                   Hi,



        I am building my lab for the CCIE voice exam. I am currently working on my frame relay PSTN. I am able to get my PSTN ports to come up, but I am having issues with my framerelay.I thin is a cable issue because the ports are down/ down. I was wondering what type of cables are need for the frame relay ports. I am following the IPexpert and using vwics.




Thank you

Hi Curtis.

Now the problem is Frame Relay related I guess..


Try to set clock on the dce side and see if it works

Hi.
You should use a DTE/DCE cable to achieve what you are trying.

Ops..

Sorry Curtis.


In my case  worked an RJ45 with the following pinout:


1-2-3-4-5-6-7-8 ---> 4-5-3-1-2-6-7-8



You can try it and hope this helps.


If you can, please post your config.



Regards


Carlo

Hi.


VWIC can also be configured as WAN interface  loosing Voice capability.
