NIM-2FXSP
NIM-2FXSP 2-Port Network Interface Module - FXS, FXS-E and DID
Cisco®4000系列集成服务路由器(ISR)承载了Cisco网络接口模块(NIM),这些模块是从增强型高速WAN接口卡(EHWIC)发展而来的,提高了端口密度和模块能力。4000系列上最多有三个集成NIM插槽,可实现灵活的配置。NIM支持在线插入和移除(OIR),减少了新模块或替换模块所需的停机时间。
可用模块包括2端口和4端口外汇站(FXS)、直接向内拨号(DID)、外汇局(FXO)、2端口FXS和4端口FXO的组合、4端口耳口(E/M)以及2端口和四端口基本速率接口(BRI)(图1)。BRI卡仅支持语音功能。NIM有一个专用的数字信号处理器(DSP),将用于时分复用(TDM)模拟语音服务。表1列出了可用的模块。
