The Legacy CDR format has an on-disk format defined using Google Protocol Buffers (aka protobuf).
There is a common "types definition" schema file that is used by multiple Sentinel Services for their CDRs. These types are called "base types". Each Sentinel Service then defines its own CDRs using these types and defining its own types.

Base types
The base types are used in CDRs for Sentinel SS7, Sentinel Diameter Mediation.
