Data Configuration Methods

The data configuration function of the BSC6000 includes the

configuration, browsing, storage, backup, and restoration of the

data on BSC6000 and the BTSs under it.

The data configuration is performed on the LMT. The configuration

data can be saved as binary DAT files.

Data Configuration Modes

Offline data configuration

The "offline" mode refers to that the

communication between an LMT and a

GBAM/GOMU is not set up.

User can configure the data in offline

mode, and load the data when later the

LMT is connected to BSC successfully.

So offline mode can be adopted during

initial operation and upgrade of anetwork in a fast and convenient manner.


6/50


Data Configuration Mode

Online data configuration

The "online" mode refers to that the

communication between an LMT and a

GBAM/GOMU is normal, and every step

of the operation takes effect in real time.

After logging in to GBAM/GOMU by LMT

software, user can dynamically adjust

data such as adding, deleting, or

modifying data.

Add Site - Multiplexing Mode

Different multiplexing mode

In 4:1 mode, one E1 supports 15TRX at

the maximum

In 3:1 mode, one E1 supports 14TRX

In 2:1 mode, one E1 supports 12TRX

In 1:1 mode, one E1 support 10TRX.

1:1 and 2:1 mode can support HR.

Parameter DefaultValue

Description

Cell Index 02047 A unique number that identifies the

cell

Cell Name NULL For one cell, the cell name is

defined by LMT user.For several cells, the cell names are

the combination of the defined name

and the suffix number.

Frequency

Band

GSM900 The five frequency bands in the cell

are GSM900, DCS1800,

GSM900&DCS1800, GSM850, and

PCS1900.

PCU Name No PCU Name of the PCU that controls the

cell.No PCU indicates that the cell is not

controlled by PCU.

Number of

Cells

1 Number of cells to be added

Suffix Begin

No.

0 Suffix of the cell name

Configure Device Attributes

Power level: 0~10

When this parameter is set to

0, the transmit power level of

the TRX is the greatest. When

this value is added by 1, the

transmit power is reduced by 2

dB.

Data Reconfiguration

Data Reconfiguration means after initial data configuration,

we can modify or add or delete existing data.

You may reconfigure the data of BSC system for following

reasons: Network optimization

System capacity expansion

Perform data reconfiguration by online mode.
