FIC-1AE3 185
■ For an ISDN U interface line, adapt the interface with an NT1 by inserting one
end of the S/T interface cable into the S/T port on the NT1 and the other end to
the BRI port on the FIC-4BSE.
■ For an ISDN S/T interface line, directly connect the cable to the BRI port on the
FIC-4BSE.
FIC-1AE3
Introduction FIC-1AE3, the 1-port 34 Mbps ATM-E3 interface card, provides these functions:
■ Two ATM cell mapping modes: ATM direct mapping (ADM) and physical layer
convergence protocol (PLCP).
■ Scrambling in data transmission.
■ Line clock (when working as DTE interface) and internal clock (when working
as DCE interface).
■ Four types of test measures: local cell loopback, local loopback, remote payload
loopback, and remote line loopback.

You may equip your router with FIC-1AE3 cards to its full capacity. Yet, you are
recommended to install only one FIC-1AE3 on it, whatever its model is, to ensure
performance of some key services.
