Abstract: A method that uses a test system at one end of a communication link to test the communication link for high speed service by coupling the test system to the communication link, placing a telephonic call to telephonic equipment locate d at an other end of the communication link and testing the communication link with the te st system after the call has been terminated at the telephonic equipment.

Abstract: A method and apparatus for increasing the allowable transmission rate of Digital Subscriber Lines (DSL(s)) (21,22) in a binder group (25). The DSL(s) in the binder group are monitored to determine their actual transmission rate. The allowable transmission rate of individual DSL(s) is adjusted in order to make sure that it does not exceed some target level, but that in case many lines are inactive or in a keep-alive mode, that the transmission rate of the active lines can be substantially higher than the transmission rate based on all lines being active and transmitting at their maximum rate. Avantageously, the actual throughput for the binder group can be increased substantially above that allowed for a static assignment of transmission rates.

Abstract: A system and method that provides lifeline service to DSL customers (20-23) when a loss-of-power message is sent to the central office (24) from an integrated access device (50-53) on the customer premise. If a predetermined number of loss-of-power messages are received then power is provided to the integrated access device from the central office. To this end, a power supply (100) at the central office provides power through an isolator circuit (102) to a relay (106). The relay is connected through to the twisted pair (48) to the integrated access device. The data connection may also be powered in this manner or, in order to save further wattage, the data connection may be disconnected for the duration of the power outage.

Abstract: Metallic testing of a subscriber loop (223) that provides voice and DSL services is provided by a voice switch (200) and DSL services (202), each of which includes a metallic test unit (208, 258). A voice line card (204) has a connection to a first metallic test bus (210) connected to the voice switch metallic test unit (208) via a first relay set (220, 222) configured to connect the metallic test bus to the subscriber loop and to disconnect the subscriber loop from the line card during testing. The DSL line card (240) has a connection to a second metallic test bus (260), which is also connected to the DSLAM metallic test unit (258), and to the subscriber loop. A second set of relays (250, 252) control the connection of the metallic test bus to the line card to the subscriber loop. A signal is sent from either metallic test unit to cause the relays to change to provide a clear path for metallic testing from DC to light.

Abstract: A communication system and method for allocating overhead voltage between a telephonic switch and a user device is described. A line driver is located in the telephonic switch and is coupled to the user device. The line driver is in one of a plurality of communication states. A processor, coupled to the line driver, allocates the overhead voltage in response to the communication state of the line driver.

Abstract: A method and system for determining the high speed data service capability of a subscriber line includes sending an embedded test signal to a subscriber line. A reflected signal received in response to the test signal is analyzed for determining transnussion characteristics of the subscriber line. Based on the reflected signal, a determination about the high speed data service capabilities of the subscrib er line is made and stored for future reference.
