NTT engineer in the wings?

Hi Baldur, Based on the information you provided, CPE connects to the POI via different service provider (access network provider / middle man) before it reaches your network/POP. With this construct, you are typically responsible for IP allocation and session authentication via DHCP (option

I was going to say... in my experience (I've been to a lot of the Arizona electronics sites, having grown up around broadcasting) that most of the microwave equipment in use was for Bell. That was by far the most populous tower on any mountain top. The broadcasters don't send their signals
