In a multinational retail chain, IT teams deploy the NM-1A-OC3-POM-ATM module with a single POM (SFP) slot in Cisco 2900 Series routers to aggregate point-of-sale transactions at OC-3 (155 Mbps) speeds. Leveraging ATM virtual circuits ensures low-latency, lossless transfer for real-time credit card processing and inventory synchronization. Outcome: PCI-DSS compliance, 99.99% transaction uptime, and a 30% reduction in WAN costs through optimized bandwidth utilization.
A Tier-1 telecom operator integrates the NM-1A-OC3-POM-ATM module into Cisco Aggregation Services Routers to backhaul multiple 3G/4G cell sites over ATM on OC-3. The single POM (SFP) slot provides future-proof interface flexibility, while carrier-grade QoS on ATM PVCs guarantees SLA performance. Benefit: scalable backhaul capacity, 40% faster service provisioning, and simplified fiber management for upcoming LTE expansions.
A global financial services firm links two data centers 50 miles apart using the NM-1A-OC3-POM-ATM module deployed in Cisco 4000 Series routers. ATM over OC-3 delivers deterministic latency and microsecond-level jitter control essential for high-frequency trading applications. Result: sub-3 ms round-trip times, strict SLA adherence, AES-256 encrypted replication, and a 25% boost in trade-execution reliability.

Reliable module for ATM networks.
Met technical expectations fully.
Solid Cisco ATM solution.
The Cisco NM-1A-OC3-POM is an ATM OC3 network module with a single POM (SFP) slot, delivering up to 155.52 Mbps OC3 connectivity in compatible Cisco routers.
The NM-1A-OC3-POM is supported on Cisco 2800, 3500, 3600, 3700, 3800, and 7200 Series routers with an available network module slot.
This module supports OC3 data rates of up to 155.52 Mbps for ATM transport.
It uses a single POM (pluggable optics module) slot compatible with Cisco SFP transceivers for flexible optical connectivity.
Compatible SFPs include Cisco-approved OC3-rated transceivers in both single-mode and multimode options per the Cisco Transceiver Compatibility Matrix.
Yes, both the NM-1A-OC3-POM module and its SFP transceiver are hot-swappable to ensure minimal service disruption.
Power down the router, insert the NM-1A-OC3-POM into an open network module slot, secure it, install a compatible SFP, then power up the router.
Use the Cisco IOS CLI: enter interface ATM0/0/0, apply 'encapsulation aal5snap', configure 'pvc <vpi> <vci> bandwidth 15552', and set any required ATM parameters.
Run 'show interface atm' to check status, 'show hw-module subslot 0 transceiver' to verify optics, confirm VPI/VCI settings, and consult 'show logging' for errors.
It operates from 0 °C to 45 °C (32 °F to 113 °F), stores from –40 °C to 70 °C (–40 °F to 158 °F), and complies with Cisco EMC and safety standards.
The module is covered by Cisco’s limited lifetime warranty with next-business-day replacement and is eligible for SMARTnet support services.
No, the NM-1A-OC3-POM is designed exclusively for ATM OC3 transport and does not provide SONET/SDH framing.
Typical use cases include high-speed enterprise WAN links, interoffice ATM connections, and temporary or backup optical backhaul services.
Use 'show hw-module subslot 0 status', 'show interface atm0/0/0', and 'show controllers atm' to confirm module health and operational parameters.
The NM-1A-OC3-POM is available through authorized Cisco resellers, channel partners, and Cisco’s online store with global shipping options.
