ESSID
ESSID (Extended Service Set ID) is an option used by 3616, 3620 and 3626 phones to establish the
SSID of the wireless network. Broadcast ESSID must be enabled in the access points for ESSID
learning to function.
Overlapping wireless systems complicate the use of ESSID learning as the wireless phone in an
overlapping area could receive conflicting signals. If this is the situation use
Static Entry
or
Learn Once
.
•
Learn Once
*Default
The Learn Once option allows the wireless phone to scan all ESSIDs for a DHCP server and/or
TFTP server. Once either is found, the wireless phone retains the ESSID from whichever access
point it associates with at that point. When overlapping wireless systems exist, the Learn Once
feature allows the wireless phone to use only the ESSID established at first learn at all
subsequent power on. This ESSID is retained by the wireless phone until the ESSID option is re-
selected.
•
Learn Always
The Learn Always option allows the wireless phone to automatically learn the ESSID at each
power on or loss of contact with the wireless LAN (out of range). This may be useful if the
wireless phone will be used at more than one site.
•
Static Entry
If your access points do not accept broadcast ESSID or if there are overlapping wireless systems
in use at the site, enter the correct ESSID manually:
1. On the keypad, press the first digit/letter of the ESSID. The digit is displayed.
2. Press the first digit/letter of the ESSID again, to scroll through the letters associated with
that key.
For example, if you press 2 repeatedly, you will see 2, A, B, and C, a, b, and c.
