Protocol Switch
Configuration – Network > Protocol Switch
The Protocol Switch software available on some models provides X.25 call switching
between the various protocols and interfaces that may be available including:
Interface /
Protocol
Description
Off/None Data will not be switched from / backed-up to this protocol
LAPD
Data will be switched from / backed-up to LAPD using the
X.25 service.
LAPD X
As above but the actual LAPD instance used will be
determined by the NUA.
LAPB 0 Data will be switched from / backed-up to LAPB 0.
LAPB 1 Data will be switched from / backed-up to LAPB 1.
LAPB 2 Data will be switched from / backed-up to LAPB 2.
LAPB 0 PVC
Data will be switched from / backed-up to an X.25 PVC on
LAPB 0.
LAPB 1 PVC
Data will be switched from / backed-up to an X.25 PVC on
LAPB 1.
LAPB 2 PVC
Data will be switched from / backed-up to an X.25 PVC on
LAPB 2.
XoT
Data will be switched from / backed-up to an XOT (X.25
over TCP/IP) connection.
XoT PVC
Data will be switched from / backed-up to an XOT PVC
connection.
TCP stream
Data will be switched from / backed-up to a TCP socket.
The socket’s IP address will be determined from the IP
stream port setting.
UDP stream
This is similar to the TCP stream setting but instead of
switching onto a TCP socket, data is switched onto a UDP
socket. In the case of switching from X.25. the effect is
that a UDP frame will be sent for each packet of X.25 data
being switched.
VXN
Data will be switched / backed-up to Datawire’s VXN
protocol
SSL Data will be switched / backed-up to SSL
DialServ
Data will be switched backed-up to an analogue modem via
the built in DiaslServ daughter card.
