CALL command: Make an X.25 call
The full structure of a CALL command is:
CALL [<facilities->]<address>[D<user data>]
where:
• <facilities-> is an optional list of codes indicating the facilities to be requested in the call
(separated by commas, terminated with a dash)
• <address> is the destination network address.
• <user data> is any optional user data to be included with the call.
The facility codes supported are:
• F: Fast select-no restriction
• Q: Fast select-restricted response
• Gnn: Closed User Group
• Gnnnn: Extended Closed User Group
• R: Reverse charging
• N<NUI>: Network User Identity code (NUI)
Example
The following command places a call to address 56512120 using reverse charging and specifying
Closed User Group 12. The string MYNUI is your Network User Identity. The string Hello appears
in the user data field of the call packet.
CALL R,G12,NMYNUI-56512120DHello
Note The particular facilities available vary among X.25 service providers.
If a CALL command is issued without the address parameter, it is assumed you wish to go back
on-line to a previously established call, having used the PAD recall facility to temporarily return to
the PAD> prompt.
