Creating a 24-port Patch Pannel to 5 x 10 wire Krone Punch Blocks
These are primarily used to patch E1 lines into access servers. The Krone Punch Blocks are used to interface between the telecomunications equiptment and your patch pannel. The below instructions were written to create a patch between Telstra OnRamp E1's and our Racks to feed our Dial-up lines into the Access Servers.

Required equipment:

10m (or whatever) 50pair communications cable, or similar.
1 x 24 port krone RJ45-F patch panel.
5 x 10 pair krone punch block.
Cable Ties (Assorted colors if you want to make it easy to track bunches of cables down).

Apropriate tools, krone tool, side cutters etc...

The cable:

Be sure to measure out the length of cable you need first, giving yourself at least half a meter or more to play with just incase there are corners you didn't account for during measuring. Don't forget it is easier to cut cable off then to streatch a short run.

This cable is divided up into 50 unique pairs, based on solid colours, matched with another solid colour with or without additional stripes of paint to identify them with. This document is one method using one of these cables to connect a 24 port patch panel to a krone punch block.

Although this cable is not usually rated for cat-5 use, it is perfectly suitable for 2meg e1's, (but we have used it in some places for short runs of 100meg ethernet without any problems.. this document does not explain how to make an ethernet patch).

The patch panel:

This is made up of 24 individual female RJ-45 sockets mounted on a 1RU bracket, there is a 4 pair krone punch block on the back of each socket.

Each of these blocks has a small diagram showing how you would connect 4 pair cat-5 cable to the socket. There will sometimes be two diagrams side by side, one labeled A the other B, the B diagram refers to the pairs you would use if you were making a "cross over" ethernet cable. For the purposes of this document we are only interested in the first diagram.

Which looks a little SOMETHING like this.
 
              |---|---| 
  Brown/White |=7=| 2 | Green 
              |---|---| 
        Brown | 8 |=1=| Green/White 
              |---|---| 
       Orange | 6 |=3=| Orange/White 
              |---|---| 
         Blue | 4 |=5=| Blue/White 
              |---|---| 
                  A
To connect an E1 over RJ-45, the transmit and receive pairs go on what is seen as the Green/White + Green and Blue/White + Blue pairs were you using 4 pair cat-5 to connect to the socket, to reduce confusion with the rainbow of coloured pairs refered to later in this document we will from now on call these, 1/2 and 5/4 (These numbers refer to the pins on the RJ45 plug itself).

The Krone Punch Block:

This is a 10 pair block with 10 pairs of Krone style contacts along the top and bottom of each block. It looks a little like this.
 | |==][ ][ ][ ][ ][ ][ ][ ][K][R][O][N][E][ ][ ][ ][ ][ ][ ][ ][==| | 
= == == == == == == == == == == == == == == == == == == =  
 | |==][1][ ][2][ ][3][ ][4][ ][5][ ][6][ ][7][ ][8][ ][9][ ][0][==|
The pairs coming from the patch panel will be punched into the top row of contacts, the links to the telstra punch blocks will connected to the bottom row.

As you stack 5 of these blocks together to make up the 50 pairs needed for the patch panel, the bottom one is the lowest number, and the top one is highest, we will refer to these 5 blocks as blocks 0,10,20,30,40. (This ties in with the numbering standard used for documenting large punch block frames).

Finally - What pairs go where on the patch panel end.


The following notation is used for specifying a pair of cables. colour/colour or colour/colour+paint

eg. a pair with one white wire twisted with a blue wire "white/blue". a pair one yellow wire twisted with a green wire with blue paint striped on it would be "yellow/green+blue".

The first wire will be either white, yellow or black. The second wire will be either green, blue, orange, brown or grey or white. possibly with green, blue, orange, brown or grey paint.

For every pair with a white wire, there was an identical pair with a yellow wire, we figured this could take care of most of the ports on the patch panel in a logical manner.

Here is a table, it's probably not industry standard if there is such a thing.

If the colours in your bundle of cable to not match those listed here or you are using more than one smaller bundle, then substitute apropriately.

Good luck, and try not to stab yourself in the hand when putting floor tiles back down.

Thanks to Morgan Look for doccumenting this one :)
