CCIE Voice lab question

[Curtis Fuentes]

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

Hi,

       Keep in mind that I am using Vwic cards not WIC cards.

Thank you

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.

Hi Carlo,

    I   used the pinout you gave me the ligh on the cards are green. The issue that I have now isthe interface is up but the protocol is down.

Hi Curtis.

Now the problem is Frame Relay related I guess..

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

Bye
