13.1 Introduction

This chapter provides installation, configuration, and troubleshooting information for the
Foreign Exchange - Office (FXO) Card, which is identified as a FXO 2W*8-6 card on its
faceplate ejector.
The FXO 2W*8-6 Card manages the flow of FXO voice traffic through the integrated access
system. Each card encodes analog (voice, VF) signals to a digital bitstream at the local system
for transmission over a T1 or E1 network. It also decodes the digital signals to analog at the
remote system.
The card has a two-wire interface and supports Foreign Exchange - Office (FXO), Manual
Ringdown (MRD), Foreign Exchange Office-Defined Network (FXODN), and Dial-Pulse
Terminating (DPT) operations.
The FXO card also can use the voice compression features of an ADPCM card.
