摘要： An arrangement for concentrating broadband data from a plurality of CPEs (customer premises equipments) for transmission over a link to an ATM network. Because each CPE can generate data at the full rate of the link, it is necessary to detect peaks of bursty traffic from a CPE user quickly and to limit the rate of data transmission whenever the capacity of the link may be exceeded. This is accomplished first by allowing the transmission of certain classes of traffic (lower priority) only when a token to permit transmission has been accumulated in the CPE, and second, by having a FIFO buffer for each user and detecting whenever the FIFO buffer has accumulated more than n cells; when this condition is detected, no more tokens are sent back to the user. The user is not allowed to accumulate more than m tokens. Advantageously, this arrangement allows essentially the full bandwidth of the link to the ATM network to be utilized by a timely throttling of bursts of traffic when they cannot be accommodated.

摘要： An arrangement for generating and receiving standard telecommunications network signals on behalf of a terminal not equipped to generate or receive such signals. A controller shared by a plurality of such terminals receives signals from these terminals over a permanent virtual circuit (PVC) and uses the information received over the PVC to perform signaling. In a specific embodiment, the terminals are set top boxes, connected to a video cable, for controlling television sets. The controller controls signaling for establishing connections between the set top box and a video vendor system, and tunes the set top box to receive signals on the proper channel. Advantageously, such an arrangement significantly reduces the cost of the set top box while still allowing for a highly flexible signaling arrangement to the video vendor system.
摘要翻译：一种用于生成和接收标准电信网络信号的装置，其代表不配备生成或接收这种信号的终端。由多个这样的终端共享的控制器通过永久虚拟电路（PVC）从这些终端接收信号，并使用通过PVC接收的信息来执行信令。在具体实施例中，端子是连接到视频电缆的机顶盒，用于控制电视机。控制器控制用于建立机顶盒和视频供应商系统之间的连接的信令，并且调谐机顶盒以在适当的信道上接收信号。有利地，这种布置显着地降低了机顶盒的成本，同时仍然允许对视频供应商系统的高度灵活的信令布置。

摘要： A method and apparatus are provided for transferring an ATM call. A first ATM call (124) is established between a first party (120) and a second party (116) and a second ATM call (128) is established between the second party (116) and a third party (118). The first and second ATM calls both include a plurality of segments (124a–d, 128a–d) or connections that are coupled to a plurality of ATM switches (208, 210, 212, 214) over ATM facilities to provide virtual connections. The transfer is accomplished by sending a message to the ATM switch over the ATM facility (109) to request the transfer of the first party to the third party. The message identifies the first ATM call and the second ATM call. The switch makes a new connection (220) between the first ATM call and the second ATM call and releases the segments of the first and second ATM calls that connect the ATM switch to the second party. As a result, the first party and the third party are connected for communication.

摘要： An ATM Packet Access Gateway (ATM PAG) system manages an ATM bearer path extending between ATM endpoints participating, for example, in a VoATM call. The system includes an ATM PAG having a first ATM bearer connection termination for terminating a first bearer connection with a first ATM endpoint, and a second ATM connection termination for terminating a second bearer connection with a second ATM endpoint. A call control entity is associated with the ATM PAG and communicates call control instructions thereto. The call control instructions include instructions for logically concatenating the first and second ATM bearer connections into an active ATM bearer path extending between the first ATM endpoint and the second ATM endpoint. A Media Access Gateway (MAG) function of the ATM PAG is responsible for establishing the connections that form the ATM bearer path. An ATM switch function of the ATM PAG moves bearer traffic ATM packet payloads over the active ATM bearer path.

摘要： A telephone switch-integrated modem pool and broadband access concentrator provide improved data network access through a PSTN local loop. Rather than simply cascading data as TDM traffic through the PSTN, plural switch-integrated modems, a broadband access concentrator, and a broadband pipe are used to route data traffic between local loop subscribers and one or more data network service providers. Advantageously, point-to-point connections are maintained between subscriber and service provider equipment in order to enable continued use of high level subscriber-provider protocol service negotiation (such as PAP/CHAP, NCP and the like). LCP (link layer) management and translation between the asynchronous subscriber-modem pool link and the synchronous provider-modem pool link are handled transparently by the broadband access concentrator.

摘要： A method for providing narrowband-related service features to subscribing broadband lines comprises establishing a composite voice path interconnecting a narrowband server and the subscribing broadband line via a broadband switching fabric. Particularly, a call set-up signal is received in a broadband call processor, converted to narrowband signaling format and extended to a designated narrowband server. Responsive to receipt of the call set-up signal, the designated narrowband server establishes a narrowband voice path interconnecting a narrowband network element to a synchronous-asynchronous converter. Subsequently, the broadband call processor establishes a broadband segment interconnecting the subscribing broadband line with the synchronous-asynchronous converter. The broadband segment corresponds to the narrowband voice path to form a composite voice path. The composite voice path is used by the designated narrowband server to provide narrowband-related service features to the subscribing broadband line. After a call in which narrowband-related features may be invoked has been disconnected, the composite voice path is released.

摘要： A system and method for delivering packetized data representing radio signals to and from cell sites, and to and from a destination point via a fast packet network. Each cell site includes an interface for packetizing the radio signals and transmitting the packetized data to its destination. The destination could be a delivery point at a switch connected to the telephone network, which then converts the packetized data into a form usable by the telephone network. Alternatively, the destination point could be another cell site, which then depacketizes the radio signal and retransmits the radio signal to another wireless communication device without connecting to the telephone network.
