System and method for special signaling with customer premises equipment
First Claim
1. A system for special signaling with customer premises equipment, comprising:
- loop termination equipment coupled to a local loop and comprising a signal generator and a plurality of digital subscriber line (DSL) modems; and
customer premises equipment coupled to the local loop;
the customer premises equipment and loop termination equipment operable to communicate across a communication link established on the local loop;
the loop termination equipment further operable to determine that none of the DSL modems are available to service the customer premises equipment and, in response, to control characteristics of a signal generated by the signal generator and to provide the signal to the customer premises equipment as special signaling, the signal having a frequency that does not substantially interfere with voice traffic on the local loop.

Abstract
A system and method are provided for special signaling with customer premises equipment. The system includes loop termination equipment coupled to a local loop and comprising a signal generator. The system also includes customer premises equipment coupled to the local loop. The customer premises equipment and loop termination equipment are operable to communicate across a communication link established on the local loop. The loop termination equipment is further operable to control characteristics of a signal generated by the signal generator and to provide the signal to the customer premises equipment as special signaling where the signal has a frequency that does not substantially interfere with voice traffic on the local loop. The special signaling can be used to implement enhanced service to the customer premises including busy signal, queued data request processing, push data and telephony services.

18. Loop termination equipment comprising:
-
a signal generator;
a plurality of digital subscriber line (DSL) modems; and
a digital subscriber line access multiplexer (DSLAM) coupled to customer premises equipment using a local loop, the DSLAM operable to receive a signal indicating a desire to communicate data to the customer premises equipment and, in response to the signal, to control characteristics of a wake up signal generated by the signal generator and to provide the wake up signal to the customer premises equipment, the wake up signal requesting a data connection with the customer premises equipment and having a frequency that does not substantially interfere with voice traffic on the local loop. - View Dependent Claims (19, 20)
receive the signal indicating a desire to communicate data to the customer premises equipment from a server;
receive a request for service from the customer premises equipment responsive to the wake up signal;
establish a DSL connection with the customer premises equipment using a selected one of the DSL modems in response to the request for service;
receive an acknowledgement of the wake up signal from the customer premises equipment; and
forward the acknowledgement to the server.
