2.1 Functions

2.1.1 VoIP Function

VoIP achieves the goal of voice communication in IP network by encoding and

digitizing voice signals first, processing them into compressed frames then and

transforming them into IP packets for transmission at last. VoIP has increased

utilance of network bandwidth greatly and reduced communication costs largely.

And its wide use also fastens development of broadband multimedia application.

Greatest advantage of VoIP is that it can make full use of Internet and global IP

interworking circumstance to provide more services better than traditional services.

With built-in VoIP function, AN3300-01 changes TDM voice into IP packets by

adopting standard voice codec technology. And softswitch equipment performs call

control. Therefore AN3300-01 as access media gateway can be used in

combination with softswitch equipment for networking, to provide VoIP access to

analog subscriber lines and meet carrier-class QoS, management and operation

requirements. Plus softswitch equipment AN3300-01 can support VoIP services as

the following:

Support IP telephone access of POTS subscriber;

Calling line identification presentation and calling line identification restriction

(CLIP and CLIR);

Call waiting;

Three party services;

Alarm clock service;

Call forwarding (Unconditional, Busy or No Answer);

Immediate hotline;

Outgoing call barring (OCB);

Distinctive ring;



Support fax service based on T.30/T.38 protocol;

Support pulse accounting and pole-reversing accounting;

IP CENTREX service;

AN3300-01 VoIP part has the following main functions:

Support two protocols: ITU-T H.248 and MGCP;

Call processing capability: 25K BHCA;

Call completing rate greater than 99.999%;

Able to realize 256channels of VoIP calls simultaneously;

Support ITU-T G.711a/G.711 u/G.723/G.726/G.729 speech encoding;

Support silence compression and comfort noise generator function;

Support echo suppression function;

Support multiple MGC list;

Support 802.1q VLAN and priority configuration of each channel of voice.

2.1.2 Layer 2 Switch Function

AN3300-01 supports all layer 2 switch functions as specified below:

VLAN

VLAN technology allows network administrator to logically set a physical LAN to

different broadcast areas or virtual LANs, namely VLANs. Each VLAN contains a

group of workstations with the same demand and has the same attribute as that of

physically formed LAN. Broadcast and unicast traffic within a VLAN will not be

forwarded to other VLANs. That helps to traffic control, cuts equipment investment,

simplifies network management and improves network security. AN3300-01

supports the following VLAN functions:



Port-based VLAN

Port-based VLAN refers to the VLAN policy of setting a port or a group of ports

to a VLAN. Each port can be set only to one VLAN. And ports of different

VLANs cannot communicate directly in layer 2. Instead the communication

should be realized through router between VLANs.

IEEE 802.1q-based VLAN

IEEE 802.1q-based VLAN refers to the VLAN policy of distinguishing VLANs

according to VLAN ID indicated by VLAN tag. Generally it’s used in multiple

VLANs over multiple equipments. AN3300-01 supports identification of tagged

message and the operation of adding tags to untagged message.

Combined VLAN policy based on both port and 802.1q

This policy integrates port-based and 802.1q-based VLAN characteristics.

Port-based VLAN is used in ports of terminal user and IEEE 802.1q-based

VLAN is used in connections between equipments.

VLAN Trunk

VLAN Trunk function is used in connections between equipment. It can realize

multiple VLANs over a port or a group of ports. Multiple VLANs over different

equipments can interwork with the same VLANs of the opposite-end

equipments through such a port or a group of ports. The principle is: to add

different 802.1q tags to the same port or the same group of ports to distinguish

different VLAN message so as to realize VLAN interconnection within the

whole network.

RSTP

STP builds a loopless logic switch topology architecture in the whole LAN by

exchanging BPDU packets between the exchanges. It cuts off some redundancy

paths through certain algorithm to avoid accretion and endless loop of the message

within a loop network. Thus it restrains generation of broadcast storm effectively.



RSTP (rapid spanning tree protocol) realized by AN3300-01 is a betterment of STP.

Its “rapidness” lies in the greatly shortened time delay under certain conditions in

which the root port and designated port enter forwarding status in course of

network equipment or link changes. Thus it shortens time for network topology

stabilization.

Traffic Control

Traffic control function means to control data traffic between the PC and network

node. Such function can reduce discarding or re-transmitting of congestion data

and realize smoothness and evenness of data traffic. And thus it improves

throughput capacity and availability of the network. AN3300-01 can provide the

following traffic control functions:

Avoid decreased throughput capacity and increased transmission delay of the network caused by overload;

Avoid being locked;

Distribute network resources equally.

Port Mirroring

Port mirroring can control transmission status of various ports and perform real

time monitor on data flow in the network. Ethernet interfaces of AN3300-01 uplink

card and XT16 card has port mirroring function, which can be enabled through

NMS configuration.



Port Trunk

Port trunk function is to bind a number of low bandwidth switching ports into a high

bandwidth link (Trunk). And link load is balanced via several ports to avoid

occurrence of link jam. A number of physical ports bound together and used as a

logic port can increase capacity, improve fault-tolerance, balance network load and

increase bandwidth availability. More than that, port trunk can also reinforce

connection availability between equipments. When port of a member of the group

goes wrong or the line is disconnected, data packets can be forwarded

continuously through other ports. Thus it ensures expedite communication of high

efficiency.

AN3300-01 can bind several uplink interfaces of uplink card into a Trunk group. For

example, 2 GE optical interfaces as a Trunk group can not only increase uplink

bandwidth but also provide line protection for uplink ports.

MAC Address Binding and Filtering

MAC address binding and filtering function can solve the problem of users’ illegal

access to Internet by modifying MAC address. AN3300-01 can bind MAC address

to fixed port. By adopting port MAC address filtering mode, each port will only allow

host with bound MAC address to visit the network through it, while access of host

with unbound MAC address will be rejected.



2.1.3 QoS Function

QoS means that the equipment adopts a series of technologies to provide service

of different levels aiming at different user types so that the subscriber obtains the

expected service level. To put it specifically, the network generally places all

applications on equal positions. But to some specially designated applications, for

example bandwidth, time delay, jitter, time delay allowance, packet loss, throughput

capacity, availability and transmission costs etc, the network will provide some

purposeful special services. By lifting priorities in the network, these designated

applications will be processed preferentially. Therefore network QoS for these

special applications is improved. AN3300-01 provides the following QoS functions

as configured by the user:

Control via QoS profile.

Support priority control (on the basis of port, MAC address, IP address and

TCP, UDP ports); support priority mapping and modifying in accordance with

message service type domain and 802.1p; and support differential services.

Support bandwidth control (on the basis of port, MAC address, IP address and

TCP, UDP port No.).

Supports three types of Queue Scheduling Algorithms: Strict-Priority Queue

Scheduling, Weight Round Robin Scheduling and Round Robin Scheduling.

Support packet filtering, redirecting and stream mirroring on the basis of

stream rule.



2.1.4 Multicast Function

Multicast is a network technology which allows one or more senders (multicast

source) to send uniform data packets to more receivers (at one stroke,

simultaneously). Multicast source sends data packets to a specific multicast group

and only addresses which belong to that group can receive these data packets.

Multicast can save network bandwidth greatly because there are only uniform data

packets transmitted in any link of the whole network, no matter how many

destination addresses there are. It’s the most suitable multipoint communication

technology, for the reason that it improves data transmission efficiency, saves

network bandwidth effectively and reduces network load. This technology is widely

used in multipoint communication services such as multimedia conference, remote

instruction, game and simulation and security exchange information real-time

transmission etc. AN3300-01 has complete multicast service functions, including:

Multicast program source management, authority profile management,

multicast program pre-add, multicast program preview and multicast user log;

Support NMS configuration towards multicast service;

Support multi-service under single PVC and multi-service under multi-PVC

and guarantee service QoS;

Support cross-VLAN multicast functions;

A certain port can be designated specially for receiving of multicast channel

services, and some designated specially for receiving of unicast services;

Support equipment concatenated multicast function;

Support IGMP Snooping and IGMP Proxy.



2.1.5 Built-in BRAS Function

As an edge router for broadband converging, BRAS constitutes soul of the

broadband network. It connects broadband access network on one side and

connects IP WAN on the other. Therefore it provides IP services and gains profits

from such services. BRAS fulfills functions of two aspects mainly, e.g. to carry the

network function and to control enabling function. Of them the first is to terminate

user PPPoE connection and converge user traffic; and the second is to enable user

access authentication, accounting and management functions by combining

authentication system, accounting system, user management system and service

policy control system.

AN3300-01 built-in authentication and count functional system provides the

following functions:

Support PPPoE authentication and count functions. Able to terminate 2048 PPPoE sessions simultaneously;

Provide standard RADIUS protocol-based count function, counting on the basis of time or traffic;

Support master-standby switch of authentication & count server.



2.1.6 V5.2 Interface Function

V5.2 interface as a standard and fully open protocol is used to enable cooperation

between the switch equipment and access network equipment. V5.2 interface can

be made up of 1 to 16 2048kbit/s links as needed. It supports all access types

provided by V5.1 interface and has better hub capability. In case of analog

telephone access, V5.2 interface supports not only single subscriber access but

also PABX access. Of them subscriber line signaling can be DTMF or line status

signaling. And it doesn’t have any influence on the supplementary (additional)

services.

Narrowband service interface of AN3300-01 supports V5.2 interface function. At

most it can process 48 E1 interface and 16 V5.2 interface protocols simultaneously.

This interface can be applied to single-subrack equipment networking, or applied to

multi-subrack equipment concatenation for a greater network.

2.1.7 Networking Function

AN3300-01 has variable and flexible networking modes: single-end equipment

networking or multi-end equipment concatenation networking as well as

remote-office end networking. In concatenation networking, AN3300-01 supports

the traditional chain, star or tree topology modes.

2.1.8 Testing Function

AN3300-01 supports testing function as follows:

Support broadband subscriber line testing; namely line grasping function;

Support narrowband subscriber line testing;

Support remote testing on user-end equipment.



2.1.9 Protective Function

AN3300-01 supports hot-plug of various cards and 1+1 master-standby protective

function of core switch cards and protocol processing cards. When receiving the

information of master card failure, standby card will set itself to “working” mode,

send out switching alarm and take over tasks of the master card. It’s unnecessary

to change connection of uplink interface after the switching; thus it facilitates

maintenance and management operations of the user greatly.

Adopting parallel connection of dual power supply inputs and dispersed power

outputs, AN3300-01 can prevent opposite connection of power supply. Power

supply and ring current of all cards are provided separately. Failure of any card will

not affect other cards. Therefore stability of the equipment has been improved

greatly.

2.1.10 NMS Function

AN3300-01 equipment has perfect and powerful NMS functions as described

below:

Support SNMP v1/v2c-based NMS;

Support Telnet remote NMS mode;

Support local NMS through Console serial port;

Support in-band and out-band NMS modes;

Support CORBA interface.

4 System Structure

As shown in the figure above, AN3300-01 adopts double star (IP+TDM) bus

structure. Broadband service part adopts IP (full 1000M GE) bus structure. And

various broadband service cards are connected through IP bus. Broadband service

switching is fulfilled in core switch card. Two core switch cards have

master-standby switch function. Narrowband service adopts TDM (8Mbit/s) bus

structure. And various narrowband service cards are connected through TDM bus.

For narrowband service, master-standby switch function is realized by two protocol

processing cards. Such master-standby switching is performed respectively for

broadband service and narrowband service and has no influence on each other.

This double star bus structure ensures private line connection between service

modules and central processing modules and avoids bandwidth bottle-neck. It

makes control of data security, traffic and priority much easier.

4.2 Hardware Structure

7 Network Management System

This chapter gives specifics about four management functions of AN3300-01 NMS,

NMS categories and networking modes, mainly including:

Configuration management

Failure management

Performance management

Security management

CLI NMS

GUI NMS

Networking modes



7.1 NMS Functions

AN3300-01 NMS boasts four management functions, i.e. configuration

management, fault management, performance management and security

management.

7.1.1 Configuration Management

Configuration management means to configure interface parameters of ports of

network side or user side, such as interface type, VPI/VCI value, access rate of

subscriber port; as well as service channel parameters such as subscriber ports

associated with the service channel. When a new card is added to the equipment,

NMS can detect new hardware automatically and notify the user for confirmation.

NMS can also save all configurations of the equipment and load automatically in

case of the system re-start or service card re-start.

7.1.2 Fault Management

Fault management means to perform realtime monitor on abnormalities of the

equipment and network path and fulfill tasks including alarm signal monitor, report,

storage and fault diagnosis, location and treatment etc. The user can judge faults

and take measures in the shortest time according to alarm codes shown by NMS,

to isolate and correct the faults and resume the affected service. Fault

management includes mainly the following functions: current alarm view, analysis

and fault location and historical alarm management etc.


7 NMS

7.1.3 Performance Management

Performance management means to collect and do statistics towards practical

operational quality data of the equipment so as to monitor state and performance of

the network and the equipment and offer appraisal, analysis, precast and layout

basis to maintenance engineers. Performance management includes the following

functions in general: collect and do statistics to performance values of key objects

such as the user, network port and PVC etc.

7.1.4 Security Management

Security management refers to security examination on operators’ access to NMS

to avoid access of unauthorized operators to network resource and the equipment.

It concerns all management functions. Security management includes mainly the

following functions: user level and authority management, access control, data

security and operating log management etc.



7.2 NMS Classification

On the basis of NMS location, NMS can be classified into local NMS mode and

remote logged-in NMS mode.

On the basis of remote management protocol, NMS can be classified into Telnet

mode and SNMP mode.

On the basis of management path, NMS can be classified into inband NMS mode

and outband NMS mode.

On the basis of NMS interface, NMS can be classified into CLI mode and GUI

mode.

These classifications are inclusive to each other. And below is a detailed

introduction taking CLI mode and GUI mode for example.

7.2.1 CLI NMS

CLI is command line NMS. It only needs standard character terminal or PC terminal

program for the user to operate and maintain AN3300-01. CLI NMS is simple to use

and applicable to local management. As for remote operation and maintenance,

Telnet mode can be used. Specific operating method of CLI NMS is as described in

AN3300-01 Equipment CLI NMS Operation Manual.

CLI NMS has the following characteristics:

It provides two CLI-based management modes: serial port super terminal

mode and Telnet mode.

It provides complete user help system. The user can obtain realtime helps in

various ways.

With command memorizing and reproducing function, it can reproduce and

switch execution of a historical command.


7 NMS

It supports shortened commands. CLI interpreter carries out searching

according to the keywords. Input only non-conflicting keywords and the

equipment can recognise the corresponding command.

It controls authority of the user. All commands have authority protection so as

to guarantee access security of the equipment.

The commands are hierarchical. And the directories are divided into root

directories and subdirectories. The commands with their functions correlated

are stored in the same directory.

7.2.2 GUI NMS

GUI refers to ANM2000 developed independently by FiberHome. Adopting NT

operating system and Web style, ANM2000 gives more visualization, straightness,

friendliness and stronger functions. Specific operating method of GUI NMS is as

described in AN3300-01 Multi-Service Access Equipment ANM2000 NMS

Operation Manual.

GUI NMS has the following characteristics:

It’s unified NE-level NMS for all access products of FiberHome. All its

communication protocols, management functions and management objects

comply with relevant standards.

Adopting layered structure and object-oriented design method, it has

outstanding software system structure convenient for adding and expanding

management objects. So it’s easy to operate and able to reduce maintenance

costs.

It adopts an open-type system structure and makes management levels

separate from each other. Simultaneous multitasking can be handled, and

centralized and remote management supported in this system. Along with

network development and upgrade, the user can manage the newly added

system conveniently without influencing the system performance.



With four management functions including performance management, failure

management, configuration management and security management, it can

conduct real-time monitor and control on the system. More than that it provides

reliable security protection policies. Prior to any operations it verifies security

of the user and operated object in various aspects.

It possesses friendly man-machine interface and covers multiple management

levels of TMN. And standard SNMP upstream and downstream interfaces are

provided in this system so as to manage other companies’ broadband access

products with NMS interfaces in conformity to SNMP.
