ZYCOO 4FXO U50 U100 4 FXO module with interface 4 FXO Mtech Network
ZYCOO 4FXO U50 U100 4 FXO module with interface 4 FXO provides connectivity to analog central office loop start trunk line analog interfaces. And it can be combined with BRI, PRI, GSM module.
Typically, a phone is connected to a loop start line from the Telco 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 FXO Analog Interface provides the following features:
- Detects ringing when on-hook
- Detects loop current when off-hook
- DC triggering
- Can accommodate private branch exchange (PBX) with -48 V battery voltage
- Loop current range: 13-110mA
- Voltage detection threshold is software-selectable
