    Abstract: A Mobile Switching Center (MSC) includes a cellular modem pool that comprises a number of pairs of modems in which the data terminal equipment (DTE) ports of each modem pair are cross-connected in a "back-to-back" fashion. This allows the two modems of each pair to interchange data via their DTE ports and thereby isolate that portion of a cellular fax call over the cellular communications channel from that portion of the cellular fax call through the PSTN. Fax information is transmitted over the PSTN-portion of the cellular fax call using a "1-D" fax compression scheme. However, fax information is transmitted over the cellular-portion of the cellular fax call using a "2-D" fax compression scheme and a data modulation as specified in AT&T Paradyne's "Enhanced Throughput Cellular" (ETC) Protocol. The fax terminal equipment at the cellular end of the cellular fax call is configured to perform fax compression/decompression using the "2-D" fax compression scheme. The PSTN-side modem of the cellular modem pool performs the translation between the "2-D" and "1-D" fax compression schemes transmitted on the cellular-side and PSTN-side, respectively.

    Abstract translation: 移动交换中心（MSC）包括蜂窝调制解调器池，其包括多对调制解调器，其中每个调制解调器对的数据终端设备（DTE）端口以“背对背”方式交叉连接。 这允许每对的两个调制解调器通过其DTE端口互换数据，从而通过蜂窝通信信道将该部分蜂窝传真呼叫与通过PSTN的蜂窝传真呼叫的该部分隔离。 传真信息通过“1-D”传真压缩方案通过蜂窝传真呼叫的PSTN部分传输。 然而，使用AT＆T Paradyne的“增强型吞吐量蜂窝”（ETC）协议中规定的“2-D”传真压缩方案和数据调制，通过蜂窝传真呼叫的蜂窝部分传送传真信息。 在蜂窝传真呼叫的蜂窝端的传真终端设备被配置为使用“2-D”传真压缩方案来执行传真压缩/解压缩。 蜂窝调制解调器池的PSTN侧调制解调器分别在蜂窝侧和PSTN侧发送的“2-D”和“1-D”传真压缩方案之间进行转换。

    Abstract: In recording a received image in an image communication apparatus, there is discriminated whether the received image is to be recorded as a color image or as a monochromatic image, then determined is which of plural cartridges is to be used according to the result of discrimination, and the received image is recorded with thus determined cartridge. In the apparatus capable of color and monochromatic image recording, it is thus made possible to reduce the overall cost and the electric power consumption, and to facilitate the maintenance.

    Abstract: In a color facsimile apparatus, a color scanner converts an original image into color image data, and a transmitter transmits the color image data in either a color transmission mode or a monochromatic transmission mode. A processor processes the color image data as processed color image data or processed monochrome image data according to the transmission mode of the transmitter. The data is displayed on a monitor, prior to transmission, in a first mode as a monochrome image and in a second mode as a color image.

    Abstract: Communication system and method including a calling apparatus and a called apparatus. The system comprises handshake means for exchanging negotiation information including error correction ECM capabilities data, contained in a plurality of command frames between the calling apparatus and the called apparatus. The system further includes means for initiating an error correction operation, a transmitter for transmitting and receiving between the calling and the called apparatus a data set having associated data frame identification information, and verification means for verifying receipt of the data set. A method corresponding to the system also is described.
