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 questions
1) The wikipedia page mentions
"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?
