MG-PRI/PRA
13.1.5 Quality of Service (QoS)
To distinguish transmission quality of signaling control data, MG-PRI/PRA can specify Type of Service
(ToS) of IP Precedence and Differentiated Service (Diffserv). The packets mapped by Diffserv are con-
trolled per switch, which is called Per Hop Behavior. The QoS is specified depending on your network en-
vironment. The following shows the packet types of IP Precedence and Diffserv.
Note:
Telephony Server (Internal PHI-PRI) does not control packets using ToS.
Prec= PRECEDENCE (3 bits)
D=Delay (0/1= -/immediate sending is emphasized)
T=Throughput (0/1= -/transfer speed is emphasized)
R=Reliability (0/1= -/high reliability is emphasized)
C=Cost (-/low cost)
