Relative frequency and bit slips (Option 010)

2.048 Mb/s only

Measures relative frequency of, and bit slips between, two ITU-T G.703 2 Mb/s signals. Results displayed as + ve and − ve peak wander (UI), cumulative bit slips, frequency offset (ppm) and graph of bit slips (256, 16 UI). Reference input level: 0 to

−20 dBm.

Connector: BNC 75 ohm,

unbalanced.

ITU-T M.2110 and M.2120 analysis

(Option 210)

Measurement start at user- specified time. Summary print of current settings and counts.

ITU-T M.2110 analysis

(for bringing paths into service): 1-day and 7-day tests. Wait/pass/fail test relative to user- defined percentage path allocation.

ITU-T M.2120 analysis

(for in-service monitoring):

15-minute and 24 hour-contiguous measurement of errored and severely errored seconds based on user-defined path allocation.
