Cisco NIM-4MFT-T1/E1

The Cisco NIM-4MFT-T1/E1 is a network interface module (NIM) designed for use with Cisco Integrated Services Routers (ISRs). It provides four T1 or E1 ports for connecting to traditional TDM (Time-Division Multiplexing) networks. This module allows for the integration of T1 or E1 circuits into an IP-based network, enabling voice and data services over the same network infrastructure. It supports both voice and data applications, making it suitable for organizations that require connectivity to legacy TDM networks.
