Object
column
SNMPv2-SMICounter64
For T1, the Loss Of Signal failure is declared upon
observing 175 +/- 75 contiguous pulse positions with no
pulses of either positive or negative polarity. The LOS
failure is cleared upon observing an average pulse
density of at least 12.5% over a period of 175 +/- 75
contiguous pulse positions starting with the receipt of a
pulse.
For E1 links, the Loss Of Signal failure is declared when
greater than 10 consecutive zeroes are detected (see
O.162 Section 3.4.4).
