Trying to get a customer going and I've been out of the Nortel side of things for many years. Modular ICS system, maybe 10 years old, 6 of the M0X8AM expansion modules, two of them have no dial tone. Battery on the pairs, you can hear a relay clicking inside the module and the green light on...

I've missed the insanity, good to see that the discussions are still going! Often there is a clear desgined solution, and then several options for after the fact, retrofit installations. If you are stuck with one conduit, i'd stick with non conductive fiber and get AC power at the pole for the...

I know it's an old thread, but it baffles me that this still continues to come up AND be confusing to the professionals. First...while the interface can't tell color of jacket, be aware that there pairs are twisted at different rates, and at high speeds this can make a difference. For example...

brianinms, thanks, very helpful! I figured there had to be some instructions out there somewhere. Of course, having someone show you the technique and being able to see a job that was done right will help me. We do have a guy on site working for Verizon that is their expert. I offered a...

Thanks for your ideas folks, I do appreciate the links and suggestions. I've laced wires before, in bundles, but never 'sewn' cables to the rungs of the cable tray. A picture is of course worth a thousand words, i just can't seem to find a picture of this type of sewing. I'll keep looking...

Thanks Gentlemen, I'll need to edit my profile i guess. Former company went away two weeks before Chrstmas, so i have a couple weeks off but then back to work, more money better terms. Anyway, here is where i am. The horizontal cabling section of this job required an RCDD on site to oversee...

Greetings, I find myself in uncharted territory. I'm normally on the consumer side of things, but this month I'm inside a verizon wireless switching center doing voice and data cabling. After two weeks of debate and research, we're finally understanding the differences. The 'engineer' wrote...

Perhaps it is just more design driven, but a protective raceway for the fiber is a common and practical method of protection, plus it allows for very easy upgrades (62.5 to 50 micron fiber for example). Having watched other trades and building plumbing/steam pipe failures, having the...

Actually, the reason for putting the fiber in a raceway in a horizontal run is generally protection from physical damage. Plenum rated fiber will not provide any greater protection from physical damage than PVC jacketed fiber. Furthermore, there is no reason to spend the extra money for plenum...

I've never seen a row of J hooks exposed in an office, i suppose that is one way to accomplish it, but i wouldn't consider that a finish installation. If it must be exposed, I have used surface raceway (wiremold, panduit, etc.) or if the customer wants to actually see the wiring, a cable tray...

If you are going to use Pre-term you should run it in duct or conduit always Perhaps we are not clear on the definition of preterminated, but neither the type of termination nor the time of termination should dictate whether the fiber is enclosed in a raceway. You can order duplex 3mm fiber...

Wow, Sprint actually said they would charge to ID the lines? Those guys are a challenge. I've fought it with the many times. My favorite was a call to them asking for the binding post for a simple modem line that they delivered and didn't tag. I was informed that they could not give out that...

Sorry skip555 but all cat5 is 4pair, it's part of the specification of cat5 Belden made a media twist cable, 6 pair, category 5. I've got several rolls still. Also, I have 25 pair category 5 power sum cable. 25 pairs, category 5 rated. Daron J. Wilson, RCDD Solving 'Real World' problems

Wow we were poking at RCDD's and i missed my opportunity! As Nixon said, "Let me say this about that". First, I agree. Engineers/consultant with no practical experience are dangerous. Likewise, installers/cable pullers with no design/standards or networking savvy are dangerous as well...

At a typical cutover, a lot of people would be standing around looking worried, smoking cigarettes, drinking coffee and making periodic forays out of the telephone equipment room to reassure the customer:"Yes, at any moment now you will be back in business" Pretty good summary. In short, i...

Well yes, but only for DC continuity. A very nice piece of cable at DC could be pretty much useless at 5 Ghz. I personallly do a DC continutiy check on every patch cable i make if i have both ends available, just to make sure I have continuity and no short. For HF and VHF stuff it's not such...

Very sound advice. One thing that i see a bit frustrating (though comforting to us old guys with experience) is the desire to have a 'go/no-go' test for things. In fiber, most of my guys just want to push a button and see if it passes. I personally prefer to look at the OTDR shot as well...

Buttons don't just disappear when you unplug a phone. Make sure it is the extension they think it is. Well I do understand your position, the manager has one phone in her office, she said this happened before when she unplugged it and moved it to the conference room, then moved it back AND that...

IF you are in fact only needing Xon/Xoff, then you don't need the hardware flow control or loopback pins at all. However, I understood your post to say that you were using software flow control but did not have connectivity (i.e. something on the hardware side might be holding you up). RS-232...

Thanks, I hate it when customers do this to me, sorry, but let me share a bit more. It apparently happened when she unplugged this set and took it in the conference room to use it as a speakerphone. She then returned to her office, plugged it in, and then it wouldn't ring on incoming calls...
