    Abstract: A critical assured service that includes a network management system and an A/B switch. The A/B switch having at least four ports with a first port being connected to the network management system over a dedicated line. The A/B switch sending and receiving messages and/or signals from the network management system over the first dedicated line. The A/B switch automatically switching telephone service from a first point of presence to a second point of presence after the A/B is signaled that the first point of service is inoperable.

    Abstract: A system and method are presented for providing a telephone service. An analog signal is received from a telephone and the analog signal is converted into a digital signal in a first format. A modem is provided for receiving the digital signal in the first format. A digitizer is also provided for receiving the analog signal from the telephone. The system, in a first mode of operation, couples the digital signal in the first format to the modem, and in a second mode of operation, couples the analog signal from the telephone to the digitizer. The second mode of operation may be, for example, a power failure mode of operation.

    Abstract: A network device with a configurable interface. The device has at least two communication ports. An interface in communication with the ports is configurable as to the network layer, or layer 2 and 3, and the physical layer, or layer 1. The interface includes at least two lines for transmitting data and two lines for receiving data and a processor that determines the data transmitted and received. The processor controls the data in accordance with the configuration parameters of the interface, which are each independently selectable.

    Abstract: An electronic feeding bridge for a telephone line uses a two-stage circuit to provide high a.c. impedance between the load and the line and between the line and the load. The first stage includes one NPN type transistor and one PNP type transistor with their bases coupled together by a capacitor. The second stage includes one PNP type transistor and one NPN type transistor with their bases coupled together by a capacitor. The emitters of the transistors of the first stage are connected to the emitters of the transistors of the second through of a pair of resistors. The collectors of the second stage are connected to the load through of a pair of diodes, and the collectors of the transistors of the first stage are connected directly to the line.
