N.A.T. the specialist in high performance connectivity products for data and communication solutions today introduces the newest member of its PMC telecom product range, the NPMC-STM4.
The NPMC-STM4 is targeted at telecom applications dealing with SDH (Synchronous Digital Hirachie), such as SS7, ISDN or 3G/3.5G mobile applications in optical OC-12/STM-4 and SONET environments.
The onboard add/drop multiplexer/demultiplexer chipset makes the NPMC-STM4 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. high density add/drop or terminal multiplexer as well as edge routers and digital modems or digital cross-connect systems.
The NPMC-STM4 provides one STM-4/OC-12 optical fibre interface on a standard SC-connector at the front panel. The optical transceivers are available for single or multimode fibres.
The very efficient SDH-to-TDM cross mapping functionality enables the user to add and/or drop any of 252 E1 or 336 T1/J1 64kbps payloads of an OC-12/STM-4 SDH/SONET frame. The onboard H.110 TDM bus controller allows flexible switching of 64kbps timeslots of the E1/T1/J1 streams to and from the H.110 bus up to its maximum capacity of 4096 timeslots as well as the selection of one of the E1/T1/J1 clocks as the master clock for the TDM backplane bus. The NPMC-STM4 fully supports the H.110 bus (PTMC) on the PMC I/O connector.
The NPMC-STM4 is a P1386.1/Draft2.1 compatible PMC that can be plugged onto any VME, cPCI or other carrier board offering a PMC extension slot.
