Still here...

So my ISP,, had it out with Verizon, the DSL backbone provider, over the past couple of days.  According to Avvanta, Verizon had a faulty DS3 card that needed replacement.

So I'm wondering what is a DS3 card?   So I popped the term into Live Search and found the Cisco documentation on replacing a DS3 I/O card.  The following figure is a what a DS3 I/O card looks like:

I should say that I'm no network engineer, so please do not take the information here as being completely accurate. 

But if my research is accurate, oh the irony that a little 12 cm piece of fiberglass and resin would bring the network to its knees. Laughing
