ATIS is the leading technical planning and standards development organization committed to the rapid development of global, market-driven standards for the information, entertainment and communications industry.
In Personal Communications Service (PCS,) the assigning and controlling of wireless links for terminal network connections. Note: Wireless mobility management provides an "alerting" function for call completion to a wireless terminal, monitors wireless link performance to determine when an automatic link transfer is required, and coordinates link transfers between wireless access interfaces.
Industry:Telecommunications
In personal communications service (PCS,) the ability for the network to provide user access to features and to accept user service requests specifying the type of bearer services or supplementary service that the users want to receive from the PCS network.
Industry:Telecommunications
In personal communications service (PCS,) terminal access to a network in which there is no set relationship between a terminal and the access interface. Note: The access interface and the terminal each has its own separate "identifiers. " The terminal may be moved from one access interface to another while maintaining the terminal's unique identity.
Industry:Telecommunications
In personal communications service (PCS,) terminal access to a network in which there is a set relationship between a terminal and the access interface. Note: A single "identifier" serves for both the access interface and the terminal. If the terminal moves to another access interface, that terminal assumes the identity of the new interface.
Industry:Telecommunications
In personal communications service (PCS,) (a) providing authentication of terminal information, (b) maintaining terminal location and capability information for each terminal, and (c) providing translation between terminal identification and location (routing address) for the completion of calls to terminals.
Industry:Telecommunications
In PCS (personal communication service,) the capability that (a) provides authentication of user identification and maintains user location information in the service profile, (b) controls the completion of calls based on user-specified incoming call management contained in the service profile, (c) provides translation between user identification and identification of the terminal currently associated with the user for the completion of calls to the use's current location, and (d) controls the services and features available to the user based on the user's subscription and in conjunction with user-specified terminal access configurations.
Industry:Telecommunications
In PCM systems, a set of consecutive frames in which the position of each frame can be identified by reference to a multiframe alignment signal. Note: The multiframe alignment signal does not necessarily occur, in whole or in part, in each multiframe.
Industry:Telecommunications
In PCM systems, a code constructed so that the frequency spectrum resulting from the transmission of any code word has no dc component. 2. In PCM, a code that has a finite digital sum variation.
Industry:Telecommunications
In parallel transmission, the difference in arrival time of bits transmitted at the same time. 2. For data recorded on multichannel magnetic tape, the difference between reading times of bits recorded in a single transverse line. Note: Skew is usually interpreted to mean the difference in reading times between bits recorded on the tracks at the extremities, i.e., edges, of the tape. 3. In facsimile systems, the angular deviation of the received frame from rectangularity caused by asynchronism between the scanner and the recorder. Note: Skew is expressed numerically as the tangent of the deviation angle. 4. In facsimile, the angle between the scanning line, or recording line, and the perpendicular to the paper path.
Industry:Telecommunications
In packet-switched networks, the simultaneous use of multiple links for the transmission of different segments of the same message unit. Note: Use of multilink operation is intended to increase the effective rate of message transmission. Multilink operation requires special procedures for multiplexing/demultiplexing control.
