Ethernet optical port L/A LED OFF or OLOS LED ON

Ethernet optical ports L/A light off indicate that the corresponding Ethernet
does not establish
no received light. Can check the corresponding fiber is connected or not, the using
single-fiber module and the equipment connected to the same emission wavelength
(should using wavelength as pair optical modules), and device working properly or
not.

E1/T1 Alarm LED ON

There are two groups of LEDs, PKT LOS and LOS for E1 alarms LEDs.
When E1 LOS LED is on, loss of E1 signal fault is detected by AN-TDM-IP.
Possible causes include:
The downstream equipment such as telephone exchange or PCM terminal
is powered off.
The E1 cable connection looses or broken.
E1 LOS LED blinks when respective input E1 signal is AIS, i.e. the content of
E1 data is all 1. Such alarm indicates fault conditions on the part of the downstream
equipment.
E1 LOS site is controlled by Dip Switch RA state. When RA Dip Switch ON, the
red LEDs indicate remote E1 LOS state. When RA Dip Switch OFF, the red LEDs
indicate local E1 LOS state.
