Glossary of Terms MJ: Modular Jack. A jack used for connecting voice cables to a faceplate, as for a telephone. MMJ: Modified Modular Jack. These are the 6-pin connectors used to connect serial terminal lines to terminal devices. MMJs can be distinguished from the similar RJ12 jacks by having a side-locking tab, rather than a center-mounted one. Modem: A modulator-demodulator device for changing transmission signals from digital to analog for transmission over phone lines. Used in pairs, one is required at each end of the line. MOP: Maintenance Operations Protocol, a DEC protocol used for remote communications between hosts and servers. Multicast: A multicast is a message that is sent out to multiple devices on the network by a host. Multilink PPP: The ability of a dialup device to allocate more than one channel of bandwidth to a particular connection. Generally, this is termed to be the ability of an ISDN device to bond two B-channels together into a single data pipe, but some vendors can perform the same function with asychronous dial-up connections over modems by having a second connection initiated to support the additional bandwidth requirements. Multiplexer: A device that allows several users to share a single circuit. It funnels different data streams into a single stream. At the other end of the communications link, another multiplexer reverses the process by splitting the data stream back into the original streams. Multiplexing: Transmitting multiple signals simultaneously on a single channel. Multiport Repeater: A repeater, either standalone or connected to standard Ethernet cable, for interconnecting up to eight Thinwire Ethernet segments. 11-10 DSTni-XPress DR User Guide
