Patent number: 6937625Abstract: A method and device is described for converting an STM-1 signal into a sub-STM-1 signal in synchronous radio transmission. The invention provides for the use of a pure regenerator network element without any multiplexing function. The method according to the invention provides in transmission, for reducing the received STM-1 signal by one third (only the first TUG-3 is considered as valid and is transmitted in the radio link, whereas the second and the third TUG-3 are considered in an unequipped condition and are not transmitted), thus maintaining the STM-1 structure. In reception, the method provides for reconstructing the signal with the complete regenaration of the payload and the correct structure of the AU-4 without incurring any parity control infringement.Type: GrantFiled: December 21, 2000Date of Patent: August 30, 2005Assignee: AlcatelInventors: Claudio Colombo, Primo Garofoli, Giuseppa Licata, Alberto Lometti

Patent number: 6683890Abstract: A method and circuit are described for improving the pointer processing in the case of synchronous digital hierarchy (SDH) or synchronous optical network (SONET) transmission frames with VC4_4c, VC4_16c and VC4_64c concatenated payloads. The technique proposed by the existing Standards provides for two different state diagrams to be used in the pointer processing algorithm. One state diagram is used in the case of a concatenated payload and the other state diagram is used in the case of a non-concatenated payload. However, no solution is disclosed for automatically going from the states of one diagram to the states of the other diagram. The present invention provides a circuit so constructed that it can be used in an apparatus processing STM-4, STM-16 and STM-64 frames, through which the automatic recognition of the VC4-4c, VC4-16c and VC4-64c payload concatenation can be achieved. Therefore, it is not necessary to configure in advance the concatenation or non-concatenation condition.Type: GrantFiled: November 2, 1999Date of Patent: January 27, 2004Assignee: AlcatelInventors: Alessandra Rossi, Alberto Lometti, Luca Razzetti, Giovanni Traverso, Alberto Bellato, Sergio Cabrini, Claudio Girardi

Patent number: 6647519Abstract: A method and circuit for mismatch detection in SDH-coded frame trace identifiers within a telecommunication network, wherein received trace identifiers are compared with expected trace identifiers in determined locations of the communication network, to detect if a misconnection event has occurred and generate a corresponding alarm signal. The method comprises the steps of: a) validating the received trace identifier (TI) and issuing a corresponding validation signal (CRC7, CNST); b) comparing the received trace identifier (TI) with an expected trace identifier (ETI) and issuing a corresponding validation signal (MTC1, MTC16); c) evaluating the validation signal (CRC7, CNST) and the match signal (MTC1, MTC16); and d) generating a matching state signal (SVAL1, SVAL16) according to the result of the evaluation as per step c), wherein steps a) and b) are executed in parallel.Type: GrantFiled: October 12, 2000Date of Patent: November 11, 2003Assignee: AlcatelInventors: Alberto Lometti, Luca Razzetti, Giovanni Traverso, Roberto Cardillo

Patent number: 5777998Abstract: The invention relates to a method and circuit arrangement for the realization of the Higher Path Adaptation (HPA) function in Synchronous Digital Hierarchy (SDH) equipment. Such function serves to equalize frequency difference between the synchronisms of signals coming from different nodes of the network. The equalization is carried out through the use of the positive and negative justification technique. The invention, through the alteration of the justification instants, is capable of reducing the capacity of the elastic storage and the generated wander.Type: GrantFiled: November 23, 1994Date of Patent: July 7, 1998Assignee: Alcatel N.V.Inventors: Giovanni Traverso, Silvano Frigerio, Alberto Lometti
