SocketModem
Embedded Dial-up Modem
®
Universal Socket Benefits
• Interchangeable communications
devices
• Quick-to-market
• Global approvals
• Easy migration to future networks
The Multi-Tech SocketModem
®
embedded modem creates communication-ready devices by integrating data/fax
modem functionality into a single, universal socket design. The SocketModem embedded modem utilizes a space-
efficient (1" x 2.5"), design that allows OEMs to integrate a wide range of modem functions and speeds into any
product platform. The complete, ready-to-integrate modem dramatically reduces development time and costs for
system designers. The SocketModem embedded modem complies with telecom requirements globally and can be
shipped worldwide.

Highlights
Applications. With connect rates from 300 to 56,000 bits
per second (bps), the SocketModem embedded modem is
targeted at applications that periodically need to send or
receive data over a standard telephone line. It is ideal for:
• Appliances
• ATM terminals
• Credit card and check verification systems
• Data collection
• Gas pumps
• Industrial and medical remote monitoring systems
• Point-of-sale terminals
• Remote diagnostics
• Remote metering
• Security systems
• Television set-top boxes
• Ticketing machines
• Vending/gaming machines
Integration Reduces Space, Power and Cost. The SocketModem
embedded modem integrates the controller, data pump and
data access arrangement (DAA) in one communications
device. This integration requires low power, low real estate,
and provides an overall reduction in costs.
Reduces Development Time. The SocketModem embedded
modem can make your existing and next generation device,
machine, or system, communication-ready without requiring
significant hardware changes to its design. The SocketModem
embedded modem actually provides faster time-to-market
because it relieves the burden and expense of writing
modem controller code. The complete, ready-to-integrate
modem allows you to enhance your product while you focus
on developing its core features.
Real-time Data Transfer. By adding the SocketModem
embedded modem to any system application, you will
achieve real-time data transfers at the fastest analog modem
speeds. For data communications, the industry-standard
V.92 modem downloads at 56K speeds from a digital V.92
server and uploads at 48K bps. If needed, the SocketModem
embedded modem will negotiate slower speed connections
automatically. For fax applications, it supports industry-
standard V.34 (33.6K bps), V.17 (14.4K bps) or Group 3 (9600
bps) faxing using Class 1/1.0 or Class 2/2.0/2.1 commands. If
your application does not require fax capabilities, a lower-
cost module is available.
Industry-standard Modem Commands. The SocketModem
embedded modem provides industry-standard AT-style
commands for ease of integration into your existing software
applications. In addition, it also provides industry-standard
error correction and data compression to shorten transfer
time and ensure data is sent error-free.
SocketModem Pin-Out. The SocketModem embedded modem
interfaces easily with existing products through a standard
serial or parallel communication channel. The complete on-
board DAA interfaces with an RJ-11 jack for direct connection
to the public switched telephone network. The SocketModem
embedded modem provides audio circuit outputs for audio
call-progress monitoring, and LED driver outputs for visual
monitoring of Carrier Detect, Transmit Data, Receive Data
and DTR signals. The SocketModem embedded modem
is a Data Terminal Equipment (DTE) device with a serial
or parallel interface. The serial DTE channel is capable of
transfer speeds to 230.4K bps and can be interfaced directly
to a UART or microcontroller.
Universal Socket Connectivity. Multi-Tech's universal socket
flexible comm-port architecture provides analog dial-
up, ISDN, wireless, or Ethernet socket connectivity with
interchangeable communications devices. This allows you
to utilize one system design and populate it with your
communications device of choice. In addition, you are
assured a seamless migration to future technologies.
Advanced Set-up and Control Features. The SocketModem
embedded modem has several advanced features built into
the design. It supports remote configuration, which means
you can have central site setup and control of the remote
modem. In addition, the communications devices provide
three-number storage for automatic dialing capabilities and
non-volatile memory (NoVRAM) to store user profiles.
Global Compliance. The SocketModem embedded modem
has successfully completed international compliance
testing (homologation) for global approval. This means one
communications device can be specified per design without
having to integrate specific country approved devices for
each system used across the world.
Firmware Upgrades. The SocketModem embedded modem
also features flash memory to allow for firmware updates.
These upgrades allow the user to stay current with the latest
enhancements that Multi-Tech has to offer.
