Do you know Huawei small-size DSLAM MA5616 and the Highlights? (1)

Huawei DSLAM SmartAX MA5616 Multi-service Access Module (MA5616 for short) is a 2-U high and 19-inch wide board-inserted device. It provides four service slots for flexible board configurations.

The MA5616 applies in fiber to the building (FTTB) and fiber to the curb (FTTC) scenarios. It can also function as a mini-digital subscriber line access multiplexer (DSLAM) or multiservice access node (MSAN). The MA5616 can be installed in corridors or cabinets (indoor or outdoor).

Each MA5616 provides user-to-network interfaces (UNIs), such as ADSL2+, VDSL2, SHDSL, POTS, FE, P2P, ISDN, or combo ports, and two network-to-network interfaces (NNIs) that support autonegotiation among GPON, EPON

Hardware Structure

Commissioning serial port/Environment monitoring port

For the CON port: supports local and remote maintenance, which allows users to configure the MA5616 using software, such as HyperTerminal, through CLI. The default baud rate is 9600 bit/s.

For the ESC port: connects to an environment monitoring unit (EMU), which sends monitored environment monitoring parameters to the MA5616.

Uplink optical port

Supports auto-negotiation among GPON, EPON, and GE. Provides GPON, EPON, and GE upstream transmission or GE cascading. When this uplink optical port is used as a GE port, it is an alternative to the GE electrical (RJ45) port.

Maintenance network port

A 100M Base-T commissioning network port, which is a front-access-cabled FE port and supports 100 Mbit/s full-duplex in auto-negotiation mode.

Clock port

Outputs 2 MHz clock pulse signals.

Environment parameter monitoring port

Can be connected to a sensor to monitor environment parameters.

GE electrical port

Supports 1000 Mbit/s full-duplex upstream transmission or cascading in auto-negotiation mode. It is an alternative to the uplink optical (SFP) port.

Do you know the features of Huawei DSLAM MA5616?

10G GPON Upstream Transmission

• 10G GPON provides a higher bandwidth to meet service requirements.
• The 10G GPON transmission complies with ITU-T Recommendation G.987 and ITU-T Recommendation G.988, and provides asymmetric transmission rates of 2.5 Gbit/s in the upstream direction and 10 Gbit/s in the downstream direction.
• 10G GPON networks can coexist with the current GPON networks to fully use the existing optical distribution network (ODN) resources.

Vectoring Broadband Service Speedup

Huawei MA5616 supports the vectoring technology to increase the very-high-speed digital subscriber line 2 (VDSL2) line rate.

VDSL2 is a mainstream mode for last kilometer access and shows increasing importance in bandwidth usage. VDSL2 uses high frequency bands and therefore the inter-line crosstalk has an evident impact on line quality. The bandwidth in multi-pair access scenario is much lower than the bandwidth in single-pair access scenario. Crosstalk becomes a major factor affecting the VDSL2 performance.

The MA5616 supports the vectoring technology, which uses vectoring groups to jointly transmit signals in the downstream direction and receive signals in the upstream direction of a VDSL2 line. This function of the MA5616 helps cancel the far-end crosstalk (FEXT) and improve VDSL2 line performance.

The vectoring function brings the following values for carriers:

• Increases the bandwidth over a single cable within 500 m by 50% to 90%, reaching 95% of the theoretical value (without crosstalk).
• After rate increasing, carriers can provide higher rates and more types of services for users, such as high-definition video.

NOTE:

Only when the system uses the CCUE control board, the MA5616 supports vectoring broadband service speedup.

Flexible Configurations

The MA5616 supports concurrent working of multiple types of service boards. Numbers of various ports are configured flexibly according to actual requirements, increasing the loading rate and meeting diversified customer demands. For details about the flexible configuration supported by the MA5616

Combo Boards and P2P Board

The MA5616 has a combo board design for supporting a high subscriber density. Combo boards save carriers' construction expenditure, require less deployment space, wiring workload, and time occupancy of the main distribution frame (MDF). Briefly, combo boards reduce carriers' maintenance costs.

• The CALE board has a 32-port built-in splitter and supports service access of 32 asymmetric digital subscriber line 2 plus ADSL2+ ports and 32 plain old telephone service (POTS) ports.
• The CVLC board has a 32-port built-in splitter and supports service access of 32 VDSL2 ports and 32 POTS ports.

The MA5616 provides the following point-to-point (P2P) boards to meet the requirements of P2P access for enterprises and VIP users.

• The EIUD board provides four GE (optical or electrical) ports and four FE optical ports.

Various Services

• Supports Internet Group Management Protocol (IGMP) v2 and v3 to provide IPTV, high definition TV, and video conference services.
• Supports basic voice services such as call, fax, and modem services, and supplementary voice services such as three-way calling, call waiting, call transfer, calling line identification presentation, and calling number restriction services.

IPv6

• Supports IPv6. Compared with IPv4, IPv6 features simplified packet header format, sufficient IP addresses, hierarchical IP address structure, flexible extension header, and enhanced neighbor discovery mechanism.
• Supports IPv6 address management and allocation, IPv6 routing, quality of service (QoS) and security, Layer 2 transparent transmission, and multicast services.

One-Site Deployment and Plug-and-Play

• Is free of software commissioning on site.
• Supports offline deployment and plug-and-play when the device transmits services upstream through a passive optical network (PON) port.
• Automatically obtains configuration data from the iManager U2000 network management system (U2000) and reports its status to the U2000 after going online. The configuration data automatically takes effect.

Zero Touch Routine Maintenance

• Supports fault location through an xPoA command.
• Supports remote fault location and troubleshooting.
• Supports remote acceptance.
• Supports remote upgrade and patch installation.

Carrier-Class Reliability Design

• Complies with carrier-class reliability specifications.
• Passes the electrostatic discharge (ESD) test.
• Be able to start at a -25°C temperature and to work properly for extended periods of time at a temperature as low as -40°C.
• Be able to work properly at a temperature as high as 65°C (temperature at the air intake vent of the cabinet) for extended periods of time.
• Provides surge protection and anti-interference functions.
• Supports user port protection as follows:
  • Digital subscriber line (DSL)/POTS/integrated services digital network (ISDN) ports: complying with K21, 4 kV in common mode and in differential mode
• Supports power protection as follows:
  • DC power: 5 kV in common mode and 3 kV in differential mode
  • AC power: 6 kV
• Uses an anticorrosion design, reduces the wires routed across the surface of the board, and optimizes the heat design by producing a temperature difference to prevent condensation.
