Chapter 1: Introduction
Circuit-Switched (dialed) service
The following types of circuit-switched connection are available:
• Standard Voice. A low-tariff connection for voice only. The voice signal is
compressed to 4.0 kbps, which reduces the bandwidth use and
consequently the tariff.
• 3.1 kHz Audio. A high quality connection which can be used for Premium
Voice or G3 fax. The signal is uncompressed 3.1 kHz audio, which allows for
optimum voice quality.
• ISDN. A high quality connection which can be used for voice (3.1 kHz
Audio), G4 fax or 64 kbps UDI/RDI data.
