Microtronix Access User Guide
XOT TCP Port:
TCP port of the remote XOT peer. The normal default is port 1998. Relevant only
when Device (above) is set to “XOT”.
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.
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.
Example encoding for OSI NSAP address 36-12345678-123 (AFI-IDI-DSP) is:
“3600000012345678123F”
