I'm currently using RJ48C cables to connect an aculab card (Prosody PCI) to a PBX to make calls, etc. via this. Unfortunately I've had several problems with this, as the setup seems very fragile with regards to physical strees as minor pushes, shortcircuiting cables, etc has caused quite a lot of havoc. I was wondering whether there was anything to do about this, and have a few questions1) The wikipedia page mentions that
"RJ48X is a variation of RJ48C that contains shorting blocks in the jack so that a loopback is created for troubleshooting when unplugged by connecting pins 1 and 4, and 2 and 5."
Would a RJ48X cable give earlier/more distinct warnings when state was inspected through appropriate software (aculab callmanager)?2) Is there a variation of Cat 5 cabling/RJ45 connectors that makes it easier to fabricate the cables?
3) Where to buy the cables? A google search only turns up one company in the U.S. Is the standard known by some other name in Europe? Or does everyone make these cables themselves?
I'm amazed at how easy the setup breaks (say compated to standard ethernet), so in general I'm wondering how other people handle this?
