DCN Commissioning Solution Introduction Through third-party networks

Solution Description Advantage Disadvantage Priority

Through service

channels provided

by the customer

The customer provides the Ethernet or E1 (or N x 64 K)

channels, and NMS information of Huawei is directly

connected to the third-party Ethernet port as common

services or connected to E1 channels through the protocol

converter/clock port.

The interface of Huawei is

simple, involving no

cooperation with third-party

equipment.

The service channels of the

customer are occupied.

Transparent

transmission

through

synchronous

ports or

asynchronous

ports

The third-party equipment is required to provide the

synchronous or asynchronous data ports. Then, information

is transmitted transparently through the third-party

microwave equipment. Finally, information is converted back

to Ethernet NMS information through the protocol converter.

The NMS can also be connected to the third-party

equipment directly.

Service channels are not

occupied.

1. Special connectors need

to be prepared. 2. The

cooperation of the third party

is required, which is very

risky.

2

Through the IP

protocol

The NEs of the third-party equipment are required to support

IP and NMS ports. NMS information is transmitted in IP

sharing mode.

Acceptance Strategies

1. The operations must be strictly compliant with the Acc eptance Guide.

2. The acceptance consists of two parts, namely, Acc eptance I tems and Form(Recommended)and Acc eptance I tems and Form (Opt ional).

3. It is recommended that the items to be tested should be selected only from the

Acc eptance Items and Form (Recomm ended)and the items should be as few as

possible. If the customer has special requirements, a few items that can be tested

can be selected from theAcc eptance Items and Form (Opt ional).

4. Before the acceptance, acceptance items and operation instructions that

correspond to these items should be printed based on the selected items,

combined into a manual, and submitted to the customer. The manual submitted

to the customer cannot consist of items not to be tested and corresponding test

instructions. It is prohibited to submit the unedited Acc eptance Guideto users.

5. The items selected from the Acc eptance Items and Form (Opt ional)need to be

quoted and charged separately.

6. Recommend remote acceptance to customers. It is recommended that the

percentage of items subject to on-site acceptance be 5% - 10%.

Acceptance Online Test Methods of Ethernet Services

Online test methods of Ethernet services: The ETH-OAM function is used for testing Ethernet services.

Prerequisite: Antenna alignment is completed. The RTN605 V100R300 or RTN620 V100R300 is configured

with the EMS6.

1. Select the NE from the Object Tree in the NE Explorer of the NE1, and then choose

Configuration > Ethernet OAM Management > Ethernet Service OAM Management

2. Select the MD, MA, and MEP that correspond to Port 1, click OAM.

3. Select Start LB.

The LB Test window is displayed. .4. Select MP ID, and set the parameters in Test Node.

5. Click Start Test.

6. Check Detection Result.The LossRate in the Detection Result should be 0.

Procedure:


34/42


Acceptance AM Test Method of testing the AM handover function: If the hybrid microwave is used for transmission, whether the

handover function is normal can be verified by testing the AM handover function.

Prerequisite: The antennas are aligned. The HYBRID/AM mode is configured.

Disable the AM function.

Enable 15-minute performance monitoring.

Query the performance: No FEC-BER-COR-

ER, and only the low modulation mode is

available. Enable the AM function.

Query the performance: No FEC-BER-COR-

ER exists. It can be found that the modulation

modes is adjusted from low to high.

Procedure:

Notes:

1. The two ends of the link must beconfigured synchronously.

2. This method is not the same as the

method of decreasing the optical power

described in the Commiss ion ing Guide.

This is better. The Commiss ion ing Guide

will be modified later.

Reclaiming Licenses Strategies and requirements for microwave licenses

Due to the uncertainty of microwave network planning, delivery based onBTSs is impossible. Therefore, under the microwave strategy, the Supply Chain

delivers the maximum number of licenses. The GTS is in charge of reclaiming

the frontline licenses. For projects delivered by customers, customer support

engineers should mark them clearly and the Supply Chain delivers the licenses

as planned.

During the engineering implementation or before preliminary acceptance, GTS

engineers reclaim licenses according to the actual license capacity in the orders.

GTS engineers download license files of the corresponding capacity from the

support website of Huawei, load them on the site or remotely through the DC

software, and then click the files to activate them.

Entry to CEAS In 2008, the Network Product Technical Service Dept issued the Notice on

Requirements for Entry of Information Ab out RTN Microwave Customer

Equipment to CEAS, clearly requiring that engineering information about RTN

microwave should be entered to CEAS in a timely manner.

The requirements and mode of entering homegrown products to CEAS should be the same

as those of other products. After a project is completed, related data needs to be entered in

CEAS. For entry criteria and operation methods, see the appendix to the Notice.

For RTN microwave engineering projects completed in 2008 or earlier, all missing data

should be entered in CEAS in Q1 of 2009.

The network product manager of the technical service department at each representative

office is the first owner for entering and supplementing data about homegrown microwave

in CEAS. The product manager designates microwave engineers to complete the entry.

Currently, CEAS features low entry rate, low accuracy, and poor availability, which

seriously affects the follow-up implementation of services. To improve the data entry rate

of CEAS and enhance the timeliness and accuracy of CEAS data entry, the Network

Product Technical Service Dept reiterates that:

Repair and Return of Damaged Boards

Currently, there is a large number of OEM parts, especially ODUs, are not returned. This situation

seriously affects the analysis of fault causes and improvement of product quality of Huawei.

If the damaged boards (especially ODUs) are not returned in a timely manner, the vendor may delay the

replenishment.

The purchased microwave or ODU damaged within the warranty, especially at the engineering stage,

should be timely returned to vendors for repair, thus avoiding expensive maintenance costs caused by

the repairs and returns beyond the warranty period.

In March 2009, the process for handling damaged microwave ODUs was issued to the

frontline for trial use. Representative offices and project teams need to return damagedparts and purchased parts as required.

Strategies for Spare Parts


41/42


Strategies for Spare Parts

Key strategic points of homegrown microwave spare parts:

The number of microwave spare parts to be sold is 3% - 5% of that of microwave spare

parts to be installed. GTS engineers should control the sales of microwave spare partsto customers effectively.

The HQ does not store spare parts for OEM microwave or purchased equipment such

as ODUs and antennas.

In principle, representative offices are not allowed to store microwave spare parts,

especially OEM equipment such as ODUs.

For managed services and replacement of spare parts, representative offices can store

a certain number of IDU and ODU spare parts according to the lowest requirement.

The HQ should review and approve the applications of representative offices for spare

parts in strict compliance with related service contracts and service SLAs. The OEM microwave and OEM spare parts applied for by representative offices shall, in

principle, not be returned to the HQ (the method of handling the returned equipment or

spare parts is unavailable).
