HG 1500 V3.0
If a routing partner can only work with one of the two standards (DiffServ or IP precedence,
for example an older router that only works with IP precedence), then HG 1500 V3.0 can translate
the ToS field accordingly. This can be set for each ISDN partner or DSL/LAN2/PPTP interface
via "QoS Capability". When the default value is set ("identical"), nothing is translated; with
the values "DiffServ" or "IP Precedence", translation is performed on the basis of the table below,
if data is not entered in the field in accordance with the standard set.
In the case of IP data traffic, the IP packets that generate HG 1500 V3.0 are split into five
groups (for example the vCAPI server, H.323 gateway). You can set which codepoint is to be
used for marking the packets for four of these groups. This is configured under "Basic Settings
> QoS priority classes":
● Voice Payload for H.323 telephony (Voice over IP)
● Call Signaling for connection setup in H.323
● Data Payload, for example, for IP networking with fax or modem
● Network Control, for example, SNMP traps
The remaining data traffic is marked "disabled", that is 00.
The following table shows the relationship between the various codepoints of DiffServ, IP precedence
and the "User Priority" field in the Ethernet header.
