2.7 ST Connecting Options
Direct PSTN Connection
Advantages and disadvantages
This is the most reliable and simplest connecting option. The costs include acquisition
costs plus a line installation fee, yet the ST operation is relatively cheap (monthly
fee).
Cautions
 The line must be dedicated to ST only, serving no other devices.
 The line may not be serial or group line.
Notes
 You are not recommended to use the telephone set offered for lease while
arranging the line.
 The telephone socket and associated cabling are the network provider’s
property and may not be tampered with.
 Report the ST installation and submit compliance certification upon request.
 Your follow-up cabling must be in conformity with the relevant safety
regulations.
 You are recommended to secure your line against piracy,e. g. use a
telephone lock.
GSM Gateway Connection
Advantages and disadvantages
This is a rather costly solution for places where no telephone line is available.
Cautions
 Back up the GSM gateway reliably in case of power outage.
 With a pre-paid SIM card, ensure credit monitoring and on-time charging.
Tips
 Verify the signal coverage and intensity in the place before selecting your
GSM provider.
