Asymmetric cross-connect system
View Patent ↗An asymmetric cross-connect system, constituted of: a cross-connect circuitry; and a control circuitry, wherein the cross-connect circuitry comprises a plurality of adaptive equalizers and a plurality of fixed equalizers, wherein the plurality of adaptive equalizers are in electrical communication with a multi-purpose port of a user device and each of the plurality of fixed equalizers are in electrical communication with a respective output of a processor of the user device, and wherein the cross-connect circuitry is arranged, responsive to the control circuitry, to provide a communication path between one of the outputs the processor and the multi-purpose port.
1. An asymmetric cross-connect system, comprising: a cross-connect circuitry; and a control circuitry, wherein said cross-connect circuitry comprises a plurality of adaptive equalizers and a plurality of fixed equalizers, wherein said plurality of adaptive equalizers are each arranged for connection to a respective multi-purpose port of a user device and each of said plurality of fixed equalizers are arranged for connection to a respective output of a processor of the user device, and wherein said cross-connect circuitry is arranged, responsive to said control circuitry, to provide a communication path between a selected one of the outputs of the processor and a selected one of the multi-purpose ports of the user device.
2. The system of claim 1 , wherein each of said adaptive equalizers comprises a continuous time linear equalizer and each of said fixed equalizers comprises a finite impulse response filter.
3. The system of claim 1 , further comprising a user input module, each of said fixed equalizers arranged to be adjusted responsive to a respective user input at said user input module.
4. The system of claim 3 , wherein each of said fixed equalizers comprises a finite impulse response filter, taps of said finite impulse response filter arranged to be adjusted responsive said respective user input.
5. A multi-purpose port cross-connecting method, the method comprising: determining the type of an external device coupled to a multi-purpose port of a user device; controlling a cross-connect circuitry to create a communication path between the multi-purpose port and a particular output of a processor which is associated with the external device, the cross-connect circuitry comprising a plurality of adaptive equalizers and a plurality of fixed equalizers; equalizing signals transmitted from the processor to the cross-connect circuitry with a respective one of the plurality of fixed equalizers; and equalizing signals transmitted from the external device to the cross-connect circuitry with a respective one of the plurality of adaptive equalizers.
6. The method of claim 5 , wherein each of the adaptive equalizers comprises a continuous time linear equalizer and each of the fixed equalizers comprises a finite impulse response filter.
7. The method of claim 5 , further comprising, responsive to a user input, adjusting a respective one of the plurality of fixed equalizers.
8. The method of claim 7 , wherein each of the fixed equalizers comprises a finite impulse response filter, taps of said finite impulse response filter arranged to be adjusted responsive the respective user input.
