Ceterus Networks Raises $20M to Fund Infrastructure Rollout

Richardson, TX, March 12, 2007

Richardson, Texas March 12, 2007 – Ceterus Networks, a leader in the flexible transport solutions for backhaul and enterprise applications, today announced a $20M funding round led by Intel Capital. Sevin Rosen and ComVentures, both investors since inception, and Aldus Equity, a new investor, also participated in the funding.

Ceterus Networks has created a unique solution for versatile, cost-effective Ethernet service delivery supporting both wireline and wireless service providers in their delivery of new data and voice services.  The new funding, will help with large customer infrastructure rollouts and market expansion.

“Ceterus continues to expand their market and customer base by solving some of the top issues faced by service providers,” Michael Howard, Principal Analyst & Co-Founder, Infonetics Research, Inc. “Ceterus customers are reaching cell sites and enterprise locations with Ethernet in a quick and reasonably priced way, which helps these carriers offer new data services, that satisfy customer demand, and thereby grow revenue. I am impressed by their ability to convince some of the largest incumbent carriers to standardize on their products.”

Ceterus’ Universal Transport System (UTS) enables cost-efficient, flexible backhaul of data and voice traffic from mobile wireless cell towers and enterprise locations. The Ceterus UTS bonds individual DS1s, E1s, DS3s or SONET/SDH links into a single “virtual pipe” using ITU-standard circuit bonding, offering highly efficient, high capacity connections over the already existing access circuits. Utilizing Ceterus for Ethernet service delivery solves the most serious technical issues such as latency, jitter and network timing. Additionally, using the Ceterus equipment ensures carriers can minimize leased access lines, enable new services and maximize existing network assets thereby offering a tremendous business benefit.

“Ceterus Networks has made traction with the large carriers in both cell site backhaul and Ethernet delivery to enterprises, two issues facing wireless and wireline carriers," said Daniel Docter, senior investment manager, Intel Capital. "This investment aligns with Intel's strategic goals and supports the proliferation of new data delivery technologies, such as WiMAX.”

“We are very pleased to have Intel Capital and Aldus Equity join our long standing investors Sevin Rosen and ComVentures,” said David Stehlin, President and CEO of Ceterus. “Intel Capital brings a deep commitment to the expansion of data services in both the wireless and wireline markets and will offer great strategic value. Ceterus prides itself on offering carriers the highest quality next generation transport solutions which can be deployed with today’s networks. Our talented team has worked extremely hard to reach this point and we are all very excited about this next rapid growth stage and will continue to exceed the demands of both our investors and customers.”
