This object contains the CBR specific VC Configuration table. There is one cbrDS1E1VcConfEntry associated for each CBR VC connection provisioned within the shelf. This table uses vcPortSlot, vcPortPort, vcPortTransmitVpi, vcPortTransmitVci, vcPortReceiveVpi, and vcPortReceiveVci as an index which is defined in the vcBaseTable of the C-PRODUCT BASE MIB. This index value uniquely identifies the CBR VC connection to which this entry is applicable. NOTE: The associated Circuit Emulation Service (CES) MIB defined by the ATM forum restricts the VC index to a single 32-bit scalar value. In support of this MIB, the CES MIB index retains the same indexing information as the enterprise MIB (with the exception of using vcPortReceiveVpi and vcPortReceiveVci) but has been bit-mapped using the following construction: vcPortPort bit 0..3 vcPortSlot bit 4..8 vcPortTransmitVci bit 9..23 vcPortTransmitVpi bit 24..31
