ZYCOO 2FXOS U50-U100 2FXOS module with 2FXO and 2FXS interface is the 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 modules.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 Disconnect
•Loop Reversal
•Loop Voltage and Current Monitoring
•On-hook and Off-hook T ransmission
•Hook-flash Detection
•DTMF Signalling
•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
triggering)
•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
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.
