Can The Modemulator Connect Simultaneously To Several Remote Sites; Can I Use The Modemulator To Connect To An Analog Site Over The Cellular Network; Can The Modemulator Be Connected To The Console Port Of A Cisco Router - US Robotics USR3520 User Manual

Modemulator User Guide
Also, since the Modemulator is sending and receiving digital data (not voice), the cellular service must be
a data plan (not a voice plan).
And in order to emulate the operation of the legacy PSTN, the cellular data plan must be provisioned for
peer-to-peer connectivity and static IP addressing. These provisioning features are available only from an
M2M cellular data plan (not from consumer cellular data plans).

Can the Modemulator connect simultaneously to several remote sites?

No, the Modemulator emulates the behavior of dial-up modems and the PSTN, which allows only point-to-
point connections from one endpoint to one other endpoint. A Modemulator must disconnect before a
connection to another site can be made.
Can I use the Modemulator to connect to an analog site over the cellular
network?
No. A dial-up modem sends and receives analog signals that can connect only to another analog modem.
Modern cellular networks don't contain analog modems and don't offer analog services. The voice services
that cell phones use are actually sending and receiving digital voice, not analog.
And also, cellular modem and gateways make data connections, not digital voice connections. The cellular
network's digital voice service is too low-fidelity to carry a dial-up modem's analog signal.

Communications whitepaper.

Can the Modemulator be connected to the console port of a Cisco router?

Yes, with the proper cable and adaptors, and with the proper settings, the Modemulator can connect to a
Cisco console port.
The Cisco console port is a serial port which can connect to the Modemulator's Terminal port. It may be
useful to consult Cisco's online Cabling Guide for Console and AUX Ports.
For example, if the Cisco console port is presented on an RJ45 connector, one way to make the connection
is as follows:
USR Modemulator
RJ45 to DB9F DB9M to DB9M
Cisco RJ45
DB9F Terminal
Console port
port
Standard Ethernet cable
(not rollover)
Gender changer
Cisco Terminal adaptor
(not null)
Cisco DB9F-to-RJ45
TERMINAL Adaptor
DB9M/DB9M
Gender Changer (Coupler)
