The RCO pinout towards the backplane is different on the ASLT and the ATLB.
This is not a problem when using AlphaCom E20/E26, because the ATLB connection board and the RJ45 filter board is adjusted accordingly, so the RCO's comes out correctly.
But in the AlphaCom E7 there is a direct connection from board pos. 1 and 2 to the RCO 1-6 and 7-12, designed for the ASLT card pinout.
When using ATLB in AlphaCom E7 only four RCO's are available, and they come out on different pins than what you expect:
- Logical RCO 1 (65/1) is not available
- Logical RCO 2 (65/2) is not available
- Logical RCO 3 (65/3) triggers physical RCO 2
- Logical RCO 4 (65/4) triggers physical RCO 3
- Logical RCO 5 (65/5) triggers physical RCO 4
- Logical RCO 6 (65/6) triggers physical RCO 5
