    • To perform call control signaling between a user and a telecommunications switching network (and end-to-end between users), a portion of the multiplex overhead of a multiplexed data stream is formatted so that it includes the call control signaling. This in-band signaling is actually in the multiplex overhead and not in the user data as in standard multiplex formats. At nodes of the network and at user devices connected to the network, the call control signaling is extracted from the overall data stream and is processed to selectively generate new and responsive call control signaling for completing the signaling operations. The invention is useful over the entire multiplex hierarchy.
    • 为了在用户和电信交换网络之间(和用户之间的端到端)执行呼叫控制信令,多路复用数据流的多路开销的一部分被格式化,使得它包括呼叫控制信令。 该带内信令实际上是在多路复用开销中,而不是像标准多路复用格式那样在用户数据中。 在网络的节点和连接到网络的用户设备处,从总体数据流中提取呼叫控制信令,并且被处理以选择性地生成新的和响应的呼叫控制信令以完成信令操作。 本发明在整个多重层次结构中是有用的。
