LED NAME DESCRIPTION
General Operation LEDs (one set on each MultiVOIP model)
Power Indicates presence of power.
Boot
After power up, the Boot LED will be on briefly while the
MultiVOIP is booting. It lights whenever the MultiVOIP is
booting or downloading a setup configuration data set.
Ethernet
FDX. LED indicates whether Ethernet connection is
half-duplex or full-duplex (FDX) and, in half-duplex
mode, indicates occurrence of data collisions. LED is
on constantly for full-duplex mode; LED is off
constantly for half-duplex mode. When operating in
half-duplex mode, the LED will flash during data
collisions.
LNK.
Link/Activity LED. This LED is lit if Ethernet
connection has been made. It is off when the link is
down (i.e., when no Ethernet connection exists).
While link is up, this LED will flash off to indicate data
activity.
D-Channel Operation LEDs (one for each ISDN line)
D ISDN D-channel & physical layer indicator. One “D”
LED for each ISDN-BRI connection. The “D” LED is
off when the BRI physical layer is de-activated.* It
flashes when a connection is being established on the
physical layer. It is on when the physical layer has
been activated. It flickers to indicate D-channel traffic.
*If the voip is running in terminal mode and its BRI
line is unplugged, the D LED goes off. However, if the
voip is running in network mode and its BRI line is
unplugged, its LED will flash at regular interval.
B-Channel Operation LEDs (one for each B-channel)
XMT Transmit . This indicator blinks when voice packets
are being transmitted onto the B-channel.
RCV Receive . This indicator blinks when voice packets
are being received on the B-channel.
