3 | The smallest functional TCSM2 system consists of one TC1C chassis and one ET1TC chassis; each chassis has its own backplane. A set of signals needs to be interconnected between the TRCO card in the TC1C chassis and the [[TCSM2_ET_modules|ET module]] in the ET1TC chassis - hence a special cable is needed that connects the two backplanes. On the back of each chassis there is a DIN 41612 connector (size C, 96 pins total) with male pins - the interchassis cable attaches to these two connectors, S00 on TC1C side and V00 on ET1TC side. |

5 | In a large system, each ET1TC chassis supports two TC1C chassis, hence whatever official cables Nokia once had (we haven't seen them) must have had a complex structure, with one half of V00 connector on ET1TC connected to one TC1C chassis and the other half connected to a different TC1C. However, if a hacker is putting together a minimal TCSM2 system in her lab and doesn't have Nokia's official cable, a simpler cable will need to be hand-crafted that connects the single TC1C to the single ET1TC. |

7 | Because the male DIN 41612 connectors on the exterior back faces of TC1C and ET1TC backplanes are of "full C" size, as opposed to "1/2 C" DIN 41612 connector on [[TCSM2_ET_modules|ET2E]], the availability of mating connector parts (female DIN 41612, free-hanging inline for mounting on cables) is a little better: several options are available from Digi-Key _without_ cost-prohibitive MOQ. For our setup in Themyscira lab, we are currently attempting to use "Harting 09032966823":https://www.digikey.com/en/products/detail/harting/09032966823/3179778 for the connector body and "Harting 09030960501":https://www.digikey.com/en/products/detail/harting/09030960501/3179722 for the shell housing. The parts are currently in shipping transit, hence no actual fit test has been performed yet. |
