These products are used to protect the Trunk ports of PBX Systems or any telecom related products against high voltages hitting the telephone lines due to lightning, electrical inductions, etc.
The telephone lines should be connected to the input of these devices and the outputs of this device should be connected to the Trunk port of the PBX Systems or to any telecom related products that needs to be protected. When a high voltage strikes the telephone line, the circuit inside this product will operate and causes the glass fuses inside this device to blow off. This results in the input voltage to be isolated from the output port of this device and therefore the Trunk port of the PBX System or the telecom product that is connected at the output of this device to be protected. The input voltage to that port of this device will reach the output port of this device only after the blown off glass fuses inside this device are replaced manually.
The main components in these devices are Gas Discharge Tubes (GD Tubes) and Glass Fuses.
The input connectors and output connectors of these devices are RJ11 connectors.
These devices have LED indications for every port of these devices. The LED of each port will be ON only if the input telephone line and the 2 glass fuses inside this device for that port are working. If the telephone line connected to a port is not working, then the LED for that port will be OFF. If the telephone line connected to a port of this device is working, but If any one of the 2 glass fuses inside this device for that port is not working, then the LED for that port will be OFF.
1 LINE - EX-CALIBUR TELEPHONE LINE PROTECTION UNITS WITH LED INDICATIONS will have 1 input port , 1 output port, 1 LED and both the input and output connectors are RJ11 connectors. This is used to protect 1 Trunk port of any PBX System or any telecom related product.
