Pre-Owned, Used And Refurbished Cisco NM-4B-S/T

The NM-4B-ST, manufactured by industry leader Cisco Systems, is a four Port ISDN-BRI Network Module designed to provide a multitude of features such as: support the ISDN MIB; integrate with CiscoWorks and CiscoView management tools; enable users to query the network module; support plain old telephone service (POTS) call redirection to internal digital modems; and have traps to monitor the network module.

NM-4B-S/T is supported in all Cisco IOS software releases on the Cisco 2600XM, 3620, 3640, 3631, 2691, 3725, and 3745 platforms. It is supported in 11.3(4)T, all 12.x on the Cisco 2600 platform and 12.0(7)XK, 12. 1T, 12.2 and 12.2T on the Cisco 3660 platform.

Our extensive NM-4B-S/T 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-4B-S/T. 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-4B-S/T purchase with our standard lifetime warranty. All used NM-4B-S/T 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.
