Chapter 2Access Security Functions

In This Chapter

This chapter describes the following functions that implement password
security:
• Password verification
• Callback
• Callback dial restriction
• Configuration/phone number access restriction options.
Password Verification on Connection
With password verification, the 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.
To enable password verification, determine whether the modem or an
NMS will verify passwords. Follow the appropriate procedure below.
Callback Verification and Dial Restriction
Callback verification and restriction apply to incoming calls.
