![]() ![]() When You Order The WAN Connection Cable, You Receive A Serial Transition Cable With A DB-60 Connector (Also Called Five-In-One Serial Connector) At One End And The Connector Appropriate For The Standards You Specify At The Other End. Some Of The Different Signaling Standards And Connectors That Might Be Found On DCE Equipment Include EIA/TIA-232, EIA/TIA-449, V.35, X.21, And EIA-530. Serial Ports On The Other End Of The WAN Connection Is Dependent On The Service Providers And The Type Of Their DCE Equipment. Serial Ports On Cisco Routers Use 60-Pin DB-60 Connector Or The Smaller “Smart-Serial” Connector For The Purpose Of WAN Connections. On The Contrary, Parallel Data Transmission Transmits Several Bits At A Time With Parallel Data Transmission. Serial Transmission Is A Method Of Data Transmission In Which Bits Of Data Are Transmitted Sequenctially Over A Single Channel. ![]() Some Routers Have Additional Ports Such As BD-9 Port For Token Ring Network And Isdn Basic Rate Interface (BRI) Port For Low Cost Dial-On-Demand Wan Connection, As Illustrated In The Following Picture.įor Communication, Wans Use Serial Transmission. THE FOLLOWING PICTURE SHOWS A ROUTER WITH THE MOST COMMON ROUTER INTERFACES: Ethernet AUI Port, SERIAL Port, CONSOLE Port And AUXILIARY Port. ![]() WAN INTERFACES (SERIAL, ISDN BRI): Are Made Through A Wan Interface On A Router To Service Provider To Distant Site Or To The Internet. MANAGEMENT PORTS (CONSOLE, AUXILARY): Provide A Text-Based Connection For The Configuration And Troubleshooting Of The Router.ģ. LAN INTERFACES (ETHERNET AUI, BD-9): Allow The Router To Connect To The Lan Media Through Ethernet Or Some Other LAN Technology Such As TOKEN RING OR ATM.Ģ. GENERALLY IN CISCO ROUTER HAVE THREE KINDS OF INTERFACES : 1. ![]()
