Re: DCE/DTE serial null cable [7:20715]
Hai Nick, For the interface of the router you want to set as DCE add clockrate 56000(whatever) to the interface. Then that interface will be taken as DCE. You can verify whether it has become DCE by issuing show controllers command.

RE: DCE/DTE serial null cable [7:20715]
If you skip the Frame Relay encapsulation and use HDLC instead, all you got to do is provide the clock at the one acting as DCE: router-dce(config-if)#clock rate 64000 If you want to simulate a Frame Relay, you will need a third switch. One to act as a Frame Relay switch, and two to connect to the first one, creating a PVC between them. Hth, Ole ~~~ Ole Drews Jensen Systems Network Manager CCNA, MCSE, MCP+I RWR Enterprises, Inc.

RE: DCE/DTE serial null cable [7:20715]
There is DTE/DCE on both the physical level and the Frame-Relay level. So configure the link with a clock speed on the end that has the DCE end of the cable. Then configure the frame relay command as you have given below. The layer two DCE end does not have to be the layer one DCE end. Experiment to prove it. -Original Message- From: Nick Christofi [mailto:[EMAIL PROTECTED]] Sent: Friday, September 21, 2001 1:39 PM To: [EMAIL PROTECTED] Subject: DCE/DTE serial null cable [7:20715] Hey everybody, Have 2 2524's running in my lab, with the 60 pin DTE/DTE cable connecting the 2 serial ports, no DSU/CSU.
