简介

在此配置中,两不同的X.25资源(我们使用dspu-host模拟在此设置的终端设备)。关于下行流物理单元(DSPU)的更多信息,参考这些文档:

这两个终端设备连通用不同的适配器在X.25的大型机站点。远程X.25资源为不同的目的地址配置(用不同的长度和不同的地址)。X.121目的地址匹配路由器的“qllc dlsw subaddress”的所有呼入呼叫被调度对加强版数据链路交换(DLSW+) (与ID.STN IND)。当DLSw+接收“时能到达”关于一个虚拟MAC地址的查询在池,映射对指定的虚拟MAC地址的限定式逻辑链路控制(QLLC)代码尝试设置虚拟电路到X.121地址。如果呼入呼叫接收, QLLC发送与一个虚拟MAC地址的一ID.STN.IND从池到DLSw+。
