AES
Advanced Encryption Standard. An over-the-air link option that
provides extremely secure wireless connections. AES uses 128-bit
secret keys as directed by the government of the U.S.A. AES is not
exportable and requires a special AP to process the large keys.
AP
Access Point Module. One module that distributes network or Internet
services in a 60° sector to 200 subscribers or fewer.
APA
Access Point module address.
Apache
A trademark of Apache Software Foundation, used with permission.
APAS
Status page indication that confirms that authentication is active for the
AP. However, this indication does not confirm that authentication is
enabled (turned on) for the AP. See also Activate and Enable.
APs MIB
Management Information Base file that defines objects that are
specific to the Access Point Module or Backhaul timing master. See
also Management Information Base.
ARP
Address Resolution Protocol. A protocol defined in RFC 826 to allow a
network element to correlate a host IP address to the Ethernet
address of the host. See http://www.faqs.org/rfcs/rfc826.html
.
ASN.1
Abstract Syntax Notation One language. The format of the text files
that compose the Management Information Base.
Attenuation
Reduction of signal strength caused by the travel from the transmitter
to the receiver, and caused by any object between. In the absence of
objects between, a signal that has a short wavelength experiences a
high degree of attenuation nevertheless.
Authentication Key
Software key that correlates to the random number that the Bandwidth
and Authentication Manager (BAM) server generates and sends in a
challenge through the AP to the SM. The network operator can create
and, at some security risk, send this key over the air to the SM. The
SQL database in the BAM server correlates this key to QoS
information about the SM. The format of this key is 32 hexadecimal
characters of 0 to 9 and a to f, padded with leading zeroes in Release
4.2.3 and later releases. This key must be unique to the individual SM.
Authorization Key Field
Name of the parameter that identifies the authentication key in the SM
Configuration web page. See Authentication Key or skey.
Backhaul Module
Also known as BH. A module that provides point-to-point connectivity
as either a standalone link or a link to an Access Point cluster through
a selected Access Point Module. See also Backhaul Timing Master
and Backhaul Timing Slave.
Backhaul Timing
Master
Backhaul Module that sends network timing (synchronization) to
another Backhaul Module, which serves as the Backhaul timing slave.
