details the application of Al Carter's 1850 service transmission platform TSS-5 single board controller function and MSP430 MCU in FIN products. TSS-5 system adopts the MSP4 30 single chip microcomputer as its general single board controller, single board controller is mainly used for monitoring the external voltage, current, detecting the slot number, control panel LED lamp, download the FPGA firmware, external control voltage, monitoring single board latch state and advocate board the communication. Research results show that the MSP430 has been successfully applied in TSS-5, bring a lot of advantages for TSS-5 products, such as high reliability, low power consumption, flexible control architecture, low cost, easy to maintain and upgrade.

PTN is a connection oriented packet technology as the core, at the same time with the end-to-end business management, hierarchical OAM and carrier-class protection transmission characteristics, mainly to the bearing carrier Ethernet, integrated transmission technology is compatible with TDM, ATM and other business.
PTN packet transport network is currently transmitting recognized instead of next generation SDH transmission technology, 1850TSS is an end-to-end PTN transmission smooth evolution of Alcatel-Lucent in response to the mobile IP service development tendency of deterministic and model uncertainties introduced by solution. 1850TSS series of products including the core of a series of different capacity of equipment from access, at present in the domestic market launch is TSS-3, TSS-5, TSS-40, TSS-100, TSS-160 and TSS-640 / 320 and so on several products.
TSS-5 is suitable for TDM / Ethernet hybrid access scenario, can be configured as a STM-4 level of SDH / MSTP and exchange capacity of carrier-class Ethernet / PTN platform of 5G, simulation access support TDM business at the same time, very suitable for mobile base station access application scenarios. TSS-5 is used to select the TI (TI) MSP430 microcontroller (MSP430F5508) as a single board controller with it, and the motherboard communication.
1 MSP430 properties of
MSP430 series microcontroller is the United States of America TI (TI) based on 16 ultra low-power mixed signal processor RISC 1996 began to market (Mixed Signal Pocesso R). MSP430 series single chip not only can be applied to many of the traditional SCM applications, such as automatic control instrument, and the field of consumer goods, more suitable for low-power products some battery power, such as energy meter (water meter, electric meter, gas meter and so on), handheld devices, intelligent sensor, and the need for high performance intelligent instrument equipment.
MSP430 Series MCU will intelligent peripheral, ease of use, low cost and excellent performance of the industry with the lowest power consumption are perfect union is together, can satisfy the requirements of various applications. Key features include MSP430 series mcu:
1) ultra low power (ULP) architecture and highly flexible clock system can significantly prolong the service life of battery;
2) integration of various intelligent peripherals: high performance analog and digital peripherals can greatly reduce the workload of CPU;
3) 16 RISC CPU architecture is simple and easy to use, can be realized with the application of the industry leading code density;
4) complete industrial development environment, TI provides a full set of development tools and technical support.
TSS-5 microcontroller is the MSP430F5508 type, as shown in figure 1. The MSP430F5508 is configured with USB2.0 interface integration, 4 16 timer, 10 bit high performance analog-to-digital converter, 2 serial communication USART (UART, SPI and I2C) interface, hardware multiplier, direct data access (DMA), a real-time clock module with a warning capability, 25 MHz clock, 16K
Flash memory, 6K SRAM and 47 pin.
