1. An intermediate device for use in a signaling system having an upstream device and plural terminating devices, the intermediate device comprising:

  • a set of first interfaces, each first interface to operatively connect to a respective one of the plural terminating devices via a dedicated signaling link external to the intermediate device;

    a second interface to operatively connect to the upstream device via a dedicated signaling link external to the intermediate device;

    circuitry to provide communications from the plural terminating devices to the upstream device via the second interface; and

    physical layer circuitry to perform presence detection for the set of first interfaces, the intermediate device to provide presence detection information from the physical layer circuitry for the plural terminating devices to the upstream device.
