o call association
Name of the x25 access filter entity that matched an incoming
call, or the name of the x25 access template entity used in
making an outgoing call. This attribute is supported only if
the status attribute port type is set to switched and the status
attribute state is not set to open.
o call direction
Direction of the call on an SVC.
incoming The call is an incoming call.
outgoing The call is an outgoing call.
This attribute is supported only if the status attribute port
type is set to switched and the status attribute state is not set
to open.
o calling address extension
Calling NSAP address that is carried transparently in an incoming
or outgoing call packet. This attribute is supported only if
the status attribute port type is set to switched and the status
attribute state is not set to open.
o calling dte address
Calling DTE address in a call request or incoming call packet
(depending on the value of the status attribute call direction).
This attribute is supported only if the status attribute port
type is set to switched and the status attribute state is not set
to open.
o channel
Channel number of the underlying virtual circuit. This status
is valid only if the port is at a gateway system and the status
attribute state is not open.
o client
Name of the entity that opened the port.
o dte class
Name of the DTE class to which the DTE of the underlying virtual
circuit belongs. This attribute is supported only if the status
attribute state is not set to Open.
o fast select
Specifies whether fast select is in operation for the call.
fast select Fast select in operation.
no fast select Fast select not in operation.
not specified Facility not requested.
with response Fast select with response in operation.
This attribute is supported only if the status attribute port
type is set to switched and the status attribute state is not set
to open.
o group
Name of the x25 protocol group entity (that is, CUG) associated
with an incoming or outgoing call. This attribute is supported
only if the status attribute port type is set to switched and the
status attribute state is not set to open.
o incoming packet size
Packet size, in octets, for incoming data on a virtual circuit.
This attribute is supported only if the status attribute state is
not set to open.
o incoming throughput class
Throughput class for incoming data on a virtual circuit.
o incoming window size
Window size for incoming data on a virtual circuit.
o local dte
Name of the DTE entity associated with the call.
o originally called address
If a call is redirected, this is the DTE address from which the
call was redirected; otherwise, the address is null. This status
is valid only if the status attribute redirect reason is not
[not] redirected. This attribute is supported only if the status
attribute port type is set to switched and the status attribute
state is not set to open.
o outgoing packet size
Packet size, in octets, for outgoing data on a virtual circuit.
This attribute is supported only if the status attribute state is
not set to Open.
o outgoing throughput class
Throughput class for outgoing data on a virtual circuit.
o outgoing window size
Window size for outgoing data on a virtual circuit. This
attribute is supported only if the status attribute state is
not set to open.
o protocol identifier
First four octets of call data in the call. This attribute is
supported only if the status attribute port type is set to
switched and the status attribute state is not set to open.
o pvc
Name of the pvc to which this port belongs. This attribute
is present only if the status attribute port type is set to
permanent.
o redirect reason
Specifies whether a call has been redirected and, if so, the
reason for the redirection.
busy The call has been redirected because the original
destination was busy.
not redirected The call has not been redirected.
out of order The call has been redirected because the original
destination was not operational.
systematic The call has been redirected because all calls to
the original destination have been systematically
redirected.
This attribute is supported only if the status attribute port
type is set to switched and the status attribute state is not set
to open.
o remote port
Port at the source (that is, accessing) node (when the client is
an X.25 server).
o reserved
If the port is associated with a reserved Logical Channel Number
(LCN), this specifies the name of the local DTE entity on which
the LCN is reserved. A null string indicates that the port is
not associated with a reserved LCN. This attribute is supported
only if the status attribute port type is set to switched and the
status attribute state is not set to open.
o reverse charging
Specifies whether reverse charging is in operation for the call.
This attribute is supported only if the status attribute port
type is set to switched and the status attribute state is not set
to open.
o state
Status of the x25 access port entity.
called A call has been received and taken by a user.
calling A user is making a call.
cleared A Clear Indication or Clear Confirmation packet
has been received, or the X.25 Protocol module has
detected an error.
cleared by The port was cleared by network management.
directive
clearing A user has requested that the call should be
cleared.
no communi- Communications with the PSDN have been lost.
cation
open The port is open.
running The associated virtual circuit is available for
data transfer.
synchronizing A user has requested a reset, but the network has
not yet responded with a Reset Confirmation or
Reset Indication packet.
unsynchronized A Reset Indication packet has been received, or
the X.25 Protocol module has detected an error
and the user has not yet responded with a reset
request.
o target address extension
Called NSAP address that is transparently carried in an incoming
or outgoing call packet. This attribute is supported only if
the status attribute port type is set to switched and the status
attribute state is not set to open.
o target dte address
Called DTE address in a call request or incoming call.
This attribute is supported only if the status attribute port
type is set to switched and the status attribute state is not set
to open.
o type
Specifies that the port represents an SVC.
switched The circuit is an SVC.
permanent The circuit is a PVC.
