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 ITU-T recommendations V.27 (up
to 4.8 kbit/s) and V.29 (up to 9.6 kbit/s). Fax relay is only supported on MVP-
E FPs.
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.
