摘　　要：一体网络含有两层意思：１）多个专用网络变为单一网络；２）单一网络中每种业务都与原来的专用网络中的使用完全一样，且可以和专用网的业务无隙互通。ＩＳＬＮ是ＬＡＮ中增加电话功能而实现的，它是单位内部的一体化网络。ＰＲＥ－ＩＳＤＮ是在现有程控数字电话交换网上实现的直接用户数字连接。以ＰＲＥ－ＩＳＤＮ为远程骨干把ＬＡＮ、ＩＳＬＮ、电话网互连成一体网络，可以实现ＬＮＮ、电话两种业务在公用网和局域网之间的全面互通，具有广阔的应用前景，而成本却十分低廉。By 'Organic Network' we have two meanings:1)A single network is integrated from many specific networks.2)Every service in the single network is just the same as which in the original network when used,and can interwork with the original network without gap.ISLN is developed out by attaching telephony functions to LANs,and is the organic network for the enterprise.PRE-ISDN is a direct digital links network implemented at the digital program-controlled switches.To connect LANs,ISLNs and telephony networks into an organic network by using PRE-ISDN as a backbone,the overall interworking for LAN,telephone two services between LAN, public two type networks can be achieved with wide useful future while keeping cost low.
