1.2 CC1 CONNECTION GROUPS
The rear view of a matrix switch (referenced in the block diagram of Figure 1-1) is shown in
Figure 1-2. Outputs destined for HS connections can be categorized, corresponding to the designated
functions of the subunits to which they are attached on the hot switch. For discussion purposes, these
outputs are partitioned into three groups: the Control group, the Diagnostic-Peripheral group and the
External Expansion group.
