本T1技术报告介绍了通过宽带传输技术支持窄带服务所需的程序、信息流和信息元素。该报告提供了通过宽带传输技术支持窄带服务的要求。其范围仅限于服务节点（SN）和相关协议在呼叫控制和承载控制级别上的功能，以在ATM骨干网络上为能力集1（CS 1）提供该能力。

This T1 technical report presents the procedures, information flows and information elements needed for supporting narrowband services via broadband transport technologies. The report provides requirements for the support of narrowband services via broadband transport technologies. Its scope is limited to functionality of the Serving Node (SN) and associated protocols at the call control and bearer control levels needed to provide this capability across an ATM backbone network for Capability Set 1 (CS 1).
