Local Control . An optional mobile station feature used to perform manufacturer-specific functions.
A PN sequence with period 242-1 that is used for scrambling on the Forward CDMA Channel and spreading on the
Reverse CDMA Channel. The long code uniquely identifies a mobile station on both the Reverse Traffic Channel and
the Forward Traffic Channel. The long code provides limited privacy. The long code also separates multiple Access
Channels on the same CDMA channel. See also Public Long Code and Private Long Code.
Long Code Mask . A 42-bit binary number that creates the unique identity of the long code. See also Public Long
Code, Private Long Code, Public Long Code Mask, and Private Long Code Mask.
LSB. Least significant bit.
Maximal Length Sequence (m-Sequence). A binary sequence of period 2n-1, n a positive integer, with no internal
periodicities. A maximal length sequence can be generated by a tapped n-bit shift register with linear feedback.
Mcps. Megachips per second (106 chips per second).
Mean Input Power. The total received calorimetric power measured in a specified bandwidth at the antenna
connector, including all internal and external signal and noise sources.
Mean Output Power. The total transmitted calorimetric power measured in a specified bandwidth at the 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.(106 Hertz)
MIN . See Mobile Station Identification Number.
Mobile Protocol Capability Indicator (MPCI). A 2-bit field used to indicate 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)
