SCCP:Configuration of layer

General guidelines for configuration of SCCP for proper operation include the following steps:

1. The SCCP general allocation (see Note below) (TB640_MSG_ID_SS7_SCCP_OP_ALLOC) must precede all other messages (other configuration SCCP alloc, get, states and stats). The response of this message is a SCCP handle.
2. The SCCP network allocation must be made (with the SCCP handle from step 1) for a particular network identifier with a particular variant, self point code and subservice field type. The response of this message is a SCCP Network handle.
3. The SCCP LSAP allocation must be made (with the SCCP handle from step 1, network handle from step 2 and the unique identifier of the MTP3 userpart) to connect with the MTP3 userpart
4. The SCCP route allocation must be made (with the SCCP handle from step 1 and the lsap handle from step 3 for a particular variant, replicated mode and DPC
5. The SCCP userpart allocation must be made (with the SCCP handle from step 1 and the network handle from step 2 for a particular subsystem number
6. The SCCP GTT association allocation must be made (with the SCCP handle from step 1) for a particular global title association
7. The SCCP GTT address map allocation must be made (with the SCCP handle from step 1 and the Gtt asso handle from step 6) for a particular global title address map

Configuration notes

• Step 2 can be done for 1 to the maximum number of configured Networks
• Step 3 can be done for 1 to the maximum number of configured LSAPs
• Step 4 can be done for 1 to the maximum number of configured Routes
• Step 5 must be done for 1 to the maximum number of configured Userparts
• Step 6 must be done for 1 to the maximum number of configured GTT Asso
• Step 7 must be done for 1 to the maximum number of configured GTT Addrmap
