MIL-STD-188-176
3.1.9 Broadband . A service or system requiring transmission channels to support rates greater than the ISDN primary rate.
3.1.10 Broadband terminal (BT) . User equipment at the location where the user-to-network interface (UNI) terminates.
The BT may be a single user equipment or it may act as aggregator of other tributary devices.
3.1.11 Cell. An ATM Layer protocol data unit. A cell consists of a 5-byte header and a 48-byte payload. The primary role of the header is to identify cells that belong to the same connection.
3.1.12 Non-ATM interface . A user-to-network interface that does not comply with the ATM Forum's ATM UNI specification.
3.1.13 Permanent virtual channel connection (PVCC) . A virtual channel that provides a long-term connection between ATM entities.
NOTE: PVCCs are preestablished by network managers and eliminate the need for repeated call setup and release.
3.1.14 Profile. A set of one or more base standards and, where applicable, the identification of chosen classes, subsets, options, and parameters of those base standards necessary for accomplishing a particular function.
3.1.15 Switched virtual channel connection (SVCC) . A virtual channel that is established on a per-call basis between ATM entities and released when the call is completed.
3.1.16 Virtual channel . A communications channel that provides for the sequential unidirectional transport of ATM cells.
3.1.17 Virtual channel connection . A bidirectional connection between ATM end points that provides sequential transport of ATM cells in each direction. The bandwidth is allocated separately in each direction.
3.1.18 Virtual path . A logical association or bundle of virtual channels.
3.2 Abbreviations and acronyms . The abbreviations and acronyms used in this standard are defined as follows:
AA ATM adapter
AAL ATM adaptation layer
