CHAPTER 2: Overview
2. Overview
2.1 Introduction
With the Modem Router Switch, you can switch inbound modem calls to any of
eight receiving modems (PCs, servers, etc.) that the caller selects. Designed
primarily for modem applications, you can also use it for voice, fax, or other analog
switching applications. The switch also enables you to switch devices on outbound
telephone lines. Or, you can simply reboot your PC using the optional power
adapter (40420).
The Modem Router Switch has two telco line connections and eight modem ports.
2.1.1 I NBOUND C ALLS
When used to route inbound calls, the caller selects the desired port when placing
the call. The Modem Router Switch’s two primary operating modes (Touch-tone
and Secure) enable the call routing. Select the desired operating mode via a rotary
switch (see Figure 2-2 and Table 2-2 on pages 12–16).
The Touch-tone mode provides a simple DTMF tone port selection method. The
caller simply enters a password and the desired port number. You can do this
manually from any touch-tone keypad or by appending the proper character
sequence to the “AT Commands” for dialup modem applications.
The Secure mode requires a matchbox-size Security Selection Key (part number
40419) with an eight-position rotary selector switch that connects to the caller’s
modem. The security device encrypts the handshake with the Modem Router
Switch and automatically switches the call to the selected port. Any call received
without the proper corresponding Security Key aborts within a half second. This
eliminates wrong numbers and nuisance calls. Calls by any of the “hacker” type
War Dialers are also not recognized as a modem.
2.1.2 O UTBOUND C ALLS
For outbound calls, the Modem Router Switch also acts as a telephone line switch.
Any of the “switched ports” may bid for the available telco line simply by going off-
hook. If the line is already in use by another inbound or outbound call, the
bidding modem receives no dial tone.

10
MODEM ROUTER SWITCH
2.1.3 S ECURITY K EY (P ART N UMBER 40419)
You can program the Security Key through the RJ-11 “Program Ports.”
NOTE
Each Security Key may be programmed differently, allowing only
various units to access selected ports.
Each Modem Router Switch transfers a unique factory system ID code and a user-
selected ID to the Security Key during programming. This prevents the Security
Key from being used on other systems. The Security Keys are shipped
programmed, to have all ports enabled, but you can change this programming.
In either touchtone or secure mode, the switch can abort unauthorized calls and
route them to the “Default Port” (Port #1). This allows you to share the Modem
Router Switch with other normal voice or data activity on the phone line.

3. Operation
3.1 Answering Inbound Calls
The Modem Router Switch answers calls via the following two steps:
1) When a ring signal is received, the switch answers the call, verifies security,
and determines which port is requested.
2) Next, the switch rings the selected port and sends a false ring back to the
caller. When the selected device answers, the call connects.
NOTE
The call will always be answered by the switch, even if the equipment on
the ports will not answer.
If the ports don’t answer, the call may disconnect after three rings. You may also
request a port that is busy on another line. This lets you know that the modem you
requested is not available. In this case, you will hear four busy signals and the
Modem Router Switch will disconnect.
3.2 Optional AC Power Control Unit
The device on the “selected port” does not need to be constantly powered on.
Install an optional AC power strip (part number 40420) at the terminal/modem.
The caller then controls the AC power strip that’s connected to the selected port
through ON/OFF/RESET touch-tone commands.
NOTE
Only the AC outlets on the power strip labeled “Control Ports” are
controlled by the Modem Router Switch. Use the other ports as standard
power-strip ports.
3.3 Programming
3.3.1 P ROGRAMMING THE M ODEM R OUTER S WITCH
Now that you have an understanding of the components and their functions, you
can program the unit. For example, to program the unit to recognize Touch-tone
input, simply turn the Program Mode Switch to position #2 and press the Enter key
until the Routing LED (#9) turns red. Then, turn the Program Mode Switch to
position #0. The Mode LED turns green to indicate the Run Mode.
