The 4OC3X/ATM-IR-SC is a high-performance network interface card featuring four OC3/STM1 ports, an ATM Engine Level 3, and 512 MB of onboard memory for scalable bandwidth and low-latency cell processing.
Key features include quad OC3/STM1 fiber ports, ATM Engine 3 for hardware-accelerated cell switching, 512 MB default buffer memory, SC connectors, up to 155 Mbps per port, QoS and traffic-shaping support.
Power down the chassis, insert the 4OC3X/ATM-IR-SC into a compatible PCI slot, secure the bracket, connect SC‐terminated fiber cables, then power up and verify detection in the network OS.
Each OC3/STM1 interface delivers up to 155.52 Mbps of full-duplex throughput, providing an aggregate bandwidth of 622.08 Mbps across all four ports.
ATM Engine 3 provides advanced cell header processing, hardware-based classification, and jitter reduction, offloading central CPU resources for improved overall system performance.
The 512 MB onboard buffer optimizes burst handling, supports large routing tables, enhances Quality of Service by smoothing traffic, and improves overall cell‐switching efficiency.
It supports ATM UNI 3.1/4.0, IMA, PPP over ATM, Frame Relay over ATM, GFP, and standard OAM functions for comprehensive ATM network integration.
Yes, it interoperates with any OC3/STM1-compliant router, switch, optical transport platform, or ATM network element from leading vendors.
Use your network OS CLI or GUI to assign port identifiers, set VPI/VCI values, define ATM PVCs or SVCs, and enable SC interface settings according to vendor guidelines.
The 4OC3X/ATM-IR-SC draws 12 W at 3.3 V DC and requires a host chassis that provides compliant PCI power rails.
Maintain ambient temperatures between 0 °C and 50 °C, relative humidity 5%–85% non-condensing, and vibration within standard telecom rack tolerances.
Yes, it supports hot-standby failover using standard ATM redundancy protocols and can be configured for link aggregation across multiple OC3/STM1 ports.
Monitor traffic using SNMP MIB‐II counters, ATM MIBs, or your network OS’s CLI/GUI tools to view per-port and per-VCI cell statistics in real time.
The card includes a one-year limited hardware warranty, with optional extended support plans offering advanced hardware replacement, firmware updates, and 24/7 technical assistance.
Perform firmware upgrades via the host’s loader utility over the serial console or network management interface, following the vendor’s published upgrade procedure.
It is ideal for carrier backhaul, enterprise WAN aggregation, VoATM, video distribution, Metro-Ethernet uplinks, DSLAM backhaul, and legacy ATM network integration.
