Pre-Owned, Used And Refurbished Cisco NM-8B-S/T

The Cisco manufactured NM-8B-S/T is an eight-port ISDN-BRI Network Module which provides various port densities for ISDN BRI connectivity by allowing users to: query the network module, have traps to monitor the network module, support the ISDN MIB, support plain old telephone service (POTS) call redirection to internal digital modems, and integrate with CiscoWorks and CiscoView management tools. The optional, integrated NT1 allows consolidated customer premises equipment (CPE) to provide multifunction dial access server, router, and other capabilities within power branch office environments.

Four versions of ISDN BRI network modules are available. The NM-8B-S/T includes an S/T interface or an onboard NT1 for each port. Local static RAM (SRAM) is used for buffer descriptors and input queues. When all eight BRI ports run continuous data (144 kbps each) and 50-byte packets, the maximum performance possible is 5760 pps, and an aggregate full-duplex data rate of 2.3 Mbps.

Our extensive NM-8B-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-8B-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-8B-S/T purchase with our standard lifetime warranty. All used NM-8B-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.

Is your interest in the NM-8B-S/T 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.
