White Rock Acquires Seranoa for its Service Edge Concentrators

White Rock Networks, announced has acquired Seranoa Networks, a start-up based in Boxborough, Massachusetts, that supplies intelligent Service Edge concentrators. Financial terms were not disclosed. White Rock is provider of next-generation optical transport systems for metro markets.

White Rock said the acquisition substantially broadens its market coverage "since their products reduce the costs of terminating and transporting all of the data that comes into a carrier's network from beyond the fiber's edge." Seranoa's current products will become the White Rock VLX300 and VLX400 Service Edge Concentrators and will be supported by White Rock's existing customer service organization based in Richardson, Texas.

  • In May 2004, Seranoa Networks introduced a new family of Service Edge Concentrators designed to reduce the number of backhaul circuits used to deliver T1-based packet and TDM services to business subscribers over current SONET/SDH metro access networks. Seranoa's new IPeX Service Edge Concentrators are packet-aware switching platforms that could be deployed in a central office or collocation (co-lo) facility. The IPeX 200 performs IP-aware Layer 2 switching to multiplex and aggregate T1/T3-based IP/VoIP subscriber packet services onto standard clear-channel T3 (DS3) backhaul circuits. It offers 12 channelized or clear-channel T3 (DS3) interfaces, up to four of which can be configured as T3 (DS3) trunks with the remaining configured as IP subscriber interfaces. A larger IPeX 400 provides the same IP-aware Layer 2 switching benefits and also supports TDM DS0 grooming capabilities of a wideband 3/1/0 Digital Cross-Connect System (DCS) to optimize the delivery of traditional TDM services. The IPeX 400 offers 12 channelized or clear-channel T3s (DS3s) and up to two Gigabit Ethernet interfaces. It can be used to multiplex IP subscriber traffic with simultaneous grooming and aggregation of TDM voice and non-IP data onto shared backhaul links. Seranoa said this approach enables major improvements in SONET bandwidth efficiency and significantly reducing carrier backhaul costs for IP, TDM or integrated IP/TDM service delivery.

  • Seranoa was founded in 2000 and has raised $25 million in financing from St. Paul Venture Capital, YankeeTek Ventures, FA Technology Ventures and Advent International.

  • Seranoa is headed by Graham Pattison, who previously was President and CEO of Verilink Corp. The company was founded by Paul Kelley, who previously was also a founder and Vice President of Engineering of Net2Net (acquired in 1998 by Visual Networks).
