A method and apparatus for enhancing frame alignment using cyclic redundancy check ("CRC") corrections are disclosed. In one embodiment, a process of frame alignment searches a predefined bit pattern within a first multi-frame structure and provides an assumed frame boundary after identifying the predefined bit pattern in the first multi-frame structure. While calculating a CRC value in response to the assumed frame boundary, the process further corrects the CRC value in accordance with a saved residue and F-bits identified by the assumed frame boundary. The assumed frame boundary is subsequently verified by comparing the calculated CRC value with embedded CRC value obtained from a second multi-frame structure. |
