Advanced Encryption Standard
Digital Automated Communications Terminal
Dynamic Host Configuration Protocol, which provides a mechanism for
allocating IP addresses dynamically so that addresses can be reused
when hosts no longer need them.
Domain Name System, which is a distributed hierarchical naming
system used to resolve domain names (e.g., www.yahoo.com) into
numerical IP addresses (e.g., 18.104.22.168.).
Digital Subscriber Line.
Enhanced Console Protocol, which is a proprietary bus used in Honeywell
control panels to communicate with keypads and peripheral devices. It
uses four wires; power, ground, data in, data out.
A gateway (sometimes called a router) is a computer and/or software
used to connect two or more networks (including incompatible networks)
and translates information from one network to the other. The Gateway
IP address is the IP address for the gateway.
General Packet Radio Service.
Global System for Mobile communications, which is an international
standard for digital mobile phone systems used for cellular
International Mobile Equipment Identity number.
A unique number consisting of four parts separated by periods (for
example: 22.214.171.124). An IP Address can be fixed or "static", or
"dynamic," where the IP Address is assigned via DHCP at every startup.
Integrated Services Digital Network.
Internet Service Provider.
Local Area Network.
Media Access Code, this is a unique address assigned to every network
communications device. For the communications module it is located on
the module label, and on the box.
A Subnet is a portion of a network that shares a network address with
other portions of the network, and is distinguished by a subnet number.
The Subnet Mask is a 32-bit address mask used in IP to indicate the bits
of an IP address that are being used for the subnet address.
Transmission Control Protocol / Internet protocol.
