power alarm settings are verified, a system fault is
probable, and the user should take measures to
diagnose the problem.
3.31.10. Upstream (Transmit) SC Channel Byte
The upstream SC channel byte looks similar to the
downstream
information quickly transfers the most time-critical
information from the Dual ProSLIC to the GCI bus. Each
upstream SC channel byte transfer from the Dual
ProSLIC lasts for at least two consecutive frames to
