Abstract
Telecommunication systems such as PABXs are known which comprise ISDN digital linecards with a number of ISDN basic access interfaces. A telecommunication device is proposed comprising configurable ISDN digital linecards. To this end the linecards are provided with configuration means for independently configuring each ISDN basic access interface with respect to the other ISDN basic access interfaces as to mode setting and phantom power feeding to the transmission line to be coupled to the interface. The modes to be set are ISDN-NT or ISDN-TE mode. It is achieved that the PABX can be set to customer specifications without customer specific linecards having to be manufactured. Accordingly, no high manufacturing change-over costs are involved and no expensive extra documentation sets have to be drawn up, as would have been the case when many customer specific linecards would have to be manufactured.
