摘　　要：现有ＬＡＮ的传输能力在很大程度上可满足传输综合业务的要求。现有ＬＡＮ适配于ＩＳＤＮ的直接方法是在ＬＡＮ上实现ＩＳＤＮ功能，从而达到ＬＡＮ工作站与ＩＳＤＮ间业务的完全互通。在ＬＡＮ上实现ＩＳＤＮ功能的方案是：（１）在ＬＡＮ上增加综合业务传输接口，该接口不同于ＬＡＮ软件提供的接口，具有实时性，而且该接口的设计应使ＬＡＮ应用与综合业务应用间互相独立；（２）开发在工作站上与ＬＡＮ应用软件并发运行的综合业务应用软件，这些软件应按ＩＳＤＮ的业务控制方式实现，以便能与ＩＳＤＮ直接互通。ＬＡＮ与ＩＳＤＮ互通，不但可使ＬＡＮ工作站作为ＩＳＤＮ的用户终端，还可在ＩＳＤＮ承载业务支持下扩大ＬＡＮ应用的通达范围。初步试验表明，这种方案是可行的。The transmission ability of existing LANs can meets the requirement to some extent to transmit the information of integrated services. The author thinks that the direct way to match a LAN with ISDN is to realize in LAN all services of ISDN. The design of this strategy includes: 1) adding a real-time transmission interface into LAN protocol layers, which is independent of LAN applications and integrated services applications in the progress of execution and development; 2) adding a concurrent integrated services software on LAN station, which is an implementation of ISDN manner and is interoperable with ISDN services. The paper discusses issues in designing and implementing in detail. An preliminary trial shows the feasiblity of the strategy.
