What? A TD-1232 is two cabinets of 8x16 and an additional 16 extensions per cabinet. That's how the base unit has a capacity of 12x32 with full cards, but it can address 12x64 extensions either 32 or 64 digital phones (with exceptions) or 32 digital and 32 analog phones. With a dual cabinet system, you could get towards 128 digital phones.
As far as trunking, you can have 24 analog trunks or 32 trunks with 24 T and 8 analog.
