General Application Notes

Highlights of P2812HNU-51c

The P-2812HNU-51c is a VDSL integrated access device (IAD), which provides
high-speed VDSL Internet access from major vendors to meet the worldwide market
requirements of triple-play services. The P-2812HNU-51c model also features built-in
802.11n WLAN which helps resolve some of those troublesome wirings. Two lines of
telephony service are provided using VoIP technology with SIP signaling protocol.
Additionally, it is designed with dual WAN function, suitable for xPON or WiMax
users. Users can also leverage the USB interface in P-2812HNU-51c for file sharing or
together with 3G USB dongle for 3G backup.

Dual WAN to Simplify the Logistics for ISP

When a customer migrates from ADSL2+ or VDSL2 to PON or WiMax, the ISP only
needs to send out a "dumb" and relatively cheap bridge-device terminating the
physical connection, and provide an Ethernet-interface towards the customer. The
customer' s existing CPE (P-2812HNU-51c) will still be used for terminating the
IP-connection but now via the Ethernet WAN-interface. The end-users can still
experience in most cases from the original CPE, which is better than the customer
having to change the CPE due to the difference of physical connection.

Internet Access through 3G Networks

The P-2812HNU-51c with USB interface for 3G USB dongle provides convenient
Internet access for 3G networks to eliminate limitations of wired networks and to
further extend the last-mile connectivity. In Internet-challenged environments such
as rural or mountain areas, 3G connectivity may be the only viable solution; and it
can be used to provide temporary Internet access to places such as exhibition booths
as well. Furthermore, 3G access can be used as a WAN backup for high-availability
Internet connection in office environments.

Dual mode VDSL2/ADSL2+ functionality

The P-2812HNU-51c Series support dual- mode functionality that enables service
providers to support ATM or PTM on the same device. It offers bi-directional high
speed VDSL2, VDSL connection with speed up to 100/45Mbps in PTM mode and
24/1Mbps ADSL2+, ADSL2, ADSL connection in ATM mode. This powerful feature
ensures the service provider can support the connection not only on the IP network
