I was so excited about installing an ISDN line for my customer that I never realised I have overlooked some minor details. Prior to the installation, I have been running the "simulation" in my mind over and over again. And so, on that day, I was ready for the word, "Go".
Last week, my technicians have laid the necessary cabling and this week, it will be my turn. The ISDN interface card is ready and so is everything. We convinced them to go for ISDN because their normal analogue DID lines are always giving problems where power surge or lightning storms are concerned. Imagine the delay when we need to take the cards back for repair and so on.
