Performance of Coding Scheme for Various Service Types in AAL2 of ATM-PON

The coding scheme according to service types in AAL2 of ATM-PON is proposed in this paper. The service types and the corresponding error correcting codes are indicated by two of six reserved bits in SSTED of AAL2. Several coding schemes such as BCH and convolutional codes are considered under using the same and different kind of coding schemes. As a result, the (127,120) and (127,106) BCH codes may be the best choice for voice and data service respectively among all the possible schemes.
