    摘要: An integrated communication system (e.g., BIGFON) includes the narrow-band telephone network and a superposed video-telephone network. The path search for setting up calls in the telephone network is carried out with the aid of the telephone call numbers. To permit a video-telephone network structure independent of the structure of the telephone network, each subscriber of the video-telephone network must be assigned a separate video-telephone call number for the path search in the broadband network. In order that a subscriber does not have to dial two different numbers to set up a video-telephone call, each exchange (V1, V2) of the communication system includes a mapping circuit (ZS) which establishes for each video-telephone subscriber (TEA, TEB) a correspondence between his or her telephone call number and a video-telephone call number serving to set up calls in the video-telephone network. This video-telephone call number can be called up from the mapping circuit (ZS) via the telephone network (FN).

    摘要: When an ONU accommodating range is enlarged, and ONUs shorter and ONUs longer in a communication path to an OLT are accommodated in a PON at the same time, there is a need to change a light intensity at the time of transmitting a downstream signal in order that both of the ONUs receive a downstream signal from the OLT. When a near-end ONU receives a signal having a light intensity necessary to communicate between the OLT and a far-end ONU, there arises such a problem that the light intensity is as high as an ONU receiver fails. In order to eliminate the ONU failure of the above problem, prior to transmission of the downstream signal, a downstream signal transmission schedule (downstream light intensity map) is notified to all of the ONUs. An optical transceiver of the OLT has a function of adjusting an output light intensity, and adjusts the light intensity to values receivable by the individual ONUs when the signal arrives at the respective ONUs according to route distances to the respective ONUs.

    摘要: Techniques described use Generic Framing Procedure (GFP) to transport data across an optical transport network between near and far Fiber Channel (FC) or Fiber Connectivity (FICON) local area optical networks. Each FC/FICON edge node (FCE) on an edge of the optical transport network has multiple modes for processing FC/FICON frames transported across the optical transport network. The techniques include receiving, at a near FCE from a far FCE, a GFP control plane message that includes a mode field that holds data that indicates a far mode, wherein the far mode is used at the far FCE. It is determined whether a near mode used by the near FCE matches the far mode based on the mode field. If it is determined that they do not match, then an alert is caused. These techniques allow software to utilize existing GFP chips in FCE that use optional processing, such as distance extension.

    摘要: An apparatus and a method for forwarding data packets through a fiber optic ring network includes forwarding data packets on a packet by packet basis. A node on the fiber optic ring network decides on a packet by packet basis whether to transmit on the working or protection path. Because this decision is being made on a packet level, reservation of throughput resources no longer is made at a one to one ratio. Rather, protection path resources are reserved at a ratio significantly less than one to one. In one embodiment, no resources are reserved for path restoration or protection path routing. Rather, quality of service provisioning is used to resolve interference situations wherein instantaneous demand exceeds capacity. A node evaluates ring conditions in relation to the demand of traffic resources and the relative quality of service ratings to determine whether and how to forward a packet. Additionally, a node decides whether to use the working or protection path by considering the final destination on the fiber optic ring network, any identified ring conditions and, in some embodiments, quality of service. The ring conditions to which the inventive nodes respond include OSI layer 1, layer 2 and layer 3 conditions.

    摘要: An Asynchronous Transfer Mode (ATM)-based distributed virtual tandem switching system is provided in which a network of ATM-based devices is combined to create a distributed virtual tandem switch. The system includes an ATM switching network that dynamically sets up individual switched virtual connections. The system also includes a trunk interworking function (T-IWF) device and a centralized control and signaling interworking function (CS-IWF) device. The trunk interworking function device converts end office voice trunks from TDM channels to ATM cells by employing a structured circuit emulation service. The centralized control and signaling interworking function device performs call control functions and interfaces narrowband signaling and broadband signaling for call processing and control within the ATM switching network. Consequently, the ATM based distributed virtual tandem switching system replaces a standard tandem switch in the PSTN.

    摘要: A method for providing secure communications through a communications network comprising ATM channels and TDM channels. The communications network includes at least one closed user group of network elements configured to communicate with only other network elements in the closed user group. The method receives a connection setup request at an ingress ATM switch, via a UNI attached to the ATM switch, in response to a call initiated through a TDM channel. The UNI interfaces a first network element of the closed user group with the ATM switch. The method further verifies that an ATM End System Address (AESA) contained in calling party information of the connection setup request is consistent with the attached UNI. Additionally, the method establishes a connection with at least a second network element of the closed user group through an egress ATM switch in the communications network when the AESA is consistent with the attached UNI.
