0+ interlata calls. Refer to
reviewing the following detailed step-by-step 0+ interlata call routing flow.
A 0+ interlata call is received.
Step 1
Determine if a 101XXXX number has been dialed. If a 101XXXX number has been dialed proceed to
Step 2
Step 3. If a 101XXXX number has not been dialed proceed to Step 5.
Check the carrier table for a CAC. If a CAC is available, the Cisco BTS 10200 Softswitch will select the
Step 3
call route and route the call based on the CAC. If a CAC is not available, proceed to Step 4.
Step 4 Check the POP table for a defined LECOSS. If a LECOSS is defined in the POP table, the Cisco BTS
10200 Softswitch will route the call via the LECOSS. If a LECOSS is not defined in the POP table, the
Cisco BTS 10200 Softswitch will block the call.
Check the subscriber table for a defined PIC. If a PIC is defined in the subscriber table, proceed to Step 6.
Step 5
If a PIC is not defined in the subscriber table, proceed to Step 7.
Check the subscriber profile for ea-use-pic entry. If the subscriber profile contains an ea-use-pic entry,
Step 6
the Cisco BTS 10200 Softswitch will select the call route and route the call based on the PIC
information. If the subscriber profile does not contained an ea-use-pic entry, return to Step 4.
Check the POP table for a block-eawopic entry. If the POP table contains a block-eawopic entry, the
Step 7
Cisco BTS 10200 Softswitch will block the call. If the POP table does not contain a block-eawopic entry,
