How many boxes (PIMs) does your system consist of? This will tell us whether you can expand the system or not in legacy equipment. Do not count the boxes that only contain batteries. if the answer is 8 then your vendor is possibly correct.
If your system is an IVS2 or IPS then eight circuits per card is the norm however some cards can have only 4 circuits. the question of how many cards per box depends on the system type and also can depend on the type of cards fitted. For example an IP Pad card is only one card but takes up 30 time slots so effectively half a PIM. Cards in the system are dedicated not hybrid so a digital card will only drive Dterms and an analogue card will only drive analogues.
The easiest way to swap extensions is at the punch down blocks.
No the punch down blocks are more like a patch panel. The pabx is a switch
