Cabling: The Basic Foundations

The days of telephones and computers and other IT devices being wired separately
on two different standards (telephones CW1308 and computers CAT 5e or higher) should have long gone!

Ideally all business's should have a form of ‘structured cabling’ (CAT 5e or higher) distributed from a central Comms Cabinet, as all new equipment requiring a telephony or networked connection(s) now have standardised RJ 45 plugs requiring RJ 45 outlets

Structured cabling provides these outlets therefore allows for a "plug and play" installation of devices
Telephone, PC, Printer, Card-machines, Franking machines etc. in fact any device requiring a telephony, network and or internet connection.

This in turn should help reduce installation costs of new equipment as the supplier knows the connections are to a standard so reducing engineering time.

On this point we always say you can’t have enough RJ45 outlets, we also recommend a minimum of two outlets per socket point. Very seldom do we install just one outlet as the labour to install an additional cable at the same time is negligible compared to installation it again at a later date.

We we explain in more detail how structured cabling works from a user point of view in the next post.
We will also go into more detail the different standards and why test and certification is important.

We can install, test and certify new structured cabling, or tidy existing installations
Below are some examples of cabling we have been asked to ‘tidy up’.


We always advise on installing a Comms Cabinet big enough for expansion.
Our saying is “You will always fill it”.

We swapped this over one evening so the business was not disrupted. Much tidier now!

IT Cabling Tidy Up

It’s not ideal having IT kit on the floor! We can offer a stop gap solution whereby we keep the existing cable and re-terminate existing cables onto new patch panel(s) and allow equipment to be installed off the floor. This saves on total re-cabling. We used a metal framed bracket for this job as opposed to a full sized cabinet as there was not enough room.
Note: electrician installed 240v sockets after we left and tidied the job further.

An historic installation of cabling in the under stairs cupboard. Again a metal framed cabinet was used and there wasn’t enough space for a full sized cabinet.
Note: the BT ISDN lines were relocated and the green cables tidied after this photo was taken

IT Cabling Messy
Basic Cabling Improvement

Example of bad planning by the landlord and original cabling contractor from day one
There is not enough room in a broom cupboard for IT and Telephony equipment!

All we could do here was install a new patch panel for the analogue phone system
Label and test all the sockets, then re-patch with coloured patch leads, Blue Telephones, Yellow Data

An old school business that asked us if we could tidy things up.
We did and the customer was pleased with the results.
Not ideal but a lot better than it was!
