LED indicators are used for multiple purposes as follows
Line status indication: This is the most common mode during normal use of equipment. In this
mode, if a line is idle, the indicator corresponding to it goes off; if a line is in call or in use status
(such as ringing, offhook and caller ID transmission of FXS interface, ringing, offhook and caller
ID detection of FXO interface) the indicator corresponding to it goes on.
Line type indication: This is the mode for installation of equipment or wiring check. This mode
can be entered by disconnecting the network interface (two Ethernet interfaces on the host are
disconnected) when connecting lines at installation stage, or through interface control when the
check is made during normal operation. After entering the mode, LED constant on indicates that
the corresponding line is equipped and is an analog telephone line, LED flashing indicates that
the corresponding line is equipped and is an analog trunk lines; LED off indicates that the
corresponding line is not equipped or is faulty.
System operation status indication: This is the mode for displaying information on system
operation of equipment in specific conditions. Usually, this mode is entered when some prompts
are required to give operator during equipment startup, diagnosis or operation. In this mode, LED
