Using A 3616, 3620 Or 3626 Phone - Avaya 3600 Series Installation Instructions Manual

2.1 Using a 3616, 3620 or 3626 Phone

Use the following process to perform a site survey using a 3616, 3620 or 3626 phone.
1. With the phone powered off, simultaneously press and hold Power On/Start Call and Power Off/End Call.
2. After hearing two beeps, release Power On/Start Call, then release Power Off/End Call.
3. If an admin password has been set, it must be entered to display the Admin menu.
4. Scroll to and select Diagnostics. Select Run Site Survey.
5. Walk the entire coverage area while viewing the display.
6. Numbers racing across the wireless phone display indicate access point information is being obtained. A Waiting
message indicates the system is not configured properly and the wireless phone cannot find any access points.
7. The FCN key toggles between the three coverage modes described below.
a. Detect dBm Coverage
Press FCN to display -dBm on the base of the display. The phone is now showing the signal strength of the
top four access points it can contact.
XXX1 YY XXX2 YY
XXX3 YY XXX4 YY
-dBm
· XXX1 through XXX4 are the last four digits of the MAC addresses of the access points. The access point
with the strongest signal to the phone is displayed first, followed by the next three access points in order
of signal strength.
· YY is the power level in dBm at which this wireless phone heard the associated access point. YY
represents negative dBm and lower numbers represent stronger signals. At least one access point's
reading should be stronger than -70 dBm in all areas.
· Note any areas that have inadequate dBm readings. Coverage issues are best resolved by adding and/or
relocating access points.
b. Detect Overlaps and Conflicts
Press FCN to display Chnl on the base of the display. The phone shows the channel each access point is
using. Ideally each access point should use a unique channel. It is preferable that no overlaps exist. If that is
not possible, then any location that shares two access points with the same channel should also show at least
two access points with stronger signals that do not conflict.
XXX1 ZZ XXX2 ZZ
XXX3 ZZ XXX4 ZZ
Chnl
· ZZ is the channel number that the access point is using.
c. Confirm Supported Data Rates
Press FCN to display Det1 on the base of the display. The phone shows details for an individual access point.
Use this to confirm signal strength and supported data rates. Use the right and left arrow keys to display
different access points.
#:
dB Ch
Detl
· #: the number (1-4) of the access point.
· Full MAC: the MAC address of the access point.
· dB: the signal strength of the access point.
· Ch: the channel of the access point.
· 1b2b5b11b is an example of the data rates that may be displayed. Each data rate (1, 2, 5.5, or 11Mbit/
sec) supported by the access point is shown. Those rates in the Basic Rate set (sometimes referred to as
"required" rates) are indicated by a 'b' following the rate number. The Supported and Basic data rate(s)
should be the same on all access points.
8. When testing is complete, to power off the wireless phone press Power Off/End Call.
