Cisco NIM-4MFT-T1／E1=

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.
