ADSL
Short for Asymmetric Digital Subscriber Line. A variation of the DSL technologies that is most familiar to home and small business users. ADSL is called "asymmetric" because most of its
ARP
Short for Address Resolution Protocol, a TCP/IP protocol used to convert an IP address into a physical address, such as an Ethernet address. A host wishing to obtain a physical address broadcasts an ARP request onto the TCP/IP network. The host on the network that has the IP address in the request then replies with its physical hardware address.
There is also Reverse ARP (RARP) which can be used by a host to discover its IP address. In this case, the host broadcasts its physical address and a RARP server replies with the host’s IP address.
ATM
Short for Asynchronous Transfer Mode, a network technology based on transferring data in cells or packets of a fixed size. The cell used with ATM is relatively small compared to units used with older technologies. The small, constant cell size allows ATM equipment to transmit video, audio, and computer data over the same network, and assure that no single type of data hogs the line.
Authenticate
To verify a user’s identity, such as by prompting for a password.

Bridging
Passing data from your network to your ISP and vice versa using the hardware addresses of the devices at each location. Bridging contrasts with routing, which can add more intelligence to data transfers by using network addresses instead. The HM210dp/di can perform both routing and bridging. Typically, when both functions are enabled, the device routes IP data and bridges all other types of data. See also Routing.
