The OFCN Telephone Line Network Cable Tester Tool Set (Model C019) is designed for efficient telephone line fault diagnosis. This tool connects directly to the phone line, eliminating the need for batteries. It offers essential functions like last number redial, on/off, and hangup buttons, crucial for troubleshooting. The integrated FSK/DTMF dual system Caller ID allows for incoming call information display, provided the local telephone office service is active.
Usage is straightforward: connect one end of the line to the tester and the appropriate line plug. When the phone rings and Caller ID service is enabled, the display shows the caller's number. The 'on/off' button functions as a hangup. For dialing, press 'on/off' after hearing a dial tone. If a busy tone is encountered, the 'receiving line' button can be used to automatically receive the line. After a call, press 'open/close' to end the connection.
This tester comes equipped with three distinct exterior line plugs, allowing you to choose the best fit for your specific connection needs. Its compact design and battery-free operation make it a practical and reliable tool for any technician working with standard telephone lines in India.
