FXS Ports

6.1Introduction

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.
