the basic limit you should be aware of is the number of headsets in one area before DeCt channels are re-used:
- 80 headsets for eu DeCt (normal audio), or 40 headsets for eu DeCt (wideband audio)
- 45 headsets for us DeCt (normal audio), or 22 headsets for us DeCt (wideband audio)
the use of wideband audio gives an additional constraint as wideband audio reduces the number of headsets by
a factor of 2.
If the number of headsets in any one area is below the limit indicated above, there should be no performance
issues. even in those lower density situations, you are advised to separate bases from each other by at least 2 - 4m.
If you exceed the density limits, you should configure the products to operate in low-power mode. you must plan
using the following conservative average areas per headset and base-to-base distances:
- 25m
2
– 49m
2
for eu DeCt (i.e 5 – 7m between bases).
- 49m
2
– 100m
2
for us DeCt (i.e. 7 – 10m between bases).
Be aware of the fact that large metal objects or large glass windows, especially those covered with a metallic
layer, create many radio reflections. this forces you to plan even more conservatively. the average areas are valid
for an average headset-to-base distance of < 5m — otherwise more conservative planning is needed.
the area referred to above depends on the building layout. It could be an open space office, or a set of collocated
offices separated by lightweight walls. Offices far apart, say >100m apart, or shielded by heavy concrete walls
should not be considered one area. the above planning figures are valid if most users are near their bases
(< 3m distance). If most users are > 5m away from their bases, you should roughly double the recommended area.

there are three possible kinds of audio link between your PC and the headset:
- audio link for music
- PC softphone link.
a two-way audio link for softphone communication (which includes hook commands)
- PC communication link.
a two-way audio link used for non-supported softphones and web conferencing (no hook commands are used)
In order that your web conference is not interrupted by incoming phone calls, you need to make a pseudo call for its
duration. this means that you need to open a PC communication link manually. Do the following:
1. On the base
touchscreen,
select PC as the
target phone,
as shown.

2. touch the PC
phone icon to
display the
PC

menu, as shown.
touch the

Communication
menu item.
