For those who care about these things....
Verint installed their cabinets, OCS provided and installed the cables to the backboard. Cables are standard 25 pair raw end to a 50-pin Amp. The VAM here in Torrance is bridging accross ISDN 4w ST interfaces; there are 8 circuits per cable. 2W modules run 16 circuits per cable.
On the Backboard the Cables from the VAM are terminated normally, which leaves the last 9 pairs useless. But I do not split small cables across blocks.
My cables bridging the ISDN are 12 circuits per cable, terminating one cable per block also. 4w cross connects.
