Frame Relay Discard Eligible Packets

[odot]

Why would a 56k circuit mark packet's as DE when the data is only transferring at a rate of:
30 second input rate 5000 bits/sec, 8 packets/sec
30 second output rate 6000 bits/sec, 10 packets/sec.
There are also no input or frame errors but increasing DE input errors. Any suggestions?

Any frame relay application I have ever run (and to be quiet honest, I haven't done too much of it), I have had the option of setting the DE buffer to a longer time interval to make sure all the packets make it out of the buffer before they are discarded.
Is this a point to point or multiplexed off of a T-1 running frame relay?
What IS your circuit configuration?

Thanks so much for responding!
I am on the network site of this 56k point-to-point circuit. I was seeing this in our router when I ran the sh frame-relay pvc cmd but the traffic was so low I didn't understand why packets were being discarded. Would setting the DE interval on the frame-relay side be done by the telco? In 7 minutes the router received 32 DE packets on the input side. No other errors on the router or FECN's or BECN's.
