White Rock Networks is adding high-density DS1 and 10/100 Fast Ethernet support to its VLX2020 OC-48/192 SONET platform. The new ETS2 tributary shelf plugs into White Rock's VLX2020 Main Shelf, creating an OC-192 SONET ADM with DS1, Fast Ethernet, DS3, Gigabit Ethernet, and OC-n services in a single network element occupying only five rack units in height. Up to 672 DS1 or 192 Fast Ethernet services (in addition to multiple OC-n, Gigabit Ethernet and DS-3 services) can be delivered directly from a single OC-48/192 SONET network element. Each DS1 can be directly mapped into either a DS3-mapped STS-1 or a VT1.5-mapped STS-1 SONET payload. White Rock Networks said this unique direct DS1-to-DS3 mapping lowers carriers' CAPEX costs and simplifies their network architecture by integrating the DS1-to-DS3 M13 multiplexing function directly into the DS1 interface card. This eliminates the need for separately managed M13 multiplexers or the DS3 transmux cards required in competitors' ADMs when carriers want to hand off customer DS1 services as DS3s elsewhere in their network. The new ETS2 tributary shelf, which will be available in August, can also be combined with White Rock's other optical network building blocks.

- In March 2003, Tellabs announced a strategic investment in White Rock Networks. Under the agreement, Tellabs will market and sell a customized version of the White Rock VLX2020, which is a compact next-generation SONET add/drop multiplexer. Tellabs also adds to its portfolio a customized version of the White Rock VLX1010, a WDM platform that supports a seamless migration from coarse WDM to dense WDM. Financial terms were not disclosed.
In December 2002, White Rock Networks closed $42 million in fourth-round venture funding for its next-generation optical transport systems for the local metro transport market.
White Rock has taken a unique approach to the MSPP problem by breaking it into pieces - modular, stackable product elements. White Rock also features a software-based control plane that transforms their modular "building-blocks" into a single network element. White Rock Networks has raised $144 million since its inception in 1999.
