Overview

This document outlines how to resolve a humming noise issue when connecting a Jabra wireless headset to an Avaya 1400/9400/9500 series desk phone. It provides detailed instructions for two primary connection methods: basic audio connection using the Avaya handset port and remote call control using the Jabra GN1000 remote handset lifter and the Avaya handset port.

Function Description

The core function of this guide is to enable users of Jabra wireless headsets, such as the Jabra Pro 920, Jabra Pro 9450, or Jabra Motion Office, to connect their devices to specific Avaya desk phones (1400/9400/9500 series) without experiencing an undesirable humming noise. This noise typically occurs when the headset is connected directly to the headset port of the Avaya phone. The document offers alternative connection strategies that reroute the audio through the handset port, thereby bypassing the problematic headset port and eliminating the humming.

The first method, "Basic audio connection using the Avaya handset port," focuses on establishing a fundamental audio link for calls. This setup allows the user to hear and speak through the Jabra headset, but requires manual interaction with the desk phone's handset to answer or end calls. The Jabra headset acts as an audio conduit, replacing the traditional handset for improved comfort and mobility, while the desk phone retains its primary call control functions.

The second method, "Remote call control using the Jabra GN1000 remote handset lifter and the Avaya handset port," enhances the basic connection by introducing remote call control capabilities. By integrating the Jabra GN1000 remote handset lifter, users can answer and end calls directly from their Jabra wireless headset, eliminating the need to manually lift or replace the desk phone's handset. This provides a more seamless and convenient user experience, particularly for those who frequently make or receive calls and benefit from hands-free operation. The GN1000 physically lifts the handset when a call is initiated or answered remotely, effectively mimicking the manual action.

Both methods aim to provide clear, hum-free audio communication through the Jabra wireless headset, leveraging the Avaya desk phone's existing infrastructure while mitigating a common audio interference issue. The guide ensures that users can maintain productivity and enjoy the benefits of a wireless headset without audio quality compromises.

Usage Features

The document details several usage features related to connecting and operating Jabra wireless headsets with Avaya desk phones.

For the Basic audio connection using the Avaya handset port, the connection process involves three key steps:

  1. Disconnecting the Avaya handset cable: The existing handset cable must be removed from the handset port on the desk phone.
  2. Connecting the Avaya handset cable to the Jabra base: This cable is then plugged into the designated handset port on the Jabra base unit.
  3. Connecting the Jabra phone cable: A supplied Jabra phone cable is used to link the Jabra base's line port to the handset port of the Avaya desk phone. This establishes the audio path.

Once connected, answering and ending calls with this basic setup requires manual interaction with the desk phone:

  • Answering a call: While wearing the headset, the user must manually lift the desk phone's handset and place it down next to the phone. This action signals the phone to route the audio through the headset.
  • Ending a call: To end a call, the user must manually place the handset back onto its dedicated area on the desk phone.

A crucial usage feature for this basic connection is the Jabra base setting "Open desk phone line when undocked." This setting must be "on" to ensure an active link between the headset and the base when the handset is lifted. If the headset is undocked and the link becomes inactive, the user can reactivate it by pressing the Multifunction (answer/end) button on either the headset or the base (depending on the product). This ensures consistent connectivity.

For Remote call control using the Jabra GN1000 remote handset lifter and the Avaya handset port, the connection process is expanded:

  1. Disconnecting the Avaya handset cable: Similar to the basic connection, the existing handset cable is removed from the desk phone's handset port.
  2. Connecting the Avaya handset cable to the Jabra base: This cable is then connected to the handset port on the Jabra base.
  3. Connecting the Jabra phone cable: The supplied Jabra phone cable links the Jabra base's line port to the handset port of the Avaya desk phone.
  4. Mounting the Jabra GN1000: The GN1000 lifter is mounted underneath the Avaya handset, following its specific setup guide. This physical integration allows the lifter to raise and lower the handset.
  5. Connecting the Jabra GN1000 cable: The GN1000 cable is connected to the AUX port on the Jabra base, establishing the control link between the lifter and the headset system.

With the remote call control setup, answering and ending calls becomes more streamlined:

  • Answering a call: The user can undock the headset from the base, or, while wearing the headset, press the Multifunction (answer/end) button on the headset or the base. The GN1000 will automatically lift the desk phone's handset.
  • Ending a call: The user can dock the headset back into the base, or press the Multifunction (answer/end) button on the headset or the base. The GN1000 will automatically place the desk phone's handset back down.

A key usage feature for remote call control is ensuring the Jabra base setting "Electronic hook lifter" is configured to show "Jabra GN1000" as the selected solution. This ensures proper communication and functionality between the base and the lifter for remote call management. The document advises consulting the user manual for the specific Jabra headset for more details on these settings.

The guide emphasizes that the level of humming noise can vary depending on the speaker volume set on both the desk phone and the Jabra wireless headset, implying that users might need to adjust these volumes to find an optimal balance if any residual noise persists after implementing the recommended connection methods.

Maintenance Features

While the document primarily focuses on connection procedures and usage, it implicitly touches upon maintenance through its emphasis on correct setup and configuration, which are crucial for the long-term, hum-free operation of the devices.

  • Correct Cable Management: The instructions for connecting specific cables to designated ports (e.g., Avaya handset cable to Jabra base handset port, Jabra phone cable to Jabra base line port and Avaya handset port, GN1000 cable to Jabra base AUX port) highlight the importance of proper cable management. Incorrect connections can lead to functionality issues or, in the context of this document, the persistence of humming noise. Ensuring cables are securely and correctly plugged in prevents loose connections that could degrade audio quality or cause intermittent functionality.
  • Firmware and Software Settings: The mention of Jabra base settings like "Open desk phone line when undocked" and "Electronic hook lifter" points to the importance of maintaining correct software or firmware configurations. Users are advised to ensure these settings are appropriately enabled ("on" for the former, "Jabra GN1000" selected for the latter). This implies that users should be aware of how to access and modify these settings, which might involve consulting the headset's user manual or accessing a configuration interface. Keeping these settings correctly configured is a form of digital maintenance that ensures optimal performance.
  • Consulting User Manuals: The document explicitly directs users to "Jabra Support to search for and find the relevant user manual for your product" for more details on specific Jabra headset settings. This is a critical maintenance feature, as user manuals often contain troubleshooting steps, detailed configuration instructions, and information on device care that can help prevent issues and maintain optimal performance over time. Regular consultation of these resources can help users understand their device's capabilities and limitations, and how to address minor issues before they escalate.
  • Physical Integrity of Components: Although not explicitly stated as a maintenance task, the instructions imply the need for the physical integrity of the components. For example, the Jabra GN1000 remote handset lifter needs to be "mounted underneath the Avaya handset according to the Jabra GN1000 setup guide." This suggests that the lifter, cables, and base unit should be kept in good physical condition, free from damage that could impede their function. A damaged cable, for instance, could reintroduce audio issues.
  • Volume Adjustment for Noise Mitigation: The note about the humming noise varying with speaker volume on both the desk phone and the headset suggests a user-level maintenance action. Users might need to experiment with volume settings to find a sweet spot that minimizes any residual noise, even after the primary connection issue is resolved. This ongoing adjustment is a form of operational maintenance to ensure the best possible audio experience.

In essence, while direct "cleaning" or "repair" instructions are absent, the document guides users toward maintaining optimal performance through correct setup, configuration, and resource utilization, all of which contribute to the longevity and effective operation of the Jabra wireless headset system with Avaya desk phones.
