antenna connector when the transmitter is active.
Message. A data structure that conveys control information or application information. A message consists of a
length field (MSG_LENGTH), a message body (the part conveying the information), and a CRC.
Message Body. The part of the message contained between the length field (MSG_LENGTH) and the CRC
field.
Message Capsule. A sequence of bits comprising a single message and padding. The padding always follows
the message and may be of zero length.
Message CRC. The CRC associated with a message. See also Cyclic Redundancy Check.
Message Field. A basic named element in a message. A message field may consist of zero or more bits.
Message Record. An entry in a message consisting of one or more field that repeats in the message.
MHz. Megahertz.(10 6
Herz)
MIN. See Mobile Station Identification Number.
Mobile Protocol Capability Indicator (MPCI). A 2-bit field used to indicate 속 mobile station's capabilities.
Mobile Station. A station in the Domestic Public Cellular Radio Telecommunications Service intended to be
used while in motion or during halts at unspecified points. Mobile station include portable units (e.g., handheld
personal units) and units installed in vehicles.
Mobile Station Class. Mobile station classes define mobile station characteristics such as slotted operation and
transmission power.
Mobile Station Identification Number (MIN). The 34-bit number that is a digital representation of the 10-digit
directory telephone number assigned to a mobile station.
Mobile Station Originated Call. A call originating from a mobile station.
Mobile Station Terminated Call. A call received by a mobile station (not to be confused with a disconnect or
call release).
Mobile Switching Center (MSC). A configuration of equipment that provides cellular radiotelephone service.
Also called the Mobile Telephone Switching Office (MTSO)
Modulation Symbol. The output of the data modulator before spreading. On the Reverse Traffic Channel,
64-ary orthogonal modulation is used and six code symbol (when the data rate is 9600bps) or each repeated code
symbol (when the data rate is less than 9600bps) is one modulation symbol.
Ms. Millisecond.
MSB. Most significant bit.
MSC. See Mobile Switching Center.
Multiplex Option. The ability of the multiplex sublayer and lower layer to be tailored to provide special
capabilities. A multiplex option defines such characteristics as the frame format and the rate decision rules. See
also Multiplex Sublayer.
Multiplex Sublayer. One of the conceptual layers of the system that multiplexes and demultiplexes primary
traffic, secondary traffic, and signaling traffic.
NAM. See Number Assignment Module.
Narrow Analog. A type of voice channel that uses 10kHz channel spacing and subaudible signaling.
