calls to telephones in a specific geographical area called a zone
or band. Typically a flat monthly fee is charged for this
service.

receive calls originating within specified areas without a
charge to the caller. A toll-free number is assigned to allow for
reversed billing.

type and digits received

allows Enbloc dialing by buffering user-dialed digits until
a complete DN has been dialed

provides the ability to map user-dialed digits to a service
type on a Call by Call basis

allows long distance carrier selection via user-dialed
Carrier Access Codes

Consult your customer service representative to determine
how your dialing plan is configured.
