Utopia Level 1 or 2 compatible MPHY Interface
Incoming HEC verification and correction (optional)
Generation of a new HEC byte
Format outgoing cells into multi-vendor serial TDM formats
Retrieve ATM Cells from the incoming multi-vendor serial TDM format
Perform cell delineation
Cell pre-processing
Provide various counters to assist in performance monitoring
TDM expansion ring to span multiple devices
Transmit scheduler (one per IMA group)
Generation of the TX IMA Data Cell Rate clock
