ATI Access
Access to the ATI is available through either the Terminal port or a Telnet session.
Access to the ATI through the Terminal port can be limited. Refer to
Terminal Port
Options
, Table A-5, to:
Enable Login Required.
Assign a Port Access Level of 1, 2, or 3.
The ATI can be accessed remotely through a Telnet Session via either the
Management port or the FDL. The DSU/CSU provides several methods for
limiting access to the ATI through a Telnet session.
Refer to
Telnet Session Options
, Table A-8, to:
— Enable Login Required.

To prevent the Management port and FDL from supporting a Telnet session:
— Set the Port Use option to None or Alarms. Refer to
Management Port
Options
, Table A-6.
— Disable the FDL. Refer to
Network Interface Options
, Table A-2.
Effective Access Level
The effective access level for the ATI is the more restrictive of the following two
access levels: the Port/Session access level and the Access level associated with
the Login ID. For example, if a login ID is created with an Access Level 1 and the
Terminal Port is set for a Port Access Level of 2, the effective access level to the
ATI is 2.
The effective access level determines what functions are accessible, as seen in
Table 7-1.
