  // Service types:
  // - TBC: Time Boundary Clock - Receives time from a master clock and distributes it to downstream clocks
  // - TGM: Telecom Grandmaster - Acts as the primary source of time in the network (receives from GNSS or SMA)
  // - T-TSC: Telecom Time Slave Clock - Synchronizes to an upstream master clock
  
  // Time sources:
  // - GNSS: Global Navigation Satellite System provides time to Controller-0 NIC1
  // - SMA: SubMiniature version A connector provides clock to Controller-0 NIC2
