Circuit switched (dialed) service
SwiftBroadband also provides high-quality telephone services (including
secure mode). The following types of circuit switched connection are
available:
• Standard voice. A connection for voice only. The voice signal is
compressed to 4.0 kbps, which reduces the bandwidth use and
consequently the cost. This is also called AMBE2.
