XRT95L34IV Overview
The XRT95L34 is an OC-12/STM-4, Quad OC-3/ STM-1 POS/ATM Framer with integrated CDR’s. ATM direct mapping and cell delineation are supported, so are packets (PPP) over SONET for POS mapping and frame processing. The XRT95L34 contains an integral SONET framer which provides framing and error accumulation in accordance with ANSI/ITU-T specifications.
XRT95L34IV Key Features
