Questions & Answers
What is the NM-CEM-4TE1 Cisco router network module?
The NM-CEM-4TE1 Cisco router network module provides four T1/E1 ports for circuit emulation over IP, enabling legacy TDM services on packet networks.
How many T1/E1 ports does the NM-CEM-4TE1 support?
It supports four independent T1/E1 ports, each delivering separate circuit emulation sessions over IP.
What is Circuit Emulation over IP (CEM)?
Circuit Emulation over IP encapsulates TDM streams into IP packets, preserving timing and transport of T1/E1 circuits across packet networks.
Which Cisco routers are compatible with the NM-CEM-4TE1 module?
It is compatible with Cisco ISR 4000, 3900, 2900, and 2800 series routers with available NM or SM slots.
How do I install the NM-CEM-4TE1 network module?
To install, power down the router, insert the NM-CEM-4TE1 into a valid module slot, secure the module, and restart the router; the system will auto-detect the module.
What Cisco IOS software version is required for NM-CEM-4TE1?
Use Cisco IOS XE 16.3 or later; this version includes the necessary CEM feature set and module support.
How does the NM-CEM-4TE1 handle latency and jitter?
It uses adaptive jitter buffers and QoS prioritization to minimize latency and jitter, ensuring reliable TDM service delivery.
Does the NM-CEM-4TE1 support synchronization standards?
The module supports IEEE 1588v2 and Synchronous Ethernet (SyncE) for accurate clock synchronization of emulated circuits.
What bandwidth is needed for each T1/E1 circuit on NM-CEM-4TE1?
Plan roughly 1.9 Mbps per T1 circuit and 2.5 Mbps per E1 circuit, accounting for payload and IP/UDP overhead.
Can the NM-CEM-4TE1 be used for voice and data services?
Yes; it supports voice and data TDM services such as PBX trunking, ISDN, and leased lines over an IP backbone.
What are the key performance benefits of NM-CEM-4TE1?
Key benefits include lower WAN costs, centralized management, and efficient T1/E1 consolidation on existing IP infrastructure.
Is redundancy supported with the NM-CEM-4TE1?
The module supports path and control plane redundancy via multiple WAN routes and HSRP/VRRP integration.
How is T1/E1 clocking configured on the NM-CEM-4TE1?
Configure clock source and recovery under the interface using IOS commands like "clock source line" and "cem timing profile".
What configuration steps are required to set up circuit emulation?
Setup involves defining T1/E1 interface parameters, creating CEM profiles, mapping timeslots to packet streams, and applying QoS policies.
Where can I purchase the NM-CEM-4TE1 module?
Purchase through authorized Cisco partners, distributors, or the Cisco online store using SKU NM-CEM-4TE1.
How does the NM-CEM-4TE1 improve network scalability?
By aggregating multiple TDM circuits onto IP links, it simplifies network expansion and avoids additional physical lines.
