# TowerNET Series
Siecor Network Interface
Line Module


The NET Series is a SIECOR Network Interface Line Module with built-in secondary surge protection. In addition to silicon breakover clamping technology (overvoltage), the NET Series incorporates state-of-the-art resettable overcurrent protection devices—PTCs. The overcurrent circuitry allows normal telephone currents to pass, but quickly switches to a high impedance state when subjected to extended overcurrents that can damage telephone system line cards.

FEATURES
• Tip to Ring Protection
• Tip, Ring to Ground Protection
• Clamping Does Not Degrade with Age
• Solid-State Overcurrent Protection
• UL 497A Listed
• Resettable Fusing—PTCs
