6 Voice Services (W35 only)
The Ericsson W35 provides circuit switched voice services via the
telephony line interface with high speech quality.
6.1 National Profiles
Country specific settings for the telephony services can be configured. This
can be achieved by setting an overall profile either automatically by loading
a profile (based on the SIM card’s MCC) when the Ericsson W35 is
rebooted or manually by configuring a specific profile.
These settings include parameters for the POTS interface (i.e. impedance,
ringing signals, cadence, levels etc), CLIP service configuration, and
settings for supplementary services.
National profiles for the following countries are currently supported:
• Austria (AT)
• Australia (AU)
• Spain (ES)
• Hungary (HU)
• New Zealand (NZ)
• Sweden (SE)
• United Kingdom (UK)
• United States (US).
If none of the above methods are used for setting an overall national profile,
the following features have their own profiles (for the above described
countries) that can be enabled/disabled individually.
Country specific settings for supplementary services are only included in
the above described national profile.
6.1.1 Tones and Signals Profile
The tones and signals profile includes local settings for ringing signals and
information tones generated by the Ericsson W35 (in opposite to the tones
received from the network).
These settings might be overridden by the operator network.
6.1.2 Voice Codec
The Ericsson W25 supports the following voice codecs in all profiles:
• All GSM vocoders
• Enhanced Full Rate /EFR), Full Rate (FR), Half Rate (HR)
• WCDMA Adaptive Multirate (AMR) encoders.
