Abstract
A disconnect unit may include a first interface, configured to communicate with an accessory, a second interface, configured to communicate with a communication device, a relay, configured to physically connect and disconnect a communication path between the first interface and the second interface, and a codec unit, configured to maintain a software-level connection with the communication device via the second interface on behalf of the accessory.
Claims20
A disconnect unit, comprising:
- a first interface, configured to communicate with an accessory;
- a second interface, configured to communicate with a communication device;
- a relay, configured to physically connect a communication path between the first interface and the second interface;
- and
- a codec unit, configured to maintain a software-level connection with the communication device via the second interface on behalf of the accessory.
An electrical circuit, comprising:
- a first interface, configured to communicate with an accessory;
- a second interface, configured to communicate with a communication device;
- a relay, configured to physically connect a communication path between the first interface and the second interface;
- and
- a codec unit, configured to maintain a software-level connection with the communication device via the second interface on behalf of the accessory.
A method of positively disconnecting a communication path between a first interface in communication with a communication device and a second interface in communication with an accessory to prevent inadvertent signal transmissions, comprising:
- physically disconnecting the communication path between the first interface and the second interface in a default operating state by a relay disposed along the signal path;
- maintaining a software-level connection with the communication device via the second interface on behalf of the accessory;
- and
- physically connecting the communication path in a connected operating state to enable signal communication between the accessory and the communication device.
