What is bopSapOprPortClockSource?

Shows the active bit-clock source for the port: internal (both clocks generated locally), external (both supplied by the far end), split (Tx internal, Rx external), or slave. Diagnosing 'no clock' or framing errors on a leased line often starts by checking this matches how the line is actually wired.
