X.25 Calls
This chapter provides operating instructions for X.25
Generic Packet Mode Support provided by the
Aurora
Plus
.
The
Aurora
Plus
supports incoming and outgoing X.25 packet
switched calls, for test purposes, over the D channels of the
ETSI ISDN Basic Rate interfaces. When you use
Aurora
Plus
to
make a X.25 call it acts as the DTE (Data Terminal
Equipment).
What is D-channel X.25 ?
This is an X.25 protocol with access to ISDN virtual circuit
services on the D-channel. A call is made to the remote
equipment using the D-channel. Because the amount of
ISDN signalling data is very low, both the ISDN signalling
data and the X.25 packet data can be multiplexed on the
same D-channel.
