The Constellation radio can be installed in a standard 19-inch equipment rack.
A fully protected terminal configuration requires 15 RMS (rack mounting
spaces). A low/medium capacity repeater can be mounted on a single rack,
however, an additional RMS is required below for ventilation, and another
RMS above for access to the ACU. A high capacity radio repeater is installed in
back-to-back terminals.
