This read-write value sets the Peak Cell Rate for the remote end of this connection, defaulting to match the local end's PCR, bbChanUpcPCR, unless explicitly set differently for an asymmetric connection. It exists because ATM connections can have different bandwidth contracts in each direction, and this field is where the far-end's rate is configured when it diverges from the near end's. An admin provisioning an asymmetric connection where downstream traffic needs more bandwidth than upstream would set bbRemoteConnPCR higher, or lower, than the local bbChanUpcPCR rather than accepting the default mirrored value.
