AVAILABLE LINE TYPES
Primary Line
A primary line is just that — a fully featured, main number line that identifies you with Access. Use your current local phone number, or get a new number. As long as it's local to your area, you're good to go.
Secondary Line
It's secondary, but it's still a fully featured line. This line allows another separate phone number under your primary account. You can use either an existing number or get a new number. Use your secondary line as a business line, or perhaps for a teenager in your home (yak yak yak).
Fax/Modem/Alarm (FMA) Line
A FMA line is a special type of secondary line intended for use with Fax, Modem, and Alarm-type applications. The FMA line supports standard voice calls. However, this line is considered 'un-featured'—it cannot support active features such as Call Waiting.
