Product: VRM-NAMC-STM1/STM4 -

The VRM-NAMC-STM1 and VRM-NAMC-STM4 are telecommunications interface boards in AMC (Advanced Mezzanine Card) form factor for use with an ATCA or uTCA system. The NAMC-STM1 and NAMC-STM4 are targeted at telecom applications dealing with SDH (Synchronous Digital Hierarchy), such as SS7, ISDN or 3G/3.5G mobile applications in optical OC-3/STM-1 or OC-12/STM-4 and SONET environments.

Being equipped with an add/drop multiplexer/demultiplexer chipset both the NAMC-STM1 and the NAMC-STM4 are ideal single board platforms to interface between the frame oriented STM-1 / 4 SDH based networks and classic TDM (Time Division Multiplex) standards i.e. as E1/T1/J1 or E3/ T1/J3. Both boards provide I-TDM functionality on either AMC ports 0 or 1.
