It all depends on what 308 you inherited. The basic system is capable of 3 lines and 8 digital phones with the first 4 ports being "combo" ports. The 30891? card gave it 8 combo ports and DISA or something like that. (I don't remember, that's what they make manuals for)
In your study, you will learn what a 6-pin jack is. It has the capability of being used for 1,2 or 3 lines, all counting from the center pins. A 4-pin jack, clearly misses the 3rd line that would be in the outer pair. You can find and crimp 6-pin plugs and associated jacks at any home improvement store.
The manual also shows how Panasonic uses a 25-pair cable. It's always in 3-pair configuration, with the first pair for analog, the second pair digital, and the 3rd pair for whisper page on the proper phone. Panasonic has both analog and digital proprietary phones, the analogs use 2 pairs. Again, it's referenced in the manual.
It may show the color code, but if it isn't just search 25-pair color code for telephone cables and you'll get several hits.
And last, check your PM's. There's a link to the 308 manual there.
