No, I have only heard of Vantage 12 & 48. I didn't know that there was an 8 & 24 as well. I can't recall now what the cabinet looked like for the Vantage 48 either.

Such an interesting or maybe unusual design to have each card in the system support two stations and one CO line.

I might have to dig out the Vantage and power it up again soon!


Oh, that was just one type of card it could accept.

The Vantage 48 could accept a 4 CO line card (4x0), a 4 station line card (0x4), and a 1x2 as you describe (1 CO, 2 station).
There were also group switch configurations which had to be sequenced with the next three adjacent cards -- which could be two 1x2s and one 0x4, or one 4x0 and two 0x4s, or one 1x2 and 2 0x4s, or a 4x0 followed by a 1x2 followed by a 0x4.

How's that for strange.  Those were the only legal sequencing combinations under that config.
