CONFIGURING DSL PARAMETERS

The DSL parameters set up the G.shdsl communication between the modem and a DSLAM or between two modems used in a point-to-point application. Typically, the DSL parameters for the modem are preset to immediately synchronize with the service provider (DSLAM application). However, you may be instructed to make changes to the DSL configuration. This chapter provides information for setting G.shdsl parameters when the modem is in an application as a DSLAM endpoint. For instruction on setting up G.shdsl parameters for a point-to- point modem application, go to Chapter 7: Implementing a Point-To-Point LAN Extension.

BEFORE YOU BEGIN

The following are configurable DSL parameters for the G.shdsl modem; change parameters only when instructed to do so by the service provider or your system administrator.

•The operating mode choices are Remote (use when the modem is an endpoint for a DSLAM application or the customer-side modem in a point-to-point application) or Central-Office (use only for the central office-side modem in a point-to-point application)

•Annex A or B provides the appropriate operating characteristics for G.shdsl, dependent on your geographical location.

•A margin value, in decibels, that must be met to initialize modem.

•Either fixed or adaptive mode that the modem will use to negotiate the best transmission rate at which both ends of the connection can synchronize.

•Wire pair mode: Single (two-wire), Dual (four-wire) or Dual-Enhanced can be selected only for the MM702G2 modem. The MM701G2 modem is used only in Single mode. Dual-Enhanced provides the Adaptive mode in four-wire operation.

•PSD mask is either symmetric or asymmetric. The values used to calculate the asymmetric mask are dependent on the Annex A or B you selected.
