be blocked. “P2P” parameter : Select that check box if the port is participating in a direct link between 2 RSTP enabled switches (no unmanaged switch must be inserted on that link).
SET UP 14 VLAN 14.1 Overview VLAN function The VLAN technology conform to the IEEE 802.1Q norm makes possible to transmit up to 4096 Ethernet networks over the same physical Ethernet layer. The devices belonging to the same Ethernet VLAN can exchange Ethernet frames with one another but cannot exchange frames with devices belonging to another VLAN except if a level 3 switch or an equivalent device makes possible to bridge that VLANs.
SET UP 14.2 Set up Attention : Before saving the VLAN configuration, make sure you will be able to access to the administration html server through an Ethernet port or remotely through the line. One Ethernet port at least belong to the same VLAN as the administration html server of the XSRING+. • Select “Set up > Ethernet & switching > VLAN”. The VLAN page is displayed. • Select the “Enable VLANs” checkbox. That page is divided in three parts : Egress policy, Ingress policy.
SET UP 14.2.1 Egress policy set up That part of the page is made to register the VLAN IDs and to specify which process must be applied to exiting tagged frames with that VLAN ID. The processes which can be applied to an outgoing frame are : Frames exit that port untagged. Frames exit that port tagged. Frames exit that port unmodified Port does not belong to that VLAN Example Three VLANs are defined : 4, 5, 12. The Ethernet port 1 is registered on VLAN 4 and 5.
SET UP To set up the Egress policy • Select “Set up > Ethernet & switching > VLAN”. • Click the « Add » button located under the Egress policy table. • Enter a VLAN ID and assign a name to that VLAN. For each Ethernet port (including the SHDSL ports), select which Egress policy must be applied. Frames exit tagged : Ethernet frames tagged with that VLAN can exit that port. The frames exit tagged. Frames exit untagged : Ethernet frames tagged with that VLAN can exit that port. The frames exit untagged.
SET UP 14.2.2 Ingress policy set up That part of the page is made to register which process must be applied to the Ethernet frames when they enter a given port of the switch or when they are received from the line. One defines which already tagged frames can enter the switch; which VLAN ID will be assigned to untagged frames coming into the switch.
SET UP To set up the Ingress policy • Select “Set up > Ethernet & switching > VLAN”. • Go to the Ingress policy part of the page • For each Ethernet port and for the SHDSL ports, select the Ingress policy and the VLAN ID which must be applied to the untagged frames entering the XSRING+ switch. “LAN (1 to 4) Ingress policy” parameter : Accept all frames : All incoming frames are accepted on this port, regardless of the VLAN they belong to. If a tagged frame enters the switch, it is not modified.
SET UP 14.3 Html server and serial gateway When VLAN management is enabled, the administration web server and the serial gateway must belong to a VLAN. “Administration VLAN ID” parameter : Enter the VLAN ID to which the administration html server belongs. “Serial gateway VLAN ID” parameter : Enter the VLAN ID to which the serial gateways belong. Remark : If the serial gateway does not belong to the same VLAN as the html administration server, a particular IP address must be assigned to serial gateways.
SET UP 15 SNMP 15.
SET UP 15.3 Setting up the SNMP traps To enable the SNMP traps, • Select “Set up > Alarms > SNMP traps”. • Select the traps which must be transmitted by the XSRING+ “Product start up – cold start” checkbox: If that checkbox is selected, a trap is transmitted each time the XSRING+ restarts. “SHDSL link 1 (or 2 ) connection” checkbox: If that checkbox is selected, a trap is transmitted each time the shdsl interface 1 (or 2 ) connects.
SET UP 16 Quality of service (QoS) 16.1 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. For instance, it can be difficult to transmit on the same SHDSL network an important video data flow, a small but critical PLC protocol data flow and digital voice protocols. To solve that question, the XSRING+ implements the DiffServ algorithm.
SET UP An example is given hereafter : Minimum bandwidth % of the whole bandwidth Maximum bandwidth % of the whole bandwidth 20 % 30 % 10 % 60 % unlimited 30 % 20 % 40 % 90 % CLASSES : Platinum Gold Silver Bronze Total Assigning each traffic to the classes Each traffic (Service plus device) entering the shdsl network can be assigned to one class; Any traffic not assigned to one class is supposed to belong to the default class.
SET UP Step 3 : Define the classes • Select the QoS menu. Assign a minimum and a maximum bandwidth to each class. Step 4 : Classify the traffics • Under the traffic classification table, click the “Add” button. • Assign each device and service you wish to a class (Gold, silver etc…).
SET UP 17 Serial gateway The XSRING+2220 or BP2220 feature 1 RS232 and 1 RS485 – 2 wires – ports. The XSRING+2230 or BP2230 feature two RS232 serial ports. A serial gateway can be assigned to each serial port . However, if the same type of gateway is assigned to both serial ports, the UDP or TCP port numbers must be different. For instance, it is not possible to use modbus TCP with the port 502 at the same time on the serial ports 1 and 2.
SET UP 17.1 Modbus gateway The ETIC modbus gateway is made to link modbus devices connected to its serial interface to TCP modbus devices connected to the ethernet TCP/IP network. A TCP Modbus client device is a device connected to the ethernet TCP/IP network and able to send a modbus request to a modbus TCP server which is in charge of answering; A TCP modbus client is equivalent to a master.
SET UP “Activate Proxi cache” parameter : Enable the proxi option if you wish to avoid to frequent requests on the serial interface. “Cache refreshment period” parameter : the same request is received twice or more inside that delay, it will be sent only once to the slave on the serial interface. “Timeout waiting for the answer” parameter : Set up the timeout the gateway has to wait for the answer of the modbus slave.
SET UP 17.1.2 “Modbus client” gateway That gateway can be used only if a serial modbus master device is connected to the serial interface of the XSRING+. That modbus master can send requests to slaves connected to the serial interface or to up to 256 modbus TCP servers connected to the IP network (i.e. modbus slaves).
SET UP 17.2 RAW TCP gateway 17.2.1 Raw client gateway The RAW client gateway can be used if a serial “master” device has to send requests to one slave device (also called server) located on the IP network. The server can be either an ETIC gateway or a PC including a software TCP server. • Select the “transparent” and then the “raw client COM1” or the “raw client COM2” menu .
SET UP 17.2.2 Raw server gateway That gateway can be used if a serial slave device has to answer requests coming from devices located on the IP network and acting like a master (also called TCP client). • Select the “transparent” and then the “raw server COM1” or the “raw server COM2” menu.
SET UP 17.3 RAW UDP gateway 17.3.1 Overview The RAW UDP gateway enables you to connect together a group of serial or IP devices through an IP network. The group can include IP devices if they have the software pieces able to receive or transmit serial data inside UDP. Serial data transmitted by each device is transmitted to all other serial devices through the IP network. A table of IP destination gateways is stored in each XSRING+ belonging to the group.
SET UP 17.4 Multicast gateway Internet Protocol multicast is a bandwidth-conserving technology that reduces traffic by simultaneously delivering a single stream of information to thousands of corporate recipients. Thus, the multicast gateway must be used when • a serial master device has to send requests to multiple slave devices; that devices can be IP or serial devices. • Or when an IP master device (client) has to send requests to multiple slave devices; that devices can be IP or serial devices.
SET UP • 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. “Timeout of RS232/485 end of frame” parameter Set up the delay the gateway will wait before declaring complete a string received from the asynchronous device.
