*R

*R0

*R1

Control remote access security. With remote access security on and passwords set,
password entry determines whether the modem grants Level 0 or Level 1 access at the
start of a remote access session. With remote access security off, the modem does not
require passwords and grants Level 0 access.

Remote access is available only during a normal connection or during an MNP
reliable connection without data compression.
•
You must disable remote access security on the local modem, not during a remote
access session.
•
Set all passwords before you enable remote access security. Otherwise, an error
message appears.
