ISP
A local area network provides a full-time, high-bandwidth connection over a limited area, such as a
LAN
building, campus, office, or home. The computers and other devices you connect to your voice
gateway, except for the telephones, form a LAN. Ethernet is the most widely used LAN standard.
The Media Access Control address uniquely identifies each device that can be connected to an
MAC address
Ethernet network. It is permanently written to read-only memory (ROM) at the factory and printed on
your VT2142.
