POTS Controller

The POTS Controller component controls the features of the Q-SYS interface with a Plain Old Telephone Service (POTS).

If you are connecting to an analog phone system, you can connect from the wall RJ-11 jack directly to Q-SYS hardware supporting a POTS connection:

If you are connecting to a digital system, you can use an FXO Gateway that has an analog POTS connection and a network connection.

Core Properties

Name

The Name may contain ASCII letters 'a' through 'z' (case-insensitive), the digits '0' through '9', and the hyphen. Names cannot begin or end with a hyphen. No other symbols, punctuation characters, or blank spaces are permitted.

Note: This name must match the Hostname for the Core as defined in Core Manager. If you use Telnet or third-party external control, you must enter the Name exactly as it is entered here.

Location

User-defined name that groups the component with other components in the same physical location – for example, "Rack 1" – or in the same organizational scheme.

Model

Select your Q-SYS Core processor model. See POTS Controller for a list of selectable Core models.

Is Redundant

If you have redundant Cores in the installation, select Yes, otherwise, leave it as No.

Note: The NV-32-H (Core Capable) does not support Core Redundancy.

GPIO

(Core 110 Series models only)

This property determines whether to expose GPIO In and GPIO Out components in the Inventory tree.

  • Disabled: GPIO components are not shown in the Inventory tree. Use this setting for Core 110v2, which does not include GPIO inputs and outputs.
  • Enabled: (default) GPIO components are shown in the Inventory tree. Use this setting for Core 110f v1 or Core 110c, as these models include GPIO inputs and outputs.
  • Optional: GPIO components are shown in the Inventory tree. However, reporting of Missing, Compromised, or Fault statuses related to the actual hardware presence of GPIO will not occur.

External USB Audio

When enabled, you can connect an external audio device to the USB input and route audio to and from that device. See External USB Audio Device In and External USB Audio Device Out.

Telephony

Telephone Country

Select the country in which the telephone service resides.

Telephone Tone Output

When 'Yes' is selected, the Ring, Entry, Exit, and DTMF tones are fed to a separate output channel (Tone Output) on the POTS In component. These tones can now be routed independent of the voice audio.

Enable Call Sync

Use the Call Sync component to simplify the integration of Q-SYS collaboration devices and calling systems. It synchronizes mute state, call controls, and LED light behavior across multiple calling components, including USB HID Conferencing, Softphone, and POTS Controller. See the Call Sync topic.

Clocking

(Core 110 Series models only)

Sample Rate

Selects the sample rate. Typically, 48kHz is used as the Sample Rate. In scenarios where Q-SYS is externally synchronized to a (video) house sync signal you would use 48kHz Pull Down as the Sample Rate.

Clock Source

The GPIO selection requires an external TTL level word clock or a GPS connection: pin 1 is signal, ground in is indicated by the ground symbol on either end of the connector. When you select GPIO In Pin 1 as the clock source, GPIO Pin 1 is no longer displayed. The clock source should be connected to pin 1 of the GPIO connector.

Clock Type

When the Clock Source is set to a GPIO pin, the Clock Type field is available.

USB Bridging – Common Properties

These properties appear based on the USB bridging capabilities of the Q-SYS device. Refer to the USB Video Bridge and USB Audio Bridge topics to see what Q-SYS Core processors and peripherals support USB bridging.

USB Bridge Name

User-defined name given to the USB Bridge, from 1 to 24 characters. The Name may contain ASCII letters 'a' through 'z' (case-insensitive), the digits '0' through '9', and the hyphen. Names cannot begin or end with a hyphen. No other symbols, punctuation characters, or blank spaces are permitted.

Zoom Compatibility

If you are using the HID Conferencing component to control a remote computer running Zoom, set this property to 'Enabled.' Otherwise, when controlling another conferencing app such as Skype for Business, set to 'Disabled' (default). When this property is enabled, the USB Bridge Name property is disabled, and the USB Bridge automatically uses the name of the device for compatibility with Zoom's allowed device list – for example, "Q-SYS Core 110f" or "Q-SYS NV-32-H".

Tip: Enabling Zoom Compatibility may improve the user experience with macOS conferencing solutions.

USB Video Bridge

Enable the USB Video Bridge to bridge Q-SYS Mediacast streams to USB, enabling you to view Mediacast video on a connected computer. This exposes the USB Video Bridge component in the I/O-USB Bridge Inventory tree. To see what Properties are available when the USB Video Bridge is enabled, see USB Video Bridge.

USB Audio Bridge

Provides the capability of passing audio via USB. When this is set to anything except 'Disabled', you can drag the Speakerphone and/or Sound Card components from the device's Inventory tree into your design. To see what Properties are available when the USB Audio Bridge is enabled, see USB Audio Bridge.

  • Disabled: (Default)
  • Speakerphone (1 x 1): Provides a speakerphone with an input and output component, each having 1 audio connection.
  • Sound Card (2 x 2): Provides a sound card with an input and output component, each having two (stereo) audio connections.
  • Speakerphone and Sound Card: Provides one speakerphone and one sound card with the same capabilities as described above.
  • Advanced – If supported, allows up to any combination of four speakerphone / sound cards.

Speakerphone Mode

This selection is available only when Speakerphone or Speakerphone and Sound Card is selected in the USB Audio Bridge property. Indicates if the Q-SYS design has Echo Canceling (EC) or Non-Echo Canceling (NEC). This information is provided to the PC or Mac operating system so it can determine whether or not to use its own echo canceling.

USB Bridging - Miscellaneous Properties

These properties appear based on the USB bridging capabilities of the Q-SYS device. Refer to the USB Video Bridge and USB Audio Bridge topics to see what Q-SYS Core processors and peripherals support USB bridging.

UVC Camera Control

When this is enabled (default), the camera can be controlled by far-end third party applications which support Relative Movement Commands. When disabled, the cameras cannot be controlled by the applications.

Video Formats

Select what video formats are allowed to pass from the Q-SYS device to the host application based on the capabilities of your USB infrastructure – USB 2.0 or USB 3.0. To see what video formats are available when the USB Video Bridge is enabled, see USB Video Bridge.

Tip: USB 3.0 allows for YUY2 formats, which use less compression and therefore have a higher quality image.

USB 2.0 Support

When set to Enabled, the USB Video Bridge allows video formats compatible with USB 2.0 and 3.0 connections. When set to Disabled, the USB Video Bridge only allows USB 3.0 connections. To force support for USB 3.0 and HD formats exclusively, set this property to Disabled and set the Video Formats property to HD YUY2 Formats. The default is Enabled.

Graphic Properties

Label

Use the Label property to change the name of the component in the schematic. The Label property defaults to the component name. To learn more about renaming schematic elements, see Organizing Your Design.

Position

The coordinates reference a specific place in the schematic - for example,"100,100" (horizontal, vertical). 0,0 is the upper left corner of the schematic.

Fill

Sets the fill color of the component in the schematic.

Script Access Properties

Code Name

Displays the currently assign name for control access. You can use the auto-assigned name or customize it. Q-SYS will automatically check all Code Names in the design to ensure name is unique.

Script Access

Defines whether the component will be accessible by script and/or externally, or not at all. Choices include All, External, None (default), and Script.

Tip: Use Script Programmer Mode to quickly view the Script Access setting directly on the component in the design schematic without the need to disconnect from the Q-SYS Core processor.

Dialing

Dial String

The number of the phone or device you are calling. This number is a numeric text string entered by either the Keypad, keyboard, or using the Dial String Control Pin.

Backspace Key

The Backspace key deletes the last character typed, and can continue deleting one character at a time.

X (Clear Key) 

The clear key (X) clears the entire Outgoing dial digits field.

Progress
