Figure 223   FIC-1CT3 panel

The following table describes the LEDs on the card panel.

Refer to “FIC-1CE3” on page 178.

The interface cable for the FIC-1CT3 is the same as that for the FIC-1CE3 and is 
connected in the same way.

FIC-4BSE, the four-port ISDN BRI interface card, transmits, receives, and processes 
four channels of ISDN BRI S/T data traffic on ISDN BRI S/T interfaces.

The FIC-4BSE differs from the FIC-4BS only in the way they set matched resistance 
for an ISDN BRI S/T interface: the FIC-4BS uses jumpers while the FIC-4BSE uses 
DIP switches.

The FIC-4BSE can work in dial mode or leased line mode.

The following table describes the interface attributes of the FIC-4BSE.

Table 125   LEDs on the FIC-1CT3 panel

LINK/ACT 

ON means the carrier signal has been 
received.

OFF means no carrier signal has been 
received.

Blinking means data is being transmitted 
or/and received. 

LP/AL 

ON means the interface is in a loopback.

Blinking means an AIS, LFA, or RAI alarm 
signal is present.

OFF means no loopback or alarm is 
present. 

AIS = Alarm indication signal; LFA = loss of frame alignment; RAI = Remote alarm indication
