Driver (Device)

the Enterprise Edge Server.

See Dual tone multifrequency.

dual tone multifrequency

Two distinct telephone signaling tones used for dialing.

Dynamic Host Configuration Protocol (DHCP)

DHCP isa protocol that lets network administrators centrally manage and automate

the assignment of IP addresses in an organization's network. Using the Internet's set

of protocols (TCP/IP), each machine that can connect to the Internet needs a unique

IP address. When an organization sets up its computer users with a connection to

the Internet, an IP address must be assigned to each machine.

Without DHCP, the IP address must be entered manually at each computer and, if

computersmove toanother locationin anotherpart ofthe network, a newIP address

must be entered. DHCP lets a network administrator supervise and distribute IP

addresses from a central point and automatically sends a new IP address when a

computer is plugged into a different place in the network.

dynamic IP address

A dynamic IP address changes. Dynamic IP addresses are assigned to computers by

an IP address server as the computer needs it. Usually there is a particular range, or

scope, of IP addresses that your network uses. With dynamic IP addressing, a

computer can have a different IP address every time it connects to the network.

Other devices must know the computer’s IP address so that they can communicate

with it. The IP address server manages the assignment of IP addresses to the client

workstations. See also static IP address.

Emergency 911 dialing

The capability to access a public emergency response system by dialing the digits

9-1-1. State and local requirements for support of Emergency 911 Dialing service

by Customer Premises Equipment vary. Consult your local telecommunications

service provider regarding compliance with applicable laws and regulations.

emergency telephone

A single-line telephone (also referred to as a 500/2500 telephone) that becomes

active when there is no power to the Enterprise Edge Server.
