1.5.2 Setting Parameters for an FXO Interface

This section describes how to set parameters for an FXO interface.
Applicable Environment
An FXO interface connects to a PSTN. To achieve high transmission efficiency on an FXO
interface, properly set parameters for the FXO interface on the AR1200, including the gain,
impedance, ring current, and feed.
Pre-configuration Tasks
Before setting parameters for an FXO interface, complete the following task:
l
Data Preparation
