USB - USBF TV

Description

USB Field allows you to use a standard USB 2.0 connection in harsh environments

• Sealed against fluids and dusts (IP67)
• Shock, Vibration and Traction resistant
• No cabling operation in field and no tools required
• Mechanical Coding / Polarization (2 positions)
• Improved EMI protection

With USB Field, you can insert a standard USB 2.0 cordsetinto a metallic plug which will protect it from shocks, dust andfluids.No hazardous in-field cabling and grounding!

This metallic plug is connected into a receptacle, using a Tri Start Thread coupling mechanism (MIL-DTL-38999 series III type) with anti-decoupling device for high vibrations. On the receptacle side, one A USB receptacle is soldered onto a PCB allowing for the following back terminations:

• another USB-A receptacle
• solder : 4 tined holes on the PCB to solder your wires

The USB 2.0 cordset shielding is transmitted to the USB receptacle through grounding fingers. For an outstanding EMI protection, the conductive plated shells (Ni, Cd) with metallized receptacle inserts, transmit the shielding to the connector shells and finally to the panel.

Asterisk - WANPIPE® Echo Spike Generation: Debugging (Linux)

When a system suffers from an intractable echo, it is often very difficult to diagnose the origins and possible solutions to the echo problem. WANPIPE^® has a utility that allows the echo from a unit impulse to be examined and analyzed.

Important:
If you have Sangoma Card with Hardware echo canceller, the echo spike is not very important or useful.
In this case we suggest using hardware echo canceller tools to determine the echo problem:

To debug Echo problem during the phone call:

1. Install WANPIPE version beta1w-2.3.4 or later, use the following command when installing:

./Setup install --echo-debug

The Setup script will patch Zaptel driver, so it will have to be recompiled/reinstalled after WANPIPE installation is complete. Software Echo canceller should be enabled on the span, where the test will be done (or on all spans).

2. Make the phone call and check if there is echo.

Find a number that shows consistent echo for this test. The test should be done from the side where the echo is heard. Ideally, mute the phone on the remote side during the test. Note the Zap channel number on which the test call is done, for example channel 12. The rest of this document assumes the test call is active on Zap channel 12.

3. Run the following command:

#>wanpipemon -zap -c ses -zapchan 12

A test impulse is sent on zap channel 12. The Finite Impulse Response (FIR) is saved to the file: /etc/wanpipe/span_1_chan_12_before_ec.spike as a set of linear samples taken 8000 times per second.

4. Copy the data from /etc/wanpipe/span_1_chan_12_before_ec.spike into a spreadsheet.
