This read-write integer is the Peak Cell Rate for the remote end of the connection, which defaults to the same value as the local end's frConnPCR unless explicitly set, but for an asymmetric connection where the local and remote CIRs differ, it should be configured to a different value from frConnPCR. An administrator sets this explicitly whenever the connection's two directions have deliberately different rate profiles. For example, provisioning an asymmetric connection where the near end has a much higher CIR than the far end would require setting frConnRemotePCR to a distinct, typically lower, value than frConnPCR.
