NCD terminals can use ethernet or XRemote over ISDN. See the article
in xremote_info for using XRemote.

Tests of NCDs with ISDN units show that the NCDs perform best with
the following setup.

ISDN setup for remote site:

NCD with a 10baseT card and 3.1.0 or later X Server PROMS or an NCD 
with an ESP card and a Flash Card for local booting. 

Host side ISDN interface combinet 400 unit with compression enabled.

Remote NCD side ISDN interface combinet 150 unit with compression
enabled.

The Combinet 400 unit is a ISDN to ethernet bridge with a 10baseT and a
10base2 ethernet interface, the Combinet 150 unit is a ISDN to single
ethernet interface bridge with only a 10baseT interface which will
connect directly to a 10baseT interface on the NCD or to a 10baseT 
transceiver.

So the bottom line is for the best performance at a remote location
using ISDN you do not need XRemote, but you will need a PROM or Flash
based NCD with a 10baseT interface connected to a Combinet 150 unit
which will dial up a Combinet 400 unit that is connected to the
ethernet.
