Abstract
An adaptation mechanism monitors, maintains and controls quality of voice-grade for communications among end-systems in a distributed PBX topology, thereby providing an enhanced Quality of Service (QoS) for the network.
Claims32
A method of dynamically adapting a PBX network to maintain a Quality of Service level in the network comprising:
- identifying a parameter associated with a data packet transported across the network;
- measuring the parameter after the data packet is transported across the network;
- and
- enabling bandwidth optimization of the network bandwidth when said measured parameter differs from a predetermined value, comprising:
- determining whether at least one first channel is inactive;
- and
- re-mapping at least one active second channel to at least one available inactive first channel.

An apparatus for dynamically adapting a PBX network to maintain a Quality of Service level in the network comprising:
- first and second PBX cabinets interconnected in a local area network configuration for sending and receiving data packets;
- a register in connection with at least one of said cabinets for storing a value associated with one or more packets transported across the network;
- a comparator for comparing said stored value with a predetermined value;
- and
- an optimization mechanism for adjusting the bandwidth of the network when said stored value differs from a predetermined value, comprising:
- determining whether at least one first channel is inactive;
- and
- re-mapping at least one active second channel to at least one available inactive first channel.

An apparatus for dynamically adapting a PBX network to maintain a Quality of Service level in the network comprising:
- a parameter identifying mechanism configured to identify a parameter associated with a data packet transported across the network;
- a parameter measuring device configured to measure the parameter after the data packet is transported across the network;
- and
- an optimization enabling device configured to optimize the bandwidth of the network when said measured parameter differs from a predetermined value, wherein the bandwidth optimization comprises:
- determining whether at least one first channel is inactive;
- and
- re-mapping at least one active second channel to at least one available inactive first channel.
