GLOSSARY

Transmission Control Protocol/Internet Protocol (TCP/IP)

Protocol suite that includes TCP as the primary transport protocol, and IP as the network layer protocol.

UTP

Unshielded twisted-pair cable.

User Datagram Protocol (UDP)

UDP provides a datagram mode for packet-switched communications. It uses IP as the underlying transport mechanism to provide access to IP-like services. UDP packets are delivered just like IP packets – connection-less datagrams that may be discarded before reaching their targets. UDP is useful when TCP would be too complex, too slow, or just unnecessary.

Very high data rate Digital Subscriber Line (VDSL)

A family of digital telecommunications protocols designed to allow high speed data communication at data rates from below 1 Mbps to 52.8 Mbps with corresponding maximum reach ranging from 4500 feet to 1000 feet using 24 gauge twisted pair cable over the existing copper telephone lines between end-users and service providers.

Very high data rate Digital Subscriber Line 2 (VDSL2)

VDSL2 as defined in ITU-T Recommendation G.993.2 is an enhancement to the first VDSL standard (G.993.1). It supports transmission at a bi-directional net data rate (the sum of upstream and downstream rates) of up to 200 Mbps on twisted pair cables using a bandwidth of up to 30 MHz.
