PMG5317-T20A is a GPON ONT that provides high-speed fiber access combines with residential gateway, VoIP and wireless features. It is compatible for optical ITU-T G.984 and wireless IEEE 802.11n environment.



Integrated Internet services through fiber optics

The Zyxel PMG5317-T20A Wireless N GPON HGU with a 4-port GbE Switch provides various integrated services through a single optical fiber for customers to support prevalent deployments of triple-play services such as data, video/highdefinition television (HDTV), VoIP and interactive games.




2.4 GHz 11n (2×2) for superior performance and coverage

The Zyxel PMG5317-T20A features 802.11n technology to provide an ultimate solution for both speed and coverage. With 802.11n wireless data rates of up to 300 Mbps, the PMG5317-T20A provides stable, reliable wireless connections for highspeed data and multimedia applications. The 802.11n technology empowers the device to eliminate dead zones and to extend coverage while retaining backward compatibility with any IEEE 802.11 b/g/n Wi-Fi certified device.

Advanced Quality of Service ensures quality of triple-play services

As higher bandwidth and greater efficiency of Ethernet cannot ensure effective delivery of high-quality voice, data and video across a GPON network, service providers can freely design their Quality of Service (QoS) policies and prioritize mission-critical services such as IPTV and VoIP based on their service plan offerings. This increases network efficiency and productivity to enable service providers to offer a real multi-play solution that meets the needs of residential users.


Provisioning and management through TR-069 along with OMCI

The Zyxel PMG5317-T20A can be connected to a GPON OLT to provide network operators with management and provision functions that support ONT Management and Control Interface (OMCI) as well as TR069 management functions. As a result, the operation and maintenance of the PMG5317-T20A are extremely easy and efficient.
