AAL5
ATM Adaptation Layer - This layer maps higher layer user data into ATM cells, making the data suitable for transport through the
ATM network.

ADSL
Asymmetric digital subscriber line.

ATM
Asynchronous Transfer Mode - A cell-based data transfer technique in which channel demand determines packet allocation.
ATM offers fast packet technology, real time; demand led switching for efficient use of network resources.

AWG
American Wire Gauge - The measurement of thickness of a wire.

Bridge
A device connects two or more physical networks and forwards packets between them. Bridges can usually be made to filter packets,
that is, to forward only certain traffic. Related devices are: repeaters which simply forward electrical signals from one cable to the
other and full-fledged routers which make routing decisions based on several criteria.

Broadband
Characteristic of any network multiplexes independent network carriers onto a single cable. Broadband technology allows several
networks to coexist on one single cable; traffic from one network does not interfere with traffic from another. Broadcast a packet
delivery system where a copy of a given packet is given to all hosts attached to the network. Example: Ethernet.

CO

CPE
Customer Premises Equipment located in a user's premises.

DHCP (Dynamic Host Configuration Protocol)
DHCP is software that automatically assigns IP addresses to client stations logging onto a TCP/IP network. DHCP eliminates having
to manually assign permanent IP addresses to every device on your network. DHCP software typically runs in servers and is also
found in network devices such as Routers.

DMT
Discrete Multi-Tone frequency signal modulation

Downstream rate
The line rate for return messages or data transfers from the network machine to the user's premises machine.

DSLAM
