non-real time variable bit rate (NRT-VBR)
A QOS class that defines the throughput connection history as bursty with an
expected low cell loss ratio (CLR) for transmitted cells. NRT-VBR supports
statistical multiplexing for connections, with no associated delay bounds. NRT-
VBR is designed to support non-real time applications.
non-operational card
A processor card that cannot provide service. The card can be absent,
unprovisioned, locked, or has not yet finished loading its software.
non-switched voice
