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.

DCE vs DTE and serial connections - Cisco Community
November 17, 2020 - For home lab with back to back serial cable (special cable made for back-to back connection), you should provide clocking with clock rate command on one of 2 routers (per link). That will be your DCE end while other end of a link is DTE.

r/ccna on Reddit: Cant use DCE or DTE cable on Cisco 1941 router (packet tracer)
October 30, 2020 -
I have a lab for homework where i have to use a serial cable, DCE or DTE im not sure. The teacher went over it and it looked like he added a module to the back right side and then it would work.
im tring that on both the left and right side and it still dosent work. I watched youtube videos where the guy did the same thing and it worked for him no problem. i tried 2 different versions of pacet tracer too.

Power down the router. Click & drag the HWIC-2T module to one or both of the empty slots, then power the router back on. You can now attach a DCE or DTE cable to one of the serial interfaces.

The serial interface will not come up like an ethernet interface will. For the serial interfaces, you must establish a connection between two points in order for the interface to become operational. Connect the serial cable between two routers, then enable both interfaces, the link will come up. You can then assign IP addresses if desired.

DCE stands for data circuit-terminating, data communications, or data carrier equipment - this is a modem or more generally, a line adapter.
DTE stands for data terminal equipment which generally is a terminal or a computer.
Basically, these two are the different ends of a serial line.

February 23, 2026 - Even on cisco routers, organizations prefer PPP protocol over HDLC protocol due to its advance features and benefits. In this lab, we will configure a Serial Connection between the routers. We will set up a clock rate at 56000, which will provide the speed of 56 Kbps. In a real world, the DCE side of the cable is configured by the service provider.

I’m trying to configure a serial connection between two routers. The connection requires DTE (R1) to DCE (R2), in PT these are only two connections. DTE>DTE and DCE>DCE. What can I do here?

The connection side with the “clock symbol” should be the DCE.

one side should automatically take over as DCE. Look for the term "DCE" or "DCE" in the output of show controllers. It should be the the second or third line down. Try cabling R1 and R2 together. You should find one of them shows as DCE, and the other shows as DTE.
