1.制作一份ETS，该ETS必须涵盖以下项目:；1.1选择下层协议参数1.2选择下层协议携带的参数（例如HLC，LLC的代码点）与SPS5联系。//1.3选择ETS 300 075和EN 41216（ISP 10607）简单FTAM中文件传输协议describ提供的设施。选择适当的参数值，以实现无选项内核协议。//2.为其他相关团队提供进一步的要求和协调（ISDN文件传输API和ISDN文件传输一致性测试）。

1. Produce an ETS which has to cover the following items; 1.1 Selection of lower layer protocols parameters 1.2 Selection of parameters carried by lower layer protocols (eg code points for HLC, LLC,.) in liaison with SPS5. // 1.3 Selection of facilities offered by the file transfer protocol describ in ETS 300 075 and EN 41216 (ISP 10607) Simple FTAM. Selection of the appropriate parameter values with the aim to have an option free kernel protocol. // 2. Provide further requirements and coordination for other related Teams ( API for File Transfer over ISDN and Conformance test for File Transfer over ISDN ).
