GLOSSARY

Media Access Control (MAC)

A portion of the networking protocol that governs access to the transmission medium, facilitating the exchange of data between network nodes.

Media Dependent Interface (MDI)

The IEEE standard for the UTP interface to twisted-pair Ethernet. MDI defines a straight-through pin assignment that allows you to connect the router to any workstation or server that has a properly installed network adapter card using the supplied crossover cable. Pin-out assignments are shown in Appendix B.

Media Dependent Interface - Crossed (MDI-X)

MDI-X port types cross the receive and transmit signals internally, and can be used with straight-through cable to connect the router to a similar networking device (such as a hub or switch). Note that if you use the supplied crossover cable to connect to a similar networking device, then you must connect to an MDI port on the other device. Pin-out assignments are shown in Appendix B.

Multiprotocol Encapsulation

A method whereby multiple protocol types can be passed over a single

ATM PVC.

Network Address Translation (NAT)

A standard that enables a local-area network (LAN) to use one set of IP addresses for external traffic and a second set of addresses for internal traffic.

Network Address Port Translation (NAPT)

NAPT is a special case of NAT, where internal IP numbers are hidden behind a single external addresses, allowing you to connect many local users to the Internet with a single-user ISP account. With NAPT, an
