[Asterisk-Dev] OT possible idea for alternative uses ofDigiumT1 Hardware

Mon Oct 11 09:17:21 MST 2004

OK so we all think its cool!! The more I think about it a USB device with 2 T1/E1, 2 BRU, and 1FXO and 1 FXO would rock it would be able to connect into a tablet, PC, laptop, a small VIA based box. 

I know to code for USB exist at a limter level for FXS would it be hard to throw all of the above on the USB bus. 

2.0 should have the bandwidth available to do this. 

I always knew that Asterisk would change the world, however, I am still amazed at how far the change can go.....

If you're going to go with a laptop, there are several ruggedized  
varieties that have full sized PCI expandibility.

See the Power-Lite on  
http://www.pep.com/various/flyer_PUSH_Revolution/

I was thinking more along the lines of a pen-based tablet.

A zaptel pcmcia device would definitely need to be a cardbus version,  
as I don't think regular 16-bit pcmcia would have the bus bandwidth  
necessary.

The whole thing would be extremely cool, though.  It wouldn't just be a  
T1 test set, though.  It would be a T1 test set, ISDN analyzer, HDLC  
analyzer, Frame relay tester.

You could also stuff either a TE4XX or 2 T100Ps into your unit and do  
pass-through analysis.
