nim-4mft-t1/e1 overview
nim-4mft-t1/e1 is a cisco voice/wan module (4-port t1/e1) for isr 4000 series. Cisco® fourth-generation 1-, 2-, 4-, and 8-port t1/e1 multiflex trunk voice and wan network interface modules (nims) support data and voice applications on the cisco 4000 integrated services routers (figure 1). These cards combine wan-interface-card (wic), voice-interface-card (vic), isdn primary rate interface (pri), dial-access integration, and channelized-data (ce1t1) functions to provide superior flexibility, versatility, and investment protection through their many uses. Customers who choose to integrate data and voice in multiple steps preserve their investment in a t1/e1 wan interface. These nims are not supported with cisco 2900 and 3900 integrated services routers
