flows.

It supports environment monitoring so as to boost reliability and maintainability of

the MA5100/MA5103.

1.2.10 Carrier-Class Reliability

Reliability is taken into full consideration in the MA5100/MA5103 system design,

hardware design and software design.

The main control board MMX supports hot backup and active/standby

switchover. The MA5103 does not support hot backup of the MMX board.

The MA5100/MA5103 supports redundancy hot backup of master frame

subtending board (SEPA) in master-slave subtending mode.

The MA5100 supports STM-1, STM-4, and E3 upstream interface on the active

and standby MMX boards with Multiplex Section Protection (MSP) function to

trace and protect SDH line. The MA5103 does not support MSP function.

With redundancy design (N+1) for primary power supply, the MA5100/MA5103

provides real-time monitoring and alarm functions.

The MA5100/MA5103 has carrier-class capability to handle the abnormalities,

thus ensuring high system reliability.

H66-18: 600 mm 600 mm 1800 mm


17/80


2-2

H66-22: 600 mm 800 mm 2200 mm

Compared with other cabinets, the H66-18 and H66-22 cabinets have these features:

Convenient maintenance: Cabling and maintenance of the boards are performed

from the front side of the cabinet;

Less space occupied: The cabinets can be installed side by side, back to back or

against the wall, which saves the space for the cabinets;

Larger inner space: More modules can be installed in the cabinet.

II. Service frame

The service frame of the MA5100 is 10 U in height (including 1 U fan frame). Its

dimensions (HDW) are: 436.00 mm 420.00 mm 444.50 mm, as shown in Figure

2-2.

Figure 2-2Structure of the MA5100 service frame

The MA5100 can be powered by 110 V/220 V AC supply or -48 V DC supply.

When the AC power supply is used, the cabinet is equipped with a built-in primary

power module at its top, which outputs -48 V 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 -48 V 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 48

V/0.21 A DC fans in the fan frame. Each fan frame can be installed and dismounted

separately. Each fan is equipped with a detection terminal to check whether the fan is

running normally.

The backplane is the bridge that connects all the functional modules. The MMX

communicates with all the functional modules through the backplane, so as to

implement control, management, and service switching of the MA5100/MA5103.

The following describes the components and functions of the modules.

3.1.1 Main Control Module

This module consists of:

The MMX boards

Subboards

The corresponding software

This module is the core to implement service convergence and switching, as well as

device control and management.

Its main functions are as follows.

I. Service switching and management

The MMX converges the ATM cell flows from the service modules, and then

transmits them to the backbone network through the broadband upstream

interfaces. It also provides interconnection between the service ports of the

MA5100/MA5103 through its service switching function.

The MMX is designed based on ATM technology, and has powerful

management functions on services at the ATM layer. The MMX can provide 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/MA5103, 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.

The MMX supports F4 and F5 Operation Administration and Maintenance (OAM)flows, such as Continuity Check (CC), Alarm Indication Signal (AIS), Remote

Defect Indication (RDI), and Loopback (LB).

The MMX provides a maintenance serial port (CON) and an 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 for monitoring and

alarm management of the device.


27/80


3-3

III. ATM interface

The 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 STM-1, STM-4, or E3 ATM upstream interface on the active and

standby MMX boards supports MSP function. The interfaces on the active and

standby MMX boards are connected to different ports on the upper layer

equipment, so as to achieve mutual protection. When an active port on the active

MMX goes wrong, the MA5100 will automatically switch the services through this

port to a standby port on the standby MMX. The MA5103 does not support the

MSP function.

All the above interfaces support user-network interface (UNI) and

network-network interface (NNI). The MMX board can hold two subboards. Table 3-1 lists all the subboards

supported by the MMX.

3.1.3 ADSL Service Module

The module consists of ADSL series boards and the related software.This module

provides ADSL interfaces that are based on telephone lines (ADSL over POTS) and

ISDN lines (ADSL over ISDN). Working with the ATU-R, it provides ADSL access

services 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.Working process

The ADSL service module consists of the ADSL service processing module and the

splitter.

In actual application, all the upstream signals from the subscribers are sent to the

splitter, which separates the ADSL signals from the POTS/ISDN signals, and sends

the ADSL signals to the ADSL service processing module. The ADSL service

processing 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 processing module

from the CELL BUS, and become ADSL signals after the process, and then are sent

to the ATU-R device through the POTS/ISDN lines.

II. Boards

Table 3-3 lists all the boards that are supported by the ADSL service module.

device to provide the function of testing ADSL lines.

3.1.4 VDSL Service Module

The module consists of the VDLA board and the related software. It provides VDSL

interfaces that are based on telephone lines (VDSL over POTS). Working with the

VTU-R, it provides symmetrical high bandwidth (12 Mbit/s) VDSL access services for

subscribers within the range of 11.5 km.

The VDSL service takes different frequency bands from those used by POTS services,

so VDSL does not affect normal POTS services on the lines.


31/80


32/80


3-8

Each VDSL interface supports multiple PVCs, and supports PVC based CAR

flow control at the rate of 64 kbit/s;

3.3 Mhz. The upstream frequency ranges from 4.3 Mhz to 7.9 Mhz.

3.1.5 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; Auto-detection on Straight-through cable and Crossover cable on the ports;

3.2 Service Flow

The following introduces some of the most typical service flows of the

3.2.1 xDSL Access Service Flow

The MA5100/MA5103 provides ADSL, SHDSL, and VDSL accesses.

Figure 3-2 shows the service flow.

xDSL receives the xDSL signals from xTU-R.

xDSL 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


38/80


3-14

interface on the LAND. When congestion occurs in the network, LAND can

dispatch the upstream Ethernet frame based on the set 802.1p priority level to

ensure 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/MA5103 through the upstream 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, and

then sent to MA5100/MA5103 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 to ensure the

IP service QoS.

After being processed by xDSL, ATM cell flow is converted into xDSL signals,

and then sent to the remote xTU-R.

MMX/LAND;

After the process on the MMX/LAND, the LAN service data are converted into

ATM cell flow and sent to LAND;

After the process on the LAND, the ATM cell flow is converted into Ethernet

frame and sent to the LAN subscriber.

3.2.3 Multicast Service Flow

The MA5100/MA5103 supports IP-DSLAM and ATM-DSLAM multicast services, as

shown in Figure 3-4.

When an xDSL subscriber selects a multicast program, the subscriber terminal

sends IGMP packets to the MA5100, applying for joining the multicast group for

the program.

The LAND board on the MA5100 captures the IGMP packets and sends the

subscriber information to the MMX.

The MMX authenticates the subscriber. If the subscriber has the right to watch

the demanded program, the MMX sends an acknowledge message to the LAND

board, so that the xDSL port of the subscriber can be added into the multicast

group.

In IP-DSLAM mode, the LAND board receives video stream from the video

server, and broadcasts it to all the xDSL ports. In ATM-DSLAM mode, the MMXsends the video stream to the LAND board. The LAND board then broadcasts

the video stream to all the xDSL ports.

If the xDSL port belongs to the multicast group, the port will receive the video

stream and sends it to the subscriber. If the port does not belong to the multicast

group, it will discard the video stream.

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.

The LAND board can from time to time send IGMP packets to all the multicast

subscribers in order to query the state of the subscribers, and maintain the

multicast group according to responses from the subscribers.

4-1

Chapter 4 Maintenance Management System

The MA5100/MA5103 supports two maintenance modes: the command line mode

and the NMS mode. The following describes these two modes respectively.

4.1 Command Line Mode

In command line mode, the maintenance personnel can log in to the

MA5100/MA5103 through the serial port or telnet session to configure, manage and

maintain the MA5100/MA5103.

I. Logging in through Serial port

In serial port mode, the maintenance personnel 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 the MMX of the MA5100/MA5103.

The remote serial port mode indicates that the maintenance terminal is connected to

the serial port on the MMX of the MA5100/MA5103 through a MODEM over a dial-up

connection across the PSTN network.

II. Logging in through a Telnet session

In Telnet mode, the maintenance personnel log in to the MA5100/MA5103 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/MA5103 through IP

network.

The inband mode refers to that the maintenance terminal is connected to the FE/GE

interface of the MA5100/MA5103 through IP/ATM network, and the maintenance

channel occupies a service channel.

IV. iManager N2000 software

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 the iManager N2000

The iManager N2000 provides solid 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) in a centralized way.

This simplifies the network maintenance.

II. Centralized monitoring of deivces and traffic statistics

The iManager N2000 monitors network devices and collects traffic information in a

centralized way.

With the support of the iManager N2000, the maintenance personnel 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 period, and analysis on multiple objects. All the results

are output in tables, histograms and graphs.

III. Terminal management

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, supports

tests the xDSL lines. This is made by controlling the built-in broadband test module of

IX. Sophiscated security management

The iManager N2000 offers management authority and operation authority for you to

operate to the devices.

The management authority specifies whether the maintenance person can manage a

specific device. 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.

X. 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 Graphical User Interface of iManager N2000

The iManager N2000 provides friendly Graphical 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.

configuration, management and maintenance on the board or port through theshortcut menus.

You can also configure, manage or maintain the system through the main menus

on the top of the panel view.

4.2.4 The iManager N2000 Networking

The iManager N2000 can be interworked with the MA5100/MA5103 through inband,

outband and hybrid modes.

I. Inband networking

Inband networking is a networking mode through which the NMS manages a device

through the service channel provided by 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.

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

managed devices through different ways.

Figure 5-2MA5100/MA5103 master-slave subtending

Master-slave subtending of the MA5100/MA5103 has these features:

The MA5100/MA5103 master frame and slave frames are connected in a star

topology, so that services on the slave frames shall not interfere with each other. The subtending interface board SEPA in the master frame supports hot-backup

to ensure reliability and safety.

5.1.2 Remote Subtending

Through different interface subboards attached on the AIUA, the MA5100/MA5103

can provide different ATM interfaces for subtending connection with remote

MA5100/MA5103 devices. The system also provides the IMUB board for subtending

connection with remote IMA devices (such as the MA5105).

This remote subtending connection saves the resources of fiber and the ATM port on

the upper layer devices. It also extends the reach of broadband network.
