VX8350
Discontinuous Transmission (DTX). A mode of operation in which a mobile station transmitter autonomously
switches between two transmitter power levels while the mobile station is in the conversation state on an analog voice
channel.
Distance-Based Registration. An autonomous registration method in which the mobile station registers whenever it
enters a cell whose distance from the cell in which the mobile station last registered exceeds a given threshold.
DTMF. See Dual Tone Multifrequency.
Dual-Tone Multifrequency (DTMF). Signaling by the simultaneous transmission of two tones, one from a group of
low frequencies and another from a group of high frequencies. Each group of frequencies consists of four frequencies.
Eb. The energy of an information bit.
Ec/I0. The ratio in (dB) between the pilot energy accumulated over one PN chip period (Ec) to the power spectral
density in the received bandwidth (Io).
Effective Radiated Power (ERP). The transmitted power multiplied by the antenna gain referenced to a half wave
dipole.
Electronic Serial Number (ESN). A 32-bit number assigned by the mobile station manufacturer, uniquely
identifying the mobile station equipment.
Encoder Tail Bits. A fixed sequence of bits added to the end of a block of data to reset the convolutional encoder to
a known state.
ERP. See Effective Radiated Power.
ESN. See Electronic Serial Number.
Extended Protocol. An optional expansion of the signaling message between the base station and mobile station to
allow for the addition of new system features and operational capabilities.
Fade Timer. A timer kept by the mobile station as a measure of Forward Traffic Channel continuity. If the Fade
timer expires, the mobile station drops the call.
Flash. An indication sent on an analog voice channel or CDMA Traffic Channel indicating that the user Directed the
mobile station to invoke special processing.
Foreign NID Roamer. A mobile station operating in the same system (SID) but a different network (NID)Form the
one in which service was subscribed. See also Foreign SID Roamer and Roamer.
Foreign SID Roamer. A mobile station operating in a system (SID) other than the one from which service was
subscribed. See also Foreign NID Roamer and Roamer.
Forward Analog Control Channel (FOCC). An analog voice channel used from a base station to a mobile station.
Forward Analog Voice Channel (FVC). An analog voice channel used from a base station to a mobile station.
Forward CDMA Channel. A CDMA Channel form a base station to mobile stations. The Forward CDMA Channel
contains one or more code channels that are transmitted on a CDMA frequency assignment using a Particular pilot
PN offset. The code channels are associated with the Pilot Channel, Sync Channel, Paging Channels, and Traffic
Channels. The Forward CDMA Channel always carries a Pilot Channel and may carry up to one Sync Channel, up to
seven Paging Channels, and up to 63 Traffic Channels, as long as the total number of channels, including the Pilot
Channel, is no greater than 64.
