Frame Relay Uni Sig I Frames Tx Discarded

This attribute counts the number of SVC I-frames that are bound for the link but have been discarded. Discard reasons may be one of the following: 1. the frame length is beyond allow limit. 2. the SVC data link layer is in disconnected state. 3. the transmit queue has been purged because the queue length has reached the reset threshold. 4. the transmit queue or the queue waiting for acknowledgment has been purged because the link cannot be re-established. When this count reaches maximum, it wraps to zero.
