Figure 1.2 Set Device Property

As shown in Figure 1.2, [Device Type] is set as "Single Module Device" by default. If

"Use SM Board Multiplex Mode" is selected, A interface trunk resources can be

saved.

It is recommended that single module devices should not be adopted. Therefore,

"Multi-module Device" is taken as an example in the following data configuration

procedures.

Note:

"Single Module Device" denotes single-module BSC. "Multi-module Device" denotes multi-module BSC.

After [Device Type] is set as "Multi-Module Device", [Module Number] should be set

according to each actual on-site device configuration. For example, in case of full

configuration, this parameter should be set to "8", as shown in Figure 1.3.

2.4 Configure BM Data

2.4.1 Overview

Because the application of single module BSC is comparatively limited, here, only the

BM data configuration of multi-module BSC is introduced.

BM comprises main control frame, BIE frame and TCSM frame. 1 BM can be

configured with 1 main control frame, 1 BIE frame and 12 TCSM frames. The full

configuration of BM is shown in Figure 1.1.

2.4.2 Main Control Frame

The main control frame is located in Frame1 and Frame2 of BM. The full configuration

is shown in Figure 1.1.

Figure 1.1 Full configuration of the main control frame

I. GMPU

GMPU is the main processing unit of BM. Each BM is configured with 2 GMPUs,

which are respectively configured in Slot10 of Frame1 and Frame2 of the main control

frame. The two GMPUs work in active/standby mode. The active GMPU refers to the

one which is under the control of GEMA. The GMPU in Frame2 serves as an active

board by default. If switchover takes place, the previous standby GMPU will serve as

the active board.

12


13/26


II. GEMA

GEMA controls the active/standby working mode and switchover of GMPU. Each BM

is fixedly configured with 1 GEMA.

III. GNOD

GNOD is used to provide mailbox communication between BIE and GMPU. Each

GNOD can provide 4 master nodes, support 4 BIE groups (Each BIE group requires 1

master node). In the case of full configuration, each BM contains 9 BIE groups, and

requires 3 GNODs. Generally, the default settings can be adopted.

IV. GMEM

GMEM is a cell broadcast interface board, and provides cell broadcast function. Each

BM is configured with 2 GMEMs by default, which work in active/standby mode. The

one in Frame2 serves as the active board, and the one in Frame1 serves as a

standby board. However, the standby GMEM is currently not supported. Generally,

the GMEM is only configured to Frame2. To delete the GMEM in Frame1, please right

click the GMEM and select [Delete Board]. Double click a GMEM to pop up the [Set

GMEM Board Property] interface, as shown in Figure 1.1.

14/26


V. LPN7

LPN7 is used to process SS7. Each LPN7 provides 4 SS7 links. The links provided by

No. 1 LPN7 (in Slot17) are numbered 47. The links provided by No. 2 LPN7 (in

Slot18) are numbered 811.

VI. GLAP

GLAP provides the LAPD links which connect BM and BTS. Each GLAP provides 32

LAPD links. Numbering of the LAPD links provided by each board complies with the

following rule.

Board No. 32 + (031)

For example, the LAPD links provided by GLAP 3 are numbered as 96127.

Each BM can provide up to 192 LAPD links, and can support 64 BTSs and 128 TRXs.

Double click GLAP to pop up the [Set GLAP Board Property] interface as shown in

Figure 1.1.

17


18/26


Figure 1.3 Set BIE Board Property

As shown in Figure 1.3, the basic information of BIE 1 is as follows. Each BIE group

occupies 1 master node. The master node No. is "0". The slave node number is "1",

i.e., the board number. [First HW] is configured as "0". [HW Number] is configured as

"8", i.e., the board occupies HWs 07.

There are total 64 HWs (No.0 No.47, No.76 No.91) allocated to a BIE group.

Generally, groups 06 each occupy 8 HWs, and groups 78 each occupy 4 HWs.

Note: If 4 HWs are merely configured, for an ordinary BIE in the corresponding trunk mode, the number of

available ports is reduced by half. For example, if the trunk mode is "4E1 Port*6TRX/Port", Port0 and

Port1 are available, while port 2 and port 3 are unavailable.

For a transparent transmission BIE, only ports 03 are available.

[Invisible]: It can be selected if there are empty slots (with no BIE plugged in).

18


19/26


[Port Self-Healing]: If selected, it indicates that the self-healing function provided by

the system is enabled.

[Board BIE Position Information]: It indicates the physical position of the BIE in the

system.

[BIE Active/Standby Property]: It indicates whether the BIE is an active or standby

board.

Select the [Basic Information] tab page in the [Set BIE Board Property] tab page in

Figure 1.2.

Figure 1.4 Basic Information

Compared with Figure 1.3, there are 2 additional parameters, [CRC4 Check [000000]]

and [Transparent Transmission of SS7 Signaling] in the [Basic Information] tab page

of the active BIE.

[CRC4 Verification [000000]] is used to configure whether CRC4 is to be performed

for the ports on BIE. The six 0s respectively correspond to 6 E1 ports. If an E1 port is

selected, the corresponding bit will be changed into 1, indicating that CRC4 will be

performed for this port.

19


20/26


[Transparent Transmission of SS7 Signaling] indicates whether BIE is to transparently

transmit SS7 signaling. If it is selected, the [BIE Port Networking Property] tab page

will disappear. BIE Group9 (in Slot23) is configured as a transparent-transmission BIE

by default.

2.4.4 TCSM Frame

TCSM implements the functions of transcoding/data rate adaptation (implemented by

FTC) and submultiplexing (implemented by MSM). In the case of full configuration,

there are 2 TCSM frames in a BM, containing total 8 TCSMs. Each TCSM comprises

1 MSM and 4 FTCs. The full configuration of TCSM frame is shown in Figure 1.1.

Figure 1.1 Full configuration of TCSM frame

Note:In actual application, the hardware of TCSM frame is placed independently on the TCSM rack, instead of

in Frame4 and Frame5 of the BM rack. If BSC is far from MSC, the TCSM rack and MSC are usually

placed together to save transport resources.

2.4.5 Current Rack

Select different racks of BM

For the multi-module BSC, the parameter [Current Rack] is not invalid. For the single

module BSC, Rack1 of BM is configured with TCSM frames.

2.5 Hardware Data Configuration Instance
