Bit 7-5 – Precedence
Set the precedence of the datagram using the following values:
000(0) – Routine
001(1) – Priority
010(2) – Immediate
011(3) – Flash
100(4) – Flash Override
101(5) – Critical
110(6) – Internetwork Control
111(7) – Network Control
Bit 4 – Delay
When set to1 the packet requests a low delay.
Bit 3 – Throughput
When set to 1 the packet requests high throughput.
Bit 2 – Reliability
when set to 1 the packet requests high reliability.
Bit 1-0 – Unused
DSCP or Differentiated Service Code Point is another method for classifying
and managing network traffic on IP networks. This is also six bits and is
a newer alternative to the TOS bits. Diffserv aware routers use Per-Hop
Behaviours which define the packet forwarding properties associated with
each class of traffic. The Per-Hop Behaviour is determined by the DS field in
Ipv4 or Ipv6 header. The behaviour can be either:
Default – Typically best-effort traffic. Set to 000000.
Expedited Forwarding – dedicated to low-loss, low-latency. Set to 101110.
Assured Forwarding – Assured delivery under prescribed conditions:
Class 1
Class 2
Class 3
Class 4
Low Drop AF11 (DSCP 10) AF21 (DSCP 18) AF31 (DSCP 26) AF41 (DSCP 34)
Med Drop AF12 (DSCP 12) AF22 (DSCP 20) AF32 (DSCP 28) AF42 (DSCP 36)
High Drop AF13 (DSCP 14) AF23 (DSCP 22) AF33 (DSCP 30) AF43 (DSCP 38)

SNMP Settings
Traps can be configured to monitor audio input levels on the PS-SEND. The
traps are triggered by a level of audio either below or above the set trigger
levels.
Trap Target IP Address
Enter the IP address of the trap target destination.
Low Audio Level
The lower limit of the audio, before a trap is triggered.
High Audio Level
The higher limit of the audio, before a trap is triggered.
Trap Repeat
Repeat the trap after this amount of time if the audio remains out of range.
Silence Timeout
The amount of time that the low limit has to be breached before sending a
trap.
Control Settings
UDP Command Port
The port on which the PS-SEND can receive commands via UDP. To disable,
set to 0.
