Using CLI displays
Devices that display the incoming number (telephones with display, external displays, etc.) can be directly connected to the FCT line interface in the same way as an ordinary telephone. If your subscription includes the Calling Line Identification (CLI) service and the caller´s network sends the number, the FCT will send the caller´s number towards your CLI display.
In general, your FCT will be programmed (according to your country specifications) to send the CLI information with the right standard so that your CLI device works properly.
Refer to your CLI telephone or display user guide for further explanations on your CLI indications.
Tip: if you run the Ring Back Test on page 14
(lift the telephone, dial **#10# and hang up), you can check if the following number “1234567890” appears on your CLI display. If it does not, the FCT is not using the right standard.
If you experience that your CLI device is not showing the calling numbers, you may need to change the FCT settings.
This is done by dialing one of the following sequences, depending on the CLI standard that your CLI device supports (check its user guide).
CLI standard | Dialing sequence |
ETSI DTMF | **0002*1# |
|
|
ETSI V.23 | **0002*2# |
|
|
Bellcore | **0002*3# |
Tip: if you cannot figure out which CLI standard to use, try all three sequences, following each of them by a Ring Back Test. The CLI standard whose Ring Back Test prints a “1234567890” on your display will be the correct one.
In order to disable the CLI Display functionality and therefore stop viewing calling numbers, dial **0002*0# from a DTMF (Pulses) telephone connected to the FCT.
Tip: if you do not want your telephone number to appear at the caller’s location, you can dial #31# before the phone number you are going to call
