VoiceLink

Voicelink is an analogue PSTN to digital converter for devices which use PSTN modems to make voice/data calls. Using the onboard telephone line output, VoiceLink is compatible with a wide range of telephone set connections or autodialled PABX Analogue line connections. VoiceLink is generally designed to be installed as a plug & play device, however, any configuration changes can be made via a web application or a telephone handset.

VoiceLink uses a radio path with a roaming SIM which connects to the best available network to send voice calls, system notifications & trouble indicators via the mobile network. VoiceLink prioritises calls over the 4G/VoLTE network but will fall back to 2/3G where VoLTE is unavailable, offering the best possible resilience.

It’s as Easy as 1, 2, 3!

1. Wire and connect power – Refer to the installation section for information on the steps.
2. Wait for the red LED to flash to indicate it is connected to the mobile network.
3. When the green LED flashes to indicate the signal strength level of the device, providing it is acceptable (refer to the LED section for details), you’re ready to make & receive calls! For customisation, please use the CSL Voicelink web application.

A CSL Signal Analyser is used to determine if enough base stations (2 or more) are available at the site and if they can supply sufficient signal strength (30% and above). This will determine the optimum location for the VoiceLink’s aerial to be mounted.

If you do not have a Signal Analyser we recommend powering up the VoiceLink, connecting the aerial and checking the signal strength LED to decide where to fit the aerial. See Connectivity LED section for more information on interpreting the LEDs.

IMPORTANT PREREQUISITES

• All third-party end devices must be updated to the latest software version to ensure compatibility.
• To ensure seamless integration with access control systems (RCO, APTUS, etc.), please program the door open command to an asterisk (*) only.

Before power is applied:

1) Open the product casing from the top using a screwdriver to prise it open
2) Ensure SIM is fitted (this should be pre-installed by CSL already)
3) Attach the antenna by twisting to fit
4) Connect the PSTN modem output of your device to VoiceLink’s telephone line input
5) If an output is required, connect accordingly

You can then connect the device to a power supply, plug the back-up battery in and close the lid.

Voicelink has several ports, as shown in the diagram above. Whilst the power, & telephone lines are mandatory, the Relay Output wiring is optional & can be used to notify external power failure and/or mobile network loss. Please follow the below diagrams for assistance in getting your unit up and running

Trigger the auto dialler of your control equipment, watch the white LED turn on to show that the line has been picked up and it will dial the number programmed into the control equipment.

Although not normally required, in some cases, you may need to insert the international phone number into your control equipment and remove the first 0 (ie +44 1234 567890, +353 1 234 5678, +31 612 345 678, etc) before voice calls can be sent.

You should not need to programme VoiceLink from the default settings. If you require bespoke settings, you are able to do this via the VoiceLink Web Application (see QR code/URL at start of guide). The VoiceLink Web Application will allow you to view trouble alerts create additional user accounts and check the live device status such as the current battery/mains power state, whether the device is online or the telephone line has been picked up. It will also allow you to customise the device programming with options to override the outgoing telephone number, change the low battery checking alert level and the periodic test frequency.

To register VoiceLink to the Web Application follow these steps

1) From the home page, enter the Lift section

2) Select + New Lift from the menu

3) Add a name and description of your choosing

4) Change the Device ID Type to IMEI and enter the IMEI number (can be found on a sticker on the side of the device or on the radio module) under Device ID

5) Add the site location

6) Change the Device type to 4G.VoLTE

7) Set a device and programming password (default is 000000 and 0)

8) Click on Create

Your device will now appear in the list to which you can connect to using the Remote Configuration button
