摘要:
An image communication apparatus comprises a connection unit for connecting an external terminal, an image communication unit for conducting image communication, a switching unit for selectively connecting a line to said connection unit and said image communication unit, a first detection unit for detecting a calling signal from said line, a second detection unit for detecting a signal relating to the image communication, a third detection unit for detecting a signal relating to data communication, and a control unit for controlling said switching unit in response to the detection by said first, second and third detection units.
摘要:
L'appareil de communication (1) est connecté à une ligne de télécommunication (12) et détecte si un téléphone (11) connecté en parallèle est décroché. Dans ce cas l'appareil (1) détecte si un signal d'appel de télécopie est présent sur ladite ligne (12) ou si celle-ci est silencieuse pendant un certain temps, pour indiquer s'il se produit sur la ligne (12) un envoi/réception d'un signal d'image. L'appareil (1) peut donc substituer en priorité la réception/transmission du signal d'image sur la ligne (12) à un appel téléphonique (2) qui est présent sur cette même ligne (12), même si le téléphone (11) qui est connecté en parallèle avec cet appareil (1) est en activité.
摘要:
A data communication apparatus comprises a first switching means which switches over between data communication and speech communication depending as whether or not a signal indicating data communication mode is received within a predetermined period of time, a second switching means which switches over between data communication and speech communication depending as whether or not a response signal to a procedure signal is received in a predetermined period of time, detecting means for detecting a state of the apparatus, and selecting means for selecting one of the first and second switching means.
摘要:
Arrangement for optionally connecting a facsimile device (3, fig 2) or a telephone set (2, fig 2) to a subscriber line (1, fig 2) depending on the incoming call being a facs call or a telephone call. The arrangement is provided with selection means (3, fig 1), offering the choice between two operating states. In a first operating state an incoming call is always switched to the telephone set (2, fig 2) (telephone priority) unless the arrangement detects (5, fig 1) telefacs signals or a prescribed (4, fig 1) voice word ("fax"). In a second operating state the incoming call is always switched through to the facsimile device unless a prescribed (6, fig 1) voice word ("telephone") is detected (7, fig 1) (fax priority).
摘要:
A facsimile apparatus with a handset comprises a handset for speech communication (108), a current sensor (14a) for detecting a facsimile signal, and a three-wire curled cord (21a). An impedance balance of a terminal T3 and a terminal T4 is attained by utilizing return lines (32 - W1) of the current sensor (14a) and the curled cord (2a).
摘要:
A facsimile system with the body thereof usable as a subunit of a cordless telephone is disclosed. A parent unit (502) is connected to the telephone line. A facsimile subunit (508) is connected by radio to the parent unit. A telephone subunit (504) is also connected by radio to the parent unit. A circuit (11) included in the parent unit detects a signal indicating that the other party is in facsimile transmission mode. When a call signal is detected from the telephone line, the parent unit connects the line. When a CNG signal is detected, on the other hand, the parent unit connects the facsimile subunit by radio. In the case where a CNG signal is not detected, the parent unit starts the ring-up tone on the telephone subunit. An AGC circuit (1101) and a voice mute circuit (1701) are included in the parent unit.
