WEB LMT INTRODUCTION

• The LMT provides graphical user interface (GUI) for you to operate and maintain the BSC6900 on the Web page.

• The alarm management, trace management, performance monitoring, and device maintenance can be performed through menu operations

• The MML commands can be run for data configuration and O&M on the LMT

USER TYPES

Page19

• Local user – Being created and authorized by MBSC LMT

– The internal operator is admin, and the default password is 11111111

– The external operators are divided into five levels. Each level has different authorities

• EMS user – Being created, managed and authorized by

M2000

– The authorized EMS users can also log in to the

M2000 server through the M2000 client for

BSC6900 operations.

COMMAND GROUP

Page20

• The BSC6900 system uses 32 command groups (G_0 to G_31) to manage commands. Different command groups can be assigned to different operators, so that they will have different operation authorities.

– Groups G_0 to G_14 are predefined by the system, the contents cannot be changed

– Groups G_15 to G_31 are initially null, the contents can be defined.

BSC INTERFACE PROCESSING SUBSYSTEM

Page49

• The BSC interface processing subsystem consists of the following logical units:

LOOPBACK MODE

Page50

Timeslot Loopback

Loopback Mode

Port Loopback

Remote speech

channel loopback DSP speech

channel loopback


BSC6900 26

TIMESLOT LOOPBACK

Page51

• You can set the loopback direction by selecting a loopback mode. By doing this, you can analyze whether the fault is on the system side or on the transmission lines or whether it is a transmission problem or software problem.

– Remote loopback

– Local loopback

PORT LOOPBACK

Page52

• Port loopback is used to loop back the data received or transmitted by the port in the specified direction. You can perform the port loopback to locate a fault of a link disconnection, and link intermittence problem.

STEPS IN REPLACING A BOARD

Page90

Steps: There are two steps in replacing a BSC6900 board:

unfasten the faulty board and insert the new board.

Prerequisites: The tools required for unfastening the board are

available, including ESD wrist strap, Phillips screwdriver, ESD box

or ESD bag, dustfree cloth, and fiber cleaner.

Background information: All the boards except the OMUa support

hot swap.

Precautions: To avoid electrostatic damage, wear ESD wrist strap

correctly before replacing a board. If an ESD wrist strap is not

available or cannot be properly grounded, please wear ESD

gloves.

INSERTING THE NEW BOARD

Page92

Insert the new BSC6900 board to the subrack.


BSC6900 47

REPLACING A SPARE BOARD

Page93

Principles of replacing a board Replacing an active or standby board: To replace an active board, run SWP BRD to switch over the boards, pull out the now-standby board, and insert the new board. To replace a standby board, pull out the standby board and insert the new board. Replacing an independent board: This operation impacts the services and can cause service interruption. To replace an independent board, transfer the services of the board, run INH BRD to inhibit the board, pull out the faulty board, and insert the new board. Replacing a faulty board: If the faulty board is the DPU and only one or several DSPs are faulty, inhibit the normal DSPs, and replace the faulty board with a new one. Verifying the board replacement: Run LST BRD to query the board inhibition status. If the board is in "Inhibited" status, run UIN BRD to uninhibit the board and observe whether the board works normally. If not, check for alarms and analyze the problem according to the alarm.


Page94

Replacing an XPU

Precautions: Replacing an active or standby XPU does not affect the

services; replacing an independent XPU causes interruption of all the

services over the BSC6900.

Operations: To replace an XPU, run DSP BRD to view the board status. If

the board works normally, transfer the services of the board, run INH BRD to

inhibit the board, pull out the board, and insert the new board. If the board is

faulty, pull out the faulty board and insert the new board.

Verifying the board replacement: Run LST BRD to query the board

inhibition status. If the board is in "Inhibited" status, run UIN BRD to uninhibit

the board. If the board is in "Uninhibited" status, run DSP BRD to view the

board status and check for alarms. If an alarm is generated for the board,

analyze the problem according to the alarm.


BSC6900 48


Page95

Replacing a DPU

Precautions: Replacing a DPU causes interruption of the services over the

DPU.

Operations: To replace a DPU, run DSP BRD to view the board status. If

the board works normally, transfer the services of the board, run INH BRD to

inhibit the board, pull out the board, and insert the new board. If the board is

faulty and one or several DSPs are faulty, run INH BRD to inhibit the normal

DSPs, pull out the faulty board, and insert the new board.

Verifying the board replacement: Run LST BRD to query the board

inhibition status. If the board is in "Inhibited" status, run UIN BRD to uninhibit

the board. If the board is in "Uninhibited" status, run DSP BRD to view the

board status and check for alarms. If an alarm is generated for the board,

analyze the problem according to the alarm.
