CHAPTER 1
Introducing the P-2812HNU-51c
1.1 Overview
The P-2812HNU-51c is a VDSL2 Integrated Access Device (IAD) that combines a
VDSL2+ router with Voice over IP (VoIP) communication capabilities. You may
access the Internet in one of these ways:
• You can have super-fast, secure Internet access over analog (POTS) telephone
lines. The P-2812HNU-51c supports both Packet Transfer Mode (PTM) and
Asynchronous Transfer Mode (ATM) and can be backward compatible with ADSL,
ADSL2 and ADSL2+.
• You can use an Ethernet WAN port for Internet access through the Ethernet
WAN connection.
• You can use 3G as your WAN and access the Internet via a 3G network.
The P-2812HNU-51c also allows you to use a traditional analog telephone to make
Internet calls. You can use Quality of Service (QoS) to efficiently manage traffic on
your network by giving priority to certain types of traffic and/or to particular
computers.
Please refer to the following description of the product name format.
• “H” denotes an integrated 4-port hub (switch).
• “N” denotes IEEE 802.11n wireless functionality. There is an embedded mini-PCI
module for IEEE 802.11b/g/n wireless LAN connectivity.
• “U” denotes a USB port used to set up a 3G WAN connection via a 3G wireless
card or share files via a USB memory stick or a USB hard drive. The P-
2812HNU-51c can also function as a print server with an USB printer connected.
Only use firmware for your P-2812HNU-51c’s specific model. Refer
