The ws-x5158 (ATM OC3) works well, but throughput maxes out around 
80Mbps bi-directional traffic and 50,000 pps with 64-byte frames (RFC 
2684). I would run a IOS version on the ATM module of 
c5atm-wt-mz.120-28.W5.30.bin or later to avoid a bug with Ethernet 
frames not being padded to 64-bytes. If the far end device is a Cisco 
router using 1483 bridged PVCs over ATM with CEF enabled you'll 
encounter the problem.

CSCdp82703  - Packets less than 64 bytes should be padded on 1483 PVCs
