I am not completely sure, but I do not believe these two cards will
interoperate. The PA-POS is a packet-over-Sonet module. Thus that box will
look to frame the layer 2 frames as POS frames - and it will use the entire
OC-3 for the one POS connection. The PA-A3 is an ATM module. It is looking
to fill it with ATM 53-byte ATM cells, and it is expecting to divide the
OC-3 bandwidth between whatever SVCs or PVCs have been created.

Just my thoughts - Rob.
