The configuration procedure is the same as that described in 7.1.3Configuring

6E1Port*2TRX/Port.

7.2 Configuring Chain Networking Data

Chain networking data configuration supports single chain and multi-chain

networking. The single chain networking means that a site is connected to BSC or the

upper-level site via one E1 port. The multi-chain networking means that a site is

connected to BSC or the upper-level site via multiple E1 ports.

The chain networking comprises 5 trunk modes.

7.5 Adjusting TS Manually

I. Overview

Generally, BIE port description and the allocation of OML, RSL and speech timeslots

of Abis interface are automatically completed in BSC Data Auto Configuration System

and no manual adjustment is required.

When different types of BTSs, e.g. BTS22C and BTS30, are configured on the same

chain, it is need to adjust manually timeslots.

II. Operation Procedure

If timeslots need to be manually adjusted, the fill-up of timeslot data should beperformed as per the timeslot allocation in each networking mode described in the

appendix. The specific procedure is as follows.

1) Configure the basic data in the non-manual adjustment mode.

2) Click on the toolbar of BSC Data Auto Configuration System and

refresh DBFs in BAM, as shown in Figure 2.1.

7.6 Configuring Site Monitor Timeslot

I. Overview

The algorithm of monitor timeslot is so complex that it is hard to realize manual

modification. Besides, the user must be well familiar with the equipment when

configuring the monitor timeslots during adding/deleting TRX/Site/Cell.

With the auto calculation function provided by the system, the calculation of monitor

timeslot can be realized automatically, and the corresponding configuration will also

be simplified.

II. Operating Principle

The realization of semi-permanent connection can be divided into three parts

theoretically: from Abis interface to BSC 64K link, BNET network board switching and

from BSC to A interface 64K link.

The both ends of the semi-permanent connection are the most important. One is the

information input for the connection between monitor timeslot device and a site, and

the other is the corresponding end channel No.

25


26/36



After all the above information has been input, the system can decide the

arrangement of the monitor timeslot in various sites, and then perform network board

connection to create a 64K link from Abis interface to A interface, as shown in Figure

1.1.

Figure 1.1 Monitor Timeslot

As shown in Figure 1.1, the monitor timeslot is connected to Site 1 directly, and the

following three messages must be input.

1) Site 1 BIE port No. connecting to monitor device (that is, which port of Site1 is

connected with E4.

2) Abis timeslot No. connecting to monitor device

3) End Channel No. in Semi-permanent Connection Table.

After the corresponding information is input, the system performs calculation

automatically, and decides the arrangement of the monitor timeslot in E1, E2 and E3,

and then works out the HW timeslot No. (End Channel No. in Semi-permanent

Connection Table) corresponding to this monitor timeslot. Finally, it refreshes all

tables relative to the monitor timeslot.

III. Operating Steps

1) In the navigation tree, select a site to be configured with monitor timeslot, and then

right click to select [Configure Site Monitor Timeslot], as shown in Figure 1.1

26


27/36



Figure 1.1 Configure Site Monitor Timeslot Menu

2) Following the above, the [Configure Site Monitor Timeslot] interface pops up, as


Figure 1.2 Configure Site Monitor Timeslot

27


28/36



Refer to Figure 1.2 for the meanings of End Channel No., Site BIE Port No.

Connects Monitor Device and Abis Timeslot No. Connects Monitor Device in

Figure 1.2.

For Site BIE Port No. Connects Monitor Device and Abis Timeslot No. Connects

Monitor Device, the user can select the corresponding information from the pull-down

list directly. While for End Channel No., it can be input by the user manually, or

worked out automatically by the system as per the information input.

Double click the column where the End Channel No. is to pop up the [Set End

Channel No.] interface, as shown in Figure 1.3.

Figure 1.3 Configure End Channel No.

In Figure 1.3, if [User input] is not selected, the End Channel No. will be worked out

by the system automatically as per the information input.

For example, if the transparent transmission BIE HW start No. is 88, the

corresponding End Channel No. = 88 (transparent transmission BIE start No.) x 32 +

2 (BIE port No.) x 32 + 0 (BIE timeslot No.) = 2880.

Then click to finish setting End Channel No.

Then the interface backs to the [Configure Site Monitor Timeslot] interface, as shown

in Figure 1.2.

In Figure 1.3, if [User input] is selected, the End Channel No. must be input

manually. In this case, the End Channel No. box is enabled. Meanwhile, the other

three parameters including End Equipment Type, BIE Port No. and BIE Timeslot

No. are dimmed, as shown in Figure 1.4.

28


29/36



Figure 1.4 Configure End Channel No.(User Input)

In Figure 1.4, the user must input End Channel No. manually before click to

return to the interface shown in Figure 1.2.

3) Click in the interface shown in Figure 1.2 to configure more monitor timeslot

for the site, or click to remove the unnecessary monitor timeslot. Then click

to finish the configuration for the site.

4) After all data has been configured, click to refresh all DBF tables.

Caution:

When using auto calculation function to configure monitor timeslot for a site, make sure not to select

Manual Mode when selecting BSC BIE port.

After new monitor timeslot are generated by auto calculation function, the previous monitor timeslot

configured manually are still effective. Besides, the user can still set Semi-permanent Connection"

and BSC BIE Semi-permanent Connection manually, and set the BIE port of the BSC where the site

is as Manual Mode.

5) After the transfer operation is successfully implemented, the user can click button in the [Local Office] tab page to view the Semi-

permanent Connection record generated automatically, as shown in Figure 1.5.
