1.1.1 High-speed Internet Access with G.SHDSL
The P-79X provides high-speed G.SHDSL Internet access. The G.SHDSL (Single-pair High-speed
Digital Subscriber Line) is a symmetrical, bi-directional DSL service that uses your telephone line to
provide data rates up to 2.3 Mbits/sec. (The “G.” in “G.SHDSL” is defined by the G.991.2 ITU
(International Telecommunication Union) state-of-the-art industry standard). Unlike ADSL or
VDSL, G.SHDSL.bis supports the same high speed for transmission and receiving.

For Internet access, connect the DSL port to the phone port. Then, connect your computers or
servers to the LAN ports for shared Internet access. (See the Quick Start Guide for detailed
instructions about hardware connections.) Next, set up the P-79X as a router or as a bridge,
depending on the desired configuration.
1.1.2 High-speed Point-to-point Connections
You can use another P-79X or any SHDSL device with the P-79X to create a cost-effective, high-
speed connection for high-bandwidth applications such as videoconferencing and distance learning.

The P-79Xs provide a simple, fast point-to-point connection between two geographically-dispersed
networks.
1.1.3 High-speed Point-to-2points Connections
Use three P-79Xs or 2 SHDSL devices with the P-79X to connect two remote networks to a central
location. For example, connect the headquarters to two branch offices. In this scenario the central
P-79X acts in a similar way as an Internet service provider.
