In the iManager T2000V2, there are lot of

terminologies in the configuration and

management procedures. To understand them is

the basic to use the NMS.

Upon completion this course, you will be able to:

Create NE in different ways

Perform basic steps to configure data

Explain the important concepts




Chapter 1 Basic Concepts

Chapter 2 Creating and Configuring NE

Chapter 3 Configuration of Clock and

Orderwire

Chapter 4 Configuration Data Management




Basic Concepts

ID is a unique identifier for one NE in a

network, the corresponding NE can be

found through it.

NE ID is consists of the basic ID andextended ID, eg. NE ID =extended ID ×

256×256+basic ID.

ID is set by physical switch or software in

SCC board. The NEs which have the

same basic ID can be set as different

extended ID via software to differentiate.

The extended ID is 9 by default. Usually

mention “ID” means basic ID.

NE ID and Extended ID

12




Basic Concepts

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

authority so as to control the operator to login NE and configure it.

NE user by default has administrator level, operator level, maintainer level

and monitor level with different operation authority.

One NE user support only one terminal to login NE at the moment.

The default administrator level NE user is “root”

NE User




Basic Concepts

The user with corresponding authority for the T2000

client to login the T2000 server (NM).

NM user is usually under a user group with the

different operation authority. Also can under the

customize authority groups or equipment groups.

The default NM user name is “admin”, which called

super user, it’s authority is more than administrator

user group. It’s password should be keep well.

NM User




Basic Concepts

Gateway NE is the NE that

communicates with the NMS via

Ethernet or serial interface by

TCP/IP.

The non-gateway NE and NMS

communicate each other via the

gateway NE by DCC in the fiber

link.

There is at least one gateway inan NM, but many gateways can

be exist at the same time.

Gateway / Non-Gateway NE




Basic Concepts

Virtual NE is made by NMS to stand for some

unknown equipment, it doesn’t need the real NE on

site to support. Usually, it is used to simulate one

set of NEs or the other vendor’s equipment, alsocan stand for a sub_network.

The data configuration procedure is the same as

the ordinary NE’s.

Virtual NE







Orderwire





Creating NE

Under the NE pre-configuration mode, any change of the data

only saved at the NM side, there is no connection between the

NE in NM with the NE on site, also no on site NE supporting

required.

No query function for the pre-configuration NE.

Usually used for the T2000 operation exercise.

After disable this function, the data saved at NM side can be

execute to the NE on site by download data.

NE Pre-configuration

Creating NE

Sub-rack NE

Generally, one sub-rack NE in

the NMS is corresponding to

one sub-rack with the unique

NE ID on site.

Optical NE

Only for the DWDM site, such

as OTM, OADM, etc. It can be

consist of many DWDM Sub-

rack NEs inside.

Configuring NE

Manual configuration

Configure data step by step, in this way the original

data will be initialized and send new data to the NE.

The previous data and service will lost.

Copy NE data

Copy the data from some other configured NE to the

current one.

The previous data and service will lost.

It got faster speed than other ways.

NE Configuration Mode




Configuring NE

Upload

Get all the running date from

the NE to NM, overwrite the

configuration data saved inthe NE layer on the NM side.

It will keep the running data

and service in the NE.

In the maintenance, operatorshould use this way to

configure the NE in NM or

LCT.

NE Configuration Mode




Configuring NE

Query physical slot

physical slot is based on all theboards now really installed in the

slots of sub-rack.

Query logical slot

logical slot is based on the board

installation data in SCC database. Maybe not consistency with the

physical slot.

Query slots




Configuring NE

The last step of manual

configuration.

SCC board will verify the

new data. After pass, newdata will replace the old

one and run in NE.

Verification is based on

whether the board

installation is right or not.

Verify and Run







Orderwire





Configuration of Orderwire

Call waiting time：Time

for find the calling

destination, if overtime,

busy tone will be send.

Typical value is 9 or 5.

Dialing mode：only

support the DTMF.

Orderwire data setting




Configuration of Clock

No protection setting

Set clock source priority

only

Clock protection setting：

Set clock source priority

only

Set clock subnet. (enable

the SSM protocol)

Two Type of Setting




Configuration of Clock

Clock ID

The lower 4 bits of S1 byte stand for the quality of clock ,

the higher 4 bits of S1 byte are unused, so Huaweicompany define the 4 bits as clock ID, that can avoid the

clock traced loop.

Standard SSM protocol

Fully comply with the ITU-T recommendation.

Extended SSM protocol

Not only comply with the ITU-T recommendation but also

support HUAWEI clock ID definition.

Clock Concepts







Orderwire





Configuration Data Management

Check the consistency of the configuration data between

the NM side and the NE side.

For the different part，use upload/download to handle.

It will not change the current data, recommend to useperiodically.

Consistency check

Upload: data load from running NE to NM.

Download: data load from NM to NE.

Upload/download





Only delete the configuration data of the selected NE at the

NM side, the data still exist in the NE.

After initializing, NE icon in NM change to unconfigured

status.

Initializing NM side data

Import：configuration data from script file to NMS.

Export：configuration data from NMS to script file.

Can be used in the T2000 upgrade procedure.

Import/export script file





Synchronize all the NE time to the T2000 server time.NE time synchronization

Use for the automatic loopback release. To avoid the problems after circuit

recovery.

Function include：

VC3/VC4/optical interface/electrical interface loopback.

Ethernet/DWDM channel loopback.

Laser shutdown

Automatic disabling of NE function




Questions

What is the difference between physical slots and logical slots？

What is the function of the NE pre-configuration？

What is the difference between manual configuration and upload？

What is the difference between standard SSM protocol and extended

SSM protocol?




Summary

We have mentioned these basic terminologies in this course:

Gateway NE and non-gateway NE

NM user and NE user

Manual configuration, upload, copy NE data.

Pre-configuration NE.

Physical slot and logical slot.

Two type of the clock setting and the concepts in clock setting.
