emote password access to
serial communications
equipment is yours with the
Secure Rack Modem. It uses the
Public Standard Telephone
Network (PSTN) to transfer data
at modem speeds of 33.6 kbps.
Two models are available: one
for 115 VAC and one for 48 VDC.
The modem can store up to
100 individual passwords and
dialback numbers in non-volatile
memory. Designed for remote
sites, the modem always resets
itself to answer on the specified
number of rings. The modem is
also set to a fixed baud rate at the
modem port.
Securely access serial communications
equipment remotely over the PSTN.
Key Features
SECURERACKMODEM
No external AT commands are
required to configure the Secure
Rack Modem upon power-up, so
you can easily use it with
equipment that cannot send an
AT setup string.
Password and/or Dial-Back Entry
The user directory stores up to
100 user names with individual
password and optional dialback
number. When the modem
answers, it sends an Enter
Password prompt. If the caller
enters the correct password, the
modem opens the path to the
connected equipment. If the
directory password field contains
a dialback number, the modem
will hang up after receiving the
password, dial the number, and
open the connection path when
the called modem answers.
Access Tracking
An audit trail log tracks valid
and/or invalid password
connections, the time and date of
each connection and the duration
of the call. The modem stores a
snapshot of the last 100
connections. Only the system
administrator can view this
snapshot.
Local or Remote Configuration
You can configure the system
locally via a serial DB9 console
port on the modem. Alternately,
the system administrator can
configure the modem remotely.
This allows the administrator to
communicate to a secondary
serial device other than the
modem port, such as a reboot
switch.

• Remote dialup management, direct connection: The Secure Rack
Modem provides network administrators with a secure way of
dialing into a remote site and connecting directly to a network
element for remote management. The most common network
element is a router or UNIX
®
machine.
•
Remote dialup management, sharing devices: The rack modem can
communicate with a remote port sharing device; this allows the
administrators to use one phone line and one secure rack modem to
communicate with several network elements at the site. The most
common sharing devices are terminal servers such as Cisco 2611,
Lucent PortMaster, Xylan, or the Network Power Switch (SWI069A)
from Black Box.
