Hi Ken,
sorry if I am pointing out something obvious, but what sort of cable are you using for the back-to-back PRI connection? The wiring for such a cable is different from regular ethernet and unless you have a few lying around, you would need to create them yourself. The pinouts for such a crossover cable are:
END 1
PIN 1 ORANGE/WHITE
PIN 2 WHITE/ORANGE
PIN 4 BLUE/WHITE
PIN 5 WHITE/BLUE
END 2
PIN 1 BLUE/WHITE
PIN 2 WHITE/BLUE
PIN 4 ORANGE/WHITE
PIN 5 WHITE/ORANGE

Hoping to get some advice with a frame relay issue in my home lab.
I'm using 3 routers in a back-to-back configuration with a separate FR/PSTN switch. The connection between HQ and BR2 is up/up, but I cannot figure out how to get the link up between HQ and BR1. When I plug in a known good working cable, link and protocol come up, then protocol goes down. I've tried the following and am still at a loss.
* Checked cables (swapped cable between HQ & BR2)
* Reseated all cards
* Performed loop diag and extended ping on all interfaces - no input/crc errors
* Applied 'no keepalive' (interface comes up/up but status sent/receive messages do not increment)
* Applied 'clock rate 128000' on FR switch but it doesn't appear in 'sh run'
All LMI interfaces show as CISCO. BR1 right now is configured on the physical int but even on a sub-interface and a reboot it still doesn't work.
