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.

Hi.
VWIC can also be configured as WAN interface loosing Voice capability.
Curtin, you can try to decrease speed on your channel-group
