Cisco NIM-1CE1T1-PRI

The Cisco NIM-1CE1T1-PRI is a network interface module (NIM) designed for use with Cisco Integrated Services Routers (ISRs). It provides a single port for connecting a T1 or E1 circuit to the router. The "PRI" in the model name stands for Primary Rate Interface, which refers to the type of digital telephony service that the module supports. This module allows the router to connect to a digital telephony network, such as a PRI ISDN or a T1/E1 trunk line, enabling voice and data communication over the network.
