Questions & Answers
What is the Cisco NM-CEM-4SER Network Module?
The Cisco NM-CEM-4SER is a 4-port serial circuit emulation over IP network module that enables T1/E1 service extension over packet networks with carrier-grade reliability.
What are the key features of the NM-CEM-4SER?
Key features include four T1/E1 serial ports, low‐latency circuit emulation, QoS support, in-band management, and seamless integration with Cisco IOS routers.
Which Cisco routers are compatible with NM-CEM-4SER?
The NM-CEM-4SER is compatible with Cisco 2600XM, 3600, 3700, 3800 and 7200 series routers running Cisco IOS Software with supported feature sets.
How many serial ports does the NM-CEM-4SER provide?
It provides four independent T1/E1 serial ports for simultaneous circuit emulation services.
Which circuit types can the NM-CEM-4SER emulate?
It emulates both T1 (1.544 Mbps) and E1 (2.048 Mbps) circuits with transparent payload transport.
What protocols does the NM-CEM-4SER support?
It supports SAToP, CESoPSN, RTP, H.223, FRF.11 (ATM), and other industry-standard circuit emulation protocols.
How do I install the NM-CEM-4SER in my router?
Power down your Cisco router, insert the module into an available network module slot, secure the module, and power the router back on. The module is hot-swappable in supported platforms.
How do I configure circuit emulation on NM-CEM-4SER?
Use Cisco IOS commands under the serial interface and pseudowire class configuration modes, specifying encapsulation, clock source, payload type, and QoS profiles.

End-to-end latency is typically under 5 ms with optimized QoS and proper network provisioning, ensuring carrier-grade performance.
How does the module handle Quality of Service (QoS)?
It leverages Cisco IOS QoS features including classification, queuing, traffic shaping, and prioritization to guarantee low-jitter, low-loss transmission.
Does the NM-CEM-4SER support redundancy?
Yes, it supports pseudowire redundancy with bidirectional forwarding detection (BFD) and unequal cost load balancing for high availability.
What is the power consumption of the NM-CEM-4SER?
The module consumes approximately 20 W under full load, subject to platform-specific power budgets.
