Do the Digium cards have a built in CSU? Is a CSU an FCC requirement? or just a carrier requirement? TIA

Is there something special that needs to be done to allow a T100P/T400 to respond to a remote loop request? I am having some issues with a Point to point T1 line using zaptel ppp. This line gave us small problems when we had a pair of Cisco 2600's on either end but now with the zaptel ppp it is going down every couple of minutes for 15 intervals. The phone company says the line is good to

I've looked around briefly for what options are available for encrypting the media stream using asterisk. I did not see any SRTP support, and it looks like there is some initial work on iax2 encryption, but whether it works is still open for question I guess. I'm also curious of other solutions that could be bolted onto the front end of asterisk to provide encryption, and are there

Hi all, When configuring Asterisk with an ISDN card, it will at one point become necessary to select the LBO (Line Build-Out) value. This is an integer (0-7) that is determined by the length of the cable and is selected from the following table. Many of us are familiar with it: CSU (dB) DSX-1 (feet) ------------------------------- 0 0 0?133 1 133?266 2 266?399 3 399?533 4 533?655 5 -7.5 6 -15 7 -22.5 The value selected should almost always be zero. However, if t...

...f having 23 simultaneous conversations, plus you can do DID. One drawback is the inability to do a "Centrex transfer" (aka DID to DOD transfer or "off net transfer") but that usually isn't a big deal. One other note: in the US it is considered a legal requirement to have a CSU on any T1 circuit. However, it is not technically necessary. Also, some terminating equipment has the "CSU" built right in - e.g. Cisco T1/CSU WIC for their routers. I'm running 12 different T1 circuits, each with a CSU. I like having the CSU for testing and monitoring line condit...

Hello, I used a mac G5, R.2.1.1, and G77 3.4.4 and I would like to use and call a fortran subroutine. The trouble is that it seems I am not able to correctly load the compiled code. Here is what I have done: In the terminal this how I compiled my fortran code: R CMD SHLIB ~/Desktop/Fortan_kmeans/kmeans3.f There is the wrapper I have paste inside de kmeans3.f file: c

Thanks for providing the patch! I got around to testing it this morning and it appears it fixes compilation, but produces a non-working system. I know that's kinda vague and I'll have more details soon, including sample binaries. I at least wanted to give a status update so you didn't think you were being ignored. Thanks, -- Shawn Webb Cofounder and Security Engineer HardenedBSD
