DCP Series X.25 Packet Switched Communications Software (PSCS ...

Procedure
Provide the following additional configuration statements:
• A PRCSR statement to define the other DCP.
• A TRUNK statement.
Configuring Standard X.25 PSCS Capabilities
Although neither the PRCSR nor the TRUNK statements have X.25 PSCS specific
parameters, they are included here for clarity.
• A DTETYPE statement that specifies the following on the LEVEL4 parameter:
–
Specifies PDNTRUNK as the Level 4 program to which X.25 PSCS should
route data received from the DTE that is defined later in this procedure.
– The maximum number of switched virtual circuits this trunk may use. The
default is 1.
– The number of attempts to initially establish, or to reestablish, a virtual circuit
connection that has been cleared because of inactivity. Specify between 0 and
255 attempts. If you do not specify a value or if you specify 0, X.25 PSCS
continues to attempt to initially establish or reestablish a circuit until it is
successful.
– The amount of time between attempts to initially establish or reestablish a
virtual circuit connection that has been cleared because of inactivity. Specify
between 0 and 65,535 seconds. If you do not specify a value or if you specify
0, an attempt is made every 60 seconds.
– The amount of time between transmission of network data units (NDUs),
before a circuit is cleared. Specify between 0 and 65,535 seconds. If you do
not specify a value or you specify 0, X.25 PSCS does not automatically clear
the circuit.
– The diagnostic code that X.25 PSCS encodes in clear packets when a trunk
goes into an idle condition. Specify a value between 1 and 255. The default is
168.
Note: You must specify these values in the order listed. See the example
following this procedure for more information.
