RTS Cronus Manual page 93

Breakout Panels provide a convenient way of expanding the
port capacity of a Cronus Intercom System. Currently, there
are three breakout panels for use with the Cronus MDR
backcard: XCP-32-DB9, XCP-48-RJ45, and XCP-48-Telco.
On the Cronus you can have up to four MDR backcards
mounted on the chassis to give you that many more keypanel
ports.
