The main contents

Some basic concepts before use T2000

The steps of configure data in T2000

Some concepts during configure data.


3/26


Upon completion of this course, you will be able to:

Create NE in different ways Know basic steps to configure data

Clear some important concepts


4/26


Chapter 1 Overview

Some relevant concepts

Create and configure NEs

Configure clock and order wire


5/26


Overview

The steps of configure basic data include following items:

Create and configure NE

Configure clock

Configure order wire


6/26


ID and extended IDID and extended ID

ID and extended ID

ID is decided by physical switch in SCC board.

ID is a unique identifier in a network, the data can find corresponding

NE through unique ID.

Extended ID can be set by software.

Usually the extended ID is set to 9 default.

NE user and NM user

NE user

It refers to the user defined at NE, used to assign NE operation

authority so as to control access to NE and configure it.

NE user has such levels as default level, operation level,

maintenance level, system level with different operation authority.

NE user can be classified into LCT NE user, EMS NE user, CMD NE

user and General NE user, which are applicable to get access to NE

by T2000-LCT, T2000, Navigator respectively.


8/26


NE user and NM userNE user and NM user

NM user

It refers to the user of the T2000 client, and the user and his/her

password define the corresponding authority of operation and

management of the NM.

User is usually added in a user group, and enjoys the operation

authority of the user group.


9/26


NE user and NM user

NM user

The default user of the T2000 is admin, which is defaulted a

member of the administrator group, but enjoys more authorities,

called additional authority, than the administrator group, so admin is

also called super user. Super user admin can not be added in anyother user groups and its authority can not be changed.

When using the NM for the first time, the system administrator logs

in as "admin" with the default password. For the sake of security,

the administrator should change the password immediately and

create a new user as required.


10/26


NE and gateway NE

Gateway NE refers to the NE that communicates with the NMS via

Ethernet or serial port line.

The non-gateway NE communicates with the gateway NE via ECC

and communicates with the NMS via the gateway NE.

The gateway NE is a communication route that T2000 must pass

through when managing the entire network.

Gateway NE communicates with NMS by TCP/IP.

There is least a gateway in a NM, but many gateways can be exist at

the same time.


11/26


Virtual NE

Virtual NE means the equipment can not be managed by T2000,

maybe it is a or several NEs, even a subnet that other company

produced.

The data configuration process is the same with ordinary NEs.


12/26


Create NE

Pre-configuration

the configuration data is only stored at the NM, so it will return failure

if you query the data to a pre-configuration NE.

When this option is selected, the configuration will not be sent to NE,

but save at the NM.

For the pre-configuration data that have been debugged in the

T2000, the configuration data is usually downloaded to the NE and

executed.


13/26


Create NE

Subrack NE and Optical NE

Optical Network Element (ONE) is the transport entity that

implements the NE functions (terminal multiplexing, add/drop

multiplexing, cross-connection and regeneration) in a DWDM layer

network. The types of ONEs include OTM, OADM, OLA, REG andOXC.

ONE only exits in DWDM network, in SDH network, the basic entity

is subrack network element.


14/26


Create NE

The ways to create NE

Manual configuration

Configure data step by step, in this way the original data will be

initialized and make new data by the operator to the NE.

so if the data is different, the traffics will be broken

Upload

Report all of the configuration data of the NE to the NM and

overwrite the configuration data saved in the NE layer on the

NM side.

The process is from NE layer to NM layer.


15/26


Create NE

The ways to create NE

Copy NE data

You can use this way to create NE data quickly when the total

net-work have many NE that have the same data.

This configuration way will be faster than other two ways, but it is

demanded that one NE had already configured, so that it can be

as data source.

Notes usually we use upload in maintenance and use manual

configuration in lab.


16/26


Create NE

Physical slot

physical slot means all the boards now in the slots of sub-rack in

fact.

Logical slot

logical slot lie in the database in the SCC board.

It is not the real boards in the sub-rack currently. Maybe the

logical slot are consistency with the current boards in the sub-

rack, may they are not consistency.


17/26


Create NE

Checkout

The step should be implemented when configuration is finished

Checkout is just to check the foregoing configurations are good or

not.

If everything is ok, then configuration is success. the NE is going into

running state.


18/26


Order Wire

Set the order wire before running the equipment, including the following

items: call waiting time, dialing mode, conference call number, 1~3-

channel order wire phone number and order wire phone port

Call waiting time The maximum time that the network look for the

node after the user dial the order wire. Usually it is set to value 9when the network is very large, and it is set to value 5 when the

network is small.

Dialing modeOnly have two modes: pulse and tone, and pulse is

the old technology, now we usually use tone way.


19/26


Clock Configuration

Two ways

Configure clock no protection the steps

Configure the clock source priority

Configure the clock source restoration parameter

Configure clock protection the steps

Configure the clock source priority

Configure the clock source restoration parameter

Configure clock protection subnet.


20/26


Clock Configuration

Configure clock protection subnet

Set clock subnet ID

Start SSM protocol

Set clock ID to the relevant clock source.


21/26


Clock Configuration

Some concepts

Clock ID

The lower 4 bits of S1 byte is set to quality of clock , the higher 4 bits

of S1 byte are idle, so Huawei company define the 4 bits to means

different clock ID, that can avoid the clock traced by itself.

SSM protocol

To start the SSM protocol means to perform clock switching

according to the clock quality.


22/26


Clock Configuration

Some concepts

Standard SSM protocol

Dont use clock ID to implement clock protection function, cant

avoided clock traced by itself.

Extended SSM protocol

Use clock ID to implement clock protection function, can avoided

clock traced by itself.


23/26


Clock Configuration

Some concepts

SSM output control

You can decide whether to output SSM or not as required to avoid

that equipments of different clock subnets affect one another at the

boundary between clock networks.

Clock source switching condition

The clock source switching condition is for deciding whether to

switch the clock source when the equipment fails. After setting a

clock source switching condition, when the equipment detects anydescribed condition, clock source switching occurs.


24/26


Questions

What is the difference between physical slot and logic slot?

What can we do to pre-configuration NE?

Tell the difference of manual configuration and upload.

Describe the steps of clock subnet protection.


25/26


Summary

NE and gateway NE

NM user and NE user

Manual configuration, upload, copy NE data.

Pre-configuration NE

Physical slot and logical slot.

Clock protection subnet and clock configuration.
