Discovering connection of passive cables
First Claim
1. A subsystem to enable discovering connection of passive cables, the system comprising:
- a signal driver/receiver to send and receive data and signals over a passive cable; and
a connection discovery engine to access a low-level enable or disable control of the signal driver/receiver and a low-level loss-of-signal (LOS) control of the signal driver/receiver,wherein the connection discovery engine modulates the low-level enable or disable control to generate and send a local unique ID of the signal driver/receiver over the passive cable, and wherein the connection discovery engine monitors timings of transitions on the low-level LOS control to receive, over the passive cable, a remote unique ID of a signal driver/receiver in a second subsystem connected by the passive cable.

Abstract
In one example in accordance with the present disclosure, a subsystem is provided. The subsystem includes a signal driver/receiver capable of sending and receiving data and signals over a passive cable. The subsystem includes a connection discovery engine to access a low-level enable or disable control of the signal driver/receiver and a low-level loss-of-signal (LOS) control of the signal driver/receiver. The connection discovery engine modulates the enable or disable control to send a local unique ID of the signal driver/receiver over the passive cable. The connection discovery engine monitors timings of transitions on the LOS control to receive, over the passive cable, a remote unique ID of a signal driver/receiver in a second subsystem connected by the passive cable.

10. A method executed in a first subsystem to enable discovering connection of passive cables, the method comprising:
-
accessing a low-level enable or disable control of a signal driver/receiver in the first subsystem and a low-level loss-of-signal (LOS) control of the signal driver/receiver, wherein the signal driver/receiver allows sending and receiving data and signals over a passive cable; generating and sending a local unique ID of the signal driver/receiver over the passive cable by modulating the low-level enable or disable control; and receiving, over the passive cable, a remote unique ID of a signal driver/receiver in a second subsystem connected by the passive cable by monitoring timings of transitions on the low-level LOS control. - View Dependent Claims (11, 12, 13)

14. A machine-readable non-transitory storage medium encoded with instructions for discovering connection of passive cables, the instructions executable by a processor of a first subsystem to cause the first subsystem to:
-
access a low-level enable or disable control of a signal driver/receiver in the subsystem and a low-level loss-of-signal (LOS) control of the signal driver/receiver, wherein the signal driver/receiver allows sending and receiving data and signals over a passive cable; generate and send beacons over the passive cable to a second subsystem by modulating the low-level enable or disable control, wherein these beacons are used to determine that some device is connected on the other end of the passive cable; and receive, over the passive cable, beacons from the second subsystem connected by the passive cable by monitoring timings of transitions on the low-level LOS control. - View Dependent Claims (15)
