A constant bit rate (CBR) traffic segmentation and reassembly apparatus and method are provided, in which an operation for converting CBR traffic included in a T1/E1 frame into an ATM cell and a reverse operation thereof, namely, an operation for converting an ATM cell into CBR traffic and carrying the CBR traffic in a T1/E1 frame are carried out. A standardized and simple status transition is thereby obtained. Accordingly, it is possible to accommodate an increased number of T1/E1 connections. The apparatus of the present invention can also be operatively connected to an ATM switch such as an ATM transceiver. It is thus possible to replace, with the ATM switch, audio switches of a conventional time division multiplex system configured to spatially and temporally exchange PCM data.
