Key PointsCaution Cause Requirement

1 Properly handle the IF board

and SCC power switches.

The field personnel do not know how

to operate the power switches. As a

result, a large number of boards on

the existing network are damaged.

This point must be imparted

to every field engineer,

especially the personnel of

the partners.

2 Do not reseat IF cables

when the power is on.

The ODU and IF board are damaged

by the reseating of IF cables when

the power is on.




the partners.

3 Do not tear up the ODU seal

or remove the ODU cover.

If the seal of the ODU is torn up or

the cover of the ODU is removed, the

vendor will refuse to provide warranty

services.




the partners.

4 Do not damage equipment

with improper operations.

If the damage is caused by artificial

factors, the vendor will refuse to

provide warranty services.




the partners.


Key Points

Properly handle the IF board and SCC power switches.

These boards are damaged due to improper operations of the personnel. Note: So many boards are found damaged in only one project!

① Train microwave partners for standardized operations according to projects.

② Hand out related training materials to every partner and every engineering team.

③ Provide special trainings for the partners with serious problems.

④ Provide effective trainings to all new partners.


Key Points

Do not reseat IF cables when the power is on.

Ensure the power is off before reseating IF cables or IF boards.

Pull IF cables out of the IF board, IF jumper, or ODU or plug into them after the power is off.

IF boards should also be reseated after the power is off.

Be careful in the use of a multimeter for testing the IF output voltage to avoid short circuits.






Key Points

Do not reseat IF cables when the power is on.

Power off the IF board before reseating IF cables.

Reseating IF cables when the power is on tends to cause a short circuit between the -48V power supply and the GND, which will blow out the protection tube.

The picture shows the short circuit.






Key Points

Do not tear up the ODU seal or remove the ODU cover.

If the seal of the ODU is torn up or the cover of the ODU is removed without permission, the vendor will refuse to provide warranty services.

The seal of the ODU shall not be torn up.

The ODU cover shall not be removed without permission.






Key Points

Do not damage equipment with improper operations.

If the damage is caused by artificial factors, the vendor will refuse to provide warranty services.

Handle ODUs with care.

Hoist and install ODUs with caution to avoid collision with the tower.

If the damage is caused by artificial factors, the vendor will refuse to provide warranty services.

The ODUs damaged during engineering operations must be returned as soon as possible. The vendor shall not provide warranty services after the warranty expires.

It is recommended that the partners complete the station work independently.


Equipment Commissioning – Key Points Methods for commissioning the hybrid microwave are described as

follows:

The AM function of the hybrid microwave should be disabled before the

antennas are aligned.

The antennas should be aligned in low modulation mode provided by

network planning.

The received signal level (RSL) value must be within the scope as

required. The AM function of the hybrid microwave must be enabled after

the antennas are aligned.

Note: During equipment commissioning, perform operations as required. Otherwise, the boards may be damaged and you have to enter the station to replace the damaged boards!

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.

1

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

over DCC

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 – Strategies1. The operations must be strictly compliant with the Acceptance Guide.

2. The acceptance consists of two parts, namely, Acceptance Items and Form

(Recommended) and Acceptance Items and Form (Optional).

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

Acceptance Items and Form (Recommended) 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 the Acceptance Items and Form (Optional).

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 Acceptance Guide to users.

5. The items selected from the Acceptance Items and Form (Optional) 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:


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.

① Disable the AM function.

② Enable 15-minute performance monitoring.

③ Query the performance: No FEC-BER-COR-ER, and only the low modulation mode is available.

④ Enable the AM function.

⑤ 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 be configured synchronously. 2. This method is not the same as the method of decreasing the optical power described in the Commissioning Guide. This is better. The Commissioning Guide will be modified later.

Reclaiming Licenses Strategies and requirements for microwave licenses

Due to the uncertainty of microwave network planning, delivery based on

BTSs 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.


Reclaiming Licenses Hybrid microwave license solution

This will be added in TR6!


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

Notice on Requirements for Entry of Information About RTN Microwave Customer Equipment to CEAS, clearly requiring that engineering information about RTN microwave should be entered to CEAS in a timely manner.

① 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.

② For RTN microwave engineering projects completed in 2008 or earlier, all missing data

should be entered in CEAS in Q1 of 2009.

③ 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.

Overseas Return and Repair Process for Spare Parts of Purchased ODUs Used in Self-Made Microwave Equipment

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 damaged parts and purchased parts as required.


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 parts

to 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).
