asterisk users - Aug 2007 - Heavy duty environment - Is TDM2400P suits?

Hi all,
I am planning to have a new TDM2400P to replace all Planet 450 SIP
gateways. Can TDM2400P survive in heavy duty environment where there
will be >4 concurrent calls in within the same second? Thanks!

Yours sincerely,
Jason Chan

I am using TDM2400 with FXO modules to handle 16 concurrent calls to PSTN
for more than 12 hours a day with no problem at all.

You should have no problems.  Make sure you put surge protection and 
ground your POTS lines.  It is a small investment.  I have had SEVERAL 
FXO modules die or behave strangely after thunderstorms.  I cannot prove 
it was a surge, but logic would indicate that was the issue.

Thanks,

Steve,
How are you providing surge protection? I have lost a couple of cards to
storms also.

Here is a good read as far as what your risk is and how to mitigate it. 
They clamp on top of your terminated 66 blocks and you also want to 
properly ground.

Here is a vendor with a good selection and pricing. I have no idea if 
they are any good, I have never used them.

I usually use Graybar.

Thanks,

I am wondering, did you try to RMA these modules? How did Digium handle it?
