NADC/TDMA is a dual mode, full duplex cellular communications system in which each voice channel can be defined by both a frequency and a time slot.

On a mobile, this can be done by either pressing ‘END’ or by merely turning power off. When the mobile user terminates the call, the base station smoothly disconnects from the mobile.
  • Page 277 Basic Functions of the DCCH in TIA/EIA-136 Registration for TIA/EIA-136 differs under certain conditions.

  • Page 280 Basic Functions of the DCCH in TIA/EIA-136 Mobile Assisted Handoff (MAHO) MAHO is actually a set of measurements, not a handoff. The base station requires the mobile to provide RF channel signal quality information to its serving base station. The base can then choose a specific channel for the handoff. If the mobile provides information on the present RF channel, it sends RSSI and BER information.
