IDSL(ISDN DSL)的首要市场功效即:它既是对当前网络策略和供应的补充,也是对用户在设备和软件上投资的补充。因此,它有望更快地获得推广。IDSL也与使用远程交换用户的期望相符,在一份1996年调研报告中,ICMI公司注意到:有十分之九的远程交换网络用户均认为,分支机构适于远程交换。 IDSL的最终问题也与连接速度有关。DSL技术中的IDSL的128Kbps最高速度在当前PC机串行端口上的权能范围之内,所以带有一个串行接口的简单IDSL终端适配器足够连接用户。如果该适配器
The primary market effect of IDSL (ISDN DSL) is that it complements current network policies and offerings as well as complements the user’s investment in equipment and software. Therefore, it is expected to get promotion sooner. IDSL is also in line with the expectation of using remote exchange users, and in a 1996 research note, ICMI noticed that nine out of ten of the users of remote exchange networks considered the branch office suitable for remote exchange. The final issue with IDSL is also about connection speed. The highest 128Kbps speed of IDSL in DSL technology is within the capabilities of the current PC serial port, so a simple IDSL terminal adapter with a serial interface is sufficient for connecting users. If the adapter
