Hope that this shows up clear. Assuming
Matrix. <-- SIN xxxx --> Decker cyberlink+cyberdeck
Decker <-- slave --> Street Sam 1 commlink
-- Street sam 1 commlink <-- slave --> SS1 commlink 2&3
---- commlink 2 <-slave --> cyberware & devices upto device rating
---- commlink 3 <--slave --> cyberware & devices upto dr
Repeat per street sam.
Basically, the decker is a commlink operator for the link between team commlinks and matrix. Note the limit on 1 times device rating may mean decker needs to carry many commlinks to act as access points for slaving.
