Technical Concepts
Quality of Service (QoS)
fault value is set ("identical"), nothing is translated; with the values "DiffServ" or "IP Prece-
dence", 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 generated by the HG 1500 are split into five groups
(e. g. the VCAPI server, H.323 Gateway). You can set which codepoint is to be used for marking
the packets for four of these groups.
● Voice Payload for IP telephony (Voice over IP)
● Call signaling for connection setup with H.323/SIP
● 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 different DiffServ codepoints and Siemens default settings are displayed in the following
table.
