Does a complex gateway (IGX/ BPX) the check of AAL5 CRC in both directions, and
if yes, how the errors shows up (e.g complex gateway errors)?
Question aims on a Frame-relay connection which runs over a ATM Backbone.

Hi,
In your case the AAL5 PDU is assembled for data in both directions by the SAR mechanism on a particular trunk card like the UXM.
That means the CRC in the trailer of the AAL5 PDU is calculated in both directions by the same card.
Thank You
