Note

Allocate transmission capacity as follows:

1. Select the line interface used (Port 1 - Port 16, depending on the

transmission unit).

2. Click the appropriate traffic or signal button.

3. Click in a cell in the Abis timeslot allocation table.

4. Select an option, e.g. link speed, as required by the SW. (The selections are

different depending on the signal type.) The SW then automatically

reserves the time slots and bits to be used for the selected function.

5. Repeat steps 2 - 4 until all types of necessary BTS signals are marked.

If you want to modify the allocation table at this point, you have to first delete

prior allocations. Click the right mouse button on the cells to be modified and

delete either one signal allocation, all signal allocations of a particular type or

delete all allocations for the selected port.

6. Check that the signal timing (either ‘Normal’ or ‘Satellite’) is correctly set.

7. Click the OK button to send the information to the BTS.

If you want to modify the allocations after you click OK in the Traffic Manager,

you have to first run Undo Commissiong and reset the BCF.

When the link capacity restricts normal signal allocation, you can use the

‘TRXSIG on TCHS’ and combined ‘OMUSIG/ TRXSIG1’ signal types.

The signal types are discussed below in more detail:

OMUSIG

The BTS can have one OMUSIG which allocates 2, 4 or 8 bits in one time slot

depending on the link speed used (16 - 64 kbit/s). If a combined OMU/TRXSIG1

is used, the allocation of the OMUSIG is disabled.
