  • Patent number: 6697353
    Abstract: This proposal outlines an approach for interfacing Synchronous Transfer Mode (STM) and Asynchronous Transfer Mode (ATM) networks and for transporting voice, fax and voice-band data calls by the ATM network in an efficient manner. In contrast to the well known ATM Variable Bit Rate (VBR) approach, this proposal allows one to transport 64 kb/s traffic efficiently over ATM by re-using STM network signaling and exploiting the standard AAL-1-type adaptation layer (intended for Constant Bite Rate, CBR, services). We use low bit rate encoding algorithms and achieve additional compression for speech by marking cells that do not contain talk spurts. The invention defines specific rules for STM-to-ATM interfacing, including all routing translation, and identifies necessary Terminal Adapter (TA) and ATM switch capabilities.

  • Patent number: 6324179
    Abstract: An Asynchronous Transfer Mode (ATM) network comprising a plurality of ATM switches may be arranged so that it receives calls from Synchronous Transfer Mode (STM) switches that employ in-band signaling by first converting in-band signals received from an STM switch to an out-of-band signaling message and then transmitting the message to the ATM switch that will route the associated call toward its destination. At an interface which interfaces the ATM switch with the out-of-band signaling network, the contents of the received message are converted to a form suitable for presentation to the ATM switch. For example, the identity of the trunk over which the call will be routed from the STM switch to the ATM switch is converted to a virtual channel identifier.

  • Patent number: 5894475
    Abstract: An ATM network which collects billing data from ATM switches in a switched voice network. A full, partial or summary report is produced. The ATM switches can be anywhere in the network. The ATM network includes the ATM switches, a data collection unit and billing systems. The data collection unit collects pertinent data and outputs the data to an AT&T billing system or any other desired billing system. Because ATM systems use cells for carrying information, the system is faster and more efficient than TDM systems. In addition, the output of the data collection system is table driven and can be defined to match the input needs of TDM billing systems without increased effort or expense.
