DIVA LAN ISDN Modem indicator lights
The front panel lights show you the status of the DIVA LAN ISDN Modem.
B1, B2
Indicates the status of the B-channels.
D
Indicates the status of the ISDN D-channel.
LINK
Indicates the status of the ISDN physical interface.
State Description
Green Indicates a data call.

line is idle, many networks automatically disconnect the D-channel (turning off both D and
LINK) to conserve power.

X.25 data link layer on the D-channel.

receives a call.
State Description

line is idle, many networks automatically disconnect the D-channel (turning off both D and

wrong interface is being used (S/T or U).
