Disconnecting NTO devices from IMS

You can disconnect the session between a network terminal option (NTO) device and IMS by issuing certain commands. NTO devices will also disconnect when IMS terminates or when VTAM® terminates.

The session between an NTO device and IMS terminates when any of the following occurs:

  • IMS terminates.
  • VTAM terminates.
  • The network operator enters a VARY INACT command.
  • You do one of the following at the NTO terminal:
    • Issue a /RCLSDST command.
    • Enter a logoff command.
    • Disconnect the phone connection for a switched device.
  • You enter the /CLSDST command from the IMS master terminal.
  • Data or transmission errors force termination of the session.
Restriction: You must not stop the NTO logical unit using the IMS /STOP command. The network operator must issue the VTAM VARY command (with ANS=ON for switched devices).
