Non-Initializing Terminal Mode
(North America only)
Non-Initializing Terminal (NIT) mode is a new ISDN protocol feature
that enables the DIVA T/A to operate without SPIDs. You can use
NIT only if your ISDN provider supports it.
To configure the DIVA T/A for Non-Initializing Terminal mode,
deselect the SPID checkbox in the Windows Configuration Tool, or
specify Yes for the Non-Initializing parameter in the VT-100
Configuration Tool.
Note: Check with your ISDN service provider to determine if they
support Non-Initializing Terminal mode.
