    • A communication switching system has a plurality of switch nodes each of which is responsive to a failure of the primary signaling channel (421) providing the common signaling channel in a facility access service (FAS) group to immediately switch to the secondary signaling channel (420) of the FAS group. This switching occurs quickly so that no calls are dropped within the FAS group. Any logical links being communicated on the primary signling channel are transferred to the secondary signaling channel with no data packets being irreplaceably lost. A first physical object (412) is established to control a physical protocol on the primary signaling channel, and a second physical object (417) is established to control the physical protocol on the secondary signaling channel. A single software object (400) is established to always control the first layer of software protocol on the common signaling channel whether that is the primary or secondary signaling channel. When failure of the primary signaling channel is detected, information for the common signaling channel is routed from the second physical object to the software object, thereby preserving the common signaling channel.
    • 通信交换系统具有多个交换节点,每个交换节点响应于在设备接入服务(FAS)组中提供公共信令信道的主信令信道(421)的故障,以立即切换到辅助信令信道(420 )的FAS组。 此切换发生得很快,因此FAS组内不会丢弃任何呼叫。 在主要信号通道上传送的任何逻辑链路被传送到辅助信令信道,没有数据分组被不可替代地丢失。 建立第一物理对象(412)以控制主信令信道上的物理协议,并且建立第二物理对象(417)以控制辅信令信道上的物理协议。 建立单个软件对象(400)以始终控制公共信令信道上的第一层软件协议,无论是主信令信道还是辅助信令信道。 当检测到主信令信道的故障时,用于公共信令信道的信息从第二物理对象路由到软件对象,由此保留公共信令信道。

    • A computer connected to an ISDN central office switch via an ISDN digital subscriber line, provides management information regarding activities of a plurality of telephone agents. The computer has shared call appearances with a number of telephone agent stations and receives shared call appearance associated messages from the switch reflecting call handling messages exchanged between the ISDN switch and each of the agent stations. The messages are interpreted by the computer, which generates station status information and management information such as the number of calls handled, average holding time per call, etc. The computer may be connected simultaneously to several central offices via ISDN subscriber lines and generate management information for a group of geographically separated agents, such as home telemarketing agents operating out of their individual homes and connected to different central offices. Based on the generated status and management information, the computer performs an incoming call management function by selecting agents connected to different switches for handling incoming calls and transmitting to the ISDN switch appropriate messages for causing the switch to transfer incoming calls to the selected agents. Additionally, the computer performs an outgoing call management function by initiating outgoing calls and causing the switch to connect an answering party to an agent, selected by the computer on any of the switches.
    • 通过ISDN数字用户线连接到ISDN中心局交换机的计算机提供关于多个电话代理的活动的管理信息。 计算机具有与多个电话代理站的共享呼叫出现,并从该交换机接收反映在ISDN交换机和每个代理站之间交换的呼叫处理消息的共享呼叫状态相关消息。 消息由计算机解释,其产生站状态信息和管理信息,例如处理的呼叫数,每呼叫的平均保持时间等。计算机可以经由ISDN用户线同时连接到多个中心局,并产生管理信息 对于一组地理上分离的代理商,例如在其个人住宅中运行并连接到不同中心局的家庭电话销售代理。 基于生成的状态和管理信息,计算机通过选择连接到不同交换机的代理来处理来话呼叫并向ISDN交换机发送适当的消息以使交换机将来话呼叫转移到所选择的代理,来执行呼入管理功能。 此外,计算机通过发起呼出呼叫来执行呼出呼叫管理功能,并且使得交换机将应答方连接到由计算机在任何交换机上选择的代理。
