I'd like to return to the 415 card, the hot line or tie line or automatic ringdown, etc. I have read the BSP and you are correct whoever said you need another 415 card at the far end according to BSP. However, that seems crazy to me. Does that mean you have another KSU with a 415 card there or is the card mounted by the other phone's jack? It does not make sense to me. I have an automatic ringdown unit, not a 1A2 system, that you plug one phone in one jack and the other phone in the other jack. It seems to me that if you had a 415 card in slot 4, when you pressed line 4, some designated phone would ring. What am I missing here?
