About the Cisco NIM-1CE1T1-PRI Cisco network interface module
The Cisco NIM-1CE1T1-PRI network interface module delivers single-port WAN connectivity expansion for branch office and enterprise routing environments, enabling network engineers to add channelized E1/T1 ISDN PRI capacity to existing Cisco ISR 4000 Series platforms without requiring forklift upgrades.
This NIM card is engineered for organizations that require legacy telephony integration, carrier-grade voice services, or hybrid voice-data convergence on their branch routing infrastructure. The module supports both North American T1 (1.544 Mbps) and European E1 (2.048 Mbps) line rates with full ISDN PRI signaling via Q.931, delivering 23 bearer channels plus one delta channel on T1 circuits and 30 bearer channels plus one delta channel on E1 circuits. Built on Cisco IOS XE software, the NIM-1CE1T1-PRI integrates seamlessly into existing management and security frameworks. Network architects and IT procurement teams standardizing on Cisco routing platforms will benefit from flexible clocking options—internal, line-derived, or looped—and support for multiple T1 framing standards (ESF and SF) and E1 framing variants (CRC4 and non-CRC4), ensuring compatibility with diverse carrier and legacy network environments.
