The recently released members of the ETX family include the ETX-205A and new versions of the ETX-203A supporting unique features such as all-in-one capabilities. These products will be followed later in 2012 with 10G NTU and the ETX-5300 access aggregation platform for a complete solution for Ethernet access. Scale GE nxGE nx10GE

The ETX-36 as a small demarcation is suitable for office connectivity due to a small footprint and low power consumption (Max 5.5W) enabling the carrier to monitor and control the network starting at the customer premises (OAM and management capabilities) while providing advanced QoS using flows - prioritization of the traffic by classifying it to different flows and providing QoS per service type (Rate limitation, P-bit remarking, Vlan manipulation, shaping…).

Low cost CPE that enables monitor of the network edge, and handle the traffic management from the aggregation site where the congestion may happen Access using the ETX-5300A can be in ring or star topology. In future version we will support G.8032 in the ETX-36 and enable building multiple 1GbE access rings with the ETX-5300A as the core for these rings. Adding access aggregation layer allows to free up the expensive ports in a PE router while using RAD access aggregation.
