Abstract: PROBLEM TO BE SOLVED: To improve a digital compatible plain old telephone service channel card and a method for using the same, which does not need additional devices, such as a divider or the like, when a digital subscriber's line(XDSL) service is provided in a plain old telephone service(POTS) telephone channel. SOLUTION: The digital compatible plain old telephone service channel card comprises a low-pass filter 246 and constituted, so that a digital subscriber line(XDSL) compatible 'plain old telephone service'(POTS) channel card interfaces a subscriber in a two-wire type subscriber's line and a communication exchange system; and a channel card 238 is connected to the subscriber's line and to process to filter a DSL signal, a channel support circuit 244 constituted to supply a power to the subscriber's line; a codec unit 242 for converting an analog signal from the subscriber's line to a digital signal and a digital signal from the communication exchange system to an analog signal to the subscriber's line; and a digital signal processor 240 connected between the codec 242 and the exchange system and constituted to give the appearance of a terminal end of the POTS service to the subscriber's line and the exchange system.

Abstract: PROBLEM TO BE SOLVED: To attain direct interconnection between a packet transport system and a setup channel type line interface unit in an intensive communication network and a pure packet type communication network. SOLUTION: An edge vehicle 140 is connected to an existing main wiring board 110. Respective subscriber lines 171, 173, 175 from the main wiring board 110 are terminated by an access shelf in the edge vehicle 140. An incoming twisted pair loop traffic is converted into an asynchronous packet traffic and given to a data subsystem 144 of the edge vehicle 140. The data subsystem 144 receives packet-processed data from the respective subscriber lines 171, 173, 175, and the data are transferred to a packet data transport network 150 or an end destination (final destination) in a conventional PSTN 160.

Abstract: A communications for interconnecting standard twisted pair loop subscriber lines to a packet network without traditional local digital switches. The packet transport edge vehicle comprises a plurality of access shelves including means for converting synchronous traffic to asynchronous traffic within each line interface circuit. The converted traffic is delivered via high speed packet data links to a data subsystem where the packets are routed to an appropriate end destination either in a packet data network, such as the internet, or to the traditional public switched telephone network.

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.
