DragonWave introduced a Service Delivery Unit (SDU) product for enabling carriers to converge Time Division Multiplexing (TDM) and IP services over its wireless Ethernet network foundation.
The new SDU pseudowire solution provides both pseudowire and Ethernet switching functionality. The company will offer three versions of the SDU: a 16-port T1/E1 version, a two-port DS3 version and a one-port OC3/STM1 version. In addition to supporting point-to-point TDM transport, the SDU can provide virtual aggregation, further cutting carrier costs by reducing the requirement for TDM cross-connects in the network; a carrier could deploy the T1/E1 version of the SDU at multiple remote locations and aggregate the traffic with the DS3/OC3 version for delivery into the network core. The DragonWave solution supports up to six Gigabit Ethernet ports, in addition to the TDM ports. The SDU provides key carrier-grade features, such as traffic prioritization, Virtual Local Area Network (VLAN) tagging, Ethernet demarcation and full redundancy. Up to three SDUs can be deployed in a single standard carrier equipment rack unit.http://www.dragonwaveinc.com
