SM-SRE-700-K9:先来介绍一下这个模块
Q:它是用来干嘛的?
A:思科服务就绪引擎模块是思科集成多业务路由器第2代(ISR G2)的高性能路由器刀片,可提供托管思科,第三方和自定义应用程序的功能。 这些模块拥有自己的处理器,存储,网络接口和内存,独立于主机路由器资源运行,有助于确保最大的并发路由和应用程序性能,同时减少物理空间占用空间,降低功耗并简化分支机构的IT管理。

VWIC2-2MFT-T1/E1:认识一下Voice/WAN interface cards
Q:它是用来干啥的?
multiflex VWIC结合了WAN接口卡(WIC)和语音接口卡(VIC)功能,在语音网关上,没它不行。它有第一、二、三代,这里VWIC2就表示第二代,VWIC3就是第三代。平时利星行遇到的最多应该就是:VWIC2-2MFT-T1/E1 .
Q:它长啥样?
它的要求:
①Cisco IOS Image -- To run these features on T1/E1 interfaces, you must install an IP Plus or IP Voice image (minimum) of Cisco IOS Release 12.3(14)T or a later release.
②VWIC Support -- The multiflex VWIC cards are supported on Cisco 2600XM series, Cisco 2691, Cisco 2800 series, Cisco 3700 series, and Cisco 3800 series routers when installed on the network modules listed in Components Used. The multiflex VWIC cards can also be installed in any VIC slot on the router.
③Independent Clocking Mode -- The independent clocking mode is supported only on these modules:
○ VWIC2-1MFT-G703
○ VWIC2-2MFT-G703
○ VWIC2-2MFT-T1/E1
○ VWIC2-1MFT-T1/E1

PVDM:high-density packet voice digital-signal-processor (DSP) modules 高密度分组语音数字信号处理模块
我想它的名字是不是Packets Voice DSP Modules这样的缩写哦。
PVDM也有PVDM2、PVDM3、PVDM4,更细的,PVDMx-y,例如PVDM3-128 (128-channel high-density voice DSP module )
PVDM3支持的是ISR2900、ISR3900系列
PVDM4应该在ISR4K上支持吧
同样的,看一下PVDM3和PVDM4的长相:
看一下PVDM3的型号:
