The MIB module for frame relay connection
statistics.
        
Terminologies Used:
        
 SIW    - Frame-Relay-to ATM Service Interworking
         
 FECN   - Forward Explicit Congestion Notification.
          The FECN bit in Frame Relay header communicate
          network congestion to the endpoint in the forward
          direction.
        
 BECN   - Backward Explicit Congestion Notification.
          The BECN bit in Frame Relay header communicate
          network congestion to the endpoint in the backward
          direction.
        
 DE     - Discard Eligibility. The DE bit in Frame Relay
          header communicates the loss priority. A marked 
          frame with a DE bit value of 1 is considered
          less important than other frames in transmission
          and should be discarded before frames with a 
          DE bit value of zero.
        
 Tagged - Some of the statistics objects described in 
         this MIB are applicable where the 
         information is Set by the Switch/Service-Module.
         These objects contain word 'Tagged' in the name.
        
         For example : 'rcvFramesTaggedFECN'; This is the
         counter where FECN is set by the Switch in
         the frame received from the network. FECN was
         not set in the frame from the Network.
        
         The bit Set by the switch on an incoming or outgoing
         frame is called 'tagged' in this mib.
