1. Introduction
The AFS-16-1 is a versatile switching system, designed for applications that require
routing of analog or digital signals between a common RJ45 jack and “A” and “B
RJ45 jacks. The AFS-16-1 is ideal for switching RS232, RS422/485, Ethernet/UTP or
telephone lines.
The system consists of a Card Rack, one Power Supply Module, one Control Module,
and up to 16 Circuit Modules. Each Circuit Module is capable of switching all 8 pins of
the Common RJ45 jack between Jack “A” or Jack “B”. Each card can be switched by
alarm, manually, or by command.
The AFS-16-1 includes an assortment of alarm features, which allow the unit to monitor
temperature, power interruptions, and invalid access attempts and then notify you
via Email, text message, Syslog message or SNMP trap when critical conditions are
detected. The AFS can also monitor device response to ping commands and then
switch A/B paths and provide notification when devices fail to respond.
Security and Co-Location Features:
Secure Shell (SSHv2) encryption and address-specific IP security masks help to prevent
unauthorized access to command and configuration functions.
The AFS-16-1 also provides four different levels of security for user accounts:
Administrator, SuperUser, User and ViewOnly. The Administrator level provides
complete access to all A/B switching functions, status displays and configuration
menus. The SuperUser level allows control of A/B switching, but does not allow access
to configuration functions. The User level allows access to only a select group of
Administrator-defined A/B circuits. The ViewOnly level allows you to check unit status,
but does not allow A/B switching or access to configuration menus.
The AFS-16-1 includes full Radius, LDAP and TACACS capability, DHCP and an invalid
access lockout feature. An Audit Log records all user access, login and logout times
and command actions, and an Alarm Log records user-defined alarm events.

1-2
Introduction
Environmental Monitoring and Management:
The AFS-16 can constantly monitor temperature levels, ping response and other factors.
If the AFS-16 detects that user defined thresholds for these values have been exceeded,
the unit can promptly notify you via email, text message, SNMP trap, or Syslog
message. The AFS-16 also records temperature readings to a convenient log file.
The AFS-16 can also notify you when excessive invalid access attempts are detected,
and can automatically lock ports when it determines that an unauthorized user may be
attempting to gain access by "hammering" the unit with random passwords.
WTI Management Utility
The AFS-16 includes the WTI Management Utility, which allows you to manage multiple
WTI units via a single menu. For more information on the Management Utility, please
refer to the User’s Guide that is included on the CDROM.
