摘要： A telecommunication network establishes a telephone call from a first location that generates compressed voice packets to a second location. The telecommunication network includes a plurality of switches, a first interworking function ("IWF") coupled to the first location and coupled to a first switch of the plurality of switches, a second IWF coupled to the second location and coupled to a second switch of the plurality of switches, and a network database coupled to said first switch. When a telephone call is initiated from the first location, the first switch receives signaling information from the first location. The first switch then queries the network database based on the signaling information and determines whether the second location uses compressed voice packets based on the query. Finally, the first switch establishes a connection between the first IWF and the second IWF if it is determined that the second location uses compressed voice packets. The connection bypasses the plurality of switches, and therefore reduces tandeming in the network.

摘要： AAL2 mini packets are integrated directly onto the physical layer to provide serial data transmission using statistical multiplexing. This can be achieved by generating a plurality of frames of a predetermined size. A plurality of AAL2 variable length mini packets are then statistically multiplexed onto the plurality of frames. A pointer field is then inserted into each of the frames. The pointer field includes a pointer that delineates the starting place of the next full packet in the frame that includes the pointer field, a framing bit that forms a pattern with other framing bits, and a parity bit. The frames are then transmitted over a serial transmission line.

摘要： A system transmits compressed voice packets over ATM. The system receives a plurality of voice data units and an encoding rule for each voice data unit. A packet is formed from the received data units. The packet includes a header. The header includes the amount of data units in the packet, and the encoding rule for each packet. The packet is then placed in an ATM cell which is transmitted on an ATM virtual channel. The ATM cell includes at most one packet.

摘要： 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. This approach is an advancement over previous inventions that specified network architecture and terminal adapter requirements to provide a graceful transition from an STM network (for example the AT&T long distance network) to an ATM network. Prior art described how to emulate an STM network in the ATM domain, but did not permit for compression and silence elimination and, therefore, did not allow achieving efficiency gains.
摘要翻译：该提议概述了一种接口同步传输模式（STM）和异步传输模式（ATM）网络以及ATM网络以有效的方式传输语音，传真和语音频带数据呼叫的方法。与众所周知的ATM可变比特率（VBR）方法相比，该方案允许通过重新使用STM网络信令并利用标准的AAL-1型适配层（用于恒定咬率，CBR，服务）。我们使用低比特率编码算法，并通过标记不包含对话突发的单元来实现语音的附加压缩。本发明定义了STM到ATM接口的具体规则，包括所有的路由转换，并且识别必要的终端适配器（TA）和ATM交换机能力。这种方法比先前发明的具有特定网络架构和终端适配器要求的发明更为突出，以提供从STM网络（例如AT＆T长距离网络）到ATM网络的平滑过渡。现有技术描述了如何在ATM域中模拟STM网络，但是不允许消除压缩和静音，因此不能实现效率增益。
