    Abstract: A communicating apparatus having a plurality of ports to connect a plurality of communication lines comprises a memory to store information indicating whether the plurality of communication lines are extensions of a private branch network or not, a designating circuit to designate whether the communication is to be executed through said extensions or not, and a selector to select one of the plurality of ports in accordance with the result of the designation of the designating circuit and the contents of the memory. The memory stores information indicating whether the communication lines are ISDN lines or PSTN lines. The selector includes a call generating circuit for generating a call in the G4 facsimile mode when the selected communication line is an ISDN line and for generating a call in the G3 facsimile mode when it is decided that the partner is not a G4 facsimile apparatus after completion of the call generation.

    Abstract: In a terminal adapter which is located between a data terminal equipment unit (11) and a data communication network (12) and which includes a buffer memory (22, 27) for memorizing an original data signal sequence sent from each of the data terminal equipment unit and the data communication network, the original data signal sequence is subjected to data compression by a data compression circuit to be thereafter memorized into the buffer memory and to be read out of the buffer memory as a readout data signal sequence. The readout data signal sequence is expanded by a data expansion circuit (32, 35) to be sent to the data terminal equipment unit or the data communication network at a transmission rate matched therewith. The data compression may be executed by the use of an LZ method, a modified LZ method, such as LZW, LZSS, or the like.

    Abstract: The invention is an adaptor which permits using a digital telephone device with an incompatible telephone network access. In its most preferred embodiment, the present invention is an adaptor which permits an ISDN telephone device to exchange digital data with two Switched-56 Access. An ISDN Basic Rate Access interface circuit interfaces with the ISDN telephone device, while two Switched-56 Access interface circuit interfaces with two Switched-56 Access. The adaptor also includes a clock recovery circuit for synchronizing digital data transfers occurring between the ISDN Basic Rate Access interface circuit and the ISDN telephone device with the digital data transfers occurring between the Switched-56 Access interface circuit and the Switched-56 Access. In an alternative embodiment, the clock recovery circuit synchronizes digital data transfers between the ISDN Basic Rate Access interface circuit and the Switched-56 Access interface circuits rather than conversely as in the preferred embodiments so a Switched-56 telephone device may exchange digital data with an ISDN Basic Rate Access.

    Abstract: A PCM telephone switch that is simultaneously compatible with both DS-1 and CEPT PCM formats is disclosed. A switch module performs timeslot switching of individual subchannels between DS-1 and CEPT trunks which are input by way of digital group interfaces. Each group interface couples to one or more trunks of serial bit streams of either DS-1 or CEPT format standards. After the input serial bit stream is converted to a parallel format, it is used as eight bits of the address bits of data processing ROMs from which a corresponding 8-bit word is parallel read on a per channel basis and routed to the appropriate output data processing ROMs. The output data bits of the ROMs are the processed data bits which are reconverted to serial format for either DS-1 or CEPT standards as required by the output trunk. A-law or .mu.-law decoding and encoding is accomplished independently from input to output channel on a per channel basis.

    Abstract translation: 公开了同时兼容DS-1和CEPT PCM格式的PCM电话交换机。 交换机模块执行通过数字组接口输入的DS-1和CEPT中继线之间的各个子信道的时隙切换。 每个组接口耦合到DS-1或CEPT格式标准的一个或多个串行比特流中继线。 在将输入串行比特流转换为并行格式之后，将其用作数据处理ROM的地址位的8位，从每个通道开始对应的8位字并行读取，并路由到适当的输出数据 处理ROM。 ROM的输出数据位是被处理的数据位，根据输出中继线的要求，它们被转换为DS-1或CEPT标准的串行格式。 在每个通道的基础上，独立于输入到输出通道实现A律或μ-解码和编码。

    Abstract: A system and method are disclosed for adapting the rate of a data terminal equipment having a V-series type interface connected to an integrated services digital network which supports more than two simultaneous communications. A V.110 rate adapter is provided which receives user data at a user data rate from the data terminal equipment and outputs a bitstream containing the user data at a B-channel data rate. A fractional rate adapter is also provided which receives this bitstream and outputs a second bitstream at a lower subchannel data rate using a bit discarding technique.
