Cisco – What’s the difference between Serial DCE and Serial DTE link ciscopacket-tracer In the Cisco Packet Tracer we also see the Serial DCE and Serial DTE: but I don't know what's the difference between them. Best Answer One side of the link (DCE), has to transmit the clock signal, which controls the data rate, and the other side (DTE) receives the clock signal. R1 is DCE here: interface Serial0/0/0 ip address 10.0.0.1 255.255.255.252 clock rate 2000000 R2 is DTE here: interface Serial0/0/0 ip address 10.0.0.2 255.255.255.252 The difference between the two cables in packet tracer is just which side you click first: With the DCE cable, (red zigzag with clock) the side you click first will be the DCE, the second will be DTE With the DTE cable (red zigzag no clock) the side you click first will be DTE, the second will be DCE Whichever way you do it, you'll see one side of the cable shows the clock symbol: this is the DCE.
