signal is an unframed All One signal that replaces the normal traffic signal
YEL Activates when an incoming remote alarm is received from the T1 device indicating that a
failure has occurred in the received direction.
LOS Activates when no T1 signal is present from the connected T1 equipment. LOS is
activated after receiving 192 consecutive zeros.
BPV Activates when the incoming T1 stream presents bipolar violations (BPVs).
