Abstract
A method and system for dynamic utilization of the available bandwidth on existing ISDN and other broadband links is disclosed. In a first preferred embodiment, an efficient link-utilization system comprises first and second telecommunication nodes connected by one or more ISDN links or other broadband connections. When a caller desires to place a call from a communication device served by the first telecommunication node to a communication device served by the second telecommunication node, the first telecommunication node determines whether an existing broadband link connecting the first and second telecommunication nodes has sufficient available bandwidth to carry the call in compressed form from the calling communication device to the called communication device. If such an existing telephonic link is identified, the first telecommunications node compresses the transmission received from the caller and transmits the compressed transmission to the second telecommunications node via the available bandwidth on the existing telephonic link. The second telecommunications node decompresses the transmission and transmits the decompressed transmission to the called party. The disclosed…
