Appendix B: Technical Information DIVA LAN ISDN Modem indicator lights 157
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.
Orange Indicates a phone call.
Off No call activity on the specified B-channel.
Flashing An incoming or outgoing call is being established on the B-channel.
Steady A call is connected and the channel is in use.
State Description
Off The ISDN physical interface is not active. The LINK light may provide additional information.
Flashing Indicates that the ISDN physical interface is initializing. Flashing stops when initialization is
complete. Continuous flashing indicates an error in the initialization process (usually due to
incorrectly entered SPIDs). Data transmission may not be possible on the D- or B-channels until the
problem is resolved. The console port can be used to further diagnose the problem.
If you are using AO/DI, continuous flashing indicates that the DIVA LAN ISDN Modem cannot
establish the X.25 data link layer on the D-channel.
Steady The ISDN physical interface has been initialized and is ready to place or receive calls on the D- and
B-channels.
State Description
Off The ISDN physical interface is not synchronized, or is improperly connected. Check your ISDN
cable.
Flashing The ISDN physical interface is synchronizing. Continuous flashing indicates a problem with the
ISDN line:
• Make sure that the line is plugged in and that you are using the correct interface (S/T or U).
• Check your termination requirements. See “Termination” on page 161.
Steady The ISDN physical interface is active. Lights D, B1, and B2 may provide additional status
information.
