I would have to disagree. Telecommunications is not going away, but it is changing.

If you're interested in a career in this field, look for a job with an interconnect, as was suggested. Also, learn as much as you can about networking via school and by practicing on your own.

Read whatever you can get your hands on about Telecommunications, both old-school and new.

Phones and cabling go hand-in-hand. Learn codes and standards. Consider some BICSI training. If you want to set yourself apart from 90% of the IT Guys and other cable installers, read/study the NEC.

Computer knowledge is a must. I guess that is true for most fields now.
