TECHNICAL RELEASE NOTE OF VoWLAN
R4.2.1
Ed. 01 / 03 March 2010 11 TC1308
Two solutions:
• Before existing U-APSD client is upgraded to this 120.023 version, admission control must be
set on the OAW controller (set the ACM to 1 for Voice and Video access categories in EDCA
AP and Station profiles, refer to TC1315 Example of OAW Configuration Technical
Communication). Any other U-APSD client on the WLAN will also be required to use ACM for
Voice and Video access categories.
Or
• During existing U-APSD client is being upgraded to this version, user must select to disable
admission control (i.e. select Optional WMM-AC) one by one in each handset for this WMM-
AC option => this disabling action of AC feature must happen during the upgrading.
Otherwise, the upgrading procedure cannot finish properly.
Technical communication TC1315 Example of OAW Configuration gives information on AOS
version installation, licenses installation and ACM configuration. Refer also the System Technical
Documentation of OmniPCX Enterprise R9.1 or OmniPCX Office R7.1, WLAN section.
5.3 Installation of 120.023 version
There is compatibility between the successive MIPT versions included in system patches, up to
120.021 (system dependant). But this basic compatibility is broken with 120.023 MIPT version if the
WMM-AC QoS is not managed as said previously.
5.3.1 Upgrade to 120.023 on OmniPCX Entreprise
The binary files of software version 120.023 and the HAT application can be found on the BPWS in
section Technical Support > Software download > Phones > IP Touch WLAN.
To ensure the compatibility of the new 120.023 MIPT version with the existing VoWLAN topology
onsite, the following steps are recommended:
• Deactivate the Reset for Update for all
the 310 & 610 handsets.
• This management is possible by modifying the following mgr parameter for all 310 & 610
WLAN handsets.
In Users > Tsc Ip User: Reset for Update authorized + NO
• Use an external TFTP server available on the LAN for some targeted MIPT for compatibility
test.
In case of Static IP configuration for MIPT, the IP address must be configured in the ‘TFTP
server IP’ field available from the administration menu of the handset.
In case of dynamic IP configuration for MIPT, configure the 66 option in the DHCP server
available on the LAN to input the value of TFTP server as IP address. This option will be used
to download firmware from the TFTP server.
If you force the handset not to download firmware from TFTP, input 255.255.255.255 value
into the 66 option.
Recover MIPT binaries archive and decompress the files content on the TFTP target directory:
