A device needs to join a trust center using an install code. The link key used to join the network is
derived from the install code, which must be conveyed out of band to the trust center.
The joining node has an SH+SL of 0x0013A200 87654321.
The joining node has an I? value of 0x916720AC233734A86B809CC330B242EC23E and has DC set to 1;
this will cause KY to be ignored and use the install code to join.
