软交换是网络演进以及下一代分组网络的核心设备之一，它独立于传送网络，主要完成呼叫控制、资源分配、协议处理、路由、认证、计费等主要功能，同时可以向用户提供现有电路交换机所能提供的所有业务，并向第三方提供可编程能力。-Softswitch is the network evolution and next-generation packet networks, one of the core equipment, it independent of the transmission network, mainly to complete call control, resource allocation, protocol processing, routing, authentication, billing and other major features, as well as to provide users with existing circuit switches can be provided for all operations to a third party to provide programmability.

在多数情况下,集成电路芯片的管脚不会全部被使用。例如74ABT16244系列器件最多可以使用16路I/O管脚,但实际上通常不会全部使用,这样就会存在悬空端子。所有数字逻辑器件的无用端子必须连接到一个高电平或低电平,以防止电流漂移（具有总线保持功能的器件无需处理不用输入管脚）。究竟上拉还是下拉由实际器件在何种方式下功耗最低确定。-in most cases, the IC chips will not pin all been used. For example, 74 ABT16244 series device can use up to 16 Road I/O pins. but usually not all use, so there will always be vacant terminal. All digital logic device useless terminals to be connected to a serial or low-level. to prevent the current drift (with the bus maintain functional devices need not deal with the importation of pins). What to draw from the drop-down or what the actual device under way to determine the minimum power consumption.
