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).

subnet address.
