Network Interface Connection
Direct cable connection method
Cross cable connection method
Cross Cable –Used for 1:1 connection between same equipment in the network.
Direct Cable - Also called as 1:1 straight cable and used for connecting
other equipment from the network.
* How to differentiate between Direct cable & Cross cable
The UTP cable consists of 8 stripes of wire and the wire actually used for data transmission in the
LAN environment is the reception (Rx) No.1 and 2 wire and the transmission (Tx) No.3 and 6,
consisting of 4 strands. They are classified into two types depending on method to connect wire for
reception and transmission.
