4.2.4 E1 line indicator
These indicator lights form a matrix. 1, 2, 3 and 4 indicate positions of 4 E1 lines; USED, LOS, LOF,
AIS, CRC and RAL indicate the using status of corresponding E1 and alarms:
USED (green)
:
ON: this E1 line is used;
OFF: this E1 line is unused.
LOS (red)
: ON: loss of E1 signal
LOF (red)
: ON: loss of E1 frame
AIS (red)
:
ON: there is E1 AIS alarm
CRC (red)
: ON: there is E1 CRC error
RAL (red)
: ON: there is alarm at remote E1 line
Note
: If E1 interface is not used, there no corresponding alarms.
4.2.5 Definition of mute, DIP switch and interfaces
MUTE
:
This is a lockless button used to mute alarm sound. There will be alarm sound if there are alarms.
This button only mutes the present sound. And if there are new alarms there will be new alarm
sound.
CONSOLE
:
A RJ45 connector to connect PC and RC3000 device for Hyper Terminal configuration (through the
cable offered by Raisecom, and please plug the cable in RJ45 connector first and then the DB9 serial
interface connector on PC, this will protect the serial interface), set the first bit of DIP-switches ON,
startup Hyper Terminal and then you can configure the device.
LINK
:
There are two RJ45 connectors for network management: UP and DOWN.
UP (RJ45 connector): PC network management interface access. Through this interface a PC can
manage all the RC3000 devices in this network (the second bit of DIP-switches should be ON).
DOWN (RJ45 connector): This is a concatenation interface for management of RC3000 or other
connected devices.
