you can either terminate them all on a data block/ patch panel and extend them with patch cords. or crimp rj45 ends and use a thru connector. splicing buttons will work but so will barb wire, it just depends on what you want.

The cat-5 cable is electrically a transmission line. A transmission line has a property called the characteristic impedance, which is a ratio of the Inductance and Capacitance, both of which are a function of cable geometry. A transmission line also has resistance, which affects the signal and its propagation.
As a signal travels down a transmission line, it continues to degrade in amplitude as well as rotate in phase. When the signal hits a change in impedance, part of the wave is passed through and part of it is reflected back. The amount that is passed versus rejected is determined by the mismatch in impedance from the cable. The reflected signal can interfere with the other signal data traveling down the line. In an ideal sense, a perfectly terminated line will deliver maximum signal into the load and reflect no signal back. A significant enough mismatch or a high enough resistance can also degrade the signal amplitude sufficiently to render it unrecoverable at the receiver.
With a splice you potentially introduce an impedance mismatch, which you want to avoid. The effective overall data rate will be impacted by the signal quality. Hence, it is possible that your splice will effect your speed. However, with most digital transmission, there is a point at which if the signal is "good enough" you will maintain maximum speed and avoid any data loss. This is an example of why things like heavy gold plated cables for your digital TV signals don't necessarilly buy you any improvement.

Mounatain bear is nearly correct. There is one better option.
Ideally you want to use 110 blocks to make the "splice" just as you would where Horizontal meets Vertical elements.
Next comes the plugs and through adaptor (all Cat5e of course and
Lastly a connector block with patch cables (since proper stranded patch cables are NOT as good as solid installation cable).

So do not use a 66 block to seperate the pairs?
For example if I have to use a portion of the pair for voice and the other for voice then could I frst punch it down an the 66 block then lests say use the BLUE and BROWN pair for voice and the ORANGE and GREEN for data?

IIRC 110 blocks are Cat.5e rates. I know that 66 blocks are not.
As far as splitting out pairs, I don't see the relevance to this thread. ?

Splitting out pairs for voice or data for sharing in the fashion you mentioned above is does not adhere to the standard, and causes all the impedance problems mentioned by Norway2. If you want to do that, run a separate cable for data and a separate one for voice. Otherwise, use modular adapters or octopus cables @ the jacks and patch panels to to get the pairs you need without bastardizing the TIA 568 standard.

What is there is no alternative and there is only one single 4 pair run available. Sometines two runs for voice and data are just not an option for some customers.
Also some customers are not speed freaks and as long as the PC work station is operating and the speed is acceptable then there may be a decrease in speed but it might not cause a problem for low use PC applications.

Syquest has the answer for situations where running another cable isn't an option:

We have Cat5 joiners here in Australia. A company called RS Components sell them and I think they are a Global company.
See Here....
They also do one for STP

I have also seen Krone Hi band used where multiple cables had to be extended.
(sorry different country what's a 66 style block)?
