Carrier Based Routing

This section provides a detailed description of the Cisco BTS 10200 Softswitch carrier based routing.
Refer to
detailed step-by-step carrier based routing flow.
Carrier based routing call is received.
Step 1
Determine if the carrier is being screened. If the carrier is being screened, proceed to Step 3. If the carrier
Step 2
is not being screened, proceed to Step 4.
If the carrier is being screened, the Cisco BTS 10200 Softswitch will determine if the carrier call
Step 3
processing is being remotely blocked (RTM_CP_BLOCK). If the carrier call processing is being
remotely blocked, the call can not be completed and will be dropped.
If the carrier is not being screened, the Cisco BTS 10200 Softswitch will determine if the carrier is a
Step 4
recognized service provider. If the carrier is a recognized service provider, proceed to Step 5. If the
carrier is not a recognized service provider, proceed to Step 6.
If the carrier is a recognized service provider, the Cisco BTS 10200 Softswitch will use the service
Step 5
provider routing to select the call route and to route the call.
If the carrier is not a recognized service provider, the Cisco BTS 10200 Softswitch will determine if a
Step 6
carrier dial plan is configured. If a carrier dial plan is configured, proceed to Step 7. If a carrier dial plan,
is not configured proceed to Step 8.
If a carrier dial plan is configured, the Cisco BTS 10200 Softswitch will use the carrier dial plan to select
Step 7
the call route and to route the call.
Step 8 If a carrier dial plan is not configured, the Cisco BTS 10200 Softswitch will determine if a carrier remote
call processing to local exchange carrier operations support system is available
(RTM_CP_CARRIER_2_LECOSS). If the RTM_CP_CARRIER_2_LECOSS is available, proceed to
Step 9. If the RTM_CP_CARRIER_2_LECOSS is not available, proceed to Step 10.
Step 8 is skipped for toll traffic. If the traffic is toll traffic, proceed to Step 10.
Note
If the RTM_CP_CARRIER_2_LECOSS is available and if the traffic is not toll traffic, the Cisco BTS
Step 9
10200 Softswitch will use the RTM_CP_CARRIER_2_LECOSS to select the call route and to route the
call.
If the RTM_CP_CARRIER_2_LECOSS is not available, the Cisco BTS 10200 Softswitch will use the
Step 10
carrier guide index to select the call route and to route the call.
