Features ■ ■ Meets the T1 pulse mask as per ANSI T1.403 and the E1 mask per ITU G.703 The protectors utilize PTC resistor technology for automatic resetting overcurrent protection and gas discharge tube technology for overvoltage protection ■ ■ ■ Both protectors can be on-site configured for either powered or unpowered spans Simplicity of DIN-3 rail mounting; the rail also serves as protector ground Vibration proof screw-type clamping connector interface 1830 T1/E1 Surge Protector The Model 1830 Surge Protectors are designed for use on T1 and E1 lines entering Customer Premises and Wireless Transmission Facilities. The 1830 provides Secondary Protection as per UL497A. The principal use is for protection of telephone equipment against direct and induced lightning surges, power-line disturbances and ground potential rises. One Protector is used for the transmit pair and a second Protector is for the receive pair.
