（産業上の利用分野）
本発明は電子交換機の時分割スイッチ接続方式に関し、
特に異なる音声符号化方式のライン回路、トランク等を
収容した場合の接続方式に関する。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a time division switch connection system for electronic exchanges,
In particular, it relates to a connection system when accommodating line circuits, trunks, etc. of different audio encoding systems.

た。(Prior Art) Conventionally, this type of time-division switch connection system prohibits audio exchange connections between different audio encoding systems when line circuits, trunks, etc. of different audio encoding systems are accommodated.
（発明が解決しようとする問題点）
上述した従来の時分割スイッチ接続方式は、異なる音声
符号化方式間の接続を禁止していたので、例えば伝送路

殊品となる欠点がある。(Problems to be Solved by the Invention) The conventional time-division switch connection system described above prohibits connection between different audio encoding systems. In this case, the audio signal on the time division switch is 32K
Since it is an ADPCM system, it has the disadvantage that it cannot be connected to line circuits, trunks, etc. of the 64KPCM system, which is the standard voice encoding system for exchanges. In addition, if connection is absolutely necessary, if the line circuit, trunk, etc. is an analog interface, the analog signal must be converted to a 32KADPCM signal by the line circuit, trunk, etc., and standard line circuits, trunks, etc. It has the disadvantage that it cannot be used and is a special product.
また標準のデジタルインタフェースの場合には回線対応
に変換回路を設けて、６４ＫＰＣＭ信号を３２ＫＡＤＰ
ＣＭ信号に変換してから交換機とインタフェースする必
要があり、変換回路が回線対応に必要なので高価になる
という欠点もあった。In addition, in the case of a standard digital interface, a conversion circuit is installed to support the line, converting the 64KPCM signal to 32KADP.
It is necessary to convert it into a CM signal and then interface it with the exchange, and a conversion circuit is required to support the line, making it expensive.
