Brand: Cisco · SKU: NIM-4E/M · MPN: NIM-4E/M · Category: Components
The Cisco NIM-4E/M is a 4-Port E/M Network Interface Module designed to expand the capabilities of Cisco 4000 Series Integrated Services Routers (ISRs). It provides four E&M analog voice interfaces for legacy PBX interconnects. This module supports online insertion and removal (OIR) and is compatible with Cisco IOS Releases XE3.14.3, XE3.15.1, XE3.16 and above. It allows for seamless integration of existing analog voice infrastructure with IP telephony by converting mouth-and-ear circuits to SIP, suitable for SMB legacy PBX integration and resilient voice services in WAN failover scenarios. Some vendor information suggests features like auto-negotiation, Wake-on-LAN, Jumbo Frames, and QoS support for Ethernet applications, but the primary function of NIM-4E/M is analog voice/E&M connectivity.
