Patent ID: 7636523

Claim:
Apparatus, comprising: first receiver circuitry configured to receive, via a first communication channel, first data transmitted from within the apparatus in the form of an optical signal; and second receiver circuitry configured to receive, via a second communication channel, second data transmitted from within the apparatus; wherein the first receiver circuitry has a first mode in which it is not operable to receive the first data, and a second mode in which it is operable to receive the first data, and in response to the second receiver circuitry receiving the second data when the first receiver circuitry is in the first mode, the first receiver circuitry is operable to switch from being in the first mode to being in the second mode, wherein the first receiver circuitry comprises an opto-electronic device, wherein the second data is in the form of an optical signal and the second receiver circuitry comprises a second opto-electronic device, and wherein the first and second opto-electronic devices are provided in a same package.
