摘要：
The West German Post Office has implemented an ISDN pilot project in two cities in the German Federal Republic - Stuttgart and Mannheim. The Stuttgart part of the pilot project is based on a System 12 local exchange which has been enhanced by the inclusion of digital multiservice modules to provide ISDN features. The complete installation also covers network terminations, ISDN PABXs, basic access multiplexers, and terminal adapters, together with ISDN telephones and group 4 facsimile (64 kbit/s) on the subscriber side of the exchange. In a later phase, the ISDN user part of CCITT No 7 common channel signaling will be introduced on the trunk side.
