CML Receiver Interface Sub Blocks
The following sections describe the sub-blocks used in the CML receiver interface.
RSEF_SLICE Block
The RSEF_SLICE block contains the RSEF. The SERDES supplies a generated receive clock
and data to the RSEF. Data from the SERDES is carried as 8-bit symbols for SONET/SDH
scrambled mode or as 10-bit symbols for TelecomBus mode.
SONET/SDH Scrambled Data, 8B/10B Encoded Data Framer (RSEF)
A total of 24 RSEF blocks are instantiated in the TUPP 2488 device. There are eight RSEF
blocks on the line side of TUPP 2488 for the four working and four protect Line Ingress Serial
RASIO™ CML links. Likewise, there are 16 RSEF blocks on the system side of TUPP 2488 for
the eight working and eight protect System Egress Serial RASIO™ CML links.
The RSEF block performs character alignment and frame alignment on a received unaligned
SONET/SDH data stream. The RSEF block recovers character and frame alignment in two
modes: Serial TelecomBus 8B/10B encoded data, and SONET/SDH scrambled data.
