Table 3-1 summarizes the external connectors and identifies the chapter sections that provide
more detailed information. The rear panel connectors are typical for both the MBT-5003-XUR
Up Converter and MBT-5003-XDR Down Converter units. Front panel connectors, if not typical,
are identified as unique to either unit, both in the table as well as chapter sections that follow.
