®

		ISDN			Ethernet	FAULT POWER
B1	B2		D	E1	E2 E3

B1, B2

Indicates the status of the B-channels.

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.

D

Indicates the status of the ISDN D-channel.

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.

LINK

Indicates the status of the ISDN physical interface.

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.
