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 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.
