Reliable OC12 connectivity. We've seen zero packet loss since installing this module in our production environment. The Eng 3 architecture is noticeably more efficient.
Excellent port density and the 512MB memory handles our ATM traffic perfectly. A robust solution for metropolitan aggregation sites.
Professional grade ATM module. It integrated perfectly with our existing 12000 chassis and has provided steady performance under heavy load.
Top-tier reliability for our IR spans. This card is a workhorse for legacy ATM transport, delivering consistent throughput without any errors.
Solid build quality and easy configuration. It's been a dependable part of our network fleet for months. Great ROI for B2B infrastructure.
The module is a 4-port OC-12/STM-4 ATM interface card with Eng 3 processing and a 1×512 MB default memory, designed for high-speed cell relay in enterprise routers.
Each port supports OC-12/STM-4 at 622 Mbps, for an aggregate forwarding capacity of up to 2.5 Gbps across four ports.
Each port uses an SC single-mode fiber connector with IR-SC optical interface for reliable, low-loss transmission.
The 512 MB default RAM supports ATM cell buffering, queuing and OAM functions to maintain throughput and low latency.
Yes, the 4OC12X/ATM-IR-SC is fully compatible with Cisco 7600, 6500 and select aggregation series platforms that support WAN interface cards.
Power down the router, slide the module into an available WIC/Multiservice slot until it clicks, then power up and verify the interface status.
Yes, it provides full ATM Adaptation Layer 5 (AAL5) support for IP over ATM and frame relay emulation applications.
Memory is fixed at 512 MB and cannot be upgraded; it is factory-loaded to ensure optimal ATM performance.
Eng 3 is the third-generation ATM engine offering enhanced cell processing, lower latency and advanced QoS capabilities.
It supports up to 4,096 virtual circuits (PVCs/SVCs), enabling large-scale ATM deployments and multi-tenant segmentation.
The module supports cell-level policing, shaping, priority queuing and congestion avoidance to meet stringent SLAs.
Operational temperature is 0 °C to 40 °C, relative humidity 10%–90% non-condensing, with compliance to industry safety standards.
Enter global config, define the atm interface, assign PVC parameters (VPI/VCI), and apply encapsulation AAL5 aal5mux or aal5snap.
The IR-SC transceiver supports up to 10 km single-mode links at a wavelength of 1310 nm for long-haul connectivity.
Yes, it supports voice trunking over AAL2 and AAL5 for cost-effective, low-latency voice transport.
The module carries a limited lifetime warranty with next-business-day replacement and optional Cisco SMARTnet service for advanced support.
