5 DETAILED GUIDE

5.1 How to create a BSC5.1.1 Preconditions

The semi-permanent links that enable the RCF-BSC and RCF-adjacent MSC dialogs must already existin the SSP.

5.1.2 Creating a BSC

To create a BSC at the CSCN:

a) Check that the routing to the BSC is correct:

• for analysis, using commands ANSIN (see FOP ANSIN) and ANSIL (see FOP ANSIL),

• for routing, using commands ASMIN (see FOP ASMIN) and ASMIL (see FOP ASMIL),

• for the circuit groups, using command FSMIN (see FOP FSMIN),

• for the signaling links, using command CSMIN (see FOP CSMIN).

b) Check that the BSC that you want to create does not exist at the RCP, using command INTBSC (seeFOP INTBSC) and follow the instructions in the following table.

If... then...

the BSC does not exist create the BSC, using command CREBSC (see FOP CREBSC).

It is recommended to assign the LAC value to the “a” BSCTYP pa-rameter (see Table 2) to optimize the BSC-LAC congestion manage-ment.

If the BSC is equipped with transcoders that support AMR, use theAMR values (see value k in Table 2). This is only applicable if thecorresponding functional option is activated.

If the BSC is already created a) check the BSC characteristics (CPD, BSC name and number),using command INTBSC (see FOP INTBSC),

b) if necessary, modify the BSC characteristics, using commandMODBSC (see FOP MODBSC).

For a list of the parameters to use in the CREBSC, INTBSC and MODBSC commands, see AppendixA.
