Headset
The Avaya EHS adapters are compatible with all Jabra GN 9350 (Rev. 1.17 or higher) and GN
9120-EHS (available in Q208) wireless office headsets. The Avaya EHS adapter is not backwards
compatible with older GN 9120 standard versions.
The adapters all support auto sensing, and will detect if the AUX port is configured in RHL
(standard GN 1000 mode) or DHSG mode.
The interface adapters work in both modes (please see details below).
Troubleshooting
When there is a problem it is important to establish if it’s related to the audio not being present, or
to missing Electronic Hook Switch signaling.
A good start is to ensure that the headset is working, and that audio works in the headset. Then the
user can connect the EHS adapter, check to see if the audio is still working, and after that, check
that the Electronic Hook Switch functionality is working as well.
Please note that the incoming call signaling only is supported with the Avaya EHS-1 adapters.
When an incoming call arrives, the first ring is signaled in the headset earpiece.
Subsequent rings
are not signaled to the headset user.
1. Make sure the headset is adjusted to the RHL Hook mode.
If the GN headsets supports both DHSG and RHL hook interface, adjust it to RHL first. When
everything works, the user can switch to DHSG if desired.
2. Connect all cables
Avaya EHS interface adapters will connect between the EU24/ ADJ port on the phone and the AUX
port on the headset.
The audio is connected through the cable that was supplied with the headset – between the headset
port on the phone and the phone port on the headset base station.
With the Avaya EHS-2, and EHS-5 adapters, the single cable in one end of the interface adapter
plugs into the headset port on the phone, and the two cables on the other side plug into the AUX
port and phone port on the headset.
3. Listen for dial tone & try the EHS function
When the headset is removed from the base it must make a click sound and establish a link.
The phone should now go off hook and a dial tone should be present in the headset earpiece.
If no dial tone is present try the following:
1. Press the headset button a couple of times, toggling the audio link up and down. See if the phone
catches up and starts to react on the signaling from the headset.
2. Press the headset button on the phone while the headset is off hook. Now a dial tone must be
heard in the headset earpiece.
