Installation Overview The following steps provide an overview of the installation process. Details on each of these steps are contained in the following sections of this chapter. Be sure to read the detailed instructions before installing the DX-80. 1. Plan the installation, including the KSU1 or KSU1 and KSU2 and Main Distribution Frame (MDF) location, station locations, cable runs, and optional equipment. 2. Assemble the correct tools and supplies: UTP telephony grade cable/wiring, miscellaneous telephony hardware, 66 blocks, modular wall jacks, etc.) 3. Run the wiring for speakerphones, DSS consoles and analog devices (FAX machines, modems, etc.) from the MDF to each location. Wiring topology is referred to as “star-wiring” configuration; no cable should loop from one telephone location to another. 4. Run cable/wiring to any optional equipment, such as external paging equipment, loud bell signaling devices, music sources, etc. 5. Mount the MDF backboard and attach the terminal blocks on the backboard. Use a dedicated MDF with 66 block wiring field to promote full serviceability of the system and connections using proven techniques. If you route extension cables into the KSU, you have to terminate one cable pair into standard crimping modular connectors for each cable.
