This MIB module contains ATM Connection related
real time statistical counter objects. The ATM
connections are applicable to PXM1 service module.
in MGX82xx products.

Logical Channel refers to ATM Connection(or connection
end point).

Terminologies used:
    broadband interface - Logical port on PXM1.
    SCR  - Sustained Cell Rate
    BT   - Burst Tolerance
    PCR  - Peak Cell Rate
    CDVT - Cell Delay Transfer Variance Tolerance
	    GCRA - The Generic Cell Rate Algorithm(GCRA) is used to
	           define comformance with repect to the traffic
	           contract. For each cell arrival, the GCRA determines
		   whether the cell conforms to the traffic contract
		   of the connection.

    GCRA1 - GCRA  Bucket 1. For CBR and UBR connections, only
            GCRA-1 is needed to check for PCR, CDVT Conformance.

    GCRA2 - GCRA  Bucket 2. For VBR and ABR Connections, GCRA-1
            is needed to check for PCR, CDVT conformance and
            GCRA-2 for SCR, BT Conformance.

    EFCI - Explicit Forward Congestion Indication.
    QE    - Queue Engine(QE).
            This ASIC Provides the traffic management functions
            related to VC queues, QoS queues and interface
            queues. This management function is performed
            for both directions of traffic(ingress, egress).
    ingress - ingress traffic is defined as data flowing
              toward the switch fabric. Ingress data can come
              from either the Service Modules through the 
              backplane or the PXM1 Uplink back card.
    egress  - Egress traffic is defined as data flowing
              away from the switch fabric.
