With the announcement of the end of the Public Switched Telephone Network (PSTN) by the telecom operator community, the IP@larm converter was designed to extend the life of the existing PSTN transmitter base, in complete security and at low cost.

  • IP@larm constantly monitors the state of the IP connection to the remote monitoring centre, assures an automatic backup connection via a GPRS transmission channel, and enables remote control of all transmitter types.
  • IP@larm is one of the only products on the market capable of transporting an audio stream via VoIP, and to allow alarm verification without a callback.
  • IP@larm can be installed quickly and with complete confidentiality, thanks to a download procedure which allows centralisation of the deployment, operation and management of the installed base.

A PSTN TRANSMITTER MUST NOT BE CONNECTED DIRECTLY TO AN INTERNET “BOX”? WHY IS THAT?

Apart from the risk of unavailability of the internet connection (no battery backup for the “box”, loss of the DSL connection sometimes requiring “cold” reboots), several technical factors are likely to degrade the signals generated by the PSTN transmitters during transport, whether DTMF modulation (voice frequencies) or FSK (modems). These dysfunctions are non deterministic and have a random impact on the logical connection between the PSTN transmitter and the remote monitoring centre.

To address this problem, the IP@larm converter is installed between the PSTN transmitter and the “box” or the customer’s router, locally interprets the signals generated on the analogue interface of the PSTN transmitter, and manages the dialogue with the receiver front end at the remote monitoring centre using an encrypted IP protocol. This guarantees reliable and secure transmission of information over the internet network.

SEVERAL VERSIONS MEETING ALL REQUIREMENTS

The IP@larm range comprises four models. The IP@larm converter is available in the form of electronic cards which can be installed inside a PSTN transmitter, or in a case equipped with a power supply, a slot for a backup battery, mains and low battery charge indicators, and built-in protection against opening and removal.

 

COMPATIBLE WITH ALL TRANSMITTER TYPES

IP@larm emulates the most common PSTN protocols (CESA, CONTACT ID, DAITEM, SERIEE, SIA, SURTEC…). These protocols are configured on the front end receiver and all newly-configured protocols are immediately made available to the whole IP@larm converter installed base. Additionally, the remote control input and output available on the IP@larm converter allow it to interface with any devices not equipped with a PSTN transmitter (power stations, street lighting, automated equipment, etc.).

INCREASED EFFICIENCY THANKS TO AUDIO ALARM VERIFICATION

IP@larm supports the audio mode of the PSTN transmitters. The audio stream is transported on the IP network (VoIP) and can be operated directly by the operators, without them having to make a callback. The audio stream is encrypted for increased security, and an echo cancellation mechanism provides optimal listening comfort.

SIMPLIFIED INSTALLATION AND CONFIGURATION PROCEDURE

Deploy your installed base of IP@larm converters rapidly and in complete security. A profile generated by the remote monitor and communicated to the installer contains all the information needed to connect the transmitter to the operations centre. This profile is programmed into IP@larm and enables the converter to download its configuration automatically from the operations centre when it is brought online. To ensure the security of your information system, an encoding mechanism allows all sensitive information in the profile to be masked out, such as the IP addresses of the front end receivers.

RELIABLE, SAFE AND SECURE CONNECTIONS

Connecting a PSTN transmitter with the help of an IP@larm converter means protecting yourself from the risks associated with unavailability of the connection. IP@larm manages up to four IP routes, constantly  monitors the state of the main IP connection, and if necessary establishes a backup connection using a GPRS or GSM channel. All IP transmissions are encrypted for privacy and to limit the risk of cyber attacks.

CENTRALISED ADMINISTRATION AND MANAGEMENT

The IP@larm converter’s configuration can be remotely viewed and modified, or its software upgraded. IP@alarm also has a log which stores client and system events (dialling, connection reports, configuration modifications, functional anomalies, etc.). All logs can be viewed from the operations centre and automatic reports can be generated to create a statistical compilation of the data.
