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.
Neighbor Set . The set of pilots associated with the CDMA Channel that are probable candidates for handoff.
Normally, the Neighbor Set consists of the pilots associated with CDMA Channel that cover geographical areas near
the mobile station. See also Active Set, Candidate Set, and Remaining Set.
A network is a subset of a Cellular system, such as an area-wide Cellular network, a private group of base stations, or
a group of base stations set up to handle a special requirement. A network can be as small or as large as needed, as
long as it is fully contained within a system. See also System.
Network Identification (NID). A number that uniquely identifies a network within a Cellular system. See also
System Identification.
NID. See Network Identification.
Non-Autonomous Registration. A registration method in which the base station initiates registration. See also
Autonomous Registration.
Non-Slotted Mode. An operation mode of the mobile station in which the mobile station continuously monitors the
Paging Channel when in the Mobile Station Idle State.
Ns. Nanosecond.
NULL . Not having any value.
Null Traffic Channel Data . One or more frames of 16 ‘1’s followed by eight ‘0’s sent at the 1200bps rate. Null
Traffic Channel data is sent when no service option is active and no signaling message is being sent. Null Traffic
Channel data serves to maintain the connectivity between the mobile station and the base station.
Number Assignment Module (NAM). A set of MIN-related parameters stored in the mobile station.
Numeric Information. Numeric information consists of parameters that appear as numeric fields in message
exchanged by the base station and the mobile station and information used to describe the operation of the mobile
station.
OLC. See Overload Class (CDMA) or Overload Control (analog).
Optional Field . A field defined within a message structure that is optionally to the message recipient.
Order. A type of message that contains control codes for either the mobile station or the base station.
