摘要： A packet switching apparatus is constructed by a basic module disposed in the apparatus casing and an additional module disposed on the outside of the apparatus casing. The basic module has a common processing function irrespective of an access method and a service type, an interface accommodating lines to be connected to the Internet, and a plurality of interface boards conformed to a specific access method by which a hardware scale may be small. Only the basic module functions as a packet switching apparatus, and a processing function peculiar to each access method and service type is executed by the additional module.

摘要： According to this invention, a digital key telephone system connected to an analog public network NW having a function of transmitting a ringing signal including identification information of a calling line through a subscriber line (CO line), accommodating a plurality of extension lines each connected to a digital key telephone (DKT) 2 or a standard telephone (STT) 4 as an extension terminal, and having a function of switching and connecting the subscriber line to the plurality of extension lines or the extension lines to each other includes a called party storage means storing, in advance, information representing the correlation between the calling line and the extension terminals 2 and 4 as a called terminal. When a ringing signal arrives from the analog communication network NW, calling line identification information (caller ID) contained in the ringing signal is detected by a calling line identification information interface unit (RCIU) 12. A control unit (RCTU) 16 determines the called extension terminal on the basis of the detected caller ID and the information stored in the storage means, so the extension terminal receives the call from the digital key telephone interface unit (RDKU) 13 or a standard telephone interface unit (RSTU) 15.

摘要： A method for reducing disturbing effects of coupling between a first transmission/reception device and a second transmission/reception device that are each connected to a subscriber line. According to the method, a signal received on a reception path of the first device is delayed by a delay equal to p times the transmission period. A coupling signal relating to a transmission path of a second device and the reception path of the first device is estimated based on a signal transmitted over the transmission path of the second device, and the delayed signal is ridded of the estimated coupling signal. Additionally, a device for transmitting/receiving a signal is provided. The device includes a memory coupled to a reception path for temporarily storing p symbols, a subtraction circuit, and a coupling estimation block. The coupling estimation block includes an adaptive filter with n (n>p) coupling coefficients and an estimation circuit that receives an ancillary transmission signal of another transmission/reception device. The estimation circuit and adaptive filter successively determine the n coupling coefficients as a function of the ancillary transmission signal and sum the coupling coefficients successively so as to deliver a coupling signal that is representative of estimated coupling between the reception path and the transmission path of the other device. The subtraction circuit receives an output of the memory and an output of the coupling estimation block.

摘要： In a telecommunication system comprising a telephone exchange (LE), an access node (AN) connected to the telephone exchange via a standard V5 interface and a data network (DN), a procedure for setting up a direct data connection between the access node and the data network from a terminal device. According to the invention, a data network subscriber is created in the access node (AN), and when the data network subscriber starts call setup, this is not signalled to the local exchange (LE) according to the normal V5 practice. The data network subscriber's call setup request is handled locally in the access node, where also a dial tone is generated for the data network subscriber. A data connection between the data network subscriber and the data network is set up directly from the access node on the basis of the dialling given by the data network subscriber.

摘要： An arrangement and a method provide access between a number of user stations connected by radio via a number of radio base stations and a switching arrangement of a telecommunication network. At least one access network is provided, and it connects to the switching arrangement over at least one interface. A radio access network including a number of base stations is provided which also includes the access network. An address field of an addressing mechanism of the interface between the access network and the switching arrangement is so structured that it includes a first part for addressing base stations and a second part for addressing/identifying selected bearer channels on the existing interface.

摘要： According to this invention, a digital key telephone system connected to an analog public network NW having a function of transmitting a ringing signal including identification information of a calling line through a subscriber line (CO line), accommodating a plurality of extension lines each connected to a digital key telephone (DKT) 2 or a standard telephone (STT) 4 as an extension terminal, and having a function of switching and connecting the subscriber line to the plurality of extension lines or the extension lines to each other includes a called party storage means storing, in advance, information representing the correlation between the calling line and the extension terminals 2 and 4 as a called terminal. When a ringing signal arrives from the analog communication network NW, calling line identification information (caller ID) contained in the ringing signal is detected by a calling line identification information interface unit (RCIU) 12. A control unit (RCTU) 16 determines the called extension terminal on the basis of the detected caller ID and the information stored in the storage means, so the extension terminal receives the call from the digital key telephone interface unit (RDKU) 13 or a standard telephone interface unit (RSTU) 15.
