Intrastate Long Distance Voice Services
Section I.4: Intrastate Switched Digital Services
Switched Digital Services are not available to Feature Option A Customers.
Domestic Switched Data 56 and 64 kbps services may be accessed using either: T‑1 Digital Access Primary Rate Interface (PRI); PRI provided by a Local Exchange Carrier (LEC); LEC-provided Basic Rate Interface (BRI) access; Digital Data Service (DDS) local loops; or, LEC‑provided Switched Digital Access (SDA). SDA access to Switched Data is available in selected locations.
Switched Digital Services at multiples of 64 kbps may be accessed through Company Primary Rate Interface (PRI) access lines, or LEC‑provided PRI. The Customer is responsible for obtaining the LEC‑provided PRI access line which connects the Customer's premises to the LEC's central office. The Customer is billed directly by the LEC for this access type. Switched services at multiples of 64 kbps require that T‑1 local access lines be equipped with B8ZS line coding from the LEC.
