Abstract:
A packet pipe architecture is disclosed for an access network (100) (e.g., provides access to an IP, ATM or similar packet-based network (118) in order to convey packet data traffic), whereby the network interfaces (B.1, B.2) with the packet pipe (106) are standardized so that any packet pipe that satisfies the interface requirements can be utilized in the same access network (100). Also, the packet pipe (106) uses a packet-based protocol stack with Quality of Service provisions for service delivery instead of the conventional best effort service delivery functions used. Consequently, the packet pipe (106) and access network (100) are capable of providing all of the numerous services available with an IP, ATM or similar packet-based network layered architecture.
Abstract:
A common access platform which is based on a scalable distributed architecture with integrated data capabilities to support asynchronous transfer mode (ATM) and time division multiplex (TDM) traffic. The platform is capable of serving multiple remote terminals with a significant increase in ATM and TDM traffic capacities. Furthermore, the platform is expandable by connecting a primary bank which includes ATM and TDM fabrics with one or more secondary banks through one or more stackplane buses. The traffic capacity of the common access platform can be flexibly scaled up or down by adding or subtracting secondary banks from the platform. The stackplane bus provides modularity for interconnections between the primary and secondary banks (Fig. 1).

An integrated data centric network is provided that integrates voice, data and video services into a single network, defines user services by the end user by providing middleware to enable the end user to develop services and applications; and provides a carrier grade service with distributed networking and services.
Abstract:
The invention relates to the use of one transmission technology for both Home Access Network and Home Local Area Network. The technology that is used for this is IEEE 1394, which carries two DAVIC logical networks over the same physical bus. With this transmission technology a home user can simultaneously watch multiple movies, have a video conference and still have capacity available for internal and external services.
Abstract:
The invention concerns a method wherein, when setting up a connection (SETUP) launched by a component (KE, KS) with time division multiplexing, an information of specific destination of an ATM communication network (vpi, vci) is derived from a given signalling information (rnr, znr) and an ATM switching connection(SVC) is automatically set up in the ATM communication network (ATM-KN). After transparent signalling and useful data (si, ni) transmission by means of the switching (WV) connection set up, said ATM switching connection (SVC) is switched out again. Said method enables a more efficient exploitation of the ATM network (ATM-KN).
Abstract:
A cell bus (270), which reduces the number of conductors required to transfer data in a telecommunications switching fabric, contains a plurality of conductors, Data[X:0], for transmitting information. A cell bus interface (110) generates a cell bus frame that includes a plurality of words 'X' bits in length, of both data and control information that includes, in part, routing information for the data. As a result of encapsulating data and control information into a cell bus frame for transmission on the Data[X:0] conductors, the number of conductors required to transmit data is reduced. An asynchronous transfer mode (ATM) switching fabric (200), which includes a plurality of cell buses configures in a point to point fashion between a cell routing unit (CRU)/ATM filter bank interface unit (AFIU) (220, 240) and a plurality of optical line units (OLUs) is also disclosed.
Abstract:
A system (100) for providing virtual connections through an ATM interworking multiplexer (130, 140) on a call-by-call basis. A signaling processor (160) receives signaling for a call and selects the virtual connection for the call. The signaling processor (160) generates new signaling that identifies the selection and transfers the new signaling to the ATM interworking multiplexer (130, 140) that accepted the access connection for the call. The multiplexer (130, 140) converts user information from the access connection into ATM cells for transmission over the virtual connection in accord with the new signaling.
Abstract:
Um eine OAM-Einstellung (ETHOAM, ATM OAM, Ll OAM) einer providerseitigen Schnittstelle (PS) eines providerseitigen Netzwerkzugangssystems (PN), an welche ein kundenseitiges Netzwerkzugangssystem (KN) angeschlossen wird, zu konfigurieren, wird ein neuartiges Verfahren und eine Vorrichtung vorgeschlagen. Dabei wird providerseitig zunächst ein Anschliessen des kundenseitigen Netzwerkzugangssystems (KN) an die providerseitige Schnittstelle (PS) des provider- seitigen Netzwerkzugangssystems (PN) festgestellt. Zudem wird providerseitig zumindest ein Teil eines durch das kundensei- tige Netzwerkzugangssystem (KN) unterstützten Protokollstapels (EOl, EOA, AOl) ermittelt. Daraufhin wird eine weitere Vorgehensweise in Abhängigkeit von dem festgestellten Protokollstapel oder Teil des Protokollstapels aus einer Pluralität von weiteren Vorgehensweisen (Vl, V2, V3) ausgewählt. Die Pluralität der weiteren Vorgehensweisen (Vl, V2, V3) umfasst eine erste Vorgehensweise (Vl). Gemäss der ersten Vorgehensweise (Vl) wird zusätzlich festgestellt, ob das kundenseitige Netzwerkzugangssystem (KN) Ethernet OAM unterstützt, falls der durch das kundenseitige Netzwerkzu¬ gangssystem (KN) unterstützte Protokollstapel Ethernet über ATM (EOA) umfasst. Die providerseitige Schnittstelle (PS) wird dann für Ethernet OAM (ETHOAM) konfiguriert, falls das kundenseitige Netzwerkzugangssystem (KN) Ethernet OAM (ETHOAM) unterstützt. Die providerseitige Schnittstelle (PS) wird jedoch für ATM OAM konfiguriert wird, falls das kunden¬ seitige Netzwerkzugangssystem (KN) Ethernet OAM (ETHOAM) nicht unterstützt.
Abstract:
A transmission method together with multi pairs of lines modulates the information to be transmitted, and transmits the modulated signals to the receiving end through the multi pairs of lines, in which the transmitting spectrum of each sender of the multi pairs of lines comprises two parts. The first part is a frequency band which satisfies the bearing condition of the modulation method; and the second part is a frequency band which doesn't satisfy the bearing condition of the modulation method. A sender that transmits together with multi pairs of lines comprises a set of modulation devices and a set of transmitting devices, and a set of coding devices and a set of selecting-combining devices. A receiver that receives together with multi pairs of lines comprises a set of demodulation devices and a set of receiving devices, and a set of decoding devices and a set of deselecting-decombining devices. The present invention improves the combination transmission capacity of the multi pairs of lines.
