Abstract

In einer Telekommunikationseinrichtung sind eine digitale Teilnehmervermittlungsstelle (LE) mit mindestens einem Teilnehmerzugangsknoten (AN) sowohl für ISDN als auch analoge Teilnehmeranschlüsse über eine Schnittstelle (V.5.2) verbunden, bei der die Nutzkanäle in einem System von Basiskanälen (TS 1, TS 2,... TS n) mit einer festen Basisdatenrate (rb) angeordnet sind. Aufgabe der Erfindung ist es, Mittel für eine höhere Nutzung der Übertragungskapazität an der Schnittstelle (V.5.2) unter Beibehaltung der Kompatibilität zu bestehenden Standards aufzuzeigen, um den Konzentrationsfaktor an der Schnittstelle zu erhöhen. Die Aufgabe wird mit Hilfe einer Spracherkennungseinrichtung (V-REC) gelöst, welche Sprachsignale in den Nutzkanälen erkennt und Signalwandler (C1, C2) zum Komprimieren der Sprachsignale aktiviert, um mehreren Nutzkanälen mit Sprachsignalen gemeinsam einen Basiskanal zuzuweisen.
