Quik-Call II (QCII)

Quik-Call II (QCII) is a "Non-ASTRO" signaling protocol that is used by specifically defined  Conventional Systems, and therefore for specifically defined Conventional channels. QCII is a sequential tone protocol normally associated with portable radios and pagers where the decoding of specific tone sequences sent from a radio or dispatch center allows individual radios, or groups of radios, to receive messages (Call Alerts or Selective Calls) intended only for them.
