Corrigent incorporates RPR with MPLS, PWE3, Ethernet, and SONET/SDH to deliver
a packet-based transport platform for metro and regional applications. Corrigent
has been an active advocate of RPR since it??™s inception as contributors to and editors
Resilient Packet Ring (RPR) 367
of the IEEE 802.17 standard. Corrigent provided the Steering and Wrapping portions
of the standard.
Fujitsu Fujitsu??™s Flashwave 4500 MSSP is a Multiservice switching platform that supports,
SONET, Ethernet over SONET (EoS), RPR, Generic Framing Procedure (GFP),
Virtual Concatenation (VCAT), and high/low order grooming and switching capabilities.
The 4500 allows carriers to offer a wide variety of traditional DS1, DS3, and OC-n
private line services, plus carrier-class 10-Mbit to Gigabit Ethernet Private Line (EPL)
services, on a single network.
12-port DS3 Transmux interface card enable services across a VT1.5 switch fabric of
the 4500 platform to maximize the efficiency of TDM circuits. DS3 Transmux cards can
gather hundreds of low capacity VT1.5 circuits from DS1 interface and multiplex them
into fully utilized, high capacity STS-1 payloads. Consolidating circuits this way before
they enter a digital cross-connect system (DCS) helps carriers postpone or eliminate
the capital expense of adding or expanding a DCS.
