framing

G

H

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

Facilities Restriction Level.

FX

Foreign exchange.

Gateway

(1) protocol converter (2) a node between network segments.

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.
