Numéricable has selected the Calix E7-2 Ethernet Service Access Platform and gigabit passive optical network technology to upgrade its service delivery platform in Belgium and Luxembourg. Calix, along with optical specialist Arcadiz Telecom, will work closely to roll out Numéricable’s new high-speed broadband networks to deliver business services across the region. The new platform will enable Numéricable’s customers to take advantage of advanced voice, video, and data services at symmetrical speeds ranging from 30 megabits per second (30 Mbps) up to 1 gigabit per second (1 Gbps).

Numéricable serves over 150,000 customers in Brussels with triple-play services for residential subscribers. Owned by Coditel and with a close relationship to the French Numéricable organization, with whom it shares a range of resources, Numéricable Belgium is a long-established operator with a highly dispersed coax cable network. The company has traditionally delivered triple-play residential services over its hybrid fiber coax infrastructure, but in recent years has moved increasingly towards using its fiber to connect businesses and has developed a number of specific niche markets. The company is now looking at ways to maximize the potential of its fiber infrastructure in Belgium and Luxembourg and deliver revenue-generating advanced services to its business customers.

A person needing a kidney transplant may have a friend or relative who volunteers to be a living donor, but whose kidney is incompatible, forcing the person to wait for a transplant from a deceased donor. In the U.S. alone, thousands of people die each year without ever finding a suitable kidney. A new technique applies graph theory to groups of incompatible patient-donor pairs to create the largest possible number of paired-donation exchanges. These exchanges, in which a donor paired with Patient A gives a kidney to Patient B while a donor paired with Patient B gives to Patient A, will dramatically increase transplants from living donors. Since transplantation is less expensive than dialysis, this mathematical algorithm, in addition to saving lives, will also save hundreds of millions of dollars annually. Naturally there can be more transplants if matches along longer patient-donor cycles are considered (e.g., A.s donor to B, B.s donor to C, and C.s donor to A). The problem is that the possible number of longer cycles grows so fast hundreds of millions of A >B>C>A matches in just 5000 donor-patient pairs that to search through all the possibilities is impossible. An ingenious use of random walks and integer programming now makes searching through all three-way matches feasible, even in a database large enough to include all incompatible patient-donor pairs.
