NIM-1T-RF

1-Port Serial WAN Interface card REMANUFACTURED

NIM-1T-RF is a professionally remanufactured Cisco Network Interface Module (NIM) with a single T1/E1 WAN port, designed to provide serial WAN connectivity for Cisco ISR 4000 Series routers deployed in enterprise branch offices and service provider edge environments. This module slots into a NIM bay on supported ISR 4000 platforms, enabling cost-effective T1 or E1 leased-line connectivity without requiring an external CSU/DSU in many configurations.

This remanufactured NIM has been restored to meet Cisco original equipment specifications and undergone full inspection and functional testing prior to shipment. Validation includes verification of T1/E1 line signaling and framing protocols, NIM bay interface compatibility with ISR 4000 host chassis, and confirmation of proper clock source and timing synchronization capabilities.

Key Features:
• Single T1 (1.544 Mbps) or E1 (2.048 Mbps) WAN port for flexible North American and international deployments
• Compatible with Cisco ISR 4321, 4331, 4351, 4431, and 4451 router platforms via NIM bay interface
• Supports framing formats including SF, ESF (T1) and CRC4, no-CRC4 (E1) for carrier network interoperability
• Integrated CSU/DSU functionality eliminates the need for external data service units on T1 circuits
• Supports line coding options including AMI and B8ZS (T1) and AMI and HDB3 (E1)
• "RF" Cisco Certified Remanufactured designation ensures the unit meets original Cisco quality and performance standards
