Chapter 3 Dial Plans and Routing

Circuit Code

The Circuit Code (circuit-code) table defines the circuit code value for the transit network selection
(TNS) parameter. The circuit code value is defined based on the line, class of service, and call type.
Special circuit code values are assigned to calls from coin or hotel motel lines. If special circuit code
values are not required, the default circuit code values are based on the call type sent.

Service Provider

The Service Provider (service-provider) table is used when there are multiple service providers
providing service via a single logical Call Agent.

Carrier Based Routing

Carrier based routing enables the routing of Cisco BTS 10200 Softswitch calls based on carrier. Carrier
based routing provides multiple service provider support. Additionally, carrier based routing enables
matching of the carrier ID and the trunk group to individual service providers. Individual dial plans can
be configured for each service provider or default routing can be enabled.
