How many addressable devices can an EST3 node support, and what cards provide the SLC loops?

An EST3 node supports up to 10 addressable device circuits per cabinet (Page 18) [4].

These signaling line circuits (SLC) are provided by the 3-SSDC1 Signature Driver Controller and the 3-AADC1 Analog Addressable Driver Controller modules (Page 18) [4].

Each Signature loop supports up to 125 detectors and 125 modules for a total of 250 devices per circuit (Page 337) [4].

Analog addressable loops support up to 99 detectors and 99 modules for a total of 198 devices per circuit (Page 337) [4].
