AT!X6=n
X.25 Maximum Window Size. Specifies the X.25 maximum window size. It is
sometimes desirable to have a large window size. This is particularly true for satellite
networks that have significant transmission delays.
sometimes desirable to have a large window size. This is particularly true for satellite
networks that have significant transmission delays.
Maximum window size can never be exceeded. If a larger window size is requested
when the call is established (through X.25 Facilities field), it is negotiated downward
so that the maximum window size is respected.
when the call is established (through X.25 Facilities field), it is negotiated downward
so that the maximum window size is respected.
Default: 7.
Use a value that is greater than or equal to the default window size.
AT!X7=n
X.25 Default Packet Size. Specifies the X.25 default packet size. This packet size is
used if no packet size is specified in the X.25 facilities field when a call is made.
used if no packet size is specified in the X.25 facilities field when a call is made.
Values: 16, 32, 64, 128, 256, 512, 1024, 2048, 4096.
Default: 128.
AT!X8=n
X.25 Maximum Packet Size. Specifies the X.25 maximum packet size. Maximum
packet size can never be exceeded. If a larger packet size is requested when the call is
established, it will be negotiated downward so that the maximum packet size is
respected.

Values: 16, 32, 64, 128, 256, 512, 1024, 2048, 4096.
Default: 256.
AT!X9=n
Terminal Endpoint Identifier (TEI). Specifies the TEI used for X.25 over the
D-channel. Your service provider assigns this value. Possible values are 0 to 63
inclusive.
D-channel. Your service provider assigns this value. Possible values are 0 to 63
inclusive.
Default: 21.
AT!X10=n
Delay Before Opening 1st B-channel. Specifies the amount of time (in seconds) the
throughput on your D-channel must exceed the Opening Threshold (AT!X11=n)
before the 1st B-channel is added to the AO/DI connection.
throughput on your D-channel must exceed the Opening Threshold (AT!X11=n)
before the 1st B-channel is added to the AO/DI connection.
For example, if you specify 5 seconds, and the Opening Threshold is 70%
(AT!X11=70), once the throughput on the D-channel reaches 70%, there will be a
delay of 5 seconds before the 1st B-channel is added to the AO/DI connection. If the
throughput drops below 70% during the 5 seconds, the 1st B-channel will not be
added to the connection.
(AT!X11=70), once the throughput on the D-channel reaches 70%, there will be a
delay of 5 seconds before the 1st B-channel is added to the AO/DI connection. If the
throughput drops below 70% during the 5 seconds, the 1st B-channel will not be
added to the connection.
Range: 0 to 65535.
Default: 5 seconds.
AT!X11=n
1st B-channel Opening Threshold. Specifies the threshold (percentage) that the
throughput on your D-channel must exceed before the 1st B-channel is added to the
AO/DI connection.
throughput on your D-channel must exceed before the 1st B-channel is added to the
AO/DI connection.
Range: 0 to 100.
Default: 70.
AT!X12=n
1st B-channel Closing Threshold. Specifies the threshold (percentage) that the
throughput on your B-channel must be below before the 1st B-channel is dropped
from the AO/DI connection.
throughput on your B-channel must be below before the 1st B-channel is dropped
from the AO/DI connection.
Range: 0 to 100.
Default: 40.
