is the maximum data packet size that will be allowed to pass through this port. A
packet size included in a call setup packet will be used, as long as it is smaller than the
maximum specified here.
will be assigned to an incoming call setup packet if the packet does not include a
packet size. A packet size of 512 bytes is imposed on all protocols except X.25
between the PAD port and the logical port. The
mission out the logical port. (X.25 traffic uses the
the X.25 port.)
Multiple packet sizes (e.g., multipoint SDLC-to-QLLC) require either mul-
tiple logical ports or X.25 address translation (described on page 8-27)
(which allows modification of facilities in Call Request packets).
is the maximum number of sequentially numbered I-frames that can be waiting for
acknowledgment by the (end-to-end) destination device. If this number is exceeded,
no frames will be transmitted until an acknowledgment is received.
There is also a local level-3 window for X.25 traffic. This window will
always be in effect unless the D-bit is set at the attached X.25 device.
will be assigned to an incoming call setup packet if the packet does not include a

if Throughput Class Negotiation is not enabled or if a throughput class is not requested
in the Call Request. This value should not be higher than the line speed specified for
the physical port.
