Interface LEDs The following figures illustrate the FIC-IMA-4E1 and FIC-IMA-8E1 (75-ohm)
panels:

The following table describes the LEDs on the FIC-IMA-4E1/FIC-IMA-8E1 panel:
Interface Cable The FIC-IMA-4E1 card provides four E1 ports and uses a 120-ohm or 75-ohm 4E1
conversion cable. The two types of 4E1 conversion cables look similar. Both of
them have a DB-68 connector at one end for connecting the router. However, the
75-ohm 4E1 conversion cable contains eight coaxial cables and the 120-ohm 4E1
conversion cable contains four twisted pairs.
