OVERVIEW
Now multiple modems can share a single telephone line,
saving your company the expense of adding extra lines.
The BLACK BOX®Modem Router Switch enables you to
switch inbound modem calls from remote callers or dialback
modems between four or eight user-selected modems
attached to PCs, servers, and other DTEs in your office.
Although primarily designed for modems, it also works
with voice, fax, or other analog switching applications and
can even reboot your PCs using the optional AC Power Strip.
We offer the switch with one telco-line connection and
four or eight modem ports, or two telco-line connections
and eight modem ports.
For outbound calls, the device enables you to share a
single phone line among many devices. Any modem may bid
for the available telco line simply by going off-hook. If the
line is tied up by another inbound or outbound call, the
bidding modem receives no dial tone.
With inbound calls, callers enter a password and the
number of the port that they want to connect to. This can be
done manually using any touchtone phone or by appending
it to the dial string for dial modem applications.
For added security, you can purchase an optional
matchbook-sized Remote-User Security Key for each remote
user. That way, you can program the switch to allow only
remote keyholders access to all or a limited number of ports.
The key contains an eight-position rotary switch that
remote callers connect to their modems. It’s used to
determine which port will be accessed. When the remote
modem connects to the Modem Router Switch, the key
performs an encrypted handshake with the switch. It then
switches the call to the selected port.
In the secure mode, any inbound calls received without
the security key attached are aborted.
Each Modem Router Switch contains a unique ID code
and a user-selected ID, which are transferred to the key when
programming the switch. This prevents the key from being
used on other systems—or other systems’ keys from being
used on yours.
The Modem Router Switch also features an eight-position
rotary switch used to select between touchtone and secure
modes, and four-bit DIP switches used to program and secure
the device.
The 6-Outlet AC Power Strip features an enhanced AC
surge protection circuit. The strip allows a DTE to power on
when a remote user calls and selects the DTE’s port. It powers
off when the call is completed. The strip also recognizes
additional touchtone commands used to override the
automatic on/off feature.

The Modem Router Switch has several user controls, LEDs,
and connectors. 40416 has (5) RJ-11 ports: (4) are switched,
(1) provides connection to the telco line, and (2) are for
programming. 40417 has (11) RJ-11 ports: (8) are switched,
(1) connects to the telco line, and (2) are used for programming.
40418 has (12) RJ-11 ports: (8) are switched, (2) connect to
telco lines, and (2) are used for programming.
The Remote-User Security Key has (2) RJ-11 programming
ports. A push button switch enables you to enter various
commands. A four-position DIP switch appends your personal
security code to the unique system code that is factory-
programmed into your system. This is transferred to the
Security Key (if used). A programming-mode switch programs
the router switch as well as the Security Key (if used). LEDs
on the device correspond to the switch positions. In the run
mode, they display the connected port number and flash
when the router switch rings that port. The LEDs also inform
you of the routing method, the status of outbound calls,
and more.
The Modem Router Switch also has a connection for
an alarm buzzer, which will sound for 2 seconds when
an unauthorized call is attempted. In addition, an LED
on the Modem Router Switch flashes red until another call
is received.
