7206 running IOS 12.0(21)S1 with a 2 Port HSSI Port Adapter in Simplex configuration. One port is for Uplink and the second one for the downlink. Frequently showing OUTPUT DROPS in spite of different queueing mechanisms applied. Encapsulation is FR ietf. Please throw some light on the cause of OUTPUT DROPS.

Here is a link showing why output drops happen and how to troubleshoot / minimize them. Without some specific interface "show commands" to see what type queuing you are using it's hard to say whats the exact problem.
Since this is only an downlink all outbound packets might just be dropped. I would think that these could be control packets (ospf/cdp/etc) getting dropped as well. Are you certain that all of these are turned off on this interface?
