ATM Cell Processor Functional Description
Intel IXF6048 maps ATM cells asynchronously into one or four SONET/SDH payloads, in
accordance with the ITU-T Recommendation I.432 and the ATM Forum BISDN-ICI Specification.
Intel IXF6048 complies with the latest ATM Forum User Network Interface (UNI) and ITU-T
I.432 specifications by implementing all the Transmission Convergence Sublayer (TCS) functions
necessary to adapt the service offered by the SONET/SDH physical layer to the service required by
the ATM layer. Intel IXF6048 also implements a GFC halt function, in accordance with ITU-T
Recommendations I.150 and I.361.
the SONET SPE and the ATM cell format, respectively.
Each receive ATM cell processor (RACP) performs HEC-based cell delineation, HEC checking
(and optional cell header correction), cell filtering, cell payload descrambling, and optional GFC
monitoring for halt bits. Each transmit ATM cell processor (TACP) provides cell rate adaptation
via idle cell insertion, HEC generation and insertion, ATM cell payload scrambling, and optional
use of the received GFC halt commands.
