NAMC-8569-E3/DS3 with E3/DS3 interface

AdvancedMC (AMC) line interface card for MicroTCA (uTCA, MTCA) or AdvancedTCA (ATCA) systems

The NAMC-8569-E3/DS3 is an Advanced Mezzanine Card (AdvancedMC or AMC) with a powerful NXP (Freescale) PowerQUICC III MPC8569 processor that provides DS3/E3 interfaces in next generation systems based on the MicroTCA (MTCA) and AdvancedTCA (ATCA) standards. The TDM-to-ITDM converter connects the onboard DS3/E3 interface with a Gigabit Ethernet port for system interconnect (I-TDM).

The NAMC-8569-E3/DS3 is designed for (tele-)communications applications with a need to aggregate DS3/E3 interfaces, combined with access to switched networks based on high bandwidth Ethernet.

The chipset on the submodule consists of a line interface unit (LIU) from Maxim-Dallas (DS3251) that connects to a multiplexer/demultiplexer chip from PMC-Sierra (TEMUX84) to get access down to DS0 level.

The DS3/E3 framer interfaces to the on-board timeslot interchanger (TSI) chipset. The TSI as well as the TDM-to-ITDM bridge are incorporated in an ECP3 FPGA from Lattice. The TSI allows flexible routing as well as multi-casting of 64kbps timeslots between the various DS3/E3 streams. The TDM-to-ITDM bridge converts the TDM oriented bit stream into Ethernet packets and vice versa.

The MPC8569 device offers a maximum TDM processing capability of 512 64kbps channels.

N.A.T. also offers a variant of the NAMC-8569-E3/DS3, the NAMC-8569-xE1, which provides 8 or 16 E1/T1 lines.
