摘要： An Asynchronous Transfer Mode (ATM)-based distributed network switching system includes an ATM switching network (26) that dynamically sets up individual switched virtual connections. The system also includes multiple access interworking function (A-IWF) devices each operating as a gateway that enables customer premises devices to directly interface into the distributed ATM switching fabric. The system further includes a centralized control and signaling interworking function (CS-IWF) device that performs call control functions and adminstrative functions and is adapted to interface narrowband and broadband signaling for call processing and control within the ATM switching network (26). The CS-IWF device (30) may be a server farm.

摘要翻译： 基于异步传输模式（ATM）的分布式网络交换系统包括动态建立单个交换虚拟连接的ATM交换网络（26）。 该系统还包括多个接入互通功能（A-IWF）设备，每个设备作为网关操作，使客户驻地设备能够直接接入分布式ATM交换结构。 该系统还包括执行呼叫控制功能和管理功能的集中式控制和信令互通功能（CS-IWF）设备，并适用于在ATM交换网络（26）内为窄带和宽带信令接口进行呼叫处理和控制。 CS-IWF设备（30）可以是服务器群。
