| 摘要 |
The invention relates to a communications system in which communication terminals (KE1,..., KEn) are connected to a packet-oriented communications network (ATM-KN) via at least one transfer unit (ATM-HUB) and a switching system (PBX). To transmit data between the switching system (PBX) and the communication terminals (KE1,..., KEn) a time-slot-oriented data format (IOM-2) is provided for, which consists of a periodic sequence of channel-specific information segments (B1, B2, M, D). For the transmission of data via said communications network (ATM-KN) a user data area (N) of a data packet (ATMZ) used to transmit data via the communications network (ATM-KN) is divided into at least one first partial packet (TP1) and a second partial packet (TP2). In the first partial packets (TP1) the data of a channel-specific information segment (B1, B2, M, D) are transmitted. |
