G.SHDSL Module Port Setup

This chapter explains how to configure individual ports on the SAM1008.

12.1G.SHDSL Module Port Setup Overview

The web configurator allows you to configure settings for the G.SHDSL Access Module’s ports.

12.2G.SHDSL Standards Overview

The G.SHDSL module supports both the Annex A and the Annex B power spectral density regions with G.991.2.

12.3G.SHDSL Profiles

A profile is a table that contains a list of pre-configured G.SHDSL settings. Each G.SHDSL port has one (and only one) profile assigned to it at any given time. You can configure multiple profiles, including profiles for troubleshooting.

Profiles allow you to configure G.SHDSL ports efficiently. You can configure all of the G.SHDSL ports with the same profile by modifying the profile, thus removing the need to configure the G.SHDSL ports one-by-one. You can also change an individual G.SHDSL port by assigning it a different profile.

For example, you could set up different profiles for different kinds of accounts (for example, economy, standard and premium). Assign the appropriate profile to a G.SHDSL port and it takes care of a large part of the port’s configuration. See later in this chapter for how to configure profiles. You can only delete a profile when no G.SHDSL port refers to it.

12.4N-wire Mode

The n-wire mode allows you to physically bundle two G.SHDSL ports into a single 4-wire connection. The 4-wire mode is described in ITU-T G.991.2. You can use it to connect to G.SHDSL modems or routers that also support 4-wire mode. N-wire mode also allows you to physically bundle four G.SHDSL ports into a single 8-wire connection. The 8-wire group is proprietary and should be used between two SAM1008s.

N-wire mode can increase the reach of a particular data rate without having to regenerate the signal. It can also give increased bandwidth for LAN-to-LAN applications.
