Abstract
A facsimile apparatus capable of executing a first protocol for identifying a modem type includes a unit for determining, on the basis of a signal received in accordance with the first protocol, whether polling reception is to be performed, and a unit for transmitting a digital transmission command signal according to a T.30 protocol in accordance with determination by the determination unit.
Claims17
A facsimile apparatus capable of executing a V.8 protocol for identifying a modem type, comprising:
- means for determining, on the basis of a signal received in accordance with the V.8 protocol, whether polling reception is to be performed;
- and
- means for transmitting a digital transmission command signal according to a T.30 protocol in accordance with determination by said determination means.
A facsimile apparatus capable of executing a first protocol for identifying a modem type, comprising:
- means for determining, on the basis of a signal received in accordance with the first protocol, whether polling reception is to be performed;
- and
- means for transmitting a digital transmission command signal according to a T.30 protocol in accordance with determination by said determination means,
- wherein the first protocol is a V.8 protocol, and said determination means determines on the basis of a JM signal whether polling reception is to be performed.
A facsimile machine capable of executing a V.8 protocol for identifying a modem type, comprising:
- detection means for detecting a presence/absence of polling transmission data;
- means for transmitting a signal of the V.8 protocol including information representing the presence of the polling transmission data, in accordance with detection by said detection means;
- and
- means for performing polling transmission upon reception of a digital transmission command signal of a T. 30 protocol.
A facsimile apparatus capable of executing a first protocol for identifying a modem type, comprising:
- detection means for detecting a presence/absence of polling transmission data;
- means for transmitting a signal of the first protocol including information representing the presence of the polling transmission data, in accordance with detection by said detection means;
- and
- means for performing polling transmission upon reception of a digital transmission command signal of a T.30 protocol,
- wherein the first protocol is a V.8 protocol, and the signal of the first protocol is a JM signal.
A facsimile communication method for executing a T.30 protocol after a first protocol for identifying a modem type is executed, comprising the steps of:
- notifying a presence/absence of polling transmission data in accordance with the first protocol;
- and
- performing polling communication while omitting transmission/reception of a digital identification signal of the T.30 protocol,
- wherein the first protocol is a V.8 protocol, and the presence/absence of the polling transmission data is notified by a JM signal.
A facsimile communication method for executing a T.30 protocol after a V.8 protocol for identifying a modem type is executed, comprising the steps of:
- notifying a presence/absence of polling transmission data in accordance with the V.8 protocol;
- and
- performing polling communication while omitting transmission/reception of a digital identification signal of a T.30 protocol.
A facsimile communication method for executing a T.30 protocol after a V.8 protocol for identifying a modem type is executed, comprising the steps of:
- notifying a presence/absence of polling transmission data in accordance with the V.8 protocol;
- and
- performing polling communication while omitting transmission/reception of a digital identification signal and a digital transmission command signal of a T. 30 protocol.
A facsimile communication method for performing polling communication after a V.8 protocol for identifying a modem type is executed, comprising the steps of:
- registering information associated with a facility of an apparatus of a partner station in advance;
- notifying a presence/absence of polling transmission data in accordance with the V.8 protocol;
- and
- transmitting a digital transmission command signal of a T. 30 protocol by using a fast data communication modem on the basis of the registered information, thereby performing polling communication.
