Password Verification on Connection
Password verification applies to incoming calls. With password
verification, the answering modem must receive a password from the
calling device, then validate it internally or send it to a Motorola
network-management system (NMS) for validation, in order to
complete the connection. If a password is invalid, the modem
disconnects.
Callback verification and restriction apply to incoming calls.
With callback verification, the answering modem that successfully
completes password verification with a calling modem hangs up, then
calls the modem back. The modems then pass data.
With callback dial restriction, the answering modem calls back only
stored Phonebook numbers, not numbers sent by a calling modem.
