XOT (X.25 Over TCP with X.25 termination).
If the peer X.25 device is attached to a remote XOT router, then select “XOT”, and specify the IP
address and TCP port number of the remote XOT peer device.
XOT remote IP address: IP Address of the remote XOT peer. Relevant only when Local interface
(above) is set to “XOT”.
XOT remote TCP port: TCP port of the remote XOT peer. The normal default is port 1998. Relevant
only when Local interface (above) is set to “XOT”.
X.25 connection type: Type of logical channel connection made to the remote X.25 host, SVC or PVC.
Calling address: The X.121 address inserted into calling (source) address field of the outbound call
request. A wildcard “?” may be entered into the address that will be replaced by the least significant
decimal digit of the remote TCP port number. Not used for PVC.
Calling address: The X.121 address inserted into called (destination) address field of the outbound
call request. Not used for PVC.
Call User Data: Specifies the userdata to be inserted into the call request. This field includes any
Protocol ID bytes (PID). Examples of PID encoding are “01:00:00:00” for PAD (X.29) calls and
“03:01:01:00” for OSI Transport Layer calls.
Protocol Handler: Specifies the handling of protocols above the X.25 packet layer 3. Currently, X.29 is
the only option available. X.29 does partial handling of X.29 messages contained in Q-bit packets, and
is only effective when Conversion Type RAW, RAW-MBIT, MBIT, RFC1006, RBP, LINE, or IAC-ESC is
selected.
Local LCN: For PVC connection type, specifies the Logical Channel Number to connect.
XOT remote LCN: For XOT conversion type, and PVC connection type: specifies the Logical Channel
Number at the X.25 interface of the remote XOT peer.
XOT remote interface: For XOT conversion type and PVC connection type: specifies the interface
name <in brackets> at the remote XOT peer. For example: <hdlc0>
Window Size: Window size negotiation which will be initiated during call setup for SVC, or the size
used for a PVC (not negotiated).
Packet Size: Packet size negotiation which will be initiated during call setup for SVC, or the size used
for a PVC (not negotiated).
Throughput Class: Data rate to be negotiated during call setup. Not used for PVC.
Reverse: Specifies that the call request is reverse charged (collect call). Not used for PVC
Fast Select: Allows the inclusion of user data in clear request packets, and allowing up to 128 bytes of
user data in call request/confirm, and clear request packets. Not used for PVC.
Calling Address Extension: DTE facility inserted into the call request facility field.
Called Address Extension: DTE facility inserted into the call request facility field.
