If you mean the typical premise cabling and jacks for data comunication networks (Cat 5, 5e, or 6 UTP and RJ45 jacks) here are a few links.

Derater,

The term NJPJ must be directing towards "Network Jacks / Phone Jacks".

Most commonly, the LAN will be an Ethernet based LAN with a speed of 100 MBPS.

Currently, the most common design would use 4 pair CAT-5 UTP for "Data" and 4 pair CAT-3 UTP for "Voice" and "Analog [MODEM]".

The entire design topology [AKA LAN Map] will need to be reviewed if you plan to pull cables and terminate.
Ask the Client to request a meeting with their Network Administrator or designer [AKA the Netgeek or "Ol' Dorito Breath"] to discuss specs and locations for equipment and outlets.

There are several types of cable specs used, so find out which one is required.
For UTP, the most basic for anything above 10 MBPS is plain CAT-5. Above this is CAT-5e [and other varieties of enhanced cables], then CAT-6.

After you get more info from the client, please post more to this thread so we can help make sense of things [plus add some suggestions].

Good luck!

Scott. S.E.T.

Rather than install cat3 for voice and cat5 for data you can install a cable solution that accomplishes both. One jack (rj45) does both data and voice.

Will you be warrantying the cable plant?

Are you certified for any particular cable solution?

The last fiber plant I installed was guaranteed by the manufacturer (siecor) for 15 years if installed by a siecor certified installer (me).
