DHCP
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.
DNS
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., 204.17.25.1.).
DSL Digital Subscriber Line.
ECP
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.
Gateway IP

LRR
Long Range Radio, an older term now referred to as communicator. A
broader term communications module or communications device may also

MAC ID
Media Access Code, this is a unique address assigned to every network
communications device. This is located on the box, and inside the
communicator.
Subnet Mask
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.
TCP / IP Transmission Control Protocol / Internet protocol.
