There are two sequences defined, al09 and al10. These sequences can be found here:

Assuming that you are not an MPEG member, I can just state that this code is part of the reference software being available by ISO (ISO/IEC 14496-5:2001). The error-resilience code is available in the subdirectory aacErrRobTrans (encoding part) and in the subdirectory mp4AudVm (decoding part). The low delay AAC code is available in the subdirectory mp4AudVm (encoding and decoding part).
Best regards,
Ralph
