RE: Connecting WIC-1DSU? [7:61487]
I think the correct cabling is DESCRIPTION PIN # COLOR Receive from Network (ring) 1 Blue/White Receive from Network (tip) 2 White/Blue Transmit from Network (ring)4 Orange/White Transmit from Network (tip) 5 White/Orange so in this case should be 1-4 and 2-5.

You need to make a T1 cross-over cable. Pins 1,2 go to pins 4,5 and reverse. check the archives on groupstudy as this has been talked about indepth before. thanks, -Brad Ellis CCIE#5796 (RS / Security) Network Learning Inc [EMAIL PROTECTED] www.ccbootcamp.com (cisco training) Mike Mihalas wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

T-1 uses pins 12 and 45. Make a cable that crosses those two pairs. 1 to 4 2 to 5 4 to 1 5 to 2 If you don't have the tools to make a cable but do have two RJ-45 jacks - create the crossover between the jacks and use standard patch cables from the routers to the jacks. Yes, I know that a 110 punch down tool should be used with the jacks. Some small pliers, a small screwdriver and luck will also work for a lab - maybe not for a production network. -Original Message- From: Mike Mihalas [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 21, 2003 1:32 PM To: [EMAIL PROTECTED] Subject: Connecting WIC-1DSU?

Re: Connecting WIC-1DSU? [7:61487]
you need a T1 crossover cable...I have one in my lab for the same thing you are trying to do... it works great for simulation of two routers with DS-1 connections...

RE: Connecting WIC-1DSU? [7:61487]
yes you can do it. It uses pins 1,2 4,5.

Re: Connecting WIC-1DSU? [7:61487]
Absolutely. In fact I'm currently doing just that beta testing version 2 of the WIC-1DSU-T1. You need a T1 xover cable.

I'll see if I can dig up something official on the pins... Well I admit that I didn't search very hard, but I couldn't find a USOC website that wasn't affiliated with the olypics. USOC defines the RJ set of connector bodies. Looking at several vendor pages, it would appear as if the consensus is that: Tip = 2 Ring = 1 and Tip1 = 5 Ring1 = 4 Making it 1 to 4 and 2 to 5. That being the case, I stand corrected. But again, it doesn't matter. There's no such thing as a tip/ring reversal on a T1 (sending junior techs to troubleshoot such problems used to be somewhat of a right-of-passage in certain circles).

RE: Connecting WIC-1DSU? [7:61487]
You are correct. the 568A or B spec shows that pin 1 is tip and 2 is ring. Pin 4 is ring and pin 5 is tip for pair one. So for a tip to tip and ring to ring crossover then 2 to 4 and 1 to 5 is correct. -Original Message- From: s vermill [mailto:[EMAIL PROTECTED]] Also, it's interesting that most people say 1 to 4 and 2 to 5.

So for a tip to tip and ring to ring crossover then 2 to 4 and 1 to 5 is correct. Our copy of the 568 series TIA/EIA specs are out on a construction site at the moment. I'll be over there tomorrow so I'll take a look. You are exactly correct that the 568 series calls pin 1 a Tip, pin 2 a Ring, pin 5 a Tip, and pin 4 a Ring. So a 568 rollover is as you said. I don't know if the 568 series was ever intended to cover T1 though (it's common practice to use 568 patch cords for T1s these days, I'm just not clear that the spec was intended to encompass T1 stuff). I looked at ISOCs RJ-48C and RJ-48X, which apparently calls pin 1 a Ring, pin 2 a Tip, pin 4 a Ring, and pin 5 a Tip. The RJ spec is just a connector spec as far as I know. However, it was a connector spec geared specifically towards 1.544 T-carrier. Again, it doesn't matter technically, but it's nice to be precise wherever possible.
