ATA Settings
Use the WebUI to configure the two FXS ports on the ATA. Once an ATA is connected to the Synapse network, the WebUI is
updated to show all ATA-related menus and configuration items within menus. (The ATA must be running a compatible software
version.) If the ATA is deleted (using the WebUI's Modify Device page), all these ATA-related menus and configuration items
disappear. However, the device list continues to show a count of ATAs.
Using the Private Line Automatic Ringdown (PLAR) feature, you can create a private intercom line or a door phone. When you
enable the PLAR feature through the WebUI, an analog device (for example, an analog telephone or door phone) connected to
an ATA FXS port will ring a destination when it goes off hook. The destination can be an Synapse Deskset extension or, if using
Call Appearance mode, a ring group. You can configure this destination on the ATA Settings page of the WebUI.
During a call on the PLAR line, a user can press Deskset dial-pad keys to transmit DTMF tones (touch tones) to the analog device.
The DTMF tones can control a door relay or other function. This feature depends on your analog device; you cannot program an
entry code through the ATA.
