Echo LANlink Router Option User Manual 1 INTRODUCTION This user manual describes installation, configuration and operation of the Echo LANlink Multiplexer Router option, and must be referred to in conjunction with the Echo LANlink Multiplexer User Manual. The Echo LANlink is an E1 time division multiplexer (TDM) operating at 2Mbps compliant with both EUROPEAN and UK G.703 communications standards.
The Router Option card is easily configured using the management terminal connected to the Echo LANlink from either end of the link, or through Telnet at a relevant workstation either LAN. 1.1 Functional Overview The Router Option card supports both transceiver connection (AUI port) and hub (10BASE-T port) connection to a 10MHz Ethernet LAN. Ethernet frames are transported to/from the remote LAN using some or all of the main communications link bandwidth.
the Branch Office could access the Headquarters General Server via the Echo LANlink, but accesses to the Finance Server could be stopped using subnet masking in the Echo LANlink. Figure 2 Restrictive Firewall Example In addition to the features of the router, all the existing functions of the Echo LANlink are still available.
2 USE AND CONFIGURATION This section covers connection and set-up of the Echo LANlink Router Option, and must be used in conjunction with the Echo LANlink User Manual.

2.6.9 ROUTER WAN LINK STATUS The status of the link between the two routers is displayed. Echo LANlink Router Option User Manual Issue 1.
3 INSTALLATION WARNING – Refer to Appendix A for Safety Instructions. WARNING - The multiplexer must be disconnected from the power supply and all peripheral connections before opening. 3.1 Opening the Multiplexer With the power cord and all peripherals DISCONNECTED, the screws on the left, right and top of the multiplexer are removed using a Pozidrive screwdriver to gain access to the interior of the multiplexer.
3.2 Internal Link LK13 Locate the internal connector LK13 on the motherboard (refer to Figure 9). This will be fitted with shorting links if the Echo LANlink was supplied without the Router Option. Remove the shorting links before fitting the Router Option. The links may be repositioned on one pin for storage. 3.3 Installing the Router Option Remove the option blanking plate above the CH 1 and CH2 connectors on the rear panel of the multiplexer. The blanking plate may be discarded if not required.
3.4 Testing Replace the cover and screws before powering up the unit. Correct installation of the Router Option may be confirmed by the login prompt (see section 2.3) appearing on the terminal screen. If the red error LED on the front panel is on, this indicates hardware fault has occurred. In this case, disconnect the power cable and check the installation of the Router Option is correct. 3.
3.7 Quick Configuration The first stage in configuration is to allocate some bandwidth of the communication link to the router. The second stage is to configure the SERVICE SETUP to allow communication between the two routers. 3.7.1 Multiplexer Configuration From the main menu enter MULTIPLEXER MANAGEMENT. Allocate bandwidth to the router by entering ‘R’ in any free timeslot positions near the bottom of the screen. Each timeslot allocated will contribute 64Kbps of bandwidth to the router.
3.7.2.4 Receive IP RIP To enable routes to destinations within the local network to be added to the routing table this field should be set to the appropriate protocol; NONE, RIP1, RIP2 or both RIP1 and RIP2. If the RIP version is unknown then set BOTH. 3.7.2.5 Transmit IP RIP To allow the Router to propagate routes learnt from the WAN to the local network, this field must be set to the correct value for the RIP protocol being used or to NONE to disable RIP transmission.
3.7.2.11 Receive IPX RIP Set this field to YES to receive IPX RIP responses from other routers or servers on the local network. 3.7.2.12 Transmit IPX RIP Set this field to YES to transmit regular IPX RIP responses to other routers or servers on the local network. If set to NO, IPX RIP responses will only be sent as a result of receiving a RIP request. 3.7.2.13 Receive IPX SAP Set this field to YES if you wish to receive IPX SAP responses from other routers or servers on the local network.

Unit Status Traffic Analysis Network Loading Remote Management Unit Configuration MAC Filter Ethernet MAC Filter WAN MAC Filter Service Setup Events IPX SAP Filter IP Filter Ethernet IP FIlter Filter Setup WAN MAC FIlter Ethernet IPX SAP Filter WAN IPX SAP Filter There are filter tables available for both the Ethernet connection and WAN link.
4.7.2 IP FILTER (WAN or Ethernet) Both the Ethernet and WAN ports on the router can have an individual IP filter table. If IP filtering is active then any packets received are checked against the filter table before processing by the Router. Each port IP filter table can have 64 entries. When the first entries are made they will not become active until the table screen is exited. Any future input will become active immediately.
MENU SELECTION SRC MASK DEST ADDR DEST MASK PROT S.PRT D.PRT DESCRIPTION The IP mask associated with the Source Address in hexadecimal format. Left blank if ALL source addresses are forwarded. The destination address of IP packets to be filtered. A network address, individual IP address or ALL may be specified. The IP mask associated with the Destination Address in hexadecimal format. Left blank if ALL destination addresses are specified. Indicated the protocol this entry will filter on e.g.
This is the source IPX network number of the service. Services will not be entered into the internal SAP table if the RIP table has no entry for the route to this address. Node Address (48 bits) This is the Ethernet or Token Ring MAC address from where the SAP originated. Hops (16 bits) This is the number of Routers that must be traversed to reach this service. Every time this SAP passes another Router this count is incremented to a maximum of 16.
4.7.4 IPX HEADER FILTERS There is a single IPX header filter that can control the forwarding of packets from each port. The user can select if this filter is applied to packets received from either or both ports. The filter can have up to 128 entries. If IPX filtering is active, then any packets received are checked against the filter table before processing by the Router. The operation of the IPX filter does not effect RIP and SAP packets as they are processed directly by the Router.
MENU SELECTION NETWORK MAC NODE ADR SOCKET P.T RSLT DESCRIPTION Source or destination IPX number (eight digit hexadecimal.) Ethernet MAC address of the network adapter card (twelve digit hexadecimal. File servers are usually designated 000000000001. Designates a conversation between two addresses.

APPENDIX B APPROVAL REQUIREMENTS There are no specific approval requirements for the Router Option - refer to Echo LANlink User Manual for general approval requirements. Echo LANlink Router Option User Manual Issue 1.
APPENDIX C EMC REQUIREMENTS There are no specific EMC requirements for the Router Option - refer to Echo LANlink User Manual for general EMC requirements. Echo LANlink Router Option User Manual Issue 1.
APPENDIX D REAR PANEL LAYOUT The layout of all ports on the rear panel of the Echo LANlink with Router Option fitted is shown in the diagram below: Echo LANlink Router Option User Manual Issue 1.
APPENDIX E AUI PORT (15-WAY D-TYPE) PINOUT The AUI port connector is a 15-pin, D-type socket.
APPENDIX F 10BASE-T (RJ45) PORT PINOUT The twisted-pair Ethernet port connector is a 8-pin, RJ45 socket, conforming to the 10BASE-T standard and suitable for connection to an Ethernet hub.
APPENDIX G IP FILTER EXAMPLES If IP filtering is active then all packets received are checked against the filter table before processing by the Router. Packets are also compared to the IP Filter Table when the IP Filter is set to Bridge. The IP Filter can have 32 lines or entries. An entry does not initially become active until the user exits the menu. Future amendments are acted upon immediately after entry.
G.1.1 Examples To pass any packet coming from the Class A 89.0.0.0 network you would enter: SRC ADDR 89.0.0.0 SRC MASK FF000000 The mask of FF00000 limits the comparison to the first 8 bits of the incoming address. If a Class B address of 130.140 has a subnet with 8 bits to provide the network/subnet of 130.140.5, then to filter any packet from this subnet you would enter: SRC ADDR 130.140.5.
Ports can be given a specific value or the user can use wildcards to pass all values. Various services use a specific port number e.g. Telnet uses Port 23, FTP uses port 21. RFC 1700 gives a list of standard port values. G.3.1 Examples If 130.140.5.10 wishes to be able to Telnet to 130.140.6.32, but does not wish 130.140.6.32 to be able to Telnet back to him the following line should be used: SRC ADDR 130.140.5.10 SRC MASK FFFFFFFF DEST ADDR 130.140.6.32 DEST MASK FFFFFFFF PROT TCP S.PRT ALL D.
APPENDIX H IP SUBNETS An Internet Protocol (IP) address is 32 bits long and is split into two parts. The first part is the network number and the second part is the unit number. Combined they make a unique address. An address with a different network number can only be reached via a Router. The way the IP address is split into these two parts varies on the upper bits of the network number. This fixed split is defined as three classes.
