Larger inner space: more modules can be installed in the cabinet; Design for manufacture and assembly (DFMA) that cuts the structural cost; Neat and modern outlook.
II. Service frame
The MA5100 service frame is 10U in height (including 1U fan frame). Its dimensions (H×D×W) are: 436.0mm×420.0mm×444.5mm, as shown in Figure 2-2.
Figure 2-2 Structure of the MA5100 service frame
The MA5100 can be powered by 110V/220V AC supply or -48V DC supply.
When the AC power supply is adopted, the cabinet is equipped with a built-in primary power module at the top, which outputs -48V DC power. The number of power modules is subject to the requirements on the capacity.
When the DC power supply is used, the distribution box is needed instead of the power module, and the independent -48V supply is led in from outside of the cabinet.
The MA5100 uses fans for heat dissipation. The air enters the frame from the bottom of the frame, passes the boards and exhausts from the top of the frame. There are 48V/0.21A DC fans in the fan frame, and each fan frame can be installed and dismounted independently. Each fan is equipped with a detection terminal to check whether the fan is running normally or not.

Figure 3-1 Functional modules of the MA5100
The backplane is the bridge that connects all the functional modules. The MMX communicates with all the functional modules through the backplane, and implements control, management, and service switching on the MA5100.
The following describes the compositions and functions of the modules.
3.1.1 Main Control Module
This module consists of the MMX board, the subboards and the corresponding software. The module is the core to implement service convergence and switching, as well as device control and management. Its functions are as follows:
I. Service switching and management
The MMX converges the ATM cell flows from the service modules, and transmits them to the backbone network through the broadband uplink interfaces. It also provides interconnection between the service ports of the MA5100 through its service switching function.
The MMX is designed based on ATM technology, and possesses powerful management functions on services at ATM layer. The MMX is able to provide
Technical Manual SmartAX MA5100/5103 Multi-service Access Module Chapter 3 Functions and Service Flow
3-3
QoS for subscribers through congestion management, flow shaping and setting of flow policies.
II. System control, maintenance and management
The MMX controls and manages the whole MA5100 system, and provides alarm management and fault diagnosis for the device. Working with the ESC module, the MMX can monitor the running states of the device.
The MMX supports loading of data and program, and provides Stratum 3 clock for the system.
The MMX supports F4 and F5 Operation Administration and Maintenance (OAM) flows, such as Continuity Check, Alarm Indication Signal, Remote Defect Indication,
and Loopback. The MMX provides maintenance serial port (CON) and Ethernet port (ETH) to
facilitate maintenance from a terminal or the NMS. It also provides a monitoring port (MON) that connects with the ESC module to implement monitoring and alarm management for the device.
III. ATM interface
MMX can provide multiple interfaces through the attached subboards, such as STM-4 optical interfaces, STM-1 optical/electrical interfaces, OC-3c/STS-3c interfaces, E3 interfaces and IMA interfaces.
The first 155M of active/standby MMX uplink interface supports Multiplex Section Protection (MSP) function, enabling SDH line monitoring and protection. When the optical path connected to the first optical interface on active MMX goes wrong, the system will automatically switch the services through this path to that connected to the first optical interface on standby MMX. MA5103 does not support the MSP function.
All the above interfaces support user-network interface and network-network interface.
The MMX board can hold two subboards. Table 3-1 lists all the subboards supported on the MMX.

3.1.3 ADSL Service Module
This module provides ADSL interfaces that are based on telephone lines (ADSL over POTS) and based on ISDN lines (ADSL over ISDN). Working with the ATU-R, it provides ADSL access for subscribers. The ADSL service takes different frequency bands from those used by POTS/ISDN services, so ADSL over POTS/ISDN does not affect normal POTS/ISDN services on the lines.
The ADSL service module consists of the ADSL service process module and the splitter. In actual application, all the upstream signals from the subscribers are sent to
Technical Manual SmartAX MA5100/5103 Multi-service Access Module Chapter 3 Functions and Service Flow
3-6
the splitter, which separates the ADSL signals from the POTS/ISDN signals, and sends the ADSL signals to the ADSL service process module. The ADSL service process module implements Discrete Multi-Tone (DMT) modulation/demodulation on the signals, adapts ATM cell rates, de-multiplexes and multiplexes the ADSL signals, and then sends the data to the CELL BUS. The downstream ADSL service data are sent to the ADSL service process module from the CELL BUS, and become ADSL signals after the process, and then sent to the ATU-R device through the POTS/ISDN lines.
The following table lists all the boards that are supported on the ADSL service module.

3.1.4 LAN Service Module
This module consists of the LAND board, and the corresponding software. This module provides the LAN subscribers with accesses to the Internet and isolates different subscribers through VLAN, so as to provide broadband connection to the Internet and interconnection between leased line subscribers.
In LAN access application, the FE interfaces on the LAND receive the upstream Ethernet frames from the LAN subscribers. After that, the Ethernet frames are encapsulated based on RFC1483 (Bridged) and mapped as ATM cell flow. The ATM cell flow is sent through the CELL BUS on the backplane to the MMX, and sent to the upper-layer network. The downstream ATM cell flow from the CELL BUS is restored into Ethernet frames on the LAND, and then sent to the LAN subscribers.
This module supports:
various Ethernet interfaces like FE optical/electrical interface and GE optical port;
Trunk function on the FE port, in which each group supports the binding of two to four ports;

I. Upstream
ADSL/SHDSL (ATM-based) receives the xDSL signals from ATU-R/STU-R; ADSL/SHDSL converts the xDSL signals into ATM cell flow; In the case of ATM-DSLAM network, ATM cell flow is sent to MMX, then to the
upper layer ATM network through the ATM interface, and implements ATM-DSLAM application;
In the case of IP-DSLAM, the ATM cell flow is sent to LAND where it is converted into Ethernet frame, then sent to the upper layer IP network through the IP interface on the LAND. In this way, the IP-DSLAM application is implemented. When congestion occurs in the network, LAND can dispatch the upstream Ethernet frame based on the set 802.1p priority level, thereby ensuring the IP service QoS.
II. Downstream
In the case of ATM-DSLAM, xDSL service data (in the form of ATM cell flow) are sent to the MA5100 through the uplink interfaces on MMX. The xDSL service data are converted into ATM frames by the MMX, and sent to xDSL;
In the case of IP-DSLAM, the xDSL data (Ethernet frame) is sent to LAND, then sent to MA5100 through the upstream interface on the LAND. Land converts Ethernet frame into ATM frame and sends xDSL through its cell bus. When congestion occurs in the network, LAND can dispatch the downstream Ethernet frame based on the set 802.1p priority level, thereby ensuring the IP service QoS.
After being processed by xDSL, ATM cell flow is converted into xDSL signals, and sent to the remote ATU-R/STU-R.

Figure 3-4 Multicast service flow
When an xDSL subscriber selects a multicasting program, the subscriber terminal sends IGMP packet to the MA5100 and requests to be added into the multicast group for the program;
The LAND on the MA5100 receives the IGMP packet and sends the subscriber information to MMX;
MMX authenticates the subscriber. If the subscriber has the authority, MMX shall send a confirmation to the LAND, so that the xDSL port of the subscriber can be added into the multicast group;
In IP-DSLAM application, LAND receives the video stream from the video server, and broadcasts it to all the xDSL ports; in ATM-DSLAM application, MMX shall send the video stream to the LAND, and the LAND shall broadcast the video stream to all the xDSL ports;
If the xDSL port belongs to the multicast group, the video stream shall be received and sent to the subscriber; if the port does not belong to the multicast group, the video stream shall be discarded;
When the subscriber logs off, the subscriber terminal sends an IGMP packet to inform the MA5100;
When the LAND detects the IGMP packet, the message is forwarded to the MMX, which controls the xDSL to remove the subscriber xDSL port from the multicast group;
LAND is able to send IGMP packets to all the multicast subscribers regularly in order to query the state of the subscribers, and maintain the multicast group according to responses from the subscribers.

Chapter 4 Maintenance Management System
The MA5100 supports two maintenance modes: the command line mode and the NMS mode. The following describes these two maintenance modes respectively.
4.1 Command Line Mode
In the command line mode, the maintenance person can log in to the MA5100 through the serial port or telnet connection to maintain and configure the MA5100.
I. Serial port mode
In the serial port mode, the maintenance person can log in to the maintenance serial port (CON) on the MMX through HyperTerminal, either locally or remotely. The local serial port mode indicates that the maintenance terminal is directly connected to the serial port on MMX of the MA5100. The remote serial port mode indicates that the maintenance terminal is connected to the serial port on the MMX of the MA5100 through a MODEM over a Dial-up connection across the PSTN network.
II. Telnet mode
In the Telnet mode, the maintenance person can log in to the MA5100 through inband or outband management mode.
The outband mode refers to that the maintenance terminal is connected to the maintenance network port (ETH) on the MMX of the MA5100 through IP network. The inband mode refers to that the maintenance terminal is connected to the FE/GE interface of the MA5100 through IP/ATM network, and the maintenance channel occupies a service channel.
Figure 4-1 shows the networking for maintenance through the command line.

The iManager N2000 manages fixed networks in a centralized way through its removable modular application programs. This software system contains platform software, NE management software, network management software, line test management package, and so on.
4.2.2 Characteristics of iManager N2000
The iManager N2000 provides substantial functions to manage the DSLAM devices.
I. Centralized management over different DSLAM devices
The iManager N2000 can monitor and manage Huawei DSLAM series devices (including the MA5100, MA5103, MA5105, MA5300 and S3026V), routers, LAN Switches and other data communication devices in a centralized way, thus simplifying the network maintenance.
II. Centralized monitoring of deivces and traffic statistics
The MA5100 provides diverse access means from broadband access to the Internet, to high-speed leased line interconnection. These access modes are suitable for general subscribers as well as large enterprises, schools, and banks. In this scenario, It becomes a trick how to effectively monitor the running of the network devices and get the traffic statistics at various ports. The iManager N2000 monitors network devices and collects traffics information in a centralized manner, so the maintenance person can trace the performance of a specific device, or devices in the whole network to get the required information in real time. With its performance analyzers, the iManager N2000 also supports analysis on the individual object in a specific time period, and analysis on multiple objects. All the results are output in tables, histograms and graphs.
III. Terminal management
Simplification, maintenance-free, remote management, and auto-detection of rate and distance have become the trend to the development of ADSL terminals. The iManager N2000 supports centralized configuration, test and monitor ADSL terminals using RTU protocol.
IV. Broadband test management
The iManager N2000, with a built-in broadband test management system, tests the xDSL lines by controlling the built-in broadband test module or outer test equipment of the MA5100. It also analyzes and processes such test data. The test results are not
Technical Manual SmartAX MA5100/5103 Multi-service Access Module Chapter 4 Maintenance Management System
4-4
only the basis to provide xDSL service, but also used to locate the failure that occurs on the subscriber line or the central office side so as to save the troubleshooting time.
V. Batch processing on services
With the popularization of ADSL services and increasing of group users, allocating service indexes and configuring service parameters become time-consuming. The iManager N2000 supports processing of ADSL services and PVCs in batches. It also provides service configuration templates to reduce the burden in inputting the configuration parameters. Such processing functions of the MA1500 reduce the time to deploy the service.
VI. Centralized backup and loading of device data
The iManager N2000 provides the Data Center management software for centralized backup and loading of data of all the devices in the network. The maintenance person can use the Data Center software to make manual or timed loading and backup for all the network devices or a specific device. The centralized loading function also makes it possible to implement batch upgrading of software for the ADSL devices in the network segment.
VII. Safe solution to NMS and NMS database
There are very strict requirements on the security for the NMS and NMS database. The iManager N2000 provides the NMS database backup tool to back up and restore entries in the NMS database. The tool supports manual and periodic backup and manual restoration. Remote monitor terminals are also available in the iManager N2000 to supervise the status of the status and the NMS database.
VIII. Complete fault management and fast fault locating
The iManager N2000 supports the following functions:
Real-time monitoring on alarms Query of history alarms Sorting and counting of alarms Dumping of alarm information Filtering of alarm information E-mail notification of alarms Analysis of alarm dependency Trap check
The alarm correlation analysis enables the maintenance person to pinpoint the faults very quickly. The iManager N2000 also supports switching from alarm topological window to alarm window and from alarm information to faulty port. This simplifies the troubleshooting process.
Technical Manual SmartAX MA5100/5103 Multi-service Access Module Chapter 4 Maintenance Management System
4-5
IX. Modular design and smooth upgrading
The modular and pertinent design of the iManager N2000 software packages enables the carriers to make purchase of the management packages to their own needs. The iManager N2000 supports smooth upgrading to cope with the demand to manage new devices and new services in future.
X. Sophiscated security management
The iManager N2000 offers management authority and operation authority to the devices. The management authority specifies whether the maintenance person can manage a specific device or not. If a device is beyond the management authority of a maintenance person, the node of such device is not available for the user in the topological view. The operation authority can be made more specific to reach the ports of a device. The operation authority is further classified into readable and writable authorities. This hierarchical management mode makes the iManager N2000 a right solution to managing small and medium-sized DSLAM networks, and to future NMS development as well.
XI. SNMP interface to access the third-party NMS
The iManager N2000 provides the basic functions to manage DSLAM networks. It also provides the maintenance means to simplify the service flow and reduce the complexity of operations. Its centralized and hierarchical management functions ensure the security in the NM operation, and reduce the investment in NM systems. As for large-sized DSLAM networks, the iManager N2000 can provide hierarchical NM solutions together with iManager N2100 of Huawei.
4.2.3 Graphic User Interface of iManager N2000
The iManager N2000 provides friendly Graphic User Interfaces (GUIs) with unified style to make the network management operations simple and easy. It also provides powerful help system to assist the maintenance persons to learn and get familiar with the system.
The iManager N2000 network topological view and the panel view of the MA5100 in the NMS are given below to further illustrate the operability of the iManager N2000.
I. Network topological view
The iManager N2000 provides network topological views and submaps which are identical with actual network topology, as shown in Figure 4-2.

4.2.4 iManager N2000 Networking
The iManager N2000 supports networking with the MA5100 through inband, outband or hybrid modes.
I. Inband networking
Inband networking is to manage a device through the service channel provided by the managed device. In this networking mode, NM messages are transferred through the service channel of the managed device.
Inband networking is very flexible, and no additional device is needed. However, since the maintenance messages are transferred through the service channel of the managed device, maintenance operation from the iManager N2000 will be impossible when the managed device fails.
Figure 4-4 shows an inband ATM networking of the iManager N2000 system.

In the above figure, the connections between the Network Management Center (NMC) and the ATM switch, and that between the MA5100 and the ATM switch are all in inband mode. The NMC manages and maintains the network devices through the service channels of the managed devices.
As shown in Figure 4-5, NMS sets up PVC maintenance channels using the ADSL dialup access function provided by the MA5100, and implements management through inband connection. However, the reliability of this networking mode is poor, and is only suitable for remote browsing.

Inband networking is very flexible, and the above are only two typical modes. In actual application, NM networks can be flexibly constructed by combining multiple modes.
II. Outband networking
Compared with the inband networking mode, the outband networking mode provides a more reliable service management channel. In this mode, the managed device can be located timely and monitored in real time even though the device fails. In this mode, an additional device is needed to provide the maintenance channel, which is independent of the service channels.
Like the inband networking, the outband networking also supports multiple modes, and the MA5100 NMC supports networking with DDN/ISDN leased line, E1 line, router and LAN.
Figure 4-6 shows an outband networking, in which the NMC connects with the node devices through different ways.

Figure 5-4 MA5100 IP-DSLAM networking
In IP-DSLAM networking, the MA5100 provides the following two applications:
I. External BAS
In this mode, the MA5100 connects with the upper-layer distributed external BAS (also called B-RAS) device (such as the MA5200 series of Huawei), or centralized BAS device (such as the ISN8850 of Huawei). The xDSL subscribers are connected to the IP network through the IP uplink port on the MA5100, and the connection with the BAS is based on PPPoE or other modes, for the purpose of subscriber authentication, authorization and accounting.
Features of a centralized BAS network:
DSLAM access device is connected to the BAS through special convergence device;
The BAS is suitable for initial stages of DSLAM deployment when the subscribers are scattered and the capacity is small;
The BAS device is required to provide large capacity and powerful forwarding capability;
Subject to single point failure and flow bottleneck, difficult in VLAN planning and configuration, the BAS is inapplicable to large DSLAM deployment, causing layer 2 network too large.
Features of a distributed BAS network:
BAS is the convergence device for DSLAM; BAS is applicable to large deployment of DSLAM service; The BAS device is required to provide abundant interfaces and powerful
convergence function;
Technical Manual SmartAX MA5100/5103 Multi-service Access Module Chapter 5 Networking and Application
5-6
With simple network structure, it saves investment by the carriers.
Compared with the centralized BAS network, the distributed BAS network solves the problem of single point failure and flow bottleneck.
II. Built-in ISU
The MA5100 provides a built-in ISU board for subscriber authentication, management and accounting. This board also offers subscribers with accesses to IP network directly.
5.1.4 ATM/IP-DSLAM Hybrid Networking
The MA5100 supports ATM and IP uplinks at the same time. When using the ATM uplink ports, the MA5100 supports broadband access, leased line access, LAN access, and multicast services. When using IP uplink ports, the MA5100 supports broadband access as well as video multicasting (in coordination with upper-layer multicast router or B-RAS device).

5.2 Service Application
5.2.1 High Speed Internet Access
ADSL provides large bandwidth with asymmetric upstream and downstream rates. The maximum upstream rate reaches 896kbit/s, while the maximum downstream rate reaches 8Mbit/s. ADSL makes good use of existing telephone lines for transmission over a distance as far as five kilometers with low deployment cost and a high deployment speed. So, it can satisfy the demands of subscribers in places beyond reach of fibers.
ADSL2+ and ADSL have the same networking mode, but ADSL2+ features in higher rates (max. upstream rate: 1.2Mbit/s, max. downstream rate: 24Mbit/s), and longer transmission distance (6 km).

Figure 5-9 IP DSLAM multicast service application of the MA5100
The MA5100 connects with the IP MAN through its IP uplink interfaces (FE/GE), and coordinates with the upper layer multicasting router or BAS to implement the multicast service. In this application, the MA5100 is a Layer 2 device to implement IGMP Snooping function.
II. ATM-DSLAM multicast service application
In initial deployment of the multicast service, support from the broadband convergence network or the backbone network may be insufficient, or the network devices may not meet the requirement to support multicast protocols. In this case, the DSLAM devices are required to connect with the video service server directly, so as to deploy the multicast service independently. ATM-DSLAM multicast of the MA5100 supports this networking mode, as shown in Figure 5-10.

Figure 5-10 ATM-DSLAM multicast service application of the MA5100
To meet the requirement to connect the multicast server directly, in the IGMP Snooping process of the MA5100, the multicast querying mechanism is introduced. This mechanism is based to send query packets to multicast subscribers at regular intervals, and to maintain the multicast group according to the response packet.
5.2.4 Broadband Test Service
This function aims to test the state of xDSL lines, so as to provide reference for whether or not to activate a subscriber line, or locate the failure that occurs at the subscriber side or central office side.
The MA5100 has a built-in BTSB board for the test purpose, and the networking is shown below.

The maintenance person can use the built-in BTSB to test the states of ADSL lines in the following ways:
log in to the MA5100 through the maintenance serial port (CON) or network port (ETH), and then execute the broadband test command;
use the test management subsystem of the Huawei iManager N2000 NMS to control the BTSB to test the states of the ADSL lines;
connect the carrier’s test system through the NMS, so that the carrier’s test system can control the BTSB to test the states of the ADSL lines.
