Transparent Mapped GFP-T IP Core
Preliminary Product Brief
Features | Block Diagram | Device Utilization | 
Description
The GFP-T Core receives decoded 1 or 2 Gbit 8B/10B Fibre Channel client characters and maps them into fixed-length transparent GFP superblock frames according to the Transparent GFP specifications set out in ITU-T G7041.Y.1303(12/2003). The core is optimized for Altera devices.
Features
- Compliant with ITU-T Rec. G.7041/Y.1303 (12/2003) Specification for Transparent GFP
- Supports Client Data at 1 or 2 Gbps rates
- Supports Transparent Fibre Channel with Null Extension Header & no Payload FCS
- Maps Fibre Channel onto a GFP-T Frame of 13 Superblocks: (13 x (65Bx8 + 16) + 8x8)) = 13x536 + 64 bits/frame = 7032 bits/frame per the recommendation of Appendix IV in G.7041
- 7032 bits/frame size allows for insertion of 1 Client Management Frame (CMF) between data frames for maximum SDH path capacity in VC-4-6v (for 1gbps FC) and VC-4-12v (for 2gbps FC)
- Datapath interfaces adhere to Altera’s Atlantic Specification
- Register Interface for CMF insertion/extraction, core configuration and monitoring
- CMF Payload Information Field set at 8 bytes
- cHEC error detection and single-bit error correction.
- eHEC,tHEC, & CRC SuperBlock error detection
- Automatic 65B_PAD/10B_ERR code insertion
