Semiconductor Solutions for High Speed
Communications and Fiber Optic Applications
The Frea™ is a single-chip OC-192c/48c device that sup-
ports Resilient Packet Ring (RPR) protocol on both
SONET/SDH and 10GbE PHYs.
RPR, a layer two Media Access Control (MAC) technology,
significantly increases the bandwidth efficiency of service
provider networks by utilizing twice the capacity of tradi-
tional SONET/SDH rings. RPR delivers dynamic bandwidth
management while preserving the same kind of protection
and resiliency found in SONET/SDH networks.
The Frea chip integrates RPR MAC, PoS (Packet-Over-
SONET) framer and XAUI SerDes (Serializer/Deserializer)
necessary to deploy RPR rings in Metropolitan Area Net-
works (MANs) and Wide Area Networks (WANs). It also
eliminates external memory by including 1 MB of memory
on-chip for RPR operation. The Frea chip supports both
IEEE 802.17 RPR standard Draft 2.1, and RFC 2892 SRP
protocol. It also operates in a PoS framer-only mode,
which allows carriers unparalleled flexibility to build legacy
PoS networks that can later be configured to RPR through
a simple software upgrade.
Detects SEF, LOS, LOF, LOP, and
LOC
Monitors line AIS-L, RDI-L, and REI-L
Handles J0 and J1 processing
Calculates, monitors, and counts B1,
B2, and B3 errors
Supports SF/SD BER algorithm
Supports REI-P error counting and
RDI-P monitoring
Supports path unequipped and pay-
load label mismatch
Meets ITU G.707, GR-253, T1.105
standards
PoS Features
PoS on STS-192c/48c
Option of CRC-16 or CRC-32
HDLC/PPP over SONET/SDH per
IETF RFC 2615, RFC 1662
RPR Mac Features
