• Interface type: T1, E1, PRI (Primary Rate Interface)
• Module class: Cisco NM-series network module
• Compatibility: For use in supported Cisco routers with NM slots
• Data and voice support: Channelized operation for fractional T1/E1 and voice trunking
• Form factor: Standard network module for chassis integration
• MPN: NM-8CE1T1-PRI

Configuration & Options

• The module is ordered as a single unit with the MPN NM-8CE1T1-PRI.
• Supports individual port configuration for either T1 or E1 operation, depending on regional carrier requirements.
• PRI mode can be enabled per port for ISDN voice or data services.
• Cable and transceiver options are selected separately per port based on the deployed interface standard.
• No additional software license is indicated as required for basic operation.

Operating Conditions

This module is intended for installation inside Cisco routers in telecommunication rooms, data centers, or enterprise wiring closets where legacy T1/E1 circuits are present. It is suitable for environments transitioning from time-division multiplexing (TDM) to IP-based services, providing a stable interface for carrier connections. The module operates within standard router environmental specifications, requiring no external power supply.
