Active Communications
The Active Communications for an account can be viewed in the Status Window while the account is open.
Connection Methods
You may connect to a DSC panel using the DLS IV software in a variety of different ways. These include PC-Link, T-Link, and PSTN.
PC-Link
PC-Link is a method of connecting to a DSC panel by connecting a serial port on your computer directly to the security panel.
T-Link
PSTN
PSTN stands for Public Switched Telephone Network. This method is the most common. In order to connect to a DSC panel over the telephone line, you will need an MD-12 modem connected to a free serial port on your computer, a free phone line for the modem, and the telephone number that the security panel is connected to on site.

Cancel Communications
The "Cancel Communications" function is available in the Account Toolbar. This function may be used to cancel a current (or pending) communication job, but this function should not be considered a "Hangup immediately" command.
When pressed, the communication manager will stop sending upload or download commands to the panel when it is determined to be “SAFE TO STOP". This means that the communication session that you are trying to cancel will NOT hangup with the panel immediately, but will wait until the communication can be ended gracefully, leaving the panel in an operational state.
Global Upload
If a global upload was cancelled, data that was uploaded from the panel will be saved, and any options that were not yet uploaded will remain tagged for upload. This allows an opportunity to restart the communication at a later time.
Global Download
If a global download was cancelled, any options that were not downloaded will be saved to the database and tagged for download. The remaining options may be downloaded at a later time.
Tagged Communication
If a tagged communication was cancelled, tags for options that were completed successfully will be cleared, tags for options that were not completed will be saved, and may be restarted at a later time. Data that was uploaded successfully will be saved to the database.
