Fewer than half of all domestic telephone calls are successful.

For voice telephony, sound quality is often not acceptable for regular conversation.

More than 100 faults are reported per year for each 100 telephone mainlines.

No services beyond limited electronic mail capabilities are supported by the local telecommunications infrastructure.

Large businesses which want access must link their networks directly to infrastructure backbone outside their community.

50-70% of domestic telephone calls are successful.

Dropped connections are frequent and extremely disruptive.

For voice telephony, sound quality is acceptable for regular conversation.

Between 50 and 100 faults are reported per year for each 100 mainlines.

The telecommunications infrastructure in most areas of the community supports dial-up modem transfer speeds of 9.6 Kbps or less. Some areas may support speeds of 14.4Kbps.

Large businesses and ISPs can link their networks to a local infrastructure backbone, but backbone capacity is frequently inadequate to support user demands.

Packet loss is significant and regularly disruptive for any online activities.

70-90% of domestic telephone calls are successful.

Connections are dropped with noticeable frequency and are somewhat disruptive. 

Fewer than 50 faults are reported per year for each 100 mainlines.

Users have access to dial-up modem transfer speeds of up to 28.8 Kbps. 

Leased lines with transfer speeds of up to 64 Kbps are widely available for businesses and ISPs. Limited higher-speed lines are available in some areas.

Backbone facilities serving the community are usually sufficient, although regular peak demand periods result in slower network response times. 

Packet loss by the network may occur but is not generally disruptive.

Over 90% of domestic telephone calls placed are successful.

Fewer than 10 faults are reported per year for each 100 mainlines.
 
There is widespread access to dial-up modem transfer speeds up to 56 Kbps, with some access to high speed solutions such as DSL, cable modems and wireless solutions.

High speed services of 1.5 Mbps are common, with higher speeds available in some areas.

Adequate backbone capacity exists to support community needs without significant transmission delays except during infrequent periods of high demand. 

Packet loss by the network is below 10%.
