= 000100: Normal amplitude in T1 long haul LBO/-22.5 dB operating mode. Each step change scales about 25% offset.
= 001000: Normal amplitude in T1 long haul LBO/-15 dB operating mode. Each step change scales about 12.5% offset.
= 010001: Normal amplitude in T1 long haul LBO/-7.5 dB operating mode. Each step change scales about 6.25% offset.
= 110110: Normal amplitude in T1 0~133 ft, 133~266 ft, 266~399 ft, 399~533 ft, 533~655 ft, DS1 0 dB & J1 0~655 ft operating modes. Each step
