be exercised:

z Y ou must remove and inst all cards in a static-free environment. W ear

an antistatic wrist strap that is plugged into the Kentrox equipment so
you are grounded at the same point as the equipment.

z Do not remove cards from their antistatic plastic bags until you are

ready to install them into the chassis.

z Immediately after you remove a card from the chassis, you must

insert it into its antistatic bag.

z When the cards are not in use, keep them in their antistatic plastic

bags.

z Do not ship or store cards near strong electrostatic, electromagnetic,

or radioactive fields.

Ground Caution

CAUTION: For Kentrox equipment to operate safely and correctly, there must be a

safety ground strap between the equipment ground bolts and the office
ground.

AI232 Version 9.6x User’s Guide

Product Description: Features

Features

AI232 is a high-performance asynchronous network interface card used in an
AIswitch. AI232 includes the following features:

Break Propagation

AI232 supports break handling from one end of a connection to another end
regardless of the protocols used for data tran sport. Refer to Chapter 7: Alias and Call

Routing Configuration for details about available types of break handling.

DCD/DSR/RTS/DTR Signal Lead Control

AI232 supports user selectable disconnect on DCD low, DCD high-to-low transition,
DSR low, and DSR high-to-low transition. Additionally, AI232 allows for user
selectable connection control of DTR/RTS.

Dynamic Port Configuration

AI232 allows for configuration changes on a per port basis without resetting the card.

IRB Connectivity

AI232 communicates with other cards in the same chassis over an internal repeater
bus. It cannot communicate over the backplane with line cards that do not use the
IRB.

LAN/WAN Connectivity

AI232 supports communications with other TCP/IP devices in a LAN/WAN
environment.

Modem Control

AI232 provides full modem control and is configurable for auto-answer or dial-modem
modes.

Performance Monitoring, Maintenance, Troubleshooting

Shell and winslc commands let users handle performance monitoring, maintenance,
and troubleshooting for AI232.

SNMP Manageability

AI232 supports configuration using SNMP as well as monitoring. SNMP traps are
generated by AI232 and are sent to all the management stations that exist in the trap
table.

1-2

Standalone Configuration

AI232 operates as a standalone card when it is installed in the AIswitch series 110
chassis. Standalone mode lets AI232 function without dependence on AI198 for
configuration and management. Refer to Appendix B: Standalone Mode and Switch

Mode for more details.

System Diagnostics

AI232 lets users view diagnostic data on existing connections and internal information
about serial links. For more information about viewing system diagnostics, refer to
sections:

z diag-conn on page 8-34
z diag-eth on page 8-36
z diag-info on page 8-44

AI232 Version 9.6x User’s Guide

Product Description: AI232 Hardware Components

AI232 Hardware Components

AI232 has four high-density connectors that provide 32 EIA-232-E asynchronous
ports that support speeds up to and including 115 Kilobits per second. All ports have
modem control for host or modem applications and can be used to connect user
terminals, personal computers, modems, and other high-speed asynchronous ports.
AI232 can also be used as a high-speed terminal server that handles asynchronous
to TCP/IP conversions. A distribution panel is required to serve as a physical int erface
for AI232.

CAUTION: AIswitch and its peripherals contain electrostatic sensitive components.

Exercise proper handling, shipping, and storage precautions.

Figure 1-8 Modem Multiplexer Application

The following events occur in Figure 1-8:

z The OSS sends a TCP/IP call to AI232.
z AI232 routes the TCP/IP call over a serial link to one of several available modems

in a modem pool. When a call comes in that requires a modem, one is selected
from the pool and dials out appropriately. For information on configuring the
modem pool and modem selection for incoming calls, refer to the Modem Mux
configuration menu.

Note: Round-robin dialing has been incorporated for ModMux links to balance

the demand placed on available modems by incoming calls. Rather than
always starting at the first available modem, the ModMux driver rotates
through all available modems so that the first available one is not always
the first to be dialed.

z The modem routes the call through the PSTN (packet switched telephone

network) to a remote modem.

z The remote modem sends the call to an NE.

Types of Menu Items

The following four types of menu items are available:

z Submenus
z Toggles
z Data
z Functions

Submenus

Submenus go to deeper levels in the menu hierarchy. They provide additional
configuration menus. Menu items that contain submenus have a plus sign (
their menu item number. In this example, menu item

+) next to

02 will display a submenu.

AI232 Version 9.6x User’s Guide

Using the AI198 Menu System: Navigating the Menu System

02+Configure as AI232 network interface card

Some submenus require a selection from a list and then re-display the previous menu
showing the selection. Other submenus have their own submenus that request
additional information. After saving the entries, the top-level menu re-appears.

Toggles

Toggles display two or more values that can be selected for a parameter. Toggles
have an asterisk (
toggles to the next selection.

*) next to their menu item number. Entering the menu item number

In this example, menu items

06*TCP Default Window Size (200, 512, 1024, 2048)-------------------------- 200
07*TCP Send Ahead-----------------------------------------------------------OFF

For

06*TCP Default Window Size, the user can toggle between values 200, 512, 1024, and

2048. For 07*TCP Send Ahead, the user can toggle between ON and OFF.

06 and 07 are toggles.

Data

Data menu items request text entries (such as destination names and card
descriptions) or numeric values (such as port numbers and IP addresses). To enter
information in a data menu item, enter the menu item number followed by a comma
(or a space) and the configuration information.

In this example, the menu item requires an IP address entry.

01 IP Address (0.0.0.0 - 255.255.255.254)------- ----------------000.000.000.000

To enter an IP address of 172.016.002.043, enter the following:

1,172.016.002.043

The menu re-appears with the entered IP address.

01 IP Address (0.0.0.0 - 255.255.255.254)------- ----------------172.016.002.043

To change configuration data that has been entered for a menu item, enter the menu
item number followed by a comma and the new data.

Tip: To change a typed entry, use BACKSPACE to back up to the desired position in

the text and retype the changes. However, once the user presses ENTER,
changes can be made only by selecting that menu item and re-entering the
data.

AI232 Local Menu System: Identifying AI232 Menu System Security Options

Identifying AI232 Menu System Security Options

AI232 has a variety of security options, including:

z Multilevel User Name and Password Security
z RADIUS Authentication
z TACACS+ Authentication
z PPP Authentication Protocols (PAP and CHAP)

Multilevel User Name and Password Security

Up to 10 configurable user account profiles can be assigned to an AI232 user. Five
system profiles are available for providing various levels of user access. For more
information about user profiles, refer to command profile on page 1-103.

RADIUS Authentication

RADIUS authentication verifies user login information against valid user information in
a database on a centralized RADIUS authentication server. A primary and secondary
RADIUS server are configurable to provide secure access for an entire AI232
network. AI232 RADIUS authentication is available for Telnet, asynchronous, and
synchronous ports. For more information on RADIUS authentication, refer to section
RADIUS Configuration on page 1-19.

TACACS+ Authentication

T ACACS+ authentication verifies user login information against the user’s permission
level on a TACACS+ server. Up to 9 TACACS+ servers are configurable to provide
secure access for an entire AI232 network. AI232 TACACS+ authentication is
available for Telnet, asynchronous, and FTP connections. For more information on
TACACS+ authentication and server configuration, refer to the following commands:

z aaa authen on page 8-7 z tacacs server on page 8-96
z aaa author on page 8-8 z tacacs server phase on page 8-98

AI232 Local Menu System: Identifying AI232 Menu System Security Options

PPP Authentication Protocols (PAP and CHAP)

All asynchronous and synchronous PPP links are configurable to use either PAP or
CHAP PPP authentication protocols. PAP establishes peer identity using a 2-way
handshake that is done only upon initial link establishment. CHAP performs a 3-way
handshake upon initial link establishment, then proceeds to verify the link with 3-way
handshakes at random intervals. CHAP also encrypts the user’s password over the
PPP link to provide added security.

Modem Multiplexer



The modem multiplexer gives users access to a modem pool. The modem pool is the
list of ModMux links with attached modems. When a call comes in that requires a
modem, one is selected from the pool and dials out appropriately. The phone number
to dial is configurable for incoming calls that need to be attached to modems.

Note: Round-robin dialing has been incorporated for ModMux links to minimize the

demand placed on individual modems. Rather than always starting at the first
available modem, the ModMux driver rotates through all available modems so
that the first available one is not always the first to be dialed.
