AES – Advanced Encryption Standard
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 communications bus used in
Honeywell VISTA control panels for wiring additional keypads and peripheral devices;
consists of a four-wire data bus (power+/-, data in/out).
Gateway IP Address - A gateway (sometimes called a router) is a computer and/or software

"dynamic," assigned via DHCP at each and every startup.
ISDN – Integrated Services Digital Network

LAN – Local Area Network
MAC Address – Media Access Code; located on the module label.
PPPoE – Point-to-Point Protocol over Ethernet
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
