•
Capture on interface: Network interface from where the capture should be made. The Local
Loopback Interface option is available for QuadroM units only and is used to capture the
traffic within the unit.
•
Stop after receiving count packet: Number of packets to be captured.
Please Note: After the capture is initiated, the system will create a file and log all the packets
meeting the specified criteria into it. Specifying a large number for this setting or leaving it
unspecified and making a long capture may consume system resources and cause a system
reboot.
•
Restrict to host: Packets can be captured from the specified IP address.
•
The Capture All Packets and Capture Specific Protocol Packets radio buttons are used to
choose between capturing all the packets on the interface and restricting the capture to
specific packets only (ARP, SIP, DNS, and RTP).

The following settings are found on the Trunk – Echo page:
•
Echo Delay: Delay between the original voice and the corresponding echo signal. For the
meaning of the DSP Echo Tail, DSP Echo NLP Diff, and DSP Echo NLP Shift, see section

DSP echo canceller if no echo is detected on the call, i.e. if the call path does not contain any
echo source, such as FXO or FXS interfaces.
