Within Wireless LAN were using ATM as transport network between 2621XM hotspot router and the SSG. In the past we used NM-4E1 on 2621XM. Due to EOS we needed to use AIM-ATM-4E1 now. The configuration of the new ATM interface card is different from NM-4E1. Where can I find information how to configure AIM-ATM-4E1 on 2621XM for ATM (PVC and IMA)?
