NIM-8MFT-T1/E1

The Cisco Fourth-Generation Multiflex Trunk Voice and WAN network interface module NIM-8MFT-T1/E1 provides 8 T1/E1 ports to support both data and voice applications on the Cisco 4000 series router. The cards combines WAN, Voice, ISDN Primary rate interface, ANI and channelized-data functions together to deliver superior flexibility, versatility and investment protection. The fourth-generation Cisco T1/E1 NIMs add improvements over the Cisco Second- and Third-Generation T1/E1 Multiflex Trunk Voice and WAN Interface Cards (MFT VWIC2s and VWIC3s, respectively). The fourth-generation T1/E1 modules enable each port to be clocked from an independent clock source for data applications. Voice applications can now be clocked independently from data applications, with all ports for voice applications clocked from a single source. The NIM-8MFT-T1/E1 module has its own PVDM4, so each module can be connected to a different service provider with no single clock domain restriction.
