NWAdmin is a NetWare administration utility based on Internetwork Packet Exchange (IPX) and Sequenced Packet Exchange (SPX). It provides a graphical interface for administration tasks such as editing the NDS tree, managing disk storage, setting up security and user access rights, configuring network devices, or managing e-mail systems.

NXX is a three-digit prefix that identifies a local exchange or CO. "N" represents any digit except 0 or 1, and "X" represents any digit from 0 to 9. The prefix was formerly called an "NNX."

MRS enables the deaf, hard of hearing, or persons experiencing difficulty with speech to have telephone conversations with hearing individuals using a TTY or TDD. Relay service operators relay voice conversations to and from teletype format on behalf of the call parties. No record of the conversation is kept.

MTP is the three sublayer component of the SS7 protocol stack, used to control physical signaling [Message Transfer Part 1 (MTP1)], point to point message delivery [Message Transfer Part 2 (MTP2)], and signal routing between transfer points [Message Transfer Part 3 (MTP3)].

MTP1 is the SS7 protocol that corresponds to the OSI model physical layer. MTP1 is responsible for physical signaling between transfer points.

MTP2 is the SS7 protocol that corresponds to the OSI model data link layer. MTP is responsible for point-to-point message delivery, flow control, message retransmission, and failover.

MTP3 is the SS7 protocol that corresponds to the OSI model network layer. MTP3 is responsible for routing signaling messages across the SS7 network.

Message-Associated User-to-User Information (MA-UUI). MA-UUI is an ISDN D channel information exchange process that passes call information between users within the ISDN call control (Q.931) messages.

A messaging portal is also known as a collaborative processing enterprise information portal or communications-enabled portal. It is a site intended for use in a collaborative environment, where multiple network services, such as e-mail, voice messaging, document sharing, database access, and other enterprise services are presented to the user in a [..]
