Establishing Authentication
The Cisco ATA supports two levels of authentication, depending on the setting of the UseLoginID
parameter:
• If UseLoginID is set to 0, the user ID (UID0 or UID1) is used with a user-supplied password (PWD0
or PWD1) for authentication.
• If UseLoginID is set to 1, you must supply a login ID (LoginID0 or LoginID1) and a password
(PWD0 or PWD1) for authentication.
