A telecommunications transmission pathway and associated equipment.
facility-associated signaling (FAS)
Signaling for which a D-channel carries signaling only for those channels on
the same physical interface.
FAS
Facility-associated signaling
framing
The data-formatting conventions that allow a receiver to synchronize with the
transmitting end of a circuit. For example, T-1 frames contain an 8-bit sample
from each of the 24 channels on the interface (192 bits total) plus a framing bit
(for a total of 193 bits). Each framing bit marks the end of a timed sample the
input at the transmission end.
FRL
FX
Facilities Restriction Level.
Foreign exchange.
G
Gateway
(1) protocol converter (2) a node between network segments.
H H.320
The most common standard for videoconferencing over ISDN BRI circuits.
H.320-compatible systems can communicate with each other even when they
rely on dissimilar hardware and software.
H.323
A specification that sets standards for multimedia communications between
LANs and telephony networks, such as ISDN.
