Sean, My understanding is that the 8510 SRP is pretty much the same as ASP of LS1010, it is a ATM switch fabric. That's why both the ASP and SRP can be installed in slot 13 of the Cat 5500, which connects to the 5G cell-switch fabric, not the backplanes. Internally, the 8510 line cards chop the frames into cells before sending them across the SRP , that's why you got the AAL5 error.
