Product Overview

SmartAX MA5633 distributed converged cable access platform (D-CCAP) coaxial media  converter (CMC) device is a full-service, highly intelligent digital cable network device designed for  fiber deep migration. Installed at the edge of an HFC network, the MA5633 delivers a Gigabit  bandwidth to a group of users at a lower cost than traditional HFC with centralized CMTS and FTTH.  With SmartAX OLT located at the head end aggregates up to several hundreds of distributed MA5633s.  This solution provides space, power, and cooling efficiencies required for a large-scale transition  toward fiber deep architectures. Positioning to support the SDN framework, the D-CCAP further  evolves HFC.

Product Specifications

Product Highlights

High Bandwidth:

 Complying with the European standard, supports a maximum downstream rate of 1600 Mbit/s in  QAM 256 mode and a maximum upstream rate of 300 Mbit/s in QAM 64 mode.  

 Complying with the U.S. standard, supports a maximum downstream rate of 1280 Mbit/s in QAM  256 mode and a maximum upstream rate of 300 Mbit/s in QAM 64 mode.

Converged Services:

 Utilizing Huawei’s MA5800 OLT platform, both MA5633 and fiber to the home (FTTH) devices  can share same platform for provisioning platform. 

 Supports L2VPN business services over DOCSIS (BSoD). 

 Dot1Q-based and Dot1ad-based L2VPN services 

 MPLS-based L2VPN service (An OLT model MA5800 is required.) 

 Provides an integrated solution for video and data services using a built-in EQAM, which  simplifies network deployment.

Simple Maintenance and Management:

 Supports centralized management. In this mode, the MA5633 is plug-and-play and regarded as  a service board of the OLT. Simple and efficient maintenance and operations are performed on  the OLT. The OLT supports remote configuration, upgrades, and O&M of the MA5633.  

 Supports Internet Protocol Detail Record (IPDR), an efficient data statistics and reporting  mechanism used for accounting, fault locating, and network running status monitoring purposes  to meet routine O&M requirements.

Supports upstream spectrum scanning. Upstream cable channels are prone to interference from  external noises, which adversely affect CMs and user services. 

 Supports upstream spectrum scanning and its file storage for maintenance analysis.  

 U2000 supports upstream spectrum scanning. Spectrum range from 0–102 MHz supports  quiet noise scanning. The sampling is performed at an interval of 100 ms and step of 50  kHz.  

 Supports proactive network maintenance (PNM): Before a network fault adversely affects user  services, the fault diagnosis system connected to the MA5633 detects this fault based on the  analysis on the pre-equalization coefficients obtained between CMs and the MA5633. This  function provides a preventive maintenance mode which decreases actual faults greatly,  thereby reducing network O&M costs and improving carriers‘ service level agreement (SLA). 

 Supports maintenance using mobile Apps. Using mobile Apps, CMCs, cables, and CMs can be  maintained, and the following information can be queried: CMC statuses and locations,  downstream and upstream channel parameters of cables, MAC and IP addresses of CMs, and  working channels of CMs.

Application Scenarios

 Provides the HSI, VoD, IPTV, and dynamic voice services for residential users to meet multiple  service operators (MSOs)' service requirements. 

 Provides the L2VPN/L3VPN BSoD service for enterprise users. (An OLT model MA5800 is  required.) 

The MA5633 supports PON and GE upstream transmission. In the following networking application,  the GE upstream transmission is used as an example.

Typical D-CCAP networking of the MA5633:

D-CCAP Network Structure

A D-CCAP network consists of an OLT, CMCs, and a U2000 network management system, complying  with the remote MACPHY architecture requirements specified by CableLabs DCA (Distributed CCAP  Architecture). 

 OLT: an aggregation device that terminates the PON protocol and locates in a central office  (CO).  

 CMC: forwards data signals at Layer 2 between the upper-layer network and the HFC network.

 U2000: virtually manages and maintains NEs and services in the D-CCAP network.

Product Appearance

Uplink optical port: provides two uplink ports, which can be GPON/GE port, which uses a small  form-factor pluggable (SFP) module.  

RF out port: British-standard F connector.
