本标准针对采用基于北美使用的7号信令系统（SS7）协议的公共信道信令（CCS）的网络连接所需的测试。网络连接5可以是北美国家内部或之间的连接。本标准提供了测试SS7协议0级信令连接控制部分（SCCP）互连网络之间兼容性的测试脚本列表。本标准参考了SS7协议标准中的材料。（见第2条）以前称为T1。235-2000（R2004）。

This standard addresses the testing required for internetwork connections employing Common Channeling Signalling (CCS) based on Signalling System No. 7 (SS7) protocol used in North America. The internetwork connection 5 be either within or between North American countries. This standard provides a list of test scripts for testing compatibility between the interconnecting networks of the Signalling Connection Control Part (SCCP) Class 0 of the SS7 protocol. This standard references material in SS7 protocol standards. (See clause 2.) Formerly known as T1.235-2000(R2004).
