Abstract: An improved plain old telephone service (POTS) line card that may be direct ly connected to a customer line that is also connected to a digital subscriber line access module. A second order filter is added to the front end of the POTS line car d in order to attenuate XDSL signals and to lower its amplitude. A new digital signal processor (DSP) includes further low pass filtering functions, gain compensation, termination impedance compensation and balance network compensation to provide the prope r balanced network as is known in current POTS cards but not provided in curre nt XDSL services. This card may also be used alone, without a XDSL equipped lin e.

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 i n the telephonic switch and is coupled to the user device. The line driver is in o ne 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 system and method for transmitting communication signals between a telecommunication switch and to a network site on a network server via a communication network. The method comprises the steps of connecting the telecommunication switch to the network site via the communication network and establishing a point to point path between the telecommunication switch and the network site.

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 located at an other end of the communication link and testing the communication link with the test system after the call has been terminated at the telephonic equipment.

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: A method for determining the security level associated with transmissions in a telecommunications network includes means for alerting parties of the security status of the transmission. When a route interconnecting the parties includes an insecure link, an alert is provided so that the parties are aware of the insecure nature of the call before communications begin. Alternatively, the parties may elect to decline or alter content of the communications to preserve integrity.

Abstract: An improved plain old telephone service (POTS) line card (238) may be directly connected to a customer line that is also connected to a digital subscriber line access module. A second order filter (246) is added to the front end of the POTS line card in order to attenuate XDSL signals and to lower its amplitude. A new digital signal processor (240) (DSP) includes further low pass filtering functions (248), gain compensation (250), termination impedance compensation (254) and balance network compensation (252) to provide the proper balanced network as is known in current POTS cards but not provided in current XDSL services. This card may also be used alone, without a XDSL equipped line.
