Abstract
A communications device and method for effectively managing bandwidth within a telecommunications network carrying both time division multiplexed signals as well as data signals. The communications device having dialable TDM/cell and/or packet-based bandwidth management capability so that a network operator can select to manage bandwidth for any particular signal on in STS, VT, or cell or packet basis.
Claims17
A communications device comprising:
- at least an input port, said input port configured so as to accept an input signal from a network and to forward an STS-n signal comprising the input signal;
- at least two from among the set consisting of:
- a cell-based bandwidth manager;
- a packet-based bandwidth manager;
- a STS bandwidth manager;
- and
- a VT bandwidth manager;
- and
- a selector, said selector being capable of selectively routing said STS-n signal to the cell-based bandwidth manager, the packet-based bandwidth manager, the STS bandwidth manager, or the VT bandwidth manager.
A communications device comprising:
- a plurality of input ports, said input ports configured so as to accept input signals from a network and to forward STS-n signals comprising the input signals;
- a cell/packet switching fabric;
- a STS switching fabric;
- a VT switching fabric;
- a selector, said selector being capable of selectively routing said STS-n signals to said data switching fabric, said STS switching fabric or said VT switching fabric;
- and
- at least an output port, said output port being capable of receiving signals from said cell/packet switching fabric, said STS switching fabric and said VT switching fabric and outputting said received signals to said network.
A method for managing bandwidth of signals on a telecommunications network comprising the steps of:
- accepting an input signal from said telecommunications network and forwarding an STS-n signal comprising the input signal;
- determining whether to manage said bandwidth of said STS-n signal on an STS level, on a VT level or on a cell/packet level;
- managing said bandwidth of said STS-n signal in accordance with said determination;
- outputting a managed signal.
A communications device comprising:
- a plurality of input ports, said input ports configured so as to accept input signals from a network and forward STS-n signals comprising the input signals;
- a cell/packet switching fabric;
- a STS switching fabric;
- a VT switching fabric;
- a plurality of connectors each of said plurality of connectors providing connectivity between one of said plurality of input ports and at least one of said cell/packet switching fabric, said STS switching fabric and said VT switching fabric;
- and
- at least an output port, said output port being capable of receiving signals from said cell/packet switching fabric, said STS switching fabric and said VT switching fabric and outputting said received signals to said network.
