ATM with ForeRunner (or Marconi) LE155

Hi folks,

I'm trying to connect, for lab testing, two cisco 7200 with wic PA-OC3
through an old (but working like a charm) ForeRunner LE155.

The topology is like that:

RouterP ---> | 1D1 ForeRunner 1D4 | <--- RouterC

If I well understood, I've to:

1- create two vpc:
Input Output
Port VPI Port VPI UPC Prot Name
1D1 30 1D4 30 0 pvc pvc-30-PtoC
1D4 50 1D1 50 0 pvc pvc-50-CtoP

2- create two vpt orig/term? how? This is a good output?

Input Output
Port VPI Port VPI ResBW CurBW MinVCI MaxVCI VCs Protocol
1D1 50 terminate N/A 0.0K 1 511 1 pvc
1D4 30 terminate N/A 0.0K 1 511 1 pvc
originate 1D1 30 N/A 0.0K 1 511 1 pvc
originate 1D4 50 N/A 0.0K 1 511 1 pvc

3- create vcc ... but how?
with this (maybe wrong) configuration, I create only:

Input Output
Port VPI VCI Port VPI VCI UPC Protocol Name
1D1 50 1 1D4 50 1 0 pvc N/A
1D4 30 1 1D1 30 1 0 pvc N/A

I hope you could help me. Any advice will be appreciated.
Best Regards
Andrea
