This paper discusses the potential benefits of H0-based ISDN. By providing widespread H0 (384 kb/s) call services, much like today's telephone systems, it should be possible to bring multimedia public communication services to the general public. Small distributed switching systems and reuse of existing metallic loops will contribute to its economical construction and rapid expansion into general use. System-on-a-chip technology, expected to appear soon, will make the necessary small switching systems cost-effective. The short loops resulting from the distribution will allow H1-band (1.5/2.0 Mb/s) metallic loops to be used. In terms of function, the distributed switching nodes will permit node-by-node customization, which will make switching systems simple and flexible. The proposed node-by-node customization will allow subscribers in each different node to choose they prefer. H0-based ISDN will provide various type of nodes, supporting various types of subscriber loops, whereas present public networks enforce standardized subscriber loops. Furthermore, when customized subscriber switching systems accommodate star-LAN interfaces as subscriber loops, the public network will be able to provide LAN services in a closed area as part of the public network services. The LAN users will be able to converse with ordinary residential subscribers through H0-calls. This will lead to the integration of LANs and public networks.
