Abstract
A multiple-protection system in a communication device, includes: a plurality of working units; at least one protection unit; and a unit controller controlling unit switching from a failed working unit to a protection unit, wherein each of the plurality of working units and the protection unit comprises: a plurality of working circuit modules; at least one protection circuit module; and a module controller controlling module switching from a failed working circuit module to a protection circuit module, wherein, when module protection cannot be made by the module switching, the unit switching is performed.
Claims10
A multiple-protection system in a communication device, comprising:
- a plurality of working units;
- at least one protection unit;
- and
- a unit controller controlling unit switching from a failed working unit to a protection unit,
- wherein each of the plurality of working units and the protection unit comprises:
- a plurality of working circuit modules;
- at least one protection circuit module;
- and
- a module controller controlling module switching from a failed working circuit module to a protection circuit module,
- wherein, when module protection cannot be made by the module switching, the unit switching is performed.
A multiple-protection method in a communication device which comprises a plurality of working units and at least one protection unit, wherein each of the plurality of working units and the protection unit comprises a plurality of working circuit modules and at least one protection circuit module, the method comprising:
- when a module failure is detected, performing module switching from a failed working circuit module to a protection circuit module for module protection within a working unit;
- when the module protection within the working unit cannot be made by the module switching, performing unit switching from a failed working unit to a protection unit for unit protection.
A recording medium storing a program which instructs a computer to perform multiple-protection in a communication device which comprises a plurality of working units and at least one protection unit, wherein each of the plurality of working units and the protection unit comprises a plurality of working circuit modules and at least one protection circuit module, the program comprising:
- when a module failure is detected, performing module switching from a failed working circuit module to a protection circuit module for module protection within a working unit;
- when the module protection within the working unit cannot be made by the module switching, performing unit switching from a failed working unit to a protection unit for unit protection.
