Abstract

Various exemplary embodiments relate to a telecommunications system. The telecommunications system may include at least one actively operating component and at least one redundant component. The redundant component may include a first subcircuitry for receiving synchronization information and at least one second subcircuitry. The first subcircuitry may be activated independently of the second subcircuitry.

Claims

1. A telecommunications component comprising:

a circuit configured to provide standby redundancy to another device, the circuit comprising;

a first subcircuitry configured to receive synchronization information,

a second subcircuitry configured to utilize the synchronization information received by the first subcircuitry;

wherein the first subcircuitry is activated independently of the second subcircuitry;

a digital power manager that activates the first subcircuitry and the second subcircuitry;

wherein the second subcircuitry is activated intermittently by the digital power manager to update the telecommunications component with the synchronization information and wherein the second subcircuitry consumes more power when activated, and

wherein the digital power manager activates the first subcircuitry and second subcircuitry according to a received power profile.

2. The telecommunications component of claim 1, wherein the digital power manager activates the first subcircuitry and the second subcircuitry by independently supplying power to the first subcircuitry and the second subcircuitry.

3. The telecommunications component of claim 1, wherein the first subcircuitry is activated and the second subcircuitry is deactivated.

4. The telecommunications component of claim 1, wherein the first subcircuitry receives synchronization information from the other device and the other device comprises at least one other telecommunications component.

5. The telecommunications component of claim 4, wherein the at least one other redundant telecommunications component is an actively operating telecommunications component.

6. The telecommunications component of claim 1, wherein the received power profile includes an instruction to achieve a desired power usage metric.

7. The telecommunications component of claim 1, wherein the telecommunications component is at least one of a control card, switching fabric, power supply, cooling unit, uplink, and line card.

8. The telecommunications component of claim 1, wherein the synchronization information is at least one of dynamic information and static information.

9. The telecommunications component of claim 1, wherein the first subcircuitry stores system restore information.

10. A telecommunications system comprising:

at least one actively operating component;

at least one redundant component having a first subcircuitry for receiving synchronization information and at least one second subcircuitry,

wherein the first subcircuitry is activated independently of the at least one second subcircuitry; and

a digital power manager that activates the first subcircuitry and the at least one second subcircuitry,

wherein the at least one second subcircuitry is activated intermittently to update the component with the synchronization information and wherein the second subcircuitry consumes more power when activated, and

wherein, the digital power manager activates the first subcircuitry and second subcircuitry according to a received power profile.

11. The telecommunications system of claim 10, wherein the digital power manager activates the first subcircuitry and the at least one second subcircuitry by independently supplying power to the first subcircuitry and the at least one second subcircuitry.

12. The telecommunications system of claim 10, wherein the first subcircuitry is activated and the at least one second subcircuitry is deactivated.

13. The telecommunications system of claim 10, wherein the first subcircuitry receives synchronization information from the at least one actively operating component.

14. The telecommunications system of claim 10, further comprising:

a second redundant component,

wherein the first subcircuitry receives synchronization information from the second redundant component.

15. The telecommunications system of claim 10, wherein the received power profile includes an instruction to achieve a desired power usage metric.

16. The telecommunications system of claim 10, wherein the synchronization information is at least one of dynamic information and static information.

17. The telecommunications system of claim 10, wherein the first subcircuitry stores system restore information.
