EASY CONVERSION OF LEGACY DIAL-UP SOLUTIONS TO THE CELLULAR NETWORK

The new USR® Courier® Modemulator™ and Cellular M2M Gateway is a drop-in cellular replacement for legacy analog systems that require peer-to-peer connectivity†. Emulating a dial-up modem allows equipment to seamlessly connect over a cellular network instead of over the PSTN in legacy M2M applications. Existing legacy hardware and software systems remain untouched when used with the Modemulator — providing extended product life and simplified cellular deployments. Compatibility with both the PSTN and packet switched data networks provides network flexibility that allows an open ended transition plan and eliminates the need for a system overhaul — saving both time and money. By providing a 2-in-1 device, analog customers can transition select sites to cellular in the most efficient and cost-effective way while utilizing the network that is right for the situation. USR's Modemulator & Cellular Gateway provides reliable, secure connections for mission critical M2M applications.

USE CASES

Remote Management

The Challenge

In remote network management applications, Network Managers oversee network infrastructure equipment that is installed at many remote sites. For years, dial-up analog modems have been used to make contact over the PSTN to the remote sites to enable the remote management activities.

As PSTN service becomes less available and more expensive, an upgrade path to cellular remote management is needed. However, the operation of cellular modems and cellular networks are drastically different from the operation of analog modems and legacy telephone networks, making the transition difficult.

The Solution

USR® has developed a technology called “Modemulation” that can simplify the transition from dial-up out-of-band remote management to cellular. Using a Modemulator at the network operations center, a Network Manager can contact a remote Modemulator over the cellular data network by entering the same dial command that is used for dial-up modems. The two Modemulators replace two dial-up modems and operate as a seamless “drop-in replacement” for dial-up modems and the PSTN.

The Modemulator can also route a connection over the PSTN from a local dial-up modem to a dial-up modem at a remote site that hasn’t been upgraded yet. Both cellular and dial-up sites can be managed conveniently using one terminal and the same familiar dial command.

3520-msp-diagram-generic-lo.png

How It Works

The local Modemulator interfaces to a terminal’s serial port, just as a dial-up modem would. The Modemulator accepts commands and returns responses that mimic a dial-up modem. The remote Modemulator interfaces to the console port of the networking equipment (or port server), just as a dial-up modem would.

An Administrator assigns an arbitrary phone number to each remote Modemulator, and enters that phone number and the IP address and port number of each remote Modemulator into a phonebook in the local Modemulator. When a dial command (e.g. ATDT555-1234) is entered into the Modemulator from the terminal, it searches its phonebook for an associated IP address. If an entry is found, it will connect to the remote Modemulator, allowing the Operator to manage the remote networking equipment.

The connection is made to a GSM or CDMA 3G cellular data network, and the data routing is provided by a Mobile Virtual Network Operator (MVNO). A special service from the MVNO allows routing from one cellular device to another within their network, without crossing a firewall or traversing the public Internet. Such private data routing is extremely secure because 1) cellular data networks do not allow direct device-to-device communication, 2) the subscriber’s private sub-net is isolated from other devices on the MVNO network, and 3) routing from the public Internet is blocked by the MVNO firewall.

If an entry is not found in its phonebook, the Modemulator realizes that the phone number is addressing a dial-up site and automatically routes the dial command to an attached dial-up modem.

FAQs

What is a “Modemulator”?

USR’s exclusive “Modemulator” is an expansion card that when installed in a USR3510/USR803510 Cellular Gateway serves as a drop-in replacement of serial dial-up modems. The Modemulator emulates a dial-up modem, which extends the life of application software and hardware while providing the benefits of cellular connectivity.

The Modemulator is also unique in that it can maintain support of peer-to-peer dial-up connections as well as cellular connections.

Why can’t I use any cellular modem as a drop-in dial-up modem replacement?

Most cellular networks use a different type of technology that isn't compatible with dial-up analog systems. Our Whitepaper explains in detail the how's and why's but the high level answer is that most cellular data networks are packet based, rely on IP addresses, and are client/server whereas dial-up systems are peer-to-peer direct connection and rely on phone numbers which normally cannot communicate without additional hardware and/or software that could complicate how a solution works.

Learn more with the Cellular to Cellular Data Communications White Paper

Why Emulate an Analog Modem & the PSTN?

Legacy M2M application software that uses an analog modem for communications will send commands to the analog modem that set-up the modem and initiate or answer calls. Such software is generally not able to set-up and initiate or answer calls using a cellular data modem or gateway because cellular modem commands, cellular gateway GUI, and the cellular network are fundamentally different than the analog modem commands and phone network.

USR Modemulator technology allows a legacy M2M system to be conveniently converted to cellular without upgrading or replacing application software. The Modemulator accepts and responds to the most common analog modem commands, and sends result codes that mimic a PSTN connection to the application software, which enables drop-in compatibility with the legacy application software.

How much can I expect to save by replacing analog modems with Modemulators?

The cost of analog phone lines is on average $50 per month per line. Cellular services when pooled can provide even greater cost savings with small data packages and low data volumes. The cost savings increase as the volume goes up, whereas the dial-up monthly expenses are consistent but pricey.

Can I replace leased line analog modems with Modemulators?

With firmware release 1.0.02, leased line dial-up modems can be replaced and provide even greater cost savings per month.

Can I use the SIM from my phone for Modemulator?

Generally no. The SIM from your phone is not provisioned for peer-to-peer data connectivity, which Modemulators require in order to emulate the analog PSTN and dial-up modems. However, depending on how your SIM is provisioned, it may allow connectivity to the Internet, and Modemulator can use this type of connectivity when operating in single-ended mode to originate a connection to the IP address of a TCP/IP server.

How does the Modemulator work?

In Modemulator (modem + emulator) mode, the Modemulator presents to a User (or to legacy application software) a command-line interface (CLI) that mimics the AT commands and responses of analog modems, but connects to another Modemulator (or to an IP server) over a cellular data network instead of the public switched telephone network (PSTN). This allows the easy conversion of a legacy M2M system that was based on analog modems connecting over the PSTN to a more modern M2M system connecting over ubiquitous cellular data networks, without upgrading legacy application software that expects an analog modem, or without installing new middleware onto the application computers.

To facilitate the gradual conversion of legacy systems to cellular, the Modemulator can also initiate and answer connections over the PSTN to sites with analog modems by automatically diverting commands to an analog modem attached to its MODEM serial port. This provides the User a unified interface and protocol for connecting with both cellular and analog sites.
