Note
Only the Eiconcard S51 supports ISDN connections.
After you have installed your Eiconcard S51, connect your ISDN
line.
• If you plan to use an Eicon Networks NT1, see “Connecting to
an Eicon Networks NT1,” below.
• If you plan to use a third party NT1 or if you are installing the
Eiconcard S51 outside of North America, see “Making an HSI
Connection” on page 13.
Connecting to an Eicon Networks NT1
To connect to an Eicon Networks NT1, plug one end of the Interface
Cable for ISDN NT1 into the DIN-4 port on the Eiconcard S51; plug
the other end into the DIN-4 port on the NT1. Figure 3 shows how
