Note:
The standard equipping package for the SIC-1ADSL-I includes a regular telephone
cable, but the splitter needs a separate order.
2.12.5 Connecting the Interface Cable
To connect the interface on the SIC-1ADSL-I card, you need to install a splitter. Follow
these steps:
Step 1: Plug one end of a telephone cable into the RJ-11 port on the SIC-1ADSL-I on
the router and the other end into the internal ADSL-I port on the splitter;
Step 2: Connect an ISDN NT1 to the splitter using another telephone cable.
Step 3: Connect the external ADSL-I port on the splitter to ISDN using a third telephone
cable.

used to transceive and process of ISDN BRI S/T traffic flows. SIC-1BU/SIC-2BU is
short for 1/2-port ISDN BRI U interface card, which is mainly used to transceive and
process ISDN BRI U traffic flows.
Both SIC-1BS/SIC-2BS and SIC-1BU/SIC-2BU have two working modes: dial-up and
