    • A method of and apparatus for transmitting SS7 signals between a single node (such as, for example, Service Control Points (SCPs), Service Switching Points (SSPs) and Signalling Transfer Points (STPs)) and a plurality of other nodes is disclosed. The method involves connecting a node to an Asynchronous Transfer Mode (ATM) network through a High Speed Link (HSL). A virtual channel for each of the other nodes connected to the ATM network is provisioned on the HSL. Each channel is identified by a Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI) pair. SS7 signalling data from the single node will be encapsulated with the VCI+VPI pair in an ATM cell and transmitted on the HSL to the ATM network where the ATM cell is transmitted to another node over a Permanent Virtual Circuit (PVC) or Switch Virtual Channel (SVC). The other node may also be connected to the ATM network through a similar HSL with multiple virtual
    • 公开了在单个节点(例如,服务控制点(SCP),业务交换点(SSP)和信令传输点(STP))以及多个其他节点之间传输SS7信号的方法和装置。 该方法包括通过高速链路(HSL)将节点连接到异步传输模式(ATM)网络。 在HSL上提供连接到ATM网络的每个其他节点的虚拟信道。 每个通道由虚拟路径标识符(VPI)和虚拟信道标识符(VCI)对来标识。 来自单个节点的SS7信令数据将被封装在ATM信元中的VCI + VPI对中,并在HSL上传输到ATM网络,其中ATM信元通过永久虚拟电路(PVC)或交换机虚拟信道 (SVC)。 另一个节点还可以通过具有多个虚拟的类似HSL连接到ATM网络
