The Device is a VDSL2 gateway that allows super-fast, secure Internet access over
analog (POTS) telephone lines. It supports both Packet Transfer Mode (PTM) and
Asynchronous Transfer Mode (ATM). You can have multiple ADSL (ADSL, ADSL2,
ADSL2+) connections or multiple VDSL (VDSL, VDSL2) connections.
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 802.11n draft 2.0. The “N” models support 802.11n wireless
connection mode.
Only use firmware for your Device’s specific model. Refer to the
label on the bottom of your Device.
Models ending in “1”, for example P-870HN-51, denote a device that works over
the analog telephone system, POTS (Plain Old Telephone Service).
See
Chapter 28 on page 277
for a full list of features.
1.2

•
TR-069. This is an auto-configuration server used to remotely configure your
device.
1.3
Good Habits for Managing the Device
Do the following things regularly to make the Device more secure and to manage
the Device more effectively.
•
Change the password. Use a password that’s not easy to guess and that consists
of different types of characters, such as numbers and letters.
•
Write down the password and put it in a safe place.
•
Back up the configuration (and make sure you know how to restore it).
Restoring an earlier working configuration may be useful if the device becomes
unstable or even crashes. If you forget your password, you will have to reset the
Device to its factory default settings. If you backed up an earlier configuration
file, you would not have to totally re-configure the Device. You could simply
restore your last configuration.
1.4
Applications for the Device
Here are some example uses for which the Device is well suited.
1.4.1

Device’s Internet Access Application
You can also configure IP filtering on the Device for secure Internet access. When
the IP filter is on, all incoming traffic from the Internet to your network is blocked
by default unless it is initiated from your network. This means that probes from
the outside to your network are not allowed, but you can safely browse the
Internet and download files.
