您要查找的是不是：
- A packet used by a data terminal equipment ( DTE ) or by a data circuit terminating equipment ( DCE ) to indicate a temporary inability to accept additional packets for a virtual call or permanent virtual circuit. 数据终端设备(DTE)或数据电路端接设备(DCE)使用的信息包，用来表示暂时无法接收虚拟呼叫或永久虚拟电路的附加信息包。
- virtual call and permanent virtual call 虚呼叫和永久呼叫电路承载业务类别
- permanent virtual calling 久永的虚呼叫
- permanent virtual call 永久虚拟呼叫
- A permanent virtual circuit is a path that stays open even when no traffic is using it. 永久性虚拟电路是即便没有信息流通过时仍保持开放的通道。
- Typically, permanent virtual circuits are set up between multiple backbone switches and between switches and devices with heavy network traffic. 一般而言，永久性虚拟电路建在多个主干网交换机之间和交换机与网络信息流量大的设备之间。

- DLCI Data Link Connection Identifier ( DLCI) is a unique number assigned to a Permanent Virtual Circuit (PVC) end point in a frame relay network. 本策略的目的使为了定义任何外部主机连接到企业网络的标准。这些标准是为了使非授权使用企业资源造成的损害及相应的企业信息暴露最小化。
- At JIT compilation time, the common language runtime does not usually have enough information about the target of a virtual call. 在JIT编译时,公共语言运行库通常没有关于虚调用的目标的足够信息。
- These channels are not dedicated physical connections,but are permanent virtual connections or switched virtual connections that are deconstructed when no longer needed. 这些信道不是专用的物理连接，而是永久虚拟连结或交换的虚拟连结，当再不需要时，这些连结可以拆掉。
- For each event dispatch, one virtual call is followed by a linear search for the appropriate reaction, using one RTTI comparison per reaction. 对于每一个事件分派，将有一次虚拟函数调用加一个对合适反应的线性查找，每个反应使用一个RTTI比较。

- However,the concern is that voice traffic in frame environments built with permanent virtual circuits (PVC) will not be as cost-effective as frame nets built with switched virtual circuits (SVC). 但问题是，用永久虚拟电路（PVC）建立起来的帧环境中的话音通信的性能价格比不如用交换虚拟电路（SVC）建立起来的帧网络。
