NAMC-STM1/4

NAMC-STM1/4

Advanced Mezzanine Card (AMC) for Telecommunication Applications

Both the NAMC-STM1 and the NAMC-STM4 are telecommunications interface boards in AMC (Advanced Mezzanine Card) form factor. The NAMC-STM1/4 is targeted at telecom applications dealing with Synchronous Digital Hierarchy (SDH), such as SS7, ISDN or 3G/3.5G mobile applications in optical OC-12/STM-4 and SONET environments.

Being equipped with an add/drop multiplexer/demultiplexer chipset the NAMC-STM1/4 is an ideal single board platform to interface between the frame oriented STM-4/SDH networks and classic TDM (Time Division Multiplex) standards as E1/T1/J1 or E3/T3/J3. Possible applications are i.e. add/drop or terminal mulitplexers.
