The deal will give Cisco access to PipeLinks' Sonet/SDH router technology, which handles circuit traffic and IP traffic at the same time, enabling service providers to offer integrated voice and data services to the edge of a network.
The advent of its fatter version is opening up the transfer of WAN data from ATM, frame-relay or packet over SONET/SDH to a potentially more efficient and cheaper method. Even Andrew Rufener, ambassador to the ATM Forum and director of technology...
Namely, Resilient Packet Ring (RPR), which should solve the first problem and ITU x.86, which addresses the second. Nothing here, it would seem, to challenge the incumbent technologies, most notably Sonet/SDH (synchronous digital hierarchy), a...
The standards will be referenced by the telco standards body, the ITU (International Telecommunications Union) - in itself a very big indication of Ethernet's arrival in the telecoms area. Existing metro networks have used Sonet/SDH, an expensive...
This led the researchers to conclude that any physiological responses were unrelated to the signals. Using a group of 'sensitive' individuals (44 people) and a control group (114 people), the study found that, in double-blind conditions (where...
These factors have made it difficult to make exact measurements of energy emissions, the HPA said. The signals are very low power, typically 0.1 watt in both the computer and the router, and the results so far show exposures are well within...
