how can I use the DB60 cable to make the connection between 2 routers

[victorjob]

I bought 2 routers of 1601R and 2501 recently, how can I use the DB60 cable to make the connection between 2 routers on serial0? ‚hhave set the no shutdown and ip address but it
always show the Serial0 is down, line protocol is down.

What can I do?? thank you very much !

You must be using a DTE cable for one router and a DCE cable for the another one. The DTE is the male cable, and DCE is the female one. You may also use the "sh controller serial " command: it shows dte/dce mode.
In the router using the DCE cable, under the interface serial configuration, you must set the clock rate, e.g. :
interface Serial0
ip address 10.10.1.2 255.255.255.0
clockrate 64000

 

[victorjob]

I have added this DB60 between two routers?
Is this cable DTE cable or DCE cable?
What can I do?

Which cable should I take?

Cable company :

http://anthonypanda.com/prodlst.php?cat_id=1

Thank you very much!!

 

[fmonteiro]

The 2501 has a DTE cable:
cisco2501#sh controller serial
HD unit 0, idb = 0x2433C4, driver structure at 0x24A9A0
buffer size 1524 HD unit 0, V.35 DTE cable

Please, post the sh controller for the 1600. I will check it for you.

The 1600 is also using a DTE cable. Look at the last line below. This is your problem: you are using a DTE/DTE cable and you need a DTE/DCE cable, because one side must generate the clock. Are you using two cables? How do you connect your cables?

I used the a cable of

http://www.citac.edu.hk/adv/b2b6ft.jpg

One side connect to 1601R
One side connect to 2501

What cable or adaptor should need to add?

Thank you

 

[victorjob]

I have solved this problem.
My DB60 cable is DTE/DTE. I have changed the new cable, that is ok..

Thank you for your kind helping.

Good to know. You are welcome!
