AIS Red:
Steady Light: There is AIS alarm in E1 data channel of local optical receiving signal;
Flash: There is AIS alarm in E1 data channel of remote optical receiving signal;
Steady Off: There is no AIS alarm in E1 data channel of local/remote optical receiving
signal;
CRC Red:
Steady Light: There is CRC4 checkout alarm in E1 data channel of local optical
receiving signal;
Flash: There is CRC4 checkout alarm in E1 data channel of remote optical receiving
signal;

optical receiving signal;
LOF Red:
Steady Light: There is G.704 out of frame alarm in E1 data channel of local optical
receiving signal;
Flash: There is G.704 out of frame alarm in E1 data channel of remote optical
receiving signal;
Steady Off: There is no G.704 out of frame alarm in E1 data channel of local/remote
optical receiving signal;
LOOP Yellow:
Steady Light: Local bidirectional loopback indication;
Flash: Remote bidirectional loopback indication;
Steady Off: There is no loopback in local/remote side.
TD Green:
Flash: There is data transmission in V.35 interface, and the flash frequency stands for
the different bit rate of V.35 interface. When the bit rate is 64Kbps the flash frequency is
lowest and the 2048Kbps the highest.
Steady Off: There is no transmission in V.35 interface.
RD Green:
Flash: There is data receiving in V.35 interface, and the flash frequency stands for the
different bit rate of V.35 interface. When the bit rate is 64Kbps the flash frequency is
lowest and the 2048Kbps the highest.
