MDN. Mobile Directory Number. The directory listing telephone number that is dialed (generally using POTS) to reach
a mobile unit. The MDN is usually associated with a MIN in a cellular telephone -- in the US and Canada, the MDN
and MIN are the same value for voice cellular users. International roaming considerations often result in the MDN
being different from the MIN.
MIL. 1 mil = 1 thousandth of an inch.
MIN. Mobile Identification Number. The unique account number associated with a cellular device. It is broadcast by the
cellular device when accessing the cellular system.
Misread (Misdecode). A condition which occurs when the data output of a reader or interface controller does not agree

Mobile Computer. In this text, mobile computer refers to the Symbol Series 9000 wireless portable computer. It can be
set up to run as a stand-alone device, or it can be set up to communicate with a network, using wireless radio
technology.
N
Nominal. The exact (or ideal) intended value for a specified parameter. Tolerances are specified as positive and

(e.g., from 0.80 to 2.00 of nominal).
NVM. Non-Volatile Memory.
O
ODI. See Open Data-Link Interface.
Open Data-Link Interface (ODI). Novell’s driver specification for an interface between network hardware and
higher-level protocols. It supports multiple protocols on a single NIC (Network Interface Controller). It is capable of
understanding and translating any network information or request sent by any other ODI-compatible protocol into
something a NetWare client can understand and process.
Open System Authentication. Open System authentication is a null authentication algorithm.
P
PAN . Personal area network. Using Bluetooth wireless technology, PANs enable devices to communicate wirelessly.
Generally, a wireless PAN consists of a dynamic group of less than 255 devices that communicate within about a
33-foot range. Only devices within this limited area typically participate in the network.
