The EchoLife HG8242 is an indoor optical network terminal (ONT) in Huawei FTTH solution. By using the GPON technology, ultra-broadband access is provided for home and SOHO users. The HG8242 provides two POTS ports, four GE/FE auto-adapting Ethernet ports and one CATV port. The HG8242 features highperformance forwarding capabilities to ensure excellent experience with VoIP, Internet and HD video services. Therefore, the HG8242 provides a perfect terminal solution and future-oriented service supporting capabilities for FTTH deployment.

• 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, and call emulation initiated by the NMS.
• Link monitoring: E2E link detection is achieved using 802.1ag Ethernet OAM.
• High speed forwarding: GE line rate forwarding.
• 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.
