This attribute is a unique index used by the CCAP to identify each of the 6 MHz bands of a given OFDM downstream channel (from the lowest 6MHz band of the Occupied Bandwidth to the highest 6MHz band of the Occupied Bandwidth). The CCAP assigns indices in frequency order from the OFDM channel's lowest to highest 6 MHz frequency band for each of the 6 MHz bands of the channel, using an index of 1 to represent the lowest frequency band of the Occupied Bandwidth. Thus, an index of 33 represents the highest possible 6 MHz frequency band of the Occupied Bandwidth of an OFDM channel. The CCAP also provides the power of the PLC channel and utilizes a value of 0 to represent the PLC channel in this table.
