OPERATING PRINCIPLES

Simulated Land Line Mode

The simulated land line provides the alarm control panel (with dialer interface) with a backup line

in the event of PSTN line trouble. If the voltage on the land line terminals (

TIP/RNGTIP/RNG

TIP/RNG) drops below

4V for a period of between 10 to 45 seconds (depending on the device connected to the

T1/R1T1/R1

T1/R1

terminals), the GS3060 will switch the connected telephone device to the GSM Network for

approximately 30 to 40 seconds. At the end of this interval, it will check the land line:

•

if the land line has been r if the land line has been r

ed, it will switch the connected device back to the land line;

•

if the land line is still downif the land line is still down

if the land line is still down, it will continue to simulate the land line until it is restored. The

GS3060 will not switch during ongoing calls

NOTE: When the land line is down, the GS3060 will provide a dial tone to any device connected

to T1 and R1, including any telephones on the premises. However, the premise phones will not

be able to dial out over the GS3060.

PTM (Panel Transmission Monitoring)

The GS3060 can also monitor the panel’s attempt to communicate with the central station. If it

determines the panel is having difficulty it will switch the line to the GSM network. This feature is

only active when the GS3060 is configured as a backup communicator. This feature is in addition to

the regular line voltage detection.

The GS3060 will monitor the phone line for four consecutive failed attempts within a 12-minute

window. A failed attempt is considered when line seizure occurs with dialing (alarm panel or customer

telephone), but no 1400Hz tone (or Contact Kiss-off) is detected from the receiver.

Once this condition is met the GS3060 will connect the panel to the GSM network to communicate

the events. Once the GS3060 switches the line it will stay in this mode until the panel hangs up. On

the next event the GS3060 will restart the error detection sequence before switching.

The GS3060 will perform this sequence on any phone number that is detected on the line. Specific

central station phone numbers can be programmed into the GS3060 if desired. Up to four, 20-digit

numbers can be added to your installer profile at Connect 24. If programmed, the GS3060 will only

look for Contact ID kiss-off after these numbers are dialed. A TLM trouble (PGM output activation

and/or reporting code if applicable) will also be activated and/or transmitted when the PTM is

activated. The restoral will be sent at the end of the call.

GPRS Sequence

• When alarm is triggered, the Control Panel goes off-hook

• The GS3060 will assert dial tone

• Control Panel dials the number of the central station. Ensure the alarm panel inserts a minimum 1-

second pause, or has dial tone search enabled before dialing the number

• The GS3060 detects the DTMF dialing and stops dial tone

NOTE: The GS3060 is unable to decode pulse dialing.

• The GS3060 will send the required Contact ID dual tone handshake to the panel

• After receiving the handshake, panel transmits alarm message in Contact ID format

• The GS3060 decodes and transforms Contact ID digits into the IP packet and sends it to the Central

Station Receiver over the GPRS network

• The receiver acknowledges the alarm and sends command to the GS3060 to generate the

corresponding 1400Hz kiss-off signal for 800ms minimum

• After the GS3060 generates kiss-off, the panel goes on-hook if no more alarms need to be sent,

or it can send the next alarm
