This MIB is used for configuring/provisioning SPVCs on
the ATM interfaces. This is used for ATM switch
connection management.
        
Terminologies used:
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.
PCR  - The Peak Cell Rate(PCR) traffic parameter specifies
       an upper bound on the rate at which traffic can
       be submitted on an ATM connection.
SCR  - Sustained Cell Rate.
MBS  - Maximum Burst Size.
MCR  - Minimum Cell Rate is the rate at which the source
       is always allowed to send.
ACR  - Allowed Cell Rate is the current rate at which
       a source is allowed to send.
RDF  - Rate Decrease Factor controls the decrease in the
       cell transmission rate
CRM  - Missing RM-cell count. CRM limits the number of 
       forward RM-cells which may be sent in the absence
       of received backward RM-cells.
CDF  - The Cutoff Decrease Factor controls the decrease
       in ACR assoicated with the CRM.              
        
CDVT - Cell Delay Transfer Variation Tolerance
        
CBR  - The Constant Bit Rate(CBR) service category is used
       by connections that request a static amount of 
       bandwidth that is continuously available during the 
       connection lifetime. This amount of bandwidth is
       characterized by a PCR value.
rt-VBR - The real-time Variable Bit Rate(rt-VBR) service
       category is intended for real-time applications,
       i.e.,those requiring tightly constrainded delay
       and delay variation, as would be appropriate for
       voice and video applications.The rt-VBR connections
       are characterized in terms of a PCR, SCR and MBS.
nrt-VBR - The non-real-time Variable Bit Rate(nrt-VBR)
       service category is intended for non-real-time
       applications which have bursty traffic 
       characteristics. The nrt-VBR is characterized
       in terms of a PCR,SCR and MBS.
UBR  - The Unspecified Bit Rate(UBR) service category is
       intended for non-real-time applications,i.e.,those 
       not requiring tightly constrained delay and delay
       variation. The UBR service does not specify traffic
       related service gurantees. The UBR service is
       indicated by use of the Best Effort Indicator in
       ATM User Cell Rate Information element.
ABR  - The Available Bit Rate(ABR) is an ATM layer 
       service category for which the limiting ATM layer
       transfer characteristics provided by the network
       may change subsequent to connection establishment.
        
CAC  - The Connection Admission Control(CAC) function is
       defined as the set of actions taken by the network
       at SVC establishment or by network management during
       PVC establishment in order to determine whether
       a connection can be progressed or should be rejected.
UPC  - Usage Parameter Control(UPC) is defined as the set
       of actions taken by the network to monitor and
       control traffic.
