List of terms
fair buffer allocation (FBA)
Guarantees that connections or classes receive a fair portion of the total available cell buffers in a function processor.
FAS
See frame alignment signal (FAS) (page 54).
fast management information protocol (FMIP)
The proprietary fast management information protocol (based on OSI/ASN.1 principles) implemented between a Nortel Multiservice Switch node and Nortel Multiservice Data Manager workstation, to manage the node.
FAX handling
See facsimile handling (page 51).
fax idle suppression (FIS)
A function performed by Nortel Multiservice Switch nodes when processing facsimile transmissions, which saves bandwidth by not transmitting the idle portions between data bursts. During a typical facsimile transmission, FIS can reduce bandwidth use by as much as 20 percent in the sending direction and 80 percent in the receiving direction.
fax relay
A modulation/demodulation technique used by the voice transport service for transmitting facsimile traffic across a Nortel Multiservice Switch network. The types of modulation supported are based on
FBA
See fair buffer allocation (FBA) (page 52).
FCI
See forward congestion indication (FCI) (page 54).
feature
Nortel Multiservice Switch applications consist of features (for example, frame relay UNI is a feature of the frame relay application). Each processor card is provisioned to run a set of features.
feature list (FL)
The list of provisionable features that can be loaded onto a processor. The feature list is a provisionable attribute of a logical processor type.
