might be set incorrectly. If this problem persists after the
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
SC
channel
byte
except
that
the
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
represent a valid transfer. The upstream C/I bits are
defined as follows:
CI2A, CI1A, CI0A
Monitors status data for channel A
CI2B, CI1B, CI0B
Monitors status data for channel B
MR, MX
Monitor channel handshake bits
