NAM 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 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 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 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 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).
P-REV P-REV is the CDMA revision of the mobile or base station.
PDU 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.
PN Offset PN Offset stands for Pseudorandom Noise Offset. In a CDMA network the PN offset is a
variable time delay offset of a repeating random noise generator that is used to distinguish
individual sectors of a base station.
PRI PRI stands for Provisioning Information. Provisioning Information is your wireless network
carrier’s profile of information that must be programmed into your wireless modem in order
for it to operate on the carrier’s wireless network.
PRL PRL stands for Preferred Roaming List. The Roaming List is provided by the wireless
network carrier during the process of provisioning your module. The PRL is a list of
wireless service provider’s preferred roaming partners.
PSTN PSTN stands for Public Switching Telephone Network. It is the traditional telephone
network.
RF RF stands for Radio Frequency.
RSSI RSSI stands for Receive Signal Strength Indicator: This parameter represents the total RF
received signal power from the base station(s) the mobile sees.
R-UIM R-UIM stands for Removable User Identity Module. The R-UIM is similar to a SIM
(Subscriber Identity Module), but it is designed for networks other than GSM (Global
System for Mobile Telecommunications); i.e., networks such as CDMA.
The R-UIM card contains user information and data features on a removable smart card
about the size of a postage stamp. It is a dual-mode solution that can store both GSM
provisioning and CDMA provisioning on a single card. When used with a GSM handset,
the R-UIM operates like a GSM SIM.
SID SID stands for System ID. The SID is an identification number that represents geographic
locations of a common coverage area, usually a large city. Also see NID.
SIM SIM stands for Subscriber Identity Module. A SIM card is a portable memory chip. The
SIM holds personal identity information, cell phone number, phone book, text messages
and other data.
SMS SMS stands for Short Messaging Service. it is a supplementart service that is capable of
sending and receiving short length text messages to/from the mobile.
TA/TE TA/TE stands for Terminal Application/Terminal Equipment. This is the end “device”
(combination of hardware and software) that communicates with a modem via a serial link.
In this context, it is the device (PDA/Computer) connected to the WISMO Quik. Also see
DTE.
