As opposed to regular ->PCM, asample is coded as the difference between its predicted value and its real value. As thisdifference is usually smaller than the real, absolute value itself, a lesser number of bits canbe used to encode it.CCSTAComputer Supported Telecommunications Applications. An abstraction layer for telecom-munications applications allowing for the interaction of ->CTI computer applications withtelephony devices and networks.CTIComputer Telephony Integration. This term denotes the interaction of computer applica-tions with telephony devices and networks.DDFTDigital Feature Telephone. A phone with no line keys.DHCPDynamic Host Configuration Protocol. Allows for the automatic configuration of networkendpoints, like IP Phones and IP Clients.DiffServDifferentiated Services. Specifies a layer 3 mechanism for classifying and managing net-work traffic and providing quality of service (->QoS) guarantees on ->IP networks.
