MW1122 Administrator Manual Copyright Nokia Networks Oy C33902001SE_002-122.2.8 Point-to-Point Protocol over Ethernet (PPPoE)Standard PPPoE mode is used when MW1122 is operating as a bridge.PPPoE protocol defines how PPP sessions are mapped into Ethernetpackets. When MW1122 operates as a bridge, this protocol istransparent to MW1122.2.2.9 Payload encapsulationsBoth routed and bridged protocols are encapsulated in the ATM link byusing either RFC 2684 LLC/SNAP encapsulation or VC multiplexing.MW1122 also supports PPP over AAL5 encapsulation, in whichrouted protocols are first encapsulated in PPP (RFC 1661). PPP is thenencapsulated in ATM according to the IETF PPP over AAL5 usingRFC 2364 VC multiplexing or LLC/NLPID encapsulation.2.2.10 Access list authorisationWhen a wireless LAN is used, it is important to be able to control theclients accessing to MW1122. Therefore, MAC-address-based accesscontrol may be used. It prevents all communications to a such clientwhose MAC address does not appear on the access list. When a newclient is brought to the network, its MAC address needs to be added tothe access list. This can be done manually through the local commandline interface (CLI) or with a Web browser management.2.2.11 Wireless LAN and radio interfaceMW1122 supports wireless LAN to be used as one of the interfaces.The wireless LAN utilises Nokia C110/C111 Wireless LAN PC cardwhich needs to be inserted to the designated PC Card slot on the backpanel of the modem. Only Nokia C110 or C111 Wireless LAN cardscan be used. Without a wireless LAN card, MW1122 operates as anormal ADSL terminal with one 10Base-T Ethernet interface. Thewireless LAN card can be inserted to the PC Card slot while themodem is operating and the wireless LAN connectivity will beachieved without restarting the modem. Only the WLAN subsytemmust be reseted through the web interface or the command lineinterface.Wireless LAN used in MW1122 is based on IEEE802.11 standardoperating at 2.4 GHz radio band. The band has been divided intosubchannels which are dependent on local regulations. Typically, inEurope, there are 13 and, in USA, 11 channels. The transmission
