1. USER MANUAL G 703 FastEthernet Interface Converter TAHOE 283 TAHOE FREEDOM OF COMMUNICATION 1 Introduction Tahoe 283 converter allows connecting of two LANs through an El line terminated with balanced G 703 interfaces Converters work as transparent bridges that is both interconnected networks appear as a single LAN as if both were plugged into the same Ethernet switch Converter automatically learns which Ethernet addresses are heard on one and which on the other side As a result local traffic is not sent through the WAN link converter discovers packets destined for the other LAN and only those are directed to the G 703 interface 2 Interfaces power power connector switch Ethernet G 703 Rear view of the converter 2 1 G 703 Interface 21 The G 703 interface is equipped with a RJ 45 connector having following pinout RX TX TX O NIA UTT BWIN The RX pin of the converter should be connected to the TX pin of the other device the RX pin to the TX pin TX to RX and TX to RX 2 2 Ethernet Interface Fam The Ethernet interface is used to connect the converter to the LAN It may work at 10 or 100 Mbps and in either half or full duplex mode The choice between these modes is done automatically Converter should be connected to a switch using a straight p2. atch cord and to a PC or a router using a cross over patch cord iii 3 Status LEDs On the front panel there are four LEDs indicating device status O WAN Link when lit indicated synchronization to the other G 703 device O WAN Act blinks to signal the activity of the G 703 port O LAN Link when lit indicates proper Ethernet connection between the converter and the switch or other device O LAN 100M when lit indicates successful negotiation of 100 Mbps transfer rate on the Ethernet port O LAN Act blinks to signal the activity of the Ethernet port 4 Technical Data O processor ARM memory 8 MB SDRAM O MACtable size 10 000 entries automatic entry removal after 30s G 703 port unframed 2048 kbps balanced 1200 HDB3 line coding 43 dB receiver sensitivity up to 2000m reach dimensions 200 mm width x 130 mm length x 45 mm height O power supply 15V 400mA external power supply included o environmental conditions storage temperature 20 C to 65 C humidity 5 to 95 operation temperature 0 C to 50 C humidity 0 to 85 aE E E 5 Declaration of Conformity TAHOE Piotr Kaczmarzyk ul Uniwersytecka 1 50 951 Wroclaw Poland We declare that the product Tahoe 283 complies with the regulations of the following European Directives 73 23 EEC low voltage safety requirements o 89 336 EEC EMC requirements o 99 5 EEC radio telecommunication terminal equipmen
