ARS Routing: Calls to Area Code of Non-Local System or to Area Codes Near Non-Local System (Absorb = 0)

For primary routes serving calls to area codes 410, 703, and 512, the FRLs are set to low values.

The FRL is higher for primary routes to areas near but not in the same area code as one of the other private network systems. For instance, a 703 area code route via a tandem PRI pool has an FRL of 1.

Secondary routes using the PSTN have FRLs as high as 6.

For primary routes serving calls to area codes 410, 703, and 509, the FRLs are set to low values.

The FRL is higher for primary routes to areas near but not in the same area code as one of the other private network systems. For instance, a 301 area code (Maryland) route via the tandem tie pool has an FRL of 2.

Secondary routes using the PSTN have FRLs as high as 6.
