NAT-MCH

Overview
The NAT-MCH is a MicroTCA (uTCA/MTCA) Carrier Hub in the form factor of a single or double width, mid- or full-size Advanced Mezzanine Card (AMC). It provides the central management and data switching entity for all MicroTCA systems. The NAT-MCH comprises of a base module and numerous optional daughter cards which can be mounted on the base module. The NAT-MCH is MTCA.0, MTCA.1, MTCA.2, MTCA.3 and MTCA.4 compliant and delivers switching and hub functionality for the various system fabrics as defined in the AMC.x standard series or custom protocols based on Xilinx Kintex-7 FPGA.

CPU, memory and O/S
The NAT-MCH base board is equipped with a CPU of the Freescale ColdFire family of processors. The CPU operates at core frequency of 266 MHz. The NAT-MCH provides 32/64MB SDRAM and 16/32/64MB FLASH memory. The NAT-MCh operates on the field proven real-time kernel OK1.

Gigabit Ethernet Switch and 10GbE (XAUI) Support
The Gigabit Ethernet Switches incorporated in the NAT-MCH both provide a layer 2, non-blocking, low-latency Gigabit Ethernet switches, supporting VLAN as well as a port based rate control. The NAT-MCH supports Fabric A (1GbE) and Fabrics D-G (10GbE, XAUI) according to MTCA.0, MTCA.1 and MTCA.4 and PICMG SFP.1 R1.0, serving up to 13 AMCs as well as the update channel from the second MCH in redundant environments. Also supported are uplink ports at the front panel of the NAT-MCH in order to interconnect to other carriers, shelves or systems.

PCI Express Gen 3 Switch
The PCI Express Switching option allows PCIe Gen 3 connectivity for up to 12 AMCs at PCIe rates from x1 to x4. The PCIe chipsets provide a Quality of Service (QoS) module and are configurable in terms of a non-transparent port for multi-host support. The PCIe option can optionally provide a PCIe clock by a Spread Spectrum Clock (100MHz mean) or a fixed 100MHz clock. The clock can be provided compliant to HCSL or MLVDS signaling levels. The PCIe hub provides clustering support for six independent clusters with one configurable non-transparent upstream port. Each cluster offers its own transparent upstream port.

SRIO Gen 2 Switch
Alternatively the NAT-MCH can be equipped with a Serial Rapid I/O (SRIO Gen 2) daughther board to support uncontended low latency point-to-point connectivity between up to 12 AMC pipes. The SRIO hub supports x1 and x4 fat pipe transport density. A mixture of AMC modules with SRIO Gen 1 & Gen 2 is supported.

NAMC-xE1/T1

Advanced Mezzanine Card (AMC) with 8-, 16-E1/T1 or 4-E3/T3 interfaces

The NAMC-xE1/T1 is an Advanced Mezzanine Card (AMC) in single width, compact-, mid- or full-size format providing access to up to 16-E1/T1 in next generation systems based on MTCA and ATCA standards.
The TDM-to-I-TDM converter connects the on-board E1/T1 interfaces with a Gigabit Ethernet port for system interconnects (I-TDM).
The NAMC-xE1/T1 is dedicated for (tele-)communication applications with extensive need for a high aggregation of multiple E1/T1 interfaces combined with access to switched networks based on high bandwidth Ethernet.
The NAMC-xE1/T1 is used for distributing signaling and payload data to DSP or CPU based processor resources within a MTCA or ATCA system.

– Interfaces at the front panel:
– 8x E1/T1 (NAMC-8E1/T1) or
– 16x E1/T1 (NAMC-16E1/T1)

– Backplane connection
– 2xGbE (port 0 and 1)
– FPGA resource with up to 64-Mbit of Quad Data Rate 2 (QDR2) SRAM
– extensive software support in combination with other N.A.T. AMC boards for any voice/data application in ISDN, SS7, ATM, VoIP or 3G environments.

Advanced Mezzanine Card (AMC) with Freescale dual core QorIQ® P5020
and optional Virtex®-6 FPGA

The NAMC-QorIQ-P50 is the market’s most powerful single-width mid- or full-size AdvancedMC (AMC) processor boards designed around the high-performance Freescale dual core P5020 and optional Xilinx® Virtex®-6 FPGA.
The NAMC-QorIQ-P5020 is designated for today’s packet oriented telecom applications such as LTE or VoIP.

P5020
The P5020 is a multi-core packet processor offering two 64-bit e5500 cores with up to 2.2 GHz. It provides security and pattern match engines, sophisticated buffer and queue management, and additionally various high speed serial data links. Thus, the board is ideally suited for applications in ATCA and MTCA environments. The rich feature list of the P5020 CPU turns the NAMC-QorIQ-P5020 into a state-of-the-art packet processing board.

The P5020 packet processor is accompanied by a set of supporting hardware blocks for time keeping/tracking as well as for external protocol processing/conversion and acceleration.

The best of two worlds: NAMC-QorIQ-P5020-V6
The powerful QorIQ processor in combination with the most advanced Virtex-6 FPGA architecture results in an unrivalled power engine for data and packet processing as well as protocol acceleration. Providing I-TDM support by default, a major part of the FPGA is available for customer use.

Real time clock/PLL
The board is equipped with an on-board Real Time Clock and precision oscillator to support time keeping and time tracking for protocols like RTP (Real Time Protocol) or PTP (Precision Time Protocol, IEEE 1588).

The low jitter PLL allows telecom clocks to be derived from on-board sources and to be provided to the system by the MTCA clock distribution network.

Load Indicators
Each of the two/eight PowerPC cores has its own load indicator LED at the front panel. The load indicators provide a visual feedback of the current load balancing between the individual CPU cores.

Applications Due to the unique combination of the powerful and feature-rich packet processor and the user accessible FPGA, the NAMC-QorIQ is ideally suited to any voice/data application with requirements like deep packet inspection, encryption, protocol conversion or Layer 2-7 routing. The NAMC-QorIQ is the optimal choice for applications like multi-service switches, edge routers, radio network controllers (RNCs), VoIP/VoP gateways and routers as well as mobile network equipment.
