2. Description of the Related Art In a conventional telephone, for example, 3.4.
It is connected to an analog line (analog line network) having a frequency band of kHz, and is in-channel, and call information (for example, "Hello" or the like) and control information (for example, the telephone number of the other party for performing call setting or the like) ( Hereinafter, it will be referred to as call control information). That is, as shown in FIG. 2, call information and call control information are transmitted without being physically or logically distinguished.

With the advent of videotex systems and voice mail systems due to advances in information processing technology, as a digital communication (line) network for integrating communication systems such as telephones and facsimiles into these systems. ISDN networks, for example, are becoming popular. The ISDN network transmits call information and call control information by an out-channel method. That is, in the ISDN network, as shown in FIG. 3, an information channel for transmitting call information (hereinafter referred to as B channel) and a signal channel for transmitting call control information (hereinafter referred to as D channel). Are logically separated.

Further, in the ISDN network, one line is composed of two B channels having a transmission rate of 64 kb / s and one D channel having a transmission rate of 16 kb / s, and therefore transmits call control information. Since the capacity of the D channel to be used is sufficiently large, in addition to the minimum necessary control information such as the other party's telephone number in the analog line network,
For example, the subscriber (telephone) number (caller number) of the caller,
Arbitrary information of a predetermined length (hereinafter referred to as user-to-user information) and the like can be transmitted as call control information.

The call control information is transmitted before the called party (the called party) answers.

[0006] In a telephone that can be connected to such an ISDN network, the telephone number of the calling party stored in advance in the built-in memory and the calling party transmitted by the D channel before the called party answers It has a function of responding only when the numbers match, so that it is possible to prevent a call from a recruiter, a mischievous call, or a wrong call.

[0007]

However, since the calling party number does not necessarily correspond to the individual calling party one by one, the calling party cannot prove that the calling party is who he / she is. Therefore, there is a problem that the called party can know the calling party number (subscriber number) of the calling party, but cannot determine who the call is from.

Therefore, personal authentication information for certifying the originator's individual such as a name and ID number is registered in advance in the caller side telephone and the callee side telephone, and from the caller side telephone, A method of transmitting this personal authentication information as user-to-user information and responding only when it matches the personal authentication information registered in advance on the telephone of the called party, or the calling party number and called party of the calling party Phone number registered in advance on the local phone (caller ID)
It is conceivable to make a response only when both the personal authentication information and the personal authentication information registered in advance on the receiver's telephone match.

However, when the caller tries to call a telephone connected to the ISDN network by a telephone connected to the analog circuit network at a place where he / she is out, for example, the telephone connected to the analog line network is ISDN D
Since it is not possible to send the caller ID and personal authentication information to the channel, this method has a problem that a telephone connected to the analog line network cannot make a call to a telephone connected to the ISDN network. It was

The present invention has been made in view of such a situation, and makes it possible to freely communicate from an analog line network to an ISDN network.
