If you really need the job and you can get into the tel-com program, I'd say go for it. I've heard of people in my local (375 Allentown, PA) who have started with tel-com and switched to Inside Wireman later when there were openings. The Inside Wireman(journeyman) has a higher wage than the tel-com. Although the 2 fields are different, you'll use a lot of the same skills in both.
