Use the SET MODULE X25-PROTOCOL command to create or modify the
parameters of the Protocol Module component in the volatile data
base. Use the DEFINE MODULE X25-PROTOCOL command to create or modify
the parameters of the Protocol Module component in the permanent data
base.
Use separate SET MODULE X25-PROTOCOL commands to a specify a DTE with
its associated parameters, a group with its associated parameters and
the network profile.

All underscores found in parameters must be replaced with spaces
when parameters are used in NCP commands.
1 – ALL
Can be used with DTE, GROUP or NETWORK. It selects all parameters for the specified component or for all known DTEs, groups or networks.
2 – CALL TIMER
Specifies a timer that starts when a request to set up an X25 virtual circuit is transmitted, and whose termination clears the request if no response has been received. Specify a value in the range 1 to 255. By default the timer takes the network value specified by the PROFILE parameter.
3 – CHANNELS
Specifies a list of logical channel numbers (LCNs) reserved for outgoing calls. The list can consist of one or more LCNs. Separate LCNs with hyphens to indicate ranges, or with commas to indicate separate list items. Specify a value in the range 0 to 4095 for each LCN. If a DTE is to make outgoing calls you must specify this parameter when defining the DTE.
4 – CLEAR TIMER
Specifies a timer that starts when a request to clear an X25 Virtual circuit is transmitted, and whose termination retransmits the clear request if not response has been received. Specify a value in the range 1 to 255. By default, the timer takes the network value specified by the PROFILE parameter.
5 – COUNTER TIMER
Sets a timer whose expiration causes a DTE counter logging event. Specify a decimal integer in the range 1 to 65,535.
6 – DEFAULT
6.1 – DATA
Specifies the default packet size for X25 virtual circuits. This value must be at least 5 bytes less than the MAXIMUM BLOCK value you specify in the SET LINE command and must be a power of 2. Specify a value in the range 16 to 4096 bytes. By default packet size takes the network value specified by the PROFILE parameter.
6.2 – WINDOW count
Specifies the default window size for X25 virtual circuits, that is, the maximum number of packets for which outstanding acknowledgments are allowed. Specify a value in the range 1 to 127. By default, window size takes the network value specified by the PROFILE parameter.
7 – DTE
Identifies a local DTE. If you specify the DTE qualifier, you must associate with it: NETWORK network-name or KNOWN NETWORKS
8 – KNOWN
Can be used with DTES, NETWORKS and GROUPS. KNOWN DTES selects all known DTEs on the network specified or all known networks. KNOWN NETWORKS selects all known networks. KNOWN GROUPS selects all known groups.
9 – INTERFACE code
Specifies the way in which the processor operates. This parameter can
only be used with the ISO8208 profile. The parameter can take one of
the following values:
DTE The processor operates as a DTE.
DCE The processor operates as a DCE.
NEGOTIATED The processor can operate either as a DTE or DCE. The
processor automatically selects the correct method of operation.
The default is DTE.
10 – INTERRUPT TIMER secs
This is the interrupt timer (ISO T26 timer). This parameter can only be used with the ISO8208 profile. Specify a value in the range 1 to 255. If you do not specify a value there is no time limit on interrupt acknowledgments.
11 – LINE line-id
Identifies the line associated with the DTE. Specify a line name in the format dev-c[u]. This parameter is mandatory when you specify a DTE for the first time.
12 – MAXIMUM
12.1 – CIRCUITS count
Specifies the maximum number of circuits for the DTE. By default, the maximum is 255.
12.2 – CLEARS count
Specifies the maximum number of attempts to clear an X25 virtual circuit. Specify a value in the range 1 to 255. By default the value is the network value specified by the PROFILE parameter.
12.3 – DATA bytes
Specifies the maximum packet size for X25 virtual circuits. This value must be at least 5 bytes less than the MAXIMUM BLOCK value you specify in the SET LINE command and must be a power of 2. Specify a value in the range 16 to 4096 bytes. By default the value taken is the network value specified by the PROFILE parameter.
12.4 – RESETS count
Specifies the maximum number of attempts to reset an X25 virtual circuit. Specify a value in the range 1 to 255. By default, the count takes the network value specified by the PROFILE parameter.
12.5 – RESTARTS count
Specifies the maximum number of attempts to restart an X25 virtual circuit. Specify a value in the range 1 to 255. By default, the count takes the network value specified by the PROFILE parameter.
12.6 – WINDOW count
Specifies the window size allowed for X25 virtual circuits, that is, the maximum number of packets for which outstanding acknowledgments are allowed. Specify a value in the range 1 to 127. By default, the window size takes the network value specified by the PROFILE parameter.
13 – GROUP
Identifies a closed user group (CUG) or bilateral closed user group (BCUG) or specifies all known groups.
13.1 – DTE dte-address
Identifies the local DTE associated with the group name. This parameter is mandatory when creating a group.
13.2 – ALL
Copies the group parameters from the permanent data base into the volatile data base. (Used only with the SET MODULE X25-PROTOCOL command.)
13.3 – NUMBER group-number
Specifies the CUG or BCUG number. Specify a two-digit number for a CUG and a four-digit number for a BCUG. You can omit leading zeroes. This parameter is mandatory when creating a group.
13.4 – TYPE BILATERAL
Specifies the user group as a BCUG. Omit this parameter if the user group is a CUG.
14 – ALL
Copies the network parameters from the permanent data base into the volatile data base. (Used only with the SET MODULE X25-PROTOCOL command.)
15 – NETWORK net-name
Identifies a network.
16 – PROFILE profile-name
Specifies a profile to be used on the network. The profile-name is a character string of up to 32 characters. This parameter is mandatory.
17 – RESET TIMER secs
Specifies a timer that starts when a reset is transmitted, and whose termination retransmits the reset if no response has been received. Specify a value in the range 1 to 255. By default the timer takes the network value specified by the PROFILE parameter.
18 – RESTART TIMER secs
Specifies a timer that starts when a restart is transmitted, and whose termination retransmits the restart if no response has been received. Specify a value in the range 1 to 255. By default, the timer takes the network value specified by the PROFILE parameter.
19 – STATE dte-state
Specifies the operational state of the DTE as follows:
ON The DTE is available for normal use
OFF The DTE is not in use
SHUT The DTE is to be closed down when all present activity has
ceased
19.1 – PROFILE
Specifies a profile to be used on the network. The profile-name is a character string of up to 32 characters. This parameter is mandatory.
20 – CALL TIMER seconds
Specifies a timer that starts when a request to set up a virtual circuit is transmitted, and whose expiration clears the request if no response has been received. Specify a value in the range 1 to 255. By default, the timer takes the network value specified by the NETWORK parameter.
21 – CLEAR TIMER seconds
Specifies a timer that starts when a request to clear a virtual circuit is transmitted, and whose expiration retransmits the clear request if no response has been received. Specify a value in the range 1 to 255. By default, the timer takes the network value specified by the NETWORK parameter.
