ZYCOO 2FXOS U50-U100 2FXOS module with 2FXO and 2FXS interface 2FXOS (Foreign Exchange Office & Foreign Exchange Station)
ZYCOO 2FXOS U50-U100 2FXOS module with 2FXO and 2FXS interface is mixed interface of foreign exchange office and foreign exchange station that connect to office and station. It includes 2FXO ports and 2FXS ports, and can be combined with BRI, PRI, GSM module.FXO interfaces are used to connect your PBX to the PSTN. One FXO channel is required for each line you receive from your telco.
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 Interface(FXO) provides the following features:
•Ring Generation and Ringing T rip
•Loop Closure Detection
•Loop Voltage and Current Monitoring
•On-hook and Off-hook T ransmission
•Programmable Audio Gain
•On-board Power Generation
•Constant Loop Current: 20mA
The loop start Analog Interface(FXS) provides the following features:
•Detects ringing when on-hook
•Detects loop current when off-hook
•Detects when tip/ring voltage crosses a set voltage when on-hook or off-hook (called DC
•Can accommodate private branch exchange (PBX) with –48 V battery voltage
•Loop current range: 13-110mA
•Voltage detection threshold is software-selectableThe 2FXOS module supports CooVox-U50/ CooVox-U100 IP Phone System with 4 RJ11 ports for connection. Each port has one
LED(Light-Emitting Diode), which is assembled on the main board.
FXS—Green LED indicates port status:
>Solid Green= Module loading successful
>Blink Green= Ringing
FXO—Red LED indicates port status:
>Solid Red= Module loading successful
>Blink Red= Ringing
If the LED is off , the module is loading failure.
All four ports on Zycoo 2FXOS module bracket are 6P4C RJ11 ports. The pin assignments are indentified in T abel 1.

Environmental Operation Information
Temperature: 0°C ~ 40°C
Humidity: 5% ~ 95% Non-Condensing
Long term operation of FXS will cause some malfuncti on and affect the system reliability; to avoid any malfunction and assure
reliable, the FXS module forced- air cooling is mandatory.
