If you feel that changing the default values is imperative to the working of the network, the
following table is provided to give the hexadecimal values for various settings:
A bit mask is also set with the UI in hexadecimal form. The mask is used during the lookup
phase of ToS and screens out the insignificant bits. For IP precedence, the mask should be set
to
e0
(this is the default value). For DSCP, the mask is
fc
.
♦ Important Note ♦
These values are set to work with the Alcatel VoIP
modules. DO NOT attempt to change them unless you
are an advanced user with detailed knowledge of
Alcatel products and how they interact.
