Description
Detected alarm indication signal in
timeslot 16 according to ITU-T G.775.
Indicates the incoming time slot 16
contains less than 4 zeros in each of
two consecutive time slot 16
multiframe periods.
A short exists between the transmit
pair for at least 32 consecutive pulses.
For use by MTS personnel.
The frequency of the transmit clock is
less than the frequency of the transmit
system interface working clock. A
frame is repeated.
The alarm signal sent by a remote T1/E1
device to indicate that it sees no receive
signal or cannot synchronize on the
receive signal.
Signaling has been frozen at the most
recent values due to loss of frame
alignment, loss of multiframe alignment
or due to a receive slip.
In D4 or ESF mode, displayed value will
increment if multiframe alignment has
been lost or if loss of frame alignment has
been detected.
The time slot 16 data stream contains all
zeros for at least 16 contiguously received
time slots.
