UCM Communication-Link

Communication Links
Unit control module (UCM) communication links are used to connect
UCMs to the BCU. Each BCU has four communication card slots and can
have up to four UCM communication links. You can configure each link
with any one of the five types of UCM communication cards.
The types and quantities of UCMs that you can link to standard capacity
and high capacity BCUs are shown in Table 7 on page 46. BCU capacity
is determined by whether just the standard capacity module is installed
or both the standard and high capacity modules are installed in a BCU.
