Plug-and-play (PnP): Internet, IPTV and VoIP services can be deployed by one click on the NMS and on-site configuration is not required.
Remote diagnosis: Remote fault locating is implemented by the loop-line test of POTS ports, call emulation and PPPoE dialup emulation initiated by the NMS.
Link monitoring: E2E link detection is achieved using 802.1ag Ethernet OAM.
High speed forwarding: GE line rate forwarding in the bridge scenario and 900 Mbit/s forwarding in the NAT scenario.
Green energy-saving: 25% power consumption is saved with highly integrated system on chipset (SOC) solution, in which, a single chip integrates with PON, voice, gateway and LSW modules.
