MT90871AV2 Interface - Telecom Application Field And Working Principle

MT90871AV2 is an integrated interface-telecom solution established by Maxim Integrated, an American semiconductor manufacturer. It is a SOC architecture that combines hardware and software, resulting in reliable and cost-effective solutions to meet telecom infrastructure, residential gateways, and industrial data communications needs. It is suitable for multiple technologies such as VDSL2, ADSL2/2+, G.fast, and PON; as well as network access, home gateway areas.

The physical layer of MT90871AV2 is manufactured using Maxim\'s VDSL2 technology, which is capable of supporting up to 100 Mbps download and up to 50 Mbps upload speeds over existing copper lines. This is possible because of its advanced modulation as well as power and echo control features to provide superior range performance. The physical layer is also capable of supporting diverse and multiple technologies such as VDSL2, ADSL2/2+, G.fast and PON. In addition, MT90971AV2 comes with a range of configurable protocols, making it suitable for address various networking needs.

The data link layer of MT90871AV2 provides services like QoS, MAC and PHY isolation, link coding, error control, address and message formats, and segmentation. MT90871AV2 implements the Media Access Control (MAC) layer and Physical Layer (PHY) layer to enable communication in a defined Local Area Network (LAN). Its MAC layer provides network layer device identification and authentication, as well as basic transmission control (e.g. IP address assignment, ARP operation). The PHY layer provides physical interface between the MT90871AV2 and local network in order to enable communication.

The network layer of MT90871AV2 provides services like routing, addressing, FEC and LLID assignment, switches, ETGH and Flow-Control. The routing, addressing, FEC and LLID assignment services ensure efficient data delivery while the switches and ETGH enable efficient quality of service (QoS) and throughput management. The Flow-Control allows easy and fast allocation of resources to meet application needs.

The Session and Presentation layers signifying the upper two layers for M2M communications provide the necessary interfaces for MT90871AV2 to enable device/application interactions. These include protocols like HTTP, SNMP, and FTP, as well as transport layer protocol (e.g. TCP/UDP) and security protocols like TLS, IPSec and AWS. The Session and Presentation layers provide the necessary connectivity for applications to access MT90871AV2, reserving adequate resources for the applications to make use of.

At the Application Layer, MT90871AV2 provides additional features and capabilities to enable secure, reliable, and cost-efficient communications. The Application Layer feature includes support to various Internet of Things (IoT) protocols like MQTT, CoAP, AMQP, and Websockets. In addition, it also provides secure authentication and authorization services to ensure data privacy and security.

To sum up, MT90871AV2 is capable of delivering secure, reliable, and cost-efficient networking solutions for various telecom infrastructure, residential gateways, and industrial data communications applications. It is equipped with various configurable protocols, advanced modulation, and power and echo control mechanism, allowing it to optimize resources allocation and provide higher speeds. In addition, it supports a wide range of technologies such as VDSL2, ADSL2/2+, G.fast, and PON as well as IoT protocols like MQTT, CoAP, AMQP, and Websockets.
