Data Path Interface To Utopia Level 1 Header Translation Device

The IDT77V012 provides full header translation functionality along with Data Path Interface (DPI) to UTOPIA Level 1 translation for Switch and DSLAM designs using the IDT SwitchStar. The address search and replacement algorithm is performed using a VPI Tunneling or Full Header format on 8, 12, 24, 28 or 32-bits of the header. This added flex- ibility makes it suitable for both UNI and NNI formats. External memory is required to perform the header translation (receive direction only), which will support up to 16K connections using a 256K x 32 SRAM The new header, which is obtained as a result of the search, CAN be used to overwrite the existing cell header in the receive path. A four byte TAG CAN also be added to aid in routing cells. By Unkown
