MP-202 Telephone Adapter 8. Quality of Service (QoS)
8.5 Class Statistics
The gateway provides you with accurate, real-time information on the trafc moving
through your dened device classes. For example, the amount of packets sent, dropped or
delayed, are just a few of the parameters that you can monitor per each shaping class.
To view your class statistics, press the QoS button on the sidebar and then click the Class
Statistics tab. The following screen will appear (refer to the gure).
Note: Class statistics will only be available after dening at least one class
(otherwise the screen will not present any information).

8.6 Configuring Basic VoIP QoS
The 'Traffic Shaping' feature only ensures priority to calls that are originated inside the MP-
202. When giving VoIP priority over data, the bottleneck is effectively moved from the
Cable / ADSL modem into the MP-202. To give priority to calls from the LAN, you must
define a traffic priority rule (for SIP and RTP from the device on the LAN).
This section recommends a minimal QoS configuration that ensures sufficient QoS for
VoIP calls when the gateway is connected behind a broadband (cable or DSL) modem with
limited uplink bandwidth and the user runs bandwidth-consuming applications on their PC.
Since most modems do not have any priority mechanisms, the Tx bandwidth of the
gateway should be limited according to the modem’s uplink bandwidth. Since the gateway
will automatically give higher priority to VoIP packets (in its internal queues), it is not
necessary to define traffic shaping classes.
