1.5.5 LED Indicators
Power Green On = Power active, Config by DIP switch
Flash = Config by console or SNMP
E1/T1 Mode Stateful Green = E1 mode (75 ohm)
Green/Flash = E1 mode (120 ohm)
Off = T1 mode (100 ohm)
Red/flash = Error in termination setting
Remote Error Stateful Green = remote no error
Red = remote has errors
Off = unknown or no optical link
Optical BER
(Bit Error Rate)
Stateful Green = 0 error rate
Green/flash = 0 to 10
-6
error rate
Red/flash = 10
-6
to 10
-3
error rate
Red = more than 10
-3
error rate
(Optical) Link Stateful Green = Link Good
Red = Link failure
E1/T1 Channel (1~4) Stateful Green = In Service
Off = Out of Service
Red = Loss of Signal
Red/flash = loop back test active
Active (Phone) Stateful Off = On Hook
Green = Off Hook & Connected OK
Green/flash = call out or incoming call (ringing)
Red/flash = Off Hook & connect failed
Red = No Phone Option Installed
SNMP (rear panel) Green Active: ON = SNMP active (flash 1/sec)
Active: OFF = no SNMP option
Link: ON= LAN link OK; OFF = No Link
