Originate Access Security; Answer Access Security - Paradyne COMSPHERE 3920Plus Technical Reference Manual

COMSPHERE 392xPlus Modems
The COMSPHERE 392xPlus modems use an outbound and inbound method of security known
respectively as Originate Access and Answer Access security. Both methods of security require
some type of password entry whether it be included as part of an AT command dial string or
entered directly from a remote user's DTE.

Originate Access Security

Originate Access lets you control who can originate a call from a local modem via the AT
command set. This is useful in LAN and modem pooling applications. With Originate Access
security, a local user's password is embedded in the AT dial command. If the password is valid, the
user can dial out using this modem.
The following example illustrates the format for an Originate Access password:
ATD%abc123%T9,8005551234
Originate Access Security is enabled or disabled by the Set Originate Security group.

Answer Access Security

The other method of security, which is the primary focus of this chapter, is Answer Access.
Answer Access allows the answering modem to restrict entry to the host DTE by ensuring that
originating (remote) modems and/or users have been granted proper security access. Access can be
granted by using one of three techniques: VF-side password entry, DTE-side password entry, or a
combination of both.
