Using and Hx1/Hx2 with a QOR Console

Updated 1 month ago by John (JP) Powell

Scope

This document explains how to configure an iQ source profile and GPIO remote control for an Hx1 or Hx2 system.

Description

The Hx1 and Hx2 are Telos' most basic POTS phone systems. The Hx1 and Hx2 work similarly to the Hx6 and iQ6, except they operate entirely in hardware, are in fixed hybrid mode only, there is no Livewire available, and there is no control possible from a VSet or screening application.

This article will show you how to configure a source profile in your iQ system and how to make a cable to connect the Remote port of the Hx1 /2 system to an Axia-style GPIO port for fixed hybrid style control from the console.

In the examples below, we will be using Analog input(s) and output(s) 1 and 2(Hx2).

1. Configure Audio I/O

  • Go to the QOR's Inputs page and label the appropriate input. You can also trim the input gain if needed here.
  • Next, Go to the QOR's Outputs page and label the appropriate outputs. Set the Output mode drop-down box so that it has the word "To:" in front of the local inputs you just selected in the previous step.

When an Axia output or network destination is set to "To: Source," that output or destination will be a backfeed from the engine. In this case, the backfeed is a mix minus of the specified input. Click here for more information about this.

2. Configure Source Profile

  • Create a Phone source profile for the Hx1 or Hx2.
  • Set the Source Input to Analog 1
  • Use Signal Mode = Left if there is only audio on the left input.
  • Configure the Logic Port section as Exclusive with GPIO Ready disabled
  • Set GPIO Hybrid Control to either Channel ON Answers Hybrid or Channel or Preview ON answers hybrid
  • Set Feed to source to be the desired mix-minus mode. The default is Auto.
  • Apply your changes
Note: Settings for Hybrid for Telos Phone do not matter in this configuration since we are communicating with a phone system via physical GPIO closures instead of Livewire Control Protocol. Here, it is configured for "Fixed Hybrid #1" just as a reference, since we will be treating this as a fixed hybrid at the console.
If you have an Hx2, note that you'll need to have a second source profile configured for Hybrid/Line 2.

3. Configure GPIO

QOR Engine

When using the physical audio I/O of a QOR engine, you will need to configure 1 GPIO port (or 2 ports for Hx2) at the QoR engine. In this case, GPIO via a Livewire node is not possible.

  • Navigate to the QOR's GPIO configuration web page
  • Select a Local GPIO port (or 2 if configuring for Hx2) and set Logic for to the physical audio input(s) being used.
  • Apply your changes.

Livewire

If you're using a Livewire node for the Hx hybrid's audio I/O, you can use either a Livewire GPIO node or the QOR's GPIO section for control.

  • Navigate to the GPIO configuration section of your node or Local GPIO Configuration section of QOR engine
  • Set Logic for to Livewire (QOR Engine Only)
  • Set the Livewire channel to the same value used at the Audio node for the Hx hybrid.
  • Apply your Changes.
Note that a second port will need to be configured for Hx2 Hybrid 2.

3. GPIO Wiring:

  • Shunt Axia Output Common (Pin 7) to Axia Ground (Pin 8), and connect to Hx Ground (Pin 1)
  • Connect Axia Start Pulse Output (pin 4) to Hx Hybrid On Input (pin 2)
  • Connect Axia Stop Pulse Output (Pin 5) to Hx Hybrid Off Input (pin 3)
Notice that a second Axia GPIO port is needed for controlling Hx2 Line 2. Wire the second port identically to the first: with the same ground path (in parallel), except use Hx2 pins 5&4 instead of 3&2 as shown in red above for the second Axia port.

More Info / Further Reading:

Take a look at the GPIO section of the xNode's user manual (To find, Click Here) for a more thorough description of Axia GPIO functions, modes, specifications and pinouts. You may also want to reference the Remote Control section of the Hx1 / Hx2 manual. (To find, Click Here) for the full specification of the Hx's GPIO port.
