Cisco NM-1A-OC3MM-1V Network Module - 1-Port Multimode OC-3 ATM CES Module for Cisco 2600/3600/3700 Routers

Brand:
Cisco

Specifications

   Product Overview:
  • The Cisco NM-1A-OC3MM-1V is a high-speed 1-Port Multimode OC-3 ATM CES (Circuit Emulation Services) Network Module designed to provide reliable, fiber-based WAN connectivity for Cisco 2600, 3600, and 3700 series modular routers. This module delivers 155 Mbps ATM over multimode fiber, enabling efficient and scalable support for converged voice, video, and data applications.
  • It integrates circuit emulation services (CES) for transporting TDM traffic across ATM networks, making it ideal for service providers and enterprises requiring legacy TDM support over modern optical backbones. The NM-1A-OC3MM-1V supports ATM PVCs, OAM tools, ILMI, and robust Quality of Service (QoS) features, ensuring enterprise-grade performance.
  • This compact module enables organizations to transition legacy voice and data services to high-speed fiber-optic backbones without compromising reliability or control.
   Specifications:
  • Brand: Cisco 
  • Model: NM-1A-OC3MM-1V
  • Port Count: 1 x OC-3 (STM-1) Multimode Fiber
  • Interface Type: SC connector (multimode)
  • Maximum Bandwidth: 155 Mbps (OC-3 / STM-1)
  • Technology: ATM (Asynchronous Transfer Mode)
  • Circuit Emulation Services (CES): Supported (for T1/E1 transport)
  • Network Compatibility: SONET/SDH-compliant
  • ATM Features: PVCs, QoS, OAM (Operations, Administration, and Maintenance), ILMI
  • Form Factor: Network Module (NM slot)
  • Compatible Routers: Cisco 2600, 3600, 3700 Series
  • Cisco IOS Compatibility: Supported (verify specific IOS versions)
  • Power Source: Supplied via host router
   Features:
  • High-Speed OC-3 Throughput – Delivers 155 Mbps over multimode fiber
