[time-nuts] NTGS55A Undocumented TSIP data

[Mark Sims]

I have poked and prodded the Nortel 8F-AE packet some more.  Here is what seems to be in it:

u08 subcode;      // packet ID subcode
u16 zero;         // ??? always zero
u08 leds;         // led status
u08 ffom;         // frequency figure of merit
u08 tfom;         // time figure of merit
u08 hold;         // holdover state
u08 pll;          // pll state
u08 dis;          // disciplining mode
u08 flash;        // active firmware ID code
u08 b1,b2;        // ??? always zero
u08 log_count;    // number of events in the log (or perhaps an error counter)
u16 op_status;    // operation status
u16 hw_status;    // hardware status
float pps_val;    // related to pps error (in ns)
float osc_val;    // related to osc error (in ppb)
