Luminous Networks introduced new versions of its Packet Ring Access Platform for multi-service applications over Ethernet-based Metropolitan Area Networks (MANs). The new E100 Packet Ring Access Platform provides four fixed 10/100BaseT user interface ports and an additional slot for either four additional 10/100BaseT ports or one Gigabit Ethernet (GbE) port. A second configuration supports legacy T1/E1 and Ethernet services with four fixed T1/E1 user interface ports and, software selectable, either four 10/100BaseT ports or one GbE port.
On the network side, both models can be deployed in a Resilient Packet Ring (IEEE 802.17) topology supporting east and west facing 1 Gigabit ring interfaces, providing ring protection in less than 50ms. Alternatively, the E110 and E150 can be deployed in a linear topology for applications such as Multiple Tenant Unit (MTU). Both versions are interoperable with PacketWave M-Series, C-Series and other E-Series platforms. http://www.luminous.com
