Hello All,
I am a network Technician who has worked for a university for the first 6 years of my carrer. The job is getting stale and my new boss seems to love herassing me about my militarty duty. It's time I leave. Anyway... I've spotted several jobs that describe exactly what I do however they add the Technician should have expirence in terminating and installing DS0 DS1 DS3 cables. Now I have seen these cable and know what each looks like. I'm not familiar with them beyond that. Could anyone provide me information about these cables and how/where they install? how do you trouble shoot these cables? anyh learning advice about these cables would be greatly appriciated. I went on an interview last week and I was asked "If somoene is haveing a connectivity issue and the cable is good from the RJ45 to the patch panel, what is the next thing to test, how do you test it?" Well I had a blank look on my face. Can anyone add some insight?

It sounds as if the interviewer was testing your familiarity with the seven layer OSI model. If you check the Physical layer first, then you want to move up through all seven layers to the application layer. But when I was a computer tech, I started at the Application layer and moved down to the Physical layer.

In all honesty, I may of had the same blank look though, since the question is a bit ambiguous.

DS1 cabling is typically just traditional twisted pair, CAT5 or better that terminates on an RJ48X jack. If a DS1 circuit is being extended from the telco demarc, traditional 568A or B wiring is fine. The key is that the jack on the customer end must contain shorting bars that keep the circuit alive when the terminal equipment is unplugged, though many people simply install a CAT5 cable that is terminated 568B on both ends.

DS0's are channels in a DS1, and a DS1 contains 24 DS0's, each at 64k. DS1 is commonly referred to as a T1. There really isn't any wiring for an individual DS0 (channel).

DS3 cabling involves dual (transmit/receive) coax runs, RG59 for short lengths or 734A for longer runs. The cables are terminated using male BNC connectors.
