It enables Multiservice offerings of
both voice and Ethernet/SAN data services. Its contains a scalable switch fabric that
can scale from 2.5G to 10G, while its in-service capacity can be upgraded from low to
high-density DS1/DS3 circuit, as well as OC-12 to OC-48 and OC-192.
The Metropolis DMX can reduce the requirement for separate routers and data switches
by merging SONET and Ethernet functionality onto a single platform. It also supports
SAN distance extension with native FC/FICON (1G or 2G) or ESCON interfaces.
Nortel Nortel was also an early and vigorous proponent of the IEEE 802.17 standard.
They were founding members of the RPR Alliance and Editors of the standard.
Their primary RPR offering is the OME 6500. It enables service convergence with the
368 Chapter 12
availability of integrated, standards-compliant resilient packet ring (RPR) technology
on the OME 6500.
RPR capabilities on the OME 6500 include support for multiple Ethernet rings of up
to 10Gbps and the ability to provision up to eight classes of service on a per customer
and per application basis. Nortel was one of the first vendors to commercially deploy
RPR-based technology in 1999.
