Abstract

PURPOSE:To attain decentralized development of a large scale software by dividing an exchange processing of an ISDN exchange system, providing the standardized interface between same layers and adjacent layers, shielding or applying virtual processing layers from high-order to low-order layers or vice versa. CONSTITUTION:The titled system is divided into five layers; exchange processing hardware controls 11, 12, terminal state controls 21, 22, basic call controls 31, 32, additional service controls 41, 42, application softwares 51, 52. Then the same inter-layer standard interfaces 1-5 are provided between the same layers and adjacent inter-layer standard interface is provided between the adjacent layers. The hardware controls 11, 12 are processings to control the ISDN exchange system hardware O, the hardware is shielded by the processing and even when the physical hardware constitution is revised, the logical hardware constitution not giving effect onto the high-order layers is realized. Thus, the large scale software is developed decentralizingly.
