摘要:
Control means of an exchange comprising connection means for accommodating a telephone and the control means for controlling the accommodated telephone, receives a dial signal from the telephone without causing the telephone to respond to an incoming call when the telephone that is performing incoming call ringing is hooked off, causes the hooked-off telephone to respond to the incoming call when the received dial signal is a first dial signal, and causes the telephone as a call source to make a call without causing the hooked-off telephone to respond to the incoming call when the received dial signal is a second dial signal. Thereby, it is possible to make a call even during incoming call ringing.

A method and apparatus for enabling customer premise Public Branch eXchange (PBX) service feature processing to be performed in a service provider network are disclosed. For example, the method receives a signaling message associated with a user by an application server deployed in a communication network, and accesses a customer premise Internet Protocol (IP) Public Branch eXchange (PBX) to retrieve customer premise IP PBX based service logic and data associated with the user by the application server. The method forwards an updated signaling message by the application server to a Serving Call Session Control Function (S-CSCF) network element for completing a service feature associated with the service logic and data in the communication network.

The objective of the present invention is to provide a lower main device capable of connecting a non-IP terminal such as a digital terminal to an upper main device using an IP network and of accommodating call control. The lower main device behaves as one or more IP terminals toward the upper main device and houses one or more non-IP terminals which each correspond to the one or more IP terminals.

A telephone exchange system includes a connection interface connecting a communication line and a plurality of extension telephones, a database having a dial-in conversion table registering a received number in association with a number after conversion for a dial-in incoming call, and an extension number table registering an extension telephone in association with an extension number of the extension telephone, and a main controller connected to the connection interface and the database. When the dial-in incoming call comes from the communication line, the main controller retrieves an extension number which coincides with the received number from the extension number table. When there is an extension number which coincides with the received number, the main controller causes an extension telephone corresponding to the extension number to ring.

A telephone incoming call control unit 21B of a communication apparatus B 20B counts the total number of incoming calls and the number of incoming calls for each communication type indicating the breakdown of incoming call operations, as incoming call history data 21B for each telephone terminal B 30B as a slave unit, retrieves the incoming call history data 21B upon arrival of an incoming call from a certain calling party for the telephone terminal B 30B, extracts incoming call history data on the calling party from which the telephone terminal has received the incoming call, transmits the data to the telephone terminal when the telephone terminal is in an idle state, and causes an indicator 31B of the telephone terminal to display the data. The telephone incoming call control unit 21B thereafter transmits the call signal to the telephone terminal.

The present invention relates to a method wherein communication links between subscriber access lines of subscriber access units of an exchange in a switching system comprising a number of exchanges are established within the exchange concerned either directly in the respective subscriber access unit or between the subscriber access units connected by trunk lines directly to one another or via at least one subscriber access unit, without involving a central switching device of the exchange concerned, and under the control of the central controller belonging to this exchange.
摘要:
In accordance with the invention, an interface between an incumbent local exchange carrier's central office terminal and a competitive local exchange carrier's remote terminal is provided by an Integrated Services Digital Network interconnection. Such a connection provides two basic data channels of 64 Kbps each and at least one utility channel. The ISDN signal can be carried over a single wire pair. The interface may be used to interconnect one or two digital channels. The channel units may be designed to remove the robbed bits from the data channels and place them in the utility channels. Further, the utility channel may be employed to transmit frame phasing information so that the networks can synchronize their robbed bit signaling so that both networks use the same bit positions for robbed bit signaling thus minimizing data bandwidth reduction due to robbed bit signaling.

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.
