Installation, Operation, Maintenance Manual
DSP traces are useful for capturing voice/data directly from a DS0 channel. To setup
a DSP trace take the following steps:
1 On a PC run the UDP2File utility.
2 Select a suitable trace file name.
3 Determine the UDP port. Note: if there is a firewall between the gateway and the PC
ensure that it is not blocking the UDP port you select for capturing the data.
4 Press the GO button. The UDP2File utility will start to collect the trace messages when
they are sent from the gateway.
5 Activate the Web page by entering <MG 3500 TP board IP address>/FAE in a browser
window and choose the Packet Recording tab (e.g.,http://10.8.8.101/FAE). See Figure
24-8 below.
6 Use the user and password, which is the same for the unit.
7 Set the channel\channels to be recorded. It is not recommended to record more than
10 channels at once.
8 In the record points line check all the check boxes: DSP TX & RX, RTP TX & RX and
events.
9 Do not use trigger or filter.
10 The port must be the same port as in the UDP2File application.
11 Press 'Apply New Settings'
12 Go to the UDP2File application and press 'Go', the application records packets sent on
the selected port.
13 Go to the web page and press 'Record', the board sends the packet.
14 On the UDP2File application you should see the number in the packets field increasing
if there is any activity on the selected channel(s).
