The purpose of the DTE and the DCE in the Cisco CCNA

danscourses.com - What are the differences between the DTE and the DCE for the Cisco CCNA? In this tutorial, I discuss the purpose and characteristics of the DTE (the router) and the DCE (the modem or CSU/DSU) and how it is used at home and in the labs.

Thank you so much! This video really helped me fill in the gap for what the heck DTE, DCE, and clock rate really are, and how they work together.

[@sportdrew5]

Great visual perspective. Helped cleared things up. Thank you!

[@NIC_Pineiro]

Thanks so much! In the 200-301 this is mentioned as a foot note as it really isnt on the test anymore but I got some practice questions on kaplan that talked about DTE / DCE. Needed this one. thank you. Love how the fundamentals never change!

[@jairusan]

Awesome and simple. Thank you so much Dan.

[@kirkmham]

Love all your videos, you are the real MVP homie!!!

[@umdrsxs]

absolutely fantastic explanation!

[@RaidenHeaven]

I really had a problem with the whole "emulating thing" (2 routers).
Thank you for cleaning things out!

[@CheapBBQ]

Wow, this clears it up so much.
Cisco and people who teach Cisco make this as clear as mud. They just say "One side is DCE and the Other is DTE and make sure you set the clock rate."

Very good idea to do a portuguese version to my students, thanks for your great work.

This is what , without having physical equipment, i seemed, i m constructing a network. It was just like practical inspite of being in video. Thanks you sir.

"DTE is short for Data Terminal Equipment and DCE stands for Data Communications Equipment" :)

Isn't DCE = Data Circuit-terminating Equipment though?

Pro trick : you can watch series on flixzone. I've been using it for watching loads of movies these days.

Thanks for all your Videos Dan!!! you have been making easier my journey thru CCNA!!!! keep it going!!!

[@wael3706]

hey, did you get ccna cert?

[@weromontiel]

Yeah i got it, renewed for a second time and then swapped careers due life changes, but dancourses is your best bet for understanding ccna!!!!

[@wael3706]

@@weromontiel i see, is it easy to find a job with ccna cert ? with 0 job experience.
thanks for replying after 8 years btw haaha

[@weromontiel]

@@wael3706 hahhaha not a problem, for some reason youtube sent me the notification for your comment a little bit late. It is easy if you have the right connections but if not, Your best option to start getting into the networking realm without experience, find a job in a help dek that have networking as a help desk L1 networking guy, help desk work environment is crazy, everything is urgent, everything is important, but you gain experience FAST! Like really fast! Is the best and faster way to obtain knowledge! And experience and been on a help desk gives you a solid experience for your resume, trust me on that one. Be sure to understand well enough what road you will want to take in the future within networking (wireless, routing/switching, tshoot, design, etc) that is going to make your life easier in the long run so you can focus your mind and energy in what really is important to you. It will be easier to find a job without experience in a help desk tbh. Then once you have the experience and knowledge you can move to a company and work on the networking department, things will be a little bit more chill but will be good for the long run. If you have any other question let me know, I am not the most knowledgeable guy but I have had my experience lol

[@wael3706]

[@danscourses]

On a home scenario, your ISP has pre-configures the modem and set the clock rate.

[@thaime0]

Thanks you very much for this one !

[@fayyazahmed7344]

Thanks.. Nice Way to Teach...

[@naseemalam2295]

Hi Dan, i was just curious, how would DCE DTE work in your house for example? In many instances nowadays your router acts as your modem as well. Is a clock rate still applied and the router still acts as the DCE? Or there is no DCE DTE applied?

[@incrediblebrotha4779]

I'm of course not Dan, and I'm now studying for my CCENT/CCNA cert and came across this DTE/DCE in my labs. After watching this video, if a customer site has a multifunction network device, its still considered a DTE since its on the customers end site vice the ISPs end site.

[@yxvm]

basic and on point! Thanks!

[@XxLonelyxX]

Question. So if i did a home setup how do i know to determine the clock rate and bandwidth?

hey, router with built in CSU/DSU is it dte or dce? If it acts as csu/dsu and a LAN router, to route traffic to end devices? Or this situation is impossible? Only dce csu/dsu router must be connected to dte router only?

[@eyemwired]

i downloaded a packet tracer 53008, it does not have all the devices i.e. wireless router, dsl modem etc. what do i do?

[@Occel0t575]

thank you very much !!

[@mohamedkarti6820]

Thank you

[@FaridPangos]

I got confused :( Does it mean that the DCE is your DSL Modem at home ? So if in someway you change its firmaware you can get set the clockrate ? :S

[@ramyax]

hi first of all thanks for your explanation, im start to see it. The matter is that i was searching by the web and i cant find a real working production network scheme, all people refer the DCE like a NORMAL modem for a house or small company, i would lke to know about the real modems ATM, FRAME RELAY, ETC ETC. "I know that the protocols are configurable, but that kind" that use a big company not a house modems, this kind of house modem i think is not usable for IT student learning, i would like to know how it looks in fuction and the cable from the service and connector in case fiber or not. thanks

[@Yukiyukiyukichi]

Can a DSL modem or a cable modem also be CSU/DSU?

[@ramirez368]

A CSU/DSU converts digital signals from a router to a leased line; a modem converts digital signals from a router to a phone line........two questions for DAN first is the CSU/DSU and the modem are different devices and can you elaborate more on this answer from a CCNA topic and it is the correct answer.

[@phosgene87]

I was asking myself this question yesterday, then this pops up on my news feed. Are you a mind reader?

What’a the clock rate?

[@inmortal009]

awesome thanks

[@Drift_91]

Your use of a DSL modem confused me at first because it's not a DCE. The ISP's DSLAM is the DCE because it sets the clock rate that the modem has to synchronize itself with. A DSL or Cable modem is an end user device because it's the "client" of the DSL or Cable connection. The connection between the modem and the router over Ethernet is "negotiated" between the two devices and the lowest that the two agree on is selected. So between a modem and a router there is no DTE or DCE.

[@lucas93177]

I still son't understand why it is for.. DSL leased line cable what...

[@jay-ng]

So why does provider need clock and how does that affect the connection?

[@samuelbarrett9581]

Generally the clock rate need to be the same on both ends of DTE/DCE so they can negotiate the same speed. It wasn't clearly defined but as far as I know The DCE generates the clock rate and GIVES it to the DTE to synchronize. Similar to auto negotiation.

[@network_king]

what program is that your using?

[@nem81]

It is Cisco Packet Tracer. I know this is an old question, but im answering in case anyone else comes across this.

[@misaellopez5825]

@@nem81 And, two years later your answer is still helping people, like me! Thanks!

[@Drift_91]

No, your ISP's hardware is the DCE. It sets the speed that you connect at.

DTE stands for Data Terminal Equipment and DCE Stands for Data Communications Equipment …

[@lupomjr5833]

I apologize but I am getting frustrated with this video. Is it just me or is this tutorial both too slow and too confusing to anybody else? For instance, what does it mean when the lecturer says "the DCE GETS a clock rate" and the "dte DOES NOT GET a clock rate"? In other words, who is the generator of the clock and how does it decide what the clock rate needs to be????
Can anyone please suggest a more "dumbed down" video about the subject?
