Description
The Cisco NIM-4MFT-T1/E1++ is a four-port Multiflex Trunk Voice and Clear-Channel Data T1/E1 network interface module designed for Cisco 4000 Series Integrated Services Routers. It enables simultaneous support for voice and WAN data applications, allowing organizations to consolidate infrastructure while maintaining flexibility and performance.
This module supports T1, fractional T1, E1, and fractional E1 connections with integrated DSU/CSU functionality, eliminating the need for external devices. Each port can operate independently, making it ideal for branch offices, service provider connectivity, and hybrid voice-data environments. When paired with an optional PVDM module, the NIM-4MFT-T1/E1++ enables packet voice services such as VoIP, while still supporting clear-channel data transport.
Engineered for scalable deployments, the NIM-4MFT-T1/E1++ delivers reliable connectivity, efficient trunk utilization, and investment protection for evolving enterprise networks.
