Next I needed to know how many phone lines there were in the office that handled law enforcement calls, and the phone number for each line. I had found out that the State of California used a telephone switch from Northern Telecom, the DMS-100. I called the State of California Telecommunications Department and said I needed to talk to a technician who worked with the DMS-100 switch. The technician I was transferred to accepted my claim that I was with Northern Telecom’s Technical Assistance Support Center, in Dallas, so I launched into my spiel: "In the current release of the software, we have an intermittent issue where calls get routed to the wrong number. We’ve come up with a patch—it’s a small fix, and you won’t have any problems with it. But in our customer support database, I can’t find the dial-up number to your switch."
