Use addresses from call in accept for LAPD:
When this parameter is set to “On” then when X.25 is answering a call on the LAPD interface
the called and calling addresses from the CALL packet are used in the X25 CALL CNF (call
confirm packet) that the unit sends to answer the call.
Use addresses from call in accept for LAPB:
When this parameter is set to “On” then when X.25 is answering a call on the LAPB interface
the called and calling addresses from the CALL packet are used in the X25 CALL CNF (call
confirm packet) that the unit sends to answer the call.
Use addresses from call in accept for XOT:
When this parameter is set to “On” then when X.25 is answering a call on the XOT interface
the called and calling addresses from the CALL packet are used in the X25 CALL CNF (call
confirm packet) that the unit sends to answer the call.
Reset XOT PVC if Initiator:
When this parameter is set to “On” the unit is responsible for resetting the links when an XOT
PVC comes up. This parameter should only be set to “Off” when it is known that the responder
will reset the links.
Reset XOT PVC if Responder:
When this parameter is set to “On” the unit is responsible for resetting the links on XOT PVC
links when it is the responder. The default for this parameter is “Off”.
Include length of header in IP length header:
For all X.25 calls which include an IP header length indication (i.e. IP Length Header is set to
“On” a TPAD or PAD, etc.) this parameter specifies whether the length indicated includes or
excludesthe length of the header itself.
By default it is “Off”, in which the length of the header is NOT included in the value. For exam-
ple,
say we had one byte of data of value 67 to encode. Then “00 01 67” is the encoding if this
param eter is set to “Off” as the length (00 01) is 1 because the length does not include the
length of the header. When set to “On” the length of the IP header is included in the value, i.e.
“00 03 67” is the encoding as the header bytes are included.
