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 SocketModem. 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 SocketModem. The R-UIM is similar to a SIM
(Subscriber Identity SocketModem), 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 SocketModem. 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 supplementary 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.
