    摘要： A system includes a customer network and a telephony server. The customer network is associated with an independent carrier (IC), a native carrier, or both. The customer network includes a call manager, a telephone gateway, an internet gateway, a first device associated with the IC, and a second device associated with the native carrier. The first device communicates with the telephone gateway via the call manager. The second device communicates with the internet gateway. The telephony server is associated with the native carrier. The telephony server supports traffic from the first device and the second device. The telephony server includes a PBX and a session border controller (SBC). The SBC communicates with the telephone gateway via a session initiation protocol (SIP) trunk.

    摘要： A clock generating circuit generates a clock of a rate corresponding to a Dch rate in response to a specification from the exterior. A counting circuit detects completion of reception of one frame by counting the clock number up to null11null at timing at which a start bit detecting circuit detects a start bit in a serial signal. An S/P converting circuit fetches a serial Dch signal bit by bit in synchronism with the clock, outputs the latest fetched 10 bits in a parallel form and latches eight bits of a real data portion among the output data into a latch circuit at the time when reception of one frame is completed. In parallel with the above operation, a parity calculating circuit and flag/interruption generating circuit set various flags and generate a reception completion interruption.

    摘要： A CPU calls in accordance with a MW call-back request one of MW call-back candidates registered in a MW call-back candidate memory region to correspond to a called extension terminal issuing a MW call-back request. When a plurality of MW call-back candidates are registered to correspond to the called terminal, one of the MW call-back candidate terminals which corresponds to one of the count values stored in the count value memory region, which corresponds to the requesting terminal issuing the MW call-back request, is determined as destination terminal. When no response to the MW call-back is obtained, the CPU changes the destination terminal to be called back the next by the same requesting terminal by changing the count values of the MW call-back candidates, which are provided to correspond to the requesting terminal.

    摘要： A multi-line key telephone system not having a key service unit includes three analog telephone lines to which up to eight, three-line telephones may be connected to provide enhanced service features with cost-effectiveness. System reliability is maintained, notwithstanding the power dependency of the telephones, by including POTS telephones to provide uninterrupted essential telephone service in the event of a power outage. Both data and voice communications between two or more of the three-line telephones is achieved by converting an input digital bit stream from either a digital or analog source into a corresponding out-of-band binary FSK radio frequency output signal that is transceivingly communicated between the three-line telephones as data packets within a TDM frame. The out-of-band signal thus permits analog voice communications on the same line to proceed without interference. A telephone initiating a communications session acts as a master station, establishing inter-station communications synchronous at the frame level and asynchronous at the packet level. The called telephone functions as a slave station in a second time slot synchronized to a first time slot in the TDM frame received from the master. Temporary storage of data in firmware buffers and controlled timing at both the master and slave permits these stations to function within their respective TDM frame time slots.

    摘要： A communication terminal connected to an analog telephone network and has a function for transmitting an incoming call signal with originator identification data inserted. Notification of an incoming call is stopped during a time period from the detection of a first ringing signal of the incoming call signal to the detection of the originator identification data. A user is notified of the presence of the incoming call is notified after the originator identification data is detected and notified to the user.
