The function of each connector is explained below.
Aux Port connector
You may administer the ASG Guard via a PC or terminal
connected to the front Aux connector.
Key switch
The key switch is used to turn the ASG Guard on and off. The
key can be removed in either the on or off position. The ASG
Guard cannot be turned on or off without a key.
LEDs
The LEDs display status messages. When the unit is operating
properly, the pulse LED will flash. The meaning of each LED is
explained in "LED Meanings," later in this chapter.

The function of each connector is explained below.
Aux Port connector
You may administer the ASG Guard Plus via a PC or terminal
connected to either the front- or back-panel Aux connector.
SIT
The SIT (System Initialization Tag) contains information, unique
to your ASG Guard Plus, that can be transferred to the ASG
Guard Plus by inserting the SIT connector.
Key switch
The key switch is used to turn the ASG Guard/ASG
Guard Plus on and off. The key can be removed in either
the on or off position. The ASG Guard Plus cannot be
turned on or off without a key.

2.5 ASG Guard/ASG Guard Plus Functional Overview
The ASG Guard/ASG Guard Plus provides the following basic functions:
•secure access to host device
•site connectivity
•alarm processing
•data buffering
Area Function
Secure Access As a front end to host devices, the ASG Guard/ASG Guard Plus
provides secured access. All users connecting to the ASG
Guard/ASG Guard Plus via network, modem or directly (AUX Port)
need to authenticate themselves before being passed through to a
host device or permitted to administer the ASG Guard/ASG Guard
Plus. Several authentication mechanisms are available in the unit.
The ASG Guard/ASG Guard Plus also provides a logical switching
function, which allows an authorized user to connect to any host
device listed in the user’s profile.
Site Connectivity Acts as a central point for connection to all equipment at the site.
Allows connection via a local terminal, dial-up modem, and
Ethernet. A dial-up modem can also be used for PPP connections
allowing remote access to network-connected devices.
Alarm Processing When attached to a maintenance port of a host device, the ASG
Guard/ASG Guard Plus can process alarm messages and other
ASCII based data streams. Alarm messages can be delivered via
modem or network connectivity. Using either PPP or network
connectivity, the ASG Guard/ASG Guard Plus can deliver SNMP
traps to network managers. The ASG Guard/ASG Guard Plus can
convert ASCII based alarms received on its host ports to standard
SNMP traps. Acting as a SNMP trap proxy agent, the ASG
Guard/ASG Guard Plus allows legacy equipment to be managed
and provides alarm-reporting functions.
Data Buffering The ASG Guard/ASG Guard Plus can buffer all data transmitted to
a host port by the attached device. Data is collected on a
RAMdisk. Error messages, CDR, traffic data and other information
can be subsequently delivered to a central location via dial-up or
network.

2.6 Security Management
The ASG Guard/ASG Guard Plus maintains a database of authorized users (that is, User
Database). Only users listed in the database and who successfully authenticate are allowed
access. Authentication methods include password-oriented methods (Password, Callback, and
Variable Callback) and token methods (ASG Key and Pager).
A Master level user assigns each user when the user’s profile is added to the database. The
access class determines which ports can be addressed and what information can be viewed or
modified within the ASG Guard/ASG Guard Plus.
2.6.1 Access Classes
Master - Master access permits the user to change all information in ASG Guard/ASG Guard
Plus. The Master user can therefore control when and how alarms are reported, add and delete
users from the user database, change user profiles, modify Action and Event tables, manage
data buffering and access all hosts. The Master level is the highest level of access.
Sysop 2 - A Sysop 2 level user can perform all functions listed above except modifying the user
database. The Sysop 2 level user can access all hosts ports and has access to the file
commands used to manage data buffering, can make changes in how ASG Guard/ASG Guard
Plus responds to alarms, and change the port configuration of the unit.
Sysop 1 - The Sysop 1 level user can view pending alarms, but cannot change it. Data buffering
commands are not available to the Sysop 1 user. The Sysop 1 user can access all hosts.
Host 1 to Host n - The host user only has access to a single host device. The host user cannot
access any of the ASG Guard/ASG Guard Plus functions. n= number of the host user. ASG
Guard can have up to four host users. ASG Guard Plus can have 16 or 28 host users. (To have
28 host users, the ASG Guard Plus must have an expansion board.)
2.6.2 User Database
Each ASG Guard/ASG Guard Plus maintains a User Database, as stated above. The database
consists of a Customer User Table and a Lucent User Table. The Customer User Table contains
users added by a Customer Master User (Cmaster). The Lucent User Table contains users
added by a Lucent Master User (Lmaster). Lucent users provide remote maintenance support for
the ASG Guard/ASG Guard Plus for warranty issues and under Service Agreements. See
Chapter 6 for commands and capabilities associated with the Customer User Table and Lucent
User Table.
