Pre-Owned, Used And Refurbished Cisco NM-CEM-4TE1

The Cisco manufactured NM-CEM-4TE1 is one of two Circuit Emulation-over-IP (CEoIP) network modules (the other being the NM-CME-4SER). The NM-CEM-4TE1, as well as the NM-CME-4SER, supports the CEoIP service offering which is the use of an IP network to provide a point-to-point, bit-transparent data stream between two endpoints. Such a data stream is completely protocol-independent because the network encapsulates and transports, in a continuous stream of IP packets, every data bit presented to an ingress port for delivery to a designated destination port. The data stream is not examined, interpreted, or manipulated in any way. The NM-CEM-4TE1 provides four T1/E1 ports. Depending on the software configuration, all four ports are T1 or all four ports are E1. The NM-CEM-4SER provides four synchronous serial ports.

Our extensive NM-CEM-4TE1 inventory provides for quick order turn-around, often allowing us to ship "same day" or within just 1-2 business days. What's more? As an independent supplier, we are able to offer more equipment options than are available through distribution, including new, used and refurbished NM-CEM-4TE1. In some instances, our pre-owned equipment may still be in new condition, still sealed in original factory packaging (but at a fraction of the cost).

MLCP is committed to quality, and we guaranty any refurbished Cisco NM-CEM-4TE1 purchase with our standard one year warranty. All used NM-CEM-4TE1 equipment is tested to factory specifications and packaged professionally for safe transport. As an experienced supplier of pre-owned network hardware, we understand that we have to be better than the manufacturer, and that fundamental principle guides us every day.

Is your interest in the NM-CEM-4TE1 as a result of an upgrade? We may be interested in your surplus networking equipment and encourage you to take advantage of our flexible "buy-back" options, including an up-front purchase option and generous trade-ins for credit.

General Information
Manufacturer: Cisco
Product ID: NM-CEM-4TE1
Product Description: Cisco 4 Port T1/E1 Circuit Emulation over IP NM
Product Type: Network Module
Marketing Information

The 4-port T1/E1 CEoIP Network Module for the Cisco 2600XM, 2691, 2811, 2821, 2851, 3660, 3700 and 3800 routers provide a new CEoIP service offering. This network modules provide bit-transparent data transport that is completely protocol-independent.

For the first time, this allows network administrators to take advantage of their existing IP network to provide leased-line emulation services, or to carry data streams or protocols that do not meet the format requirements of other multiservice platform interfaces.
