FXS Ports

6.1

Introduction

This chapter provides connector pinout, configuration, and troubleshooting information for
the Foreign Exchange - Station (FXS) Voice port. This port is labeled Voice. See Appendix C
for pinouts of this connector.

This port manages the flow of FXS voice traffic over the network. Each port encodes analog
(voice, VF) signals to a digital bitstream at the local system for transmission over a T1
network. It also decodes the digital signals to analog at the remote system.

Each of the four FXS ports have two-wire interfaces that support FXS and PLAR. FXS allows
users to connect the system to a two-way (both inbound and outbound calls) PBX trunk or a
key system trunk. All the ports are pre-set to use the loop-start function with POTS stations
and simple PBX trunks.
