Fourth-Generation Multi-flex Trunk Voice/Channelized Data T1/E1 Module - expansion module - T1/E1 x 1 - NIM-1CE1T1-PRI

NIM-1CE1T1-PRI is a Multiflex Trunk Voice and WAN network interface module for ISR 4000 series. 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 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 2900 and 3900 Integrated Services Routers.
