Boxes in GDK-100 system available. KD-Digital Phone Box is can be connected to the digital terminal
interface, and KD-ICM Box is can be connected to the electronic terminal interface (ETIB). But another GK or

terminals as shown in the figures 3.5.4.4.a and 3.5.4.4.b. When the wiring is complete, pull any slack wire
back through the base plate and push the housing back together.
