3Com Router Module Guide Figure 2-11 SIC-2BS panel Chapter 2 Smart Interface Cards Figure 2-12 SIC-2BU panel The status description of the LEDs is given in the following table: Table 2-8 Description of the LEDs on SIC-BS and SIC-BU panels LED Description OFF means B1 channel is idle. Blinking means B1 channel is occupied and B1 data communication is being conducted. OFF means B2 channel is idle. Blinking means B2 channel is occupied and B2 data communication is being conducted. OFF means deactivation. Blinking means activating process. ON means ACT active status. OFF means the power to the SIC is disconnected (caused by the failure of ON power supply to the SIC and so on). ON means the SIC is normally powered on. Note: For ISDN, "active" describes the action or process that a terminal device synchronizes the network clock. It belongs to the physical layer category. In order to decrease power consumption of exchange device and etc., usually the terminals and network (LT port) should be "deactivated". 2.3.5 Interface Cable Both of ROUTER 2-PORT ISDN-S/T SIC and ROUTER 2-PORT ISDN-U SIC use the telephone cable with ferrite core. 2-11

The status description of the LEDs is given in the following table:
Table 2-8
Description of the LEDs on SIC-BS and SIC-BU panels
LED
Description
B1
OFF means B1 channel is idle. Blinking means B1 channel is occupied and
data communication is being conducted.
B2
OFF means B2 channel is idle. Blinking means B2 channel is occupied and
data communication is being conducted.
ACT
OFF means deactivation. Blinking means activating process. ON means
active status.
ON
OFF means the power to the SIC is disconnected (caused by the failure of
power supply to the SIC and so on). ON means the SIC is normally
powered on.
Note:
For ISDN, “active” describes the action or process that a terminal device synchronizes the network clock.
It belongs to the physical layer category. In order to decrease power consumption of exchange device
and etc., usually the terminals and network (LT port) should be “deactivated”.

Interface Cable
Both of ROUTER 2-PORT ISDN-S/T SIC and ROUTER 2-PORT ISDN-U SIC use the
telephone cable with ferrite core.
