4.7.2 Telephone Line Port/ Subscriber Premises Protection
Figure 10: Primary Telephone Line Transient Protection
The telephone line surge protector is designed to be used as a primary station
protector at the subscriber end of the loop. It provides protection against lightning
surges, power cross conditions, and ground potential rises.
The protector element for each line consists of a heavy duty rated, (2) element
gas tube, an external backup gap assembly and a unique switch grade shorting
mechanism. The enclosure accommodates two protectors.
Two gas tubes are sealed in a fire resistant plastic body with plated #10 brass
studs, washers and hex nuts for connection to (2) subscriber pairs. A plated
brass ground connector is slotted to fit the ground connection points of station
protector housings and network interface devices. It has sectionalized grommet
in base for wire entry.
