4FXS Foreign Exchange Station Trunk Module Loop Closure Detection

4FXS (Foreign Exchange Station) Telephony Trunk Interface Module

FXS is an interface that connects to a station, such as an analog telephone or the FXO interface of another PBX. It provides ringing voltage and battery to the FXO devices. FXS interfaces are used on the inside of your PBX, they do not connect directly to the PSTN. One FXS channel is required for each telephone that you wish to connect to your Asterisk system.

The Analog Station FXS board provides connectivity to standard analog phones. Typically, a phone is connected to a station interface and is, by default, in an on-hook state. When the phone goes off-hook, the phone completes the line circuit, and current flows through the line.
The Analog Station Interface provides the following features:

Ring Generation and Ringing Trip
Loop Closure Detection
Loop Disconnect
Loop Reversal
Loop Voltage and Current Monitoring
On-hook and Off-hook Transmission
Hook-flash Detection
DTMF Signalling
Programmable Audio Gain
On-board Power Generation
Constant Loop Current: 20mA
