NM-1A-T3/E3 Use Case
High-Performance WAN Backbone for Financial Trading Systems
In a securities trading firm requiring ultra-low latency and deterministic throughput, integrating the NM-1A-T3/E3-1-Port T3/E3 ATM network module into Cisco 3600/3700 series routers delivers a dedicated 45 Mbps (T3) or 34 Mbps (E3) ATM link between data centers. Outcome: Sub-millisecond transaction times, guaranteed bandwidth for market data feeds, and built-in failover maintain regulatory compliance and protect against costly downtime.
Converged Voice/Data Services for Telecommunications Carriers
A regional telco leverages the NM-1A-T3/E3-1-Port T3/E3 ATM module on Cisco 2600/3600 routers to carry legacy TDM voice trunks alongside IP-based data traffic over a single ATM PVC. Outcome: Simplified network architecture, unified service provisioning, and 30% reduction in capex by consolidating multiple physical circuits while ensuring QoS-prioritized voice channels.
Secure Backup and Load-Balanced Connectivity for Government Networks
A government agency implements the NM-1A-T3/E3-1-Port T3/E3 ATM module on Cisco ISR platforms to establish redundant ATM paths between central and field offices. Outcome: Automated link failover, dynamic load balancing, and traffic shaping enforce strict SLA parameters—ensuring uninterrupted access to critical applications and adherence to federal security mandates.

Questions & Answers
What is the Cisco NM-1A-T3/E3 1-Port T3/E3 ATM Network Module?
The Cisco NM-1A-T3/E3 is a modular interface card that provides one T3 or E3 ATM port for high-speed WAN connectivity on compatible Cisco routers.
Which Cisco routers are compatible with the NM-1A-T3/E3 module?
The NM-1A-T3/E3 is supported on Cisco 2800, 2900, 3700, 3800 and 3900 Series Integrated Services Routers with one available network module slot.
What data rates does the NM-1A-T3/E3 module support?
The NM-1A-T3/E3 supports full-duplex rates of up to 45 Mbps for T3 and up to 34 Mbps for E3, enabling high-bandwidth ATM services.
How do I install the NM-1A-T3/E3 network module?
Power down the router, insert the NM-1A-T3/E3 into an available module slot, secure it with screws, reconnect power, and verify with the show module command.
Which cable type is required for the NM-1A-T3/E3 port?
Use a male DB-15 to female RJ48 cable to connect the NM-1A-T3/E3 ATM port to your T3/E3 service provider demarcation.
Can I configure both T3 and E3 services on the NM-1A-T3/E3?
Yes. The module auto-detects and configures for either T3 (DS3) or E3 signaling via CLI commands such as ‘t3clock internal’ or ‘e3clock internal’.
Does the NM-1A-T3/E3 support ATM Quality of Service (QoS)?
