ALTER LINE Command
ZL3-WINDOW
specifies the number of packets that can be outstanding without an
acknowledgment from the network. If the modulus for the packet counters
indicated by field ZL3-MOD is 8, ZL3-WINDOW can be assigned a value in the
range 2 through 7; otherwise, it can be assigned a value in the range 1 through
15. This field corresponds to the SYSGEN modifier L3WINDOW.
ZPROG
specifies the file name of the program to be downloaded to the CLIP. The value
assigned to this field must be the name of an existing GUARDIAN 90 file. This
field is valid only for 6100 or 6105 X25AM lines. This field corresponds to the
SYSGEN modifier PROGRAM.
ZPVC-RANGE
is a pair of integers that specifies the range of logical channels to be used for
Permanent Virtual Circuits (PVCs). The first integer of the pair specifies the
lower end of the range, and the second integer specifies the upper end. To
assign a range, both integers must have values in the range 1 through 4095 or,
for TRANSPAC, in the range 0 through 4095. In addition, the value of the first
integer must be less than or equal to the value of the second. This range must
not overlap with the range of logical channels to be used for Switched Virtual
Circuits (SVCs). To clear an explicitly specified range, assign the value -1 to
the first integer of the pair. This field has no corresponding SYSGEN modifier.
ZRETRIES
specifies the number of level-2 retries to be attempted before a disconnect
(N2). This field can be assigned a value in the range 1 through 255. This field
corresponds to the SYSGEN modifier L2RETRIES.
ZREXMIT-TIMEOUT
specifies the time interval to wait for an acknowledgment before a
retransmission is attempted (the level-2 T1-timer interval). This field
corresponds to the SYSGEN modifier L2TIMEOUT.
ZSVC-RANGE
is a pair of integers that specifies the range of logical channels to be used for
Switched Virtual Circuits (SVCs). The first integer of the pair specifies the lower
end of the range, and the second integer specifies the upper end. To assign a
range, the value assigned to the first integer must be greater than the value of
the upper bound of the range of logical channels to be used for PVCs and less
than or equal to 4095. The value assigned to the second integer must be
greater than the value of the first integer and less than or equal to 4095. If no
value is assigned to the second integer, the X25AM subsystem will calculate
the upper bound. To clear an explicitly specified range, assign the value -1 to
the first integer of the pair. This field has no corresponding SYSGEN modifier.
