I think it is correct. Isn't that why they call it a Smart Jack? I've only ever seen a regular cat5 cable used from the Smart Jack to the device (router/PBX/CSU/DSU/whatever). I believe the point of the smart jack is, amongst other things, to allow for the use of readily available cables. I agree however that back-to back (PBX-PBX etc) you would need a cross-over cable.

(Let's see how many can figure out how to do that via an rj45 plug. ;) You use shielded plugs and jacks, of course :-) That is why the TE405P/TE410P have shielded jacks (as of about a year ago, IIRC). The retail packaged cards even ship with four shielded cables included! Minor point: isn't it safer to only ground the shield on one end? ___ If you want to fry your cards attach both sides to ground, I don't know about the engineering specs but 'floating' one side has always eliminated ground-loops, and the possibility of lightning damaging the cards. As a rule I always ground the side furthest from my equipment as I want the lightning to go that-a-way!!! Electricity is lazy by nature and always tries to find the shortest (least resistive) path to ground.

I for one think it is a great idea to buy a book with hard earned money and wait a few days to a week just to get an answer to a question that is freely available on the internet immediately. Hard pressed to think of anything in the book that is not on with wiki with more up to date and useful information. -Original Message- From: Alexander Lopez [mailto:[EMAIL PROTECTED] Sent: Sat 4/22/2006 11:59 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Cc: Subject:Pinouts for T1/E1 crossover cable WAS RE: [Asterisk-Users] whatcable to connect a legacy PBX to a TE410P ?

A T carrier cable is not the same as an ethernet cable. A T carrier cable uses a real metal shielded RJ-45 and loosely twisted pair wire. With most modern T carrier equipment, you can use a CAT-5 ethernet cable instead of a real T carrier cable. A T-carrier crossover cable does not have the same wiring pattern as a crossover ethernet cable. With an older piece of equipment like the Matra, I would be tempted to purchase a real T carrier crossover cable. This is covered in my book, by the way.

I agree. I haven't had a problem using CAT-5, even for long runs, however it's not a real T-Carrier cable and I didn't know how old the PBX is.

I have used cross-connect wire from the spool to make T1 crossover cables with RJ45 ends. All that matters is that pin one goes to four and two goes to five on both ends.
