Flourescent light and intermittant ping 56k frame relay

[robsuttonjr]

I was working on a problem with our frame relay connection today. Our ping rate has been intermittant say 6-10 misses out of a 100. Our previous network guy is gone so I inherited the situation and I have been on-call. So I was tired of getting called about the connection to our credit card company going down. Anyway I repunched the patch cable to the dmark directly, remade the RJ45 end going into the 56k card of the router, and moved the wire so it was not running directly over a flourescent light. My question is which was the likely suspect? Could having the cat5 solid gauge wire over the flourescent light have caused the intermittant connection drop?

The more I learn the more I find I know nothing.

i doubt the flourescent light will have a lot to do with this....but there could be a possibility....have you check your FRAD/modem?

SET CRTL ALT DEL = #728

After doing the 3 things, moving the cable from over the light, redoing rj45, and punching cable directly to provider dmark the intermittant drop is gone. I guess it doesn't matter really.

It has been my experience that the physical connectivity is usually the culprit. You could have had an iffy connection to the demarcation point, or faulty connector. One thing I have found on “home made” cables, is that sometimes people mix up their connectors in their case, and inadvertently put a stranded wire 8 pin modular connector on solid wire. This will most definitely give intermittent connectivity

During seasonal changes I keep an RJ45 crimper on me. I find crystals go and get iffy during these times.

Why is there never a phone in the phone closet?

The answer seemed to be the iffy connector / dmark punch down. Seems to be a punch, test, and repunch as needed type technology. I imagine there is some sort of equipment we cannot afford that would tell us about noise on the line. The simple approach in this case was to repunch/recrimp until problem went away. Works sold now.

Forums rule, pass it on!!!

Light ? No, 60hz is very unlikely.

Getting Tired of phone calls for service ?

Test and Scan your work.

What stands out is the way you described how it was done originally-

somethings, even though they can be done, don't.

The connector was likely loose or not properly seating in the jack. Direct termination to the demarc resolved your issue, thus your answer. Use matched jacks with matched ends (connectors)...even though it works doesn't mean it will work all the time.

BTW- Cat5 is NOT solid, it's twisted

The older I get, the less I know
