The “vs.” column shows the relationship between the DiffServ and IP precedence standards.
Since DiffServ offers more variants, the codepoint is permanently selected when translating IP
precedence into DiffServ: for example, the codepoint for the IP precedence “100”, for example,
becomes “AF31”. In the case of packet that leave HG 1500 in the direction of the LAN, the user
priority specified in the last column is set when IEEE 802.1p is active.
QoS can be activated for the second LAN interface as well as for the ISDN partner. For this
interface, the interface is extended by an additional transmission rate limitation. The function
of the quality evaluation corresponds to the ISDN peer procedure. The average transmission
rate is set in configuration data.
