Splitter
A filter to separate DSL signals from POTS signals to prevent mutual interference.
Straight-through Port
An RJ-45 port which does not cross the receive and transmit signals internally
(MDI) so it can be connected with straight-through twisted-pair cable to any device
having a crossover port (MDI-X). Also referred to as a “Daisy-Chain” port.
Switched Ports
Ports that are on separate collision domains or LAN segments.
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.
VDSL
Very high data rate Digital Subscriber Line: 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 of 24 gauge twisted pair cable over the existing copper
telephone lines between end-users and telephone companies.
Virtual LAN (VLAN)
A Virtual LAN is a collection of network nodes that share the same collision
domain regardless of their physical location or connection point in the network. A
VLAN serves as a logical workgroup with no physical barriers, allowing users to
share information and resources as though located on the same LAN.
