As the following figure demonstrates, processing of the teleprotection inputs/outputs is dependent on the number of
communication channels and terminals. On two-terminal two-channel systems, they are processed continuously on each
channel and mapped separately per channel. Therefore, to achieve redundancy, the user must assign the same operand
on both channels (teleprotection outputs at the sending end or corresponding teleprotection inputs at the receiving end).
On three-terminal two-channel systems, redundancy is achieved by programming signal re-transmittal in the case of
channel failure between any pair of relays.
