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 adds the capability of connecting two Local Area Networks (LANs), via the E1

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 bandwidth is allocated in 64Kbps tim

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. This means that as well as connecting two remote LANs, the Echo LANlink can also carry PABX voice traffic (using D&I option card or ADPCM option card), and data traffic bet

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 require

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. 3.5 Data Connections The Ethernet connection is made using either the AUI (15-way D-type – see Appendix E)

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. Save
