MMP

Multichassis Multilink PPP: A protocol that supplies MLP support

across multiple routers and access servers. MMP enables several routers and
access servers to work as a single, large dial-up pool with one network
address and ISDN access number. MMP successfully supports packet frag-
menting and reassembly when the user connection is split between two phys-
ical access devices.

modem

modulator-demodulator: A device that converts digital signals to

analog and vice versa so that digital information can be transmitted over analog
communication facilities, such as voice-grade telephone lines. This is
achieved by converting digital signals at the source to analog for transmis-
sion and reconverting the analog signals back into digital form at the desti-
nation. See also: modulation and demodulation.

modemcap database

Stores modem initialization strings on the router

for use in auto-detection and configuration.

modem eliminator

A mechanism that makes possible a connection

between two DTE devices without modems by simulating the commands
and physical signaling required.

modulation

The process of modifying some characteristic of an electrical

signal, such as amplitude (AM) or frequency (FM), in order to represent dig-
ital or analog information. See also: AM.

MOSPF

Multicast OSPF: An extension of the OSPF unicast protocol that

enables IP multicast routing within the domain. See also: OSPF.

MP bonding

MultiPoint bonding: A process of linking two or more phys-

ical connections into a single logical channel. This may use two or more
analog lines and two or more modems, for example.

MPOA

Multiprotocol over ATM: An effort by the ATM Forum to stan-

dardize how existing and future Network layer protocols such as IP, Ipv6,
AppleTalk, and IPX run over an ATM network with directly attached hosts,
routers, and multilayer LAN switches.

MSFC

Multilayer Switch Feature Card: A route processor (parallel to an

RSM, or Route Switch Module) that is installed as a daughter card on Cisco
Catalyst 6000 series switches. See also: RSM.
