IS-95 is the first CDMA standard published by Qualcomm in 1993. It is a TIA standard for
North American cellular systems based on CDMA. It is widely deployed in North America
and Asia.
IS-95A is a CDMA standard with improved voice quality. IS-95A defines what generally is
known as cdmaOne, which supports voice and 14.4 Kbps data rates. This standard is
widely used throughout the world.
IS-95B is a CDMA standard contains Medium Data Rate capabilities and bug fixes for
system access failures. It is considered a 2.5G system. It supports data rates up to 115
Kbps.
IS-2000 is the first 3G CDMA standard based on IS-95B. It contains a significant increase
in voice capacity and high-speed data rates. It is backward compatible with IS-95B and
IS-95A.
TIA/EIA/IS-707 describes data services available on wideband spread spectrum
systems. It is organized into a series of related recommendations, some of which address
functions common to all CDMA data services and others that describe a specific data
service.
Interworking Function. A process that acts as a gateway or interface between two or
more communication components. For example, an IWF is used to interface wireless
CDMA networks and wire line PSTN or packet-data networks.
Link Access Procedure for Modems. An error control protocol defined in the ITU-T
recommendations V.42. Like the MNP protocols, LAPM uses cyclic redundancy checking
(CRC) and retransmission of corrupted data (ARQ) to ensure data reliability.
Mobile Country Code is a pre-defined 30-digital number that represents a country in the
IMSI.
MDN stands for Mobile Data Number or the mobile phone number.
MIN stands for Mobile Identification Number or mobile user account number.
MNC stands for Mobile Network Code, a pre-defined 2-digital number that represents a
sub-network in the IMSI (usually set to “00”).
MO stands for Mobile Originated, an action (usually a call) that is first started from the
phone. An outgoing call or SMS.
MS stands for Mobile Station. The term MS is commonly used to represent the phone or
mobile.
MT stands for Mobile Terminated. MT is an action, usually a call that is first started from a
land based network. An incoming call or SMS.
MSM stands for Mobile Station Modem.
NAM stands for Number Assignment Modem. The NAM is collection of internal
parameters that define a working phone for a given network (phone number, access
parameters, etc.).
NID stands for Network ID. The NID is an identification number that represents
geographic location of a common coverage area; but is a subset of the SID, usually a
neighborhood in a large city. NID is usually not used and is set to zero. Also see SID.
NV-RAM stands for Non-Volatile Random Access Memory. NV-RAM is a data storage
device that does not lose its data when power is turned off.
OTAPA stands for Over The Air Parameter Administration. It is an automatic update in
internal software parameters (PRL for example) by means of a specially defined CDMA
data call that is mobile terminated (MT).
OTASP stands for Over The Air Service Programming. It is an automatic update in
internal software parameters PRL; for example, PRL by means of a specially defined
CDMA data call that is mobile terminated (MT).
Position Determination. Process by which the mobile GPS position is obtained.
PDU stands for Protocol Data Unit. It is a GSM SMS standard whereby any type of binary
data can be transported via an SMS message. In the CDMA system, the PDU mode will
not be supported; instead, the Unicode format message is supported.
