摘要： The present invention relates to an arrangement and a method for echo cancellation wherein only telecommunications traffic (s6) of a downlink (3), for which echo cancellation is performed, passes through an echo canceller function (1'). Traffic (s5) of an uplink (2) is forwarded via a switch (15) to a near end (B) without passing through the echo canceller function (1'). A signal copy (s9) of traffic (s5) of the uplink is created by the switch (15) and directed to the echo canceller function (1') in order to serve as a base for an estimated echo signal (e'). The estimated echo signal (e') is subtracted from the traffic (s6) of the downlink, which is input to the echo canceller function (1'), so as to create an output signal (s8), which is substantially free from echo. The invention makes it possible to reduce the processing capacity required in connection with echo cancellation and provides for a decreased delay of traffic of the uplink (2).

摘要： The present invnention relates to a coupling node (MG1) for coupling of communications in a telecommunication system, comprising networks (N1, N2) with different signal formats. The coupling node has switching and trunking functions (CP21, CP23) corrsponding to the signal formats, and telefunctions, e.g. coders/decoders (F21) and echo cancellers (F22), which the node can vouple into a communication by means of a selector (PS1). The functions are supported by printed board assemblies (CB1-CB9) in magazines (SR1), and th eprinted board assemblies have signal processors (DSP11-DSP13) with access points (SAP11-SAP14). The selector hunts one of the signal processors for handlingone of the functions. If the processor has sufficiently free memory space in its data store and in its instruction memory and sufficient processor capacity, this processor is selected. Otherwise a new processor is hunted which is investigated in the same way.

摘要： The present invention refers to a gateway (MGW1) in a telecommunication system (TS1) enabling connections to be effectively established between various networks (N1, N2, N3) in the telecommunication system. The gateway comprises resources from different nodes (RNC1, MSC1, IP1, VX1) of the various networks. Servers (S1-S6) from the networks are connected to the gateway (MGW1) and co-utilize the resources, which contributes to the effective utilization of the resources. This effective utilization of the resources is supported by the resources being divided into resource groups. Specific ones of these resource groups can be utilized by solely each one of the servers. Consequently, important services such as alarm services and security services can always reach the necessary resources in the gateway. Other resource groups can be co-utilized by only a small number of the servers while additional resource groups may be co-utilized by all of the servers (S1-6). By division into the resource groups the resources of the nodes (RNC1, MSC1, IP1, VX1) are co-utilized without the establishing of specific significant connections having to be rejected.

摘要： A media stream system (140) processes plural media streams (148), e.g., speech streams or speech channels. The system comprises plural processors (146), each of which execute one or more plural types of media stream processing functions (147), A switch function (144) routes packets of the plural media streams to a sequence of the plural processors whereby the plural types of media stream processing functions are sequentially performed relative to the packets. A packet size for the packets is chosen to minimize overhead load on at least one of the plural processors without causing undue delay for a packet awaiting by the at least one of the plural processors. In an example non-limiting implementation, the packet size for a packet of media information is chosen to be 160 octets, consecutive packets of a same media stream being separated by a packet repetition interval which is 20 milliseconds.

摘要： Asynchronous data samples are received from a plurality of data channels for distribution onto a plurality of data processors each having a plurality of processing-slots. The identity of channel from which a sample is received is determined using a channel ID associated with the sample. A time-stamp is assigned to at least one sample from each respective channel. Finally, at least one time-stamped sample is assigned to a processing-slot such that the separation between the time-stamp and a nearest time-stamp of at least one sample assigned to at least one other processing-slot of each respective processor is maximized.

摘要： The present invention relates to a coupling node (MG1) for coupling connections in a telecommunications system which includes networks (N1, N2) that have separate signal formats. The coupling node includes switch and trunk functions (CP21, CP23) corresponding to the signal formats and telecommunications functions, for instance encoder/decoder (F21) and echo canceller (F22), wherein the node can be coupled into a connection through the medium of a selector (PS1). The functions are carried by circuit boards (CB1-CB9) in magazines (SR1) and the circuit boards have signal processors (DSP11-DSP13) having access points (SAP11-SAP14). The functions have a hierarchically arranged address which denotes access points, processors, circuit boards and magazines. The internal communications resources (105, 160) of the coupling node (MG1) are used in a resource-saving manner by using the hierarchic address to interconnect two consecutive functions of said functions in a connection. On the basis of the address, the node is able to select speciments of the functions (CP21, CP23, F21, F22) that lie close together. Primarily, there are chosen the two functions that can be accessed via the same access point (SAP11), secondly the two functions that are found on the same signal processor (DSP11), thirdly those that lie on the same circuit board (CB1), and fourthly those that are found in the same magazine (SR1).
