  • Abstract
    THE BELL SYSTEM´s new N1 carrier system is a low-level cable carrier system providing 12 4-wire telephone channels in the frequency range of 44 to 260 kc. Because of its low levels, the N1 system is particularly susceptible to interference from other existing carrier systems with over lapping frequencies and higher energy levels.
