Thanks, Steve Totaro ___ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users Steve, what is the proper grounding procedure and what does good grounding achieve? In this instance we are in an office tower and have 13 POTS lines. There is a good ground hanging off the wall from the legacy system but what do I connect it to? Is a surge/lightning protector product required or is there something more rudimentary can be done? The concern here is more with call quality than lightning/surge protection. regards, Drew -- Drew Gibson Systems Administrator OANDA Corporation www.oanda.com ___ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

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.

Re: [asterisk-users] Heavy duty environment - Is TDM2400P suits?
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. http://www.twacomm.com/catalog/dept_id_602.htm I usually use Graybar.
