3.2 Allocating transmission capacity with Traffic
Manager
The Traffic Manager is a graphical tool that allows you to allocate BTS
transmission capacity independent of which Nokia MetroSite transmission unit is
used. You need only to define the line interface (e.g. Port 1) and the incoming
timeslot allocation on the Abis according to the transmission plan.
With the FXC E1/T1 Symm transmission unit, the cross-connections are created
automatically after the capacity has been set and approved.
If a Site Configuration File is used for transmission capacity allocation, the Abis
TS Allocation table is filled automatically. You only need to check the
correctness of the capacity allocation.
Figure 9. Traffic Manager for allocating BTS transmission capacity
In the case of 1.5 MB links (T1), the Traffic Manager automatically reduces the
number of timeslot rows in the table to 24.
The capacity to be used is defined by selecting its signal type (TCHs, TRXSIG,
OMUSIG, TRXSIG on TCHs or OMUSIG/TRXSIG1) and by reserving required
time slots and bits.
