Answer - C - PBCC specifies data rates of 22 Mbps and 33 Mbps.

Key Takeaway: PBCC is a 64-state binary convolutional code used for a high-speed physical layer of a communication network. The proposed code provides improved performance in terms of signal-to-noise ratio and multi-path rejection. It includes binary convolutional codes with scrambling in a packet-based system.
