This building was cabled
with approximately 3000 outlets over five floors. Each floor had its own
telecommunications
closet which was linked
to the main comms room on the ground floor with 24 x Cat 5e backbones,
2 x 12 core
fibre backbones and 2 x
200 pair voice cables. The walls to enclose the telecommunications rooms
were built

This is David pulling in cables 24 at a time. As you can see the boxes are stacked up in 3 rows of 8 at the end of the runs and pulled back towards the area where the racks will be positioned. Once the main run has been laid the cables are split into bundles of 6 and fed out to each floor box in that area. |
| Here we have nearly 600 cables ready to terminate into the racks. The patch panels are 1u x 24 way so by pulling them in 24 at a time makes it easier to organize them ready for dressing into the racks. |

 |
This shows the area where the racks will be sited and you can see we have already started to put the bundles of 24 cables into 'socks'. Using socks makes it easier and quicker to dress the cables in but they also make it harder to add or replace cables. |
| This is another picture of the area where the racks will be positioned and it shows the main cable run leading up to the racks. At this point the cables are in 48's which then get split back to their 24's just before the racks. |

Here is a close up of the back of the racks showing the cables dressed up the sides and the sock trimmed to length. |
| This is the back of the racks. |

And here is the front of the racks ready to be enclosed in their own room and have the hubs installed. |
| This is the main comms room on the ground floor where all of the backbone cables terminate, it also houses the telephone switch and server racks. Some of the patching has been done. |
 |
 |
Here we see the same room with patching nearly completed. It is important to realize just how many patch cables will be required on an installation and make adequate provision for managing them. |
| This is part of a finished floor, it is the same sort of area that the picture of David was taken (top of the page) but on the floor below. Its hard to believe that this was such a mess only two weeks before. |

This is a different Dave and a different comms room! |
| Here are two Krone panels which have been prepared ready for terminating. |

| This picture shows the easy way to lay the pairs into the IDC blocks without over twisting or untwisting the pairs too much. |
 |
 |
The punch down tool should be kept at 90 degrees to the connection, this avoids splaying the IDC blades. (As the wire is pushed into the block the blades either side cut into the insulation and make contact with the core). |
