Definition 1 of 111
To enable upstream transmissions, a cable modem must first send a ranging request (RNG-
REG) to the cable modem termination system (CMTS). The CMTS then sends a ranging
response (RNG-REG) to adjust the modems:
Timing, frequency, and transmit power level.
To guide the light down the fiber
The u.s. deficit reduction act.
Monitor transmission and signal distortions over a wide spectrum and troubleshoot data
carrier levels.
Definition 2 of 111

Analog signals are always faster than digital signals
Digital signals are not used in modern communication systems
Analog networks cannot transmit data over long distances
Digital networks can combine, or multiplex, several different signals into one
transmission
