About the device

The RTX745x device is an EHS/USB wireless base station that provides USB connectivity to PC/laptop/desktop phones and DECT connectivity to RTX725x headsets/DECT speakerphones. It is designed as a Plug & Play solution, meaning that no additional driver installations are needed.

The figure below (Fig.1) illustrates the high-level description of the communication possibilities of the device. The RTX745x base is connected to a host (PC or desktop phone) with a USB interface. It acts as a DECT base station for RTX725x headset and DECT speakerphone.

The RTX745x serves as a base and charger for the RTX725x series headsets. The primary application is within call centers and office environments allowing the user access to internet/VoIP calls, music playback via the PC/mobile phone, and desk phone connectivity.

Device overview

The drawings below illustrate the dimensions of the device (Fig. 2).

The base includes a 2.4-inch 240×320 TFT display for status and configuration. Furthermore, it has 3 keys for call control handling (hook off, hook on and mute), a clickable scroll wheel, and a key for easy menu navigation (Fig.3).

Further details on the functionality of the keys can be seen on the table below:

Input	Functionality
Hook off	Answer call (short press)

Swap between calls (short press)
Swap between lines (double press)
Hold/Retrieve call (short press)
Hold active calls and accept the incoming call (long press)
Hook on| End call
Reject call
Mute| Toggle mute
Back key| Return to the parent menu of the current submenu
Leave the settings menu
Scroll wheel| Open the settings menu
Select an item in the settings menu
Scroll to the next item in the settings menu
Scroll to the previous item in the settings menu
Adjust earphone volume

Spare battery charging

The base also includes a separate charger for a spare battery. The battery is placed on the back of the base, as shown below (Fig.5).

Ringer configuration

The RTX745x has a built-in ringer for audible alerts for the user. The audio settings of the ringer can be configured via the PC Setup tool or the base menu. The ringer may be muted by selecting “Silent mode” in the PC Setup Tool.

Connect to VoIP multicell systems

The RTX725x headset and RTX7451 base together can integrate into VoIP multicell and dual cell systems. The base will register on behalf of itself and the headset. The two registrations are independent but will be linked logically as one unit on the VoIP system. The purpose of this integration is to hand over the user’s calls to the VoIP system for the user to be flexible in terms of location.

Configuration tool (PC tool)
The RTX745x and RTX725x parameters can be configured via an external PC configuration tool (PC tool). Moreover, the tool is used to firmware upgrade both devices and do upgrades of the tool itself. The PC tool is available for Windows and macOS. The screenshots below display an example of the GUI interface of the tool. Logos and colors can be adapted to customer needs. For more information about the tool, please refer to 1.6 References/Related Documentation.

User interface

As mentioned above, the RTX745x base supports a 2.4-inch 240×320 TFT display which has a user-friendly interface (UI). The UI is designed to be operated at an arm’s distance, meaning that the status bar is large and visible (Fig.8). However, the icons shrink in size when navigating through the device’s menu, yet still, allow the user to see the status (Fig.9).

The following table aims to introduce you to the available icons on the UI of the device.

Icon	Description	Function

DECT registration status interface

The following screenshots represent the interface during a DECT registration (Fig.10).

Call activity on the base

To have call activity on the base, a master headset must be registered and locked to the base. If the master headset loses connection during call activity, all the calls will be terminated.

Incoming call

The base will notify the user with visible and audible indications whether an incoming call is from EHS or USB line. If both lines are in an idle state and an incoming call is received to one of the lines, the base rings and displays the call (Fig.11). However, if there are two simultaneous incoming calls from two different lines, the active control is made by the first incoming call (the first that came is served first). The second incoming call cannot be accepted by the base until the first incoming call has been answered or ended, or the line is swapped manually by the user (Fig. 12). In case of having one of the lines is occupied (inactive call), the new incoming call will be displayed as waiting in a queue (Fig.13).

Active call

When a call is active, the base displays the active call and the audio path is connected between the far-end party and RTX725x headset. It is not possible to have more than one active call on a single line at the same time.

On-hold call

When a call is put on hold, the base displays a hold call status, and the audio path is disconnected between the far-end party and the RTX725x headset (Fig.15 Two calls, one on hold). It is not possible to set EHS’s active call on hold by the base.

Multiple calls

There is more than one call existing in a single line. EHS line does not support multiple call.

Multiple line

There is more than one call existing in different lines.

Active & Inactive line

When a line is active, the base displays the active line and the audio path is connected via the line. It is not possible to have more than one active line at the same time.
When a line is inactive, the base displays an inactive line and the audio path is disconnected via the line. It is not possible to have manual call control of the base when the line is inactive.

Call termination

All calls will be terminated when the master headset loses link or is placed on the cradle.

Line swapping

In this case, two calls are established in two different lines, one of them is being the active call in the active line. To make the line swapping simpler, the active line is swapped automatically depending on-call activities change. It can be one of the following scenarios:

User makes an outgoing call by softphone or desktop phone.
User retrieves USB held call by softphone.
User swaps USB call by softphone.
The user accepts an incoming call.
The call from the first active line is ended and another call exists in the second inactive line.

The user can also swap the line from the base manually. When a line is swapped successfully, between two different lines, a visible indication is shown on base.

Microphone muting

Microphone muting control is separated into two muting statuses. Each line has its own microphone muting control.
When the line is switched, the related microphone muting control will also be switched.

Volume control

Similar to the microphone, the volume control is also divided into two sets of volume. This means that each line has its own volume control. When the line is switched, the related volume control will be also switched.

Features overview

This section aims to introduce you to the available features on the RTX745x base. Some of the features will be briefly described through the sections below, whereas the main highlights will be presented via a table with function descriptions.

Soft client support

The base, combined with one of the RTX725x headsets, supports the audio and USB API of the following applications:

Skype for Business
Microsoft Teams
Customer client support implemented in the PC tool

The RTX745x base can be used with both PC Windows and macOS.

EHS interface

The RTX7451 supports EHS phones. The base is prepared to be compatible with various EHS standards. This is done by having a slider switch that enables 6 separate HW configurations for the audio routing. The PC Setup tool is used to configure the optimal settings for the SW configuration.
The RTX725x supports 2 active calls, meaning that the 3rd incoming call will be rejected or ignored. If during a call the user receives an incoming call, the call can be rejected by double-pressing the Multi-Function key or accepted by long-pressing the same key. The long press will answer the incoming call and put on hold the current one.
