Function:

The MA5600 shelf provides different functions through different service boards. This topic provides information about the functions of the MA5600 shelf.

The MA5600 shelf is 10 U high. It provides 16 slots to house various boards. The functions of the shelf are as follows:

·                 Accessing the VDSL2, ADSL2+, and SHDSL services.

·                 Converting the accessed services to IP packets and transmitting them upstream to the IP network.

Working Principles:

The MA5600 shelf consists of Ethernet switching module, control module, service interface module, "MPLS module, "network interface module, and ISU module. These modules support the service access and uplink.

The MA5600 provides ADSL2+, VDSL2, SHDSL services, and IP upstream services through various modules. The MA5600 shelf mainly consists of the following modules:

·                 Ethernet switching module

·                 Main control module

·                 Service interface module

·                 Multiprotocol label switching (MPLS) module

·                 Network interface module

·                 ISU module

Ethernet Switching Module:

The Ethernet switching module is the core of the entire system. It helps in data conversion and protocol handling for the SCU board and service boards.

Control Module:

The control module consists of the SCU board, subboard and related software. This module supports the following:

·                 Control the system and switch services.

·                 Provide the environment monitoring port for connecting the environment monitoring module.

Service Interface Module:

The service interface module consists of the service boards and the related software. It provides various service ports to support:

·                 ADSL2+

·                 SHDSL

·                 VDSL2

·                 ATM(STM-1/IMA/E3)

Network Interface Module:

This module provides the following network ports for connecting to the upper layer network device:

·                 FE optical (electrical) port

·                 GE optical (electrical) port

MPLS Module:

This module consists of the M2GA subboard and the related software.

This module implements MPLS encapsulation for some private line services and forwards them to the IP metropolitan area network (MAN). In this way, the MPLS module offers private line services in the IP MAN.

ISU Module:

This module consists of the ISU board and the related software. It supports the following:

·                 Authentication based on PPPoE, VLAN binding, or VLAN + web (forced portal and embedded portal)

·                 Accounting based on traffic or duration

·                 Providing GE/FE uplink ports
