- ITU勧告V.34通信モードの通信機能が履行不可である通信端末装置において、V.34通信モードの通信機能が履行可能である通信端末装置への発呼時に、ANSam信号を検出せずに受信したDIS信号のBITに基づいて、ITU勧告V.8通信モードの能力の有無を検出する検出手段と、該検出手段によりV.8通信モードの能力が有ると検出した場合に、前記受信したDIS信号に対する応答として、所定時間の無音状態を生成するように制御する制御手段とを備えることを特徴とする通信端末装置。
- 前記制御手段は、受信したDIS信号に対して応答するまでの間に、前記所定時間の無音時間を設定することを特徴とする請求項1記載の通信端末装置。
- 前記制御手段は、1回目に受信したDIS信号に応答せずに、次に受信するDIS信号まで待機することを特徴とする請求項1記載の通信端末装置。
- IP網を介したファクシミリ通信を行うことを特徴とする請求項1乃至3のいずれかに記載の通信端末装置。
- ITU勧告V.34通信モードの通信機能が履行不可である送信側の通信端末装置と、V.34通信モードの通信機能が履行可能である通信端末装置との間で通信を行う通信システムにおいて、前記送信側の通信端末装置は、受信したDIS信号のBITに基づいて、ITU勧告V.8通信モードの能力の有無を検出する検出手段と、該検出手段によりV.8通信モードの能力が有ると検出した場合に、前記受信したDIS信号に対する応答として、所定時間の無音状態を生成するように制御する制御手段とを備えることを特徴とする通信システム。
