packetassist automatically adapts video meeting transmissions to current network conditions, while ensuring optimal video and audio performance.
for example, if mediaconnect detects the possibility of network congestion, it automatically decreases the transmission rate until it finds the optimal point for continuing transmission, while maintaining good video quality at this lower rate. a message appears on the screen stating that the system is adjusting itself.
the qos properties dialog box contains properties for controlling the type of quality of service that will be used for transmitting packets from the specified meetingpoint user. a password is required to open this dialog box, and we recommend that only system administrators with knowledge of qos make any changes, if required.
· to view and change qos properties
1. press [menu]. the main menu opens. select tuning h.323.
2. in the tuning h.323 dialog box, navigate to the qos tab and then to password.
3. enter the administrator password. the default password is 1234.
4. set qos properties as follows:
priority type select the type of qos used for transmitting packets
during heavy network congestion conditions.
■ no priority - network transfers packets using
normal best-effort (or routine) packet
transmission.
■ ip precedence - network gives priority to certain
types of bits (video, audio, control) according to the
eight levels of ip precedence.
■ diffserv - network transfers packets according to
specific needs of the sending application.
priority values for video, audio, and rtcp (real time control
protocol) priority, enter an appropriate priority level.
the item with the highest priority number will be sent
first, the item with the next highest number will be sent
second, and so on.
the priority levels vary, depending on whether the
selected priority type is ip precedence or diffserv.
5. to return to the default qos values, press the red reset softkey.6. press [ok] to save the qos settings and close the dialog box.
