Description: The ISDN physical layer state according to I.430
f1(1) = inactive; f2(2) = sensing; f3(3) = deactivated; f4(4) = awaiting signal; f5(5) = identifying input; f6(6) = synchronized; f7(7) = activated; f8(8) = lost framing; g1(9) = deactive; g2(10) = pending activation; g3(11) = active; g4(12) = pending deactivation
What is isdnIfLayer1State?
This tracks the ISDN Layer 1 (physical) state according to ITU-T I.430 specification (inactive, sensing, deactivated, awaiting signal, identifying, synchronized, activated, lost framing, or group states). It reflects the signal activation state of the line. Example: state 'f7 (activated)' means the ISDN interface is synchronized and ready to carry calls.
