An 1+ intralata call is received.
Step 1
Determine if 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 4.
Check the carrier table for a carrier access code (CAC). If a CAC is available, the Cisco BTS 10200
Step 3
Softswitch will select the call route and route the call based on the CAC. If a CAC is not available,
proceed to Step 3a.
a.
Check the POP table for a configured IP transfer point (ITP). If an ITP is configured, proceed to Step 4a.

Determine if a LECOSS is defined in the POP table. If a LECOSS is defined in the POP table, the
Cisco BTS 10200 Softswitch will select the call route and 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 specified PIC. If a PIC is specified, proceed to Step 4b. If a PIC is
not specified, the Cisco BTS 10200 Softswitch will route the call to the announcement server and
will check the POP table for a specified PIC. If a PIC is not specified, the Cisco BTS 10200
Softswitch will block the call or if a dial plan is available, the Cisco BTS 10200 Softswitch will
select the call route and route the call according to the dial plan routing information.
Check the intra carrier table for a specified PIC. If a PIC is specified in the intra carrier table, the
Cisco BTS 10200 Softswitch will select the call route and route the call based on the PIC
information. If a PIC is not specified in the intra carrier table, proceed to Step 4c.
Determine if a LECOSS is defined in the POP table. If a LECOSS is defined in the POP table, the
Cisco BTS 10200 Softswitch will select the call route and 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.
