Connection Status Indicators
IBM PCI WAN 2 Port S91
As shown in Figure 1 below, the IBM PCI WAN 2 Port S91 has three status lights
(LEDs) on the end bracket. Two of these lights indicate the status of the ISDN
connection, and the third identifies the card during configuration.
Connection Status Indicators
D-channel Status
The D-channel controls the link to your ISDN
service provider.
Off ........... The line is not active. The cable may
not be connected.
Blinking ... The line is active, but a link can't be
established. This may be a symptom
of incorrect configuration.
Steady...... The ISDN line is active and
operating normally.
B-channel Status
The B-channels are used for the link to the
remote ISDN device.
Off ........... There is no connection.
Blinking... Attempting to connect to the remote
device.
Steady...... The connection is active and able to
transmit data.
Configuration Status
This status light illuminates during
configuration to indicate which card is being
configured. This is most useful when more than
one card is installed in the PC.
Consult the documentation provided with the
configuration software for information about
this status light.
