(BAM) master server in the database replication setup.
10 BaseT
Technology in Ethernet communications that can deliver 10 Mb of data
across 328 feet (100 meters) of CAT5 cable.
100 BaseT
Technology in Ethernet communications that can deliver 100 Mb of
data across 328 feet (100 meters) of CAT5 cable.
169.254.0.0
Gateway IP address default in Canopy modules.
169.254.1.1
IP address default in Canopy modules.
169.254.x.x
IP address default in Microsoft and Apple operating systems without a
DHCP (Dynamic Host Configuration Protocol) server.
255.255.0.0
Subnet mask default in Canopy modules and in Microsoft and Apple

802.3
An IEEE standard that defines the contents of frames that are
transferred through Ethernet connections. Each of these frames
contains a preamble, the address to which the frame is sent, the
address that sends the frame, the length of the data to expect, the
data, and a checksum to validate that no contents were lost.
Access Point Cluster
Two to six Access Point Modules that together distribute network or
Internet services to a community of 1,200 or fewer subscribers. Each
Access Point Module covers a 60° sector. This cluster covers as much
as 360°. Also known as AP cluster.
Access Point Module
Also known as AP. One module that distributes network or Internet
services in a 60° sector to 200 subscribers or fewer.
ACT/4
Second-from-left LED in the module. In the operating mode, this LED
is lit when data activity is present on the Ethernet link. In the aiming
mode for a Subscriber Module or a Backhaul timing slave, this LED is
part of a bar graph that indicates the quality of the RF link.
Activate
To provide feature capability to a module, but not to enable (turn on)
the feature in the module. See also Enable.
Address Resolution
Protocol
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
.
Advanced Encryption
Standard
Over-the-air link option that provides extremely secure wireless
connections. Advanced Encryption Standard (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.
