Terminating CAT5e and amphenol cable onto a CAT3 patch panel

By aw_willis ·
Hello everyone, I have 2 daunting issues and I seek for your support.
1. How do I terminate CAT5e cable onto a CAT3 patch panel.
2. What is the order pairing when terminating an amphenol cable that connects to an analog card (24port) of a Panasonic pabx unit.

I have tried a number of forums on the Internet but was unable to find solution to my problem.

Punch problems

1. You shouldn't be punching Cat5e onto a Cat3 Panel. I copper is totally different . I am not saying that it wouldn't work Cat 5 and Cat 3 are standards and you cannot interchange. I would buy a Cat 5 patch panel. However it depends on the wiring standard you are using. 90% of the systems I have seen are the 568B below are the wiring layouts your patch panel should have a paper or sticker on the punch side to tell you what order it goes it bases on A or B. But you must keep it the same this will determine your send and receive wires also you don't want to send voltage down the wrong wires you could possible **** a port if the device is sensitive.

EIA/TIA-568A:
Pin 1: White/Green
Pin 2: Green/White (or just plain Green)
Pin 3: White/Orange
Pin 4: Blue/White (or just plain Blue)
Pin 5: White/Blue
Pin 6: Orange/White (or just plain Orange)
Pin 7: White/Brown
Pin 8: Brown/White (or just plain Brown)

EIA/TIA-568B:

2. As for your Amphenol cable question they make Patch panels for Amphenol. So from your lets say pbx run patch cables to you Amphenol Patch panel that supports for two wire or 4 wire I would talk to sales rep. Or call Graybar.com they have the best support for this. Then run the Amphenol to a wall with 66 blocks and use cross connect wire to jump to end user wire runs. That wiring would be on the 66 block. If you use a patch panel two wire then the blue pair should be the 1st port...... so on you may not use the last port. I think the Panasonic use 4 wire though so blue and orange are your first extension on the patch panel that would be 1 then so on .......
