Abstract
A cable including circuitry for asserting information to a user or external device and a system including such a cable. The cable can include conductors, a memory storing cable data, and circuitry configured to respond to a request received on at least one of the conductors by accessing at least some of the cable data and asserting the accessed data serially to at least one of the conductors (e.g., for transmission to an external device). Other aspects of the invention are methods for accessing cable data stored in a cable and optionally using the data (e.g., to implement equalization). The cable data can be indicative of all or some of cable type, grade, speed, length, and impedance, a date code, a frequency-dependent attenuation table, far-end crosstalk and EMI-related coefficients, common mode radiation, intra pair skew, and other information. The cable can include a radiation-emitting element and circuitry for generating driving signals for causing the radiation-emitting element to produce an appropriate color, brightness, and/or blinking pattern.
