Vectoring Broadband Service Speedup

The MA5616 supports the vectoring function to expand VDSL2 bandwidth for VDSL2 line acceleration. Using VDSL2, users can access networks at a high speed and use diversified services, for example, HD videos, to obtain better user experience.

Flexible Configurations

The MA5616 supports four service slots, mixed insertion of any service boards, and flexible configuration of each port type, increasing the actual installation rate and meeting diversified customer demands. For details about the flexible configuration, see Hardware Configuration.

Combo Boards and P2P Board

The MA5616 has a combo board design for supporting high-density user access requirements. Combo boards reduce carriers' construction expenditure, deployment space, wire setting workload, occupation of the main distribution frame (MDF), and maintenance costs.

The P2P board design meets P2P access requirements for enterprise users and VIP users.

Operational Video Service

The MA5616 uses Internet Group Management Protocol version 2 (IGMPv2) or IGMPv3 to provide IPTV, HDTV, and video conferencing services.

IPv6

The IPv6 feature relieves IP address shortages and is simple to deploy, facilitating smooth service migration from IPv4 networks to IPv6 networks. In addition, IPv6 networks can coexist with IPv4 networks.

Various Voice Services

The MA5616 provides the following voice services and technologies:

• POTS, fax, modem, and ISDN services
• Virtual access gateways (VAGs) that meet requirements of wholesale services or user group-based service management. In addition, the VAGs resolve capacity expansion issues caused by IMS or softswitch capacity limitations.
• Optimized SIP ISDN solution that supports BRA, enterprise private line services, ISDN basic call, fax and modem data services, and ISDN value-added services.
• Voice quality enhanced (VQE) technology that improves the voice quality and user experience
• Dual homing and local switching that improve the voice service reliability
• TDM G.SHDSL access that enables new networks to support existing services without replacing user terminals and affecting user experience.

Highly Effective Management and Maintenance Capabilities

• Plug and play, offline deployment, and onsite software-commissioning-free
• Remote fault locating, troubleshooting, and batch upgrade

Carrier-Class Reliability Design

• Complying with carrier-class reliability specifications
• Having passed the electrostatic discharge (ESD) test.
• Protecting user ports, 4 kV in both common and differential modes for DSL, POTS, and ISDN ports.
• Protecting power:
  • For DC power input: 4 kV in common mode and 2 kV in differential mode
  • For AC power input: 6 kV in both common and differential modes

Appearance

The MA5616 chassis houses six boards and a fan tray. Mounting ears are provided for installing the MA5616 chassis in a 19-inch cabinet or rack.

 NOTE:

The MA5616 appearance varies depending on boards equipped on it. Figure 1 shows the appearance of the MA5616 configured with the CCUE control board, AC-powered. For details, see board introduction.

ESD Jack

Wear an ESD wrist strap when inserting and removing a board. Insert one end of the ESD wrist strap into the ESD jack in the left of the chassis.

Grounding

The MA5616 chassis must be grounded properly so that the lightning can flow to the ground, which improves the capability of the chassis for resisting the electromagnetic interference.

 NOTICE:

• Ensure that the ground cable is connected correctly so that the MA5616 chassis is protected against lightning and interference. The correct connection of the ground cable is an important measure to ensure the human safety.
• The ground resistance of the chassis is recommended to be smaller than 10 ohms. In addition, the national or local standards and specifications need to be referenced.

Connect the ground point on the chassis shell or ground point on the mounting ears to the ground point of the cabinet by using a ground cable for grounding the MA5616chassis. Select one ground method based on the installation scenario.
