Abstract
Abstract A data communication apparatus in which if it is determined that a distant station presently in communication is a called station by a distant-station discriminating means, and a call-waiting signal is detected by a call-waiting-signal detecting means, a call-waiting-telephone controlling means is activated. This call-waiting-telephone controlling means switches over the line to the interrupting-station side by controlling a line switching means, and commences processing for an interrupt communication by a call-waiting telephone. Thereby, even if there has been an interrupt request signal, an interrupt communication is not allowed if a distant station presently in communication is in a chargeable state.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
77 words
A data communication apparatus comprising: distant-station discriminating means for discriminating whether or not a distant station presently in communication is a called station; interrupt-request-signal detecting means for detecting reception of an interrupt-request signal from an interrupting station during communication with the distant station; and interrupt-communication controlling means for executing an interrupt communication with the interrupting station, wherein the interrupt-communication controlling means is activated in response to outputs of the distant-station discriminating means and the interrupt-request-signal detecting means.
Claim 2
Dependent Claim
77 words
A data communication apparatus comprising: distant-station discriminating means for discriminating whether or not a distant station presently in communication is a called station; interrupt-request-signal detecting means for detecting reception of an interrupt-request signal from an interrupting station during communication with the distant station; and interrupt-communication controlling means for executing an interrupt communication with the interrupting station, wherein the interrupt-communication controlling means is activated in response to outputs of the distant-station discriminating means and the interrupt-request-signal detecting means.
Claim 3
Dependent Claim
29 words
A data communication apparatus as claimed in claim 1, wherein said interrupt-communication controlling means is activated when the distant station is the called station and the interrupt-request-signal is detected.
Claim 4
Dependent Claim
31 words
A data communication apparatus as claimed in claim 1, wherein said interrupt-request-signal detecting means is activated only when said distant-station discriminating means discriminates that the distant station is a called station.
Claim 5
Dependent Claim
87 words
A data communication apparatus as claimed in claim 1, further comprising: notifying means for notifying an occurrence of interruption to an operator, when the interrupt-request signal has been received; interrupt-communication instructing means for instructing to execute an interrupt communication with the interrupting station by the operator; and selecting means for selecting the activating of the interrupt-communication controlling means from on the basis of the outputs of the distant-station discriminating means and the interrupt-request-signal detecting means and on the basis of the instruction by the interrupt-communication instructing means.
