1.1.1.37 ASI-IP-GTW Configuration
The number entered into the Type of service (TOS) field on
ASI-IP-GTW IP TX configuration menu defines all 8 bits. The value used
should be in accordance with traffic engineering policy of network and
should be in the range from 0 to 255.

12.3 Layer 2 priority
Prioritisation can also be supported at layer 2 for the case when VLAN
tags. The 802.1q VLAN tag has 3 bits for setting the Class of Service
(COS). The operation is further defined in 802.1p. The COS bits will be
handled in the same ways as diff-serve or precedence bits with regard
to packet classification in the network
tags. The 802.1q VLAN tag has 3 bits for setting the Class of Service

1.1.1.38 ASI-IP-GTW Configuration
The COS priority is entered on the VLAN configuration tab on the
ASI-IP-GTW IP TX configuration menu, in the field named VLAN
Priority. A value in the range from 0 to 7 should be inserted. This
value will be directly transferred to 3 user priority bits in the VLAN
header.
More information on quality of service issues and configuration can be
found in the literature e.g. router configuration guides.
