1. A method for negotiating pin assignment for a cabling interface, the method comprising:
discovering, by the cabling interface, an attached device through an interrogation from a connected port by detecting a low voltage presence pulse transmitted through a designated pin of the cabling interface; responsive to discovering the attached device, setting the designated pin to a unassigned state for reuse in a subsequent communication between the cabling interface and the attached device; performing, by the cabling interface, a handshake with the attached device, wherein the handshake shares information on the protocols, bandwidth needs, streams and pins supported by the attached device; declaring, by the cabling interface, a set of supported streams needed for communication by the cabling interface; negotiate pin layout, by the cabling interface, for each streams that will be used for communication between the cabling interface and the attached device; and assigning, by the cabling interface, pins based on needs of the attached device and needs of the cabling interface. |
