1. USER MANUAL V 35 FastEthernet Interface Converter TAHOE 285 FREEDOM OF COMMUNICATION 1 Introduction Tahoe 285 converter allows connecting of two LANs through a line terminated with V 35 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 V 35 interface 2 Interfaces power power connector switch y n E oj po Rear view of the converter Ethernet V 35 2 1 V 35 Interface The V 35 interface is equipped with DB 25 connector A V 35 cable terminated with 34 pin male DTE Winchester connector should be connected here so the converter could be connected to a DCE device like a V 35 modem 2 2 Ethernet Interface 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 patch cord and to a PC or a router using a cross over patch cord 32. Status LEDs On the front panel there are four LEDs indicating device status O WAN Act blinks to signal the activity ofthe V 35 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 oO 4 Technical Data processor ARM memory 8 MB SDRAM MAC table size 10 000 entries automatic entry removal after 30s dimensions 200 mm width x 130 mm length x 45 mm height power supply 15V 400mA external power supply included environmental conditions storage temperature humidity operation temperature humidity 20 Cto 65 C 5 to 95 0 C to 50 0 to 85 5 Declaration of Conformity TAHOE Piotr Kaczmarzyk ul Uniwersytecka 1 50 951 Wroclaw Poland We declare that the product Tahoe 285 complies with the regulations of the following European Directives o 73 23 EEC low voltage safety requirements o 89 336 EEC EMC requirements o 99 5 EEC radio telecommunication terminal equipment requirements The compliance of Tahoe 285 with the requirements of the above mentioned directives is ensured by complete application of the following harmonized European Standards o EN60950 2000 o EN55022 1998 EN61000 6 1 2002 EN61000 6 3 2002 Signed Piotr K
