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

Cisco's NM-CEM-4SER, or 4-Port Serial Interface Network Module, is a single-wide CEoIP network module with four serial ports that support the following interfaces: EIA/TIA-232; EIA/TIA-449; EIA-530; EIA-530A; V.35; X.21. The NM-CEM-4SER supports both Cisco 12-in-1 interface cables and Cisco Extended 12-in-1 interface cables with user-defined end-connectors permitting connection to either DTE or DCE interfaces. Interfaces and DTE or DCE modes are defined by the type of cable connected to the network module.

Our extensive NM-CEM-4SER 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-4SER. 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-4SER purchase with our standard one year warranty. All used NM-CEM-4SER 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-4SER 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.

Marketing Information

The 4-port Serial 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.
