1.0 PURPOSE

This document describes the electrical and mechanical interfaces of the A3LA-RM. Model A3LA-RM is a

satellite modem comprised of a 9523 L-band transceiver (LBT) with an extended input voltage range. The
A3LA-RM has an internal micro-controller programmed to monitor the modem‘s connectivity status to
prevent hardware lock-up. It is designed to transmit either AES 256-bit encrypted or unencrypted data via
the Iridium satellite network. Similar to a standard landline modem, the A3LA-RM can be controlled by any
DTE (data terminal equipment) capable of sending standard AT commands via an RS232 serial port. A DTE

can be a desktop computer, a laptop computer, a smart phone, or even a micro-controller. The A3LA-RM is
functionally compatible with models 9522B, A3LA-R and A3LA-RS. It is approximately 60% smaller in
volume and 50% lighter than the 9522B. Model A3LA-RM-MIL is an A3LA-RM that has been certified to MIL-
STD-810G standards and IP67 rating

Services supported include:

1.

Dial-Up Data Switch

2.

Direct Internet Connection (or NIPRNET Connection)

3.

Direct Internet Connection using Apollo Emulator (only for DoD EMSS Gateway)

4.

Short Message Service (SMS)

5.

6.

Router-Based Unrestricted Digital Internetworking Connectivity Solution (RUDICS)

7.

Voice when combined with the DPL audio handset

IMPORTANT: User should not disassemble the A3LA-RM for repair or services. The

warranty is voided if the A3LA-RM is disassembled. It should be returned to NAL Research
for any services.
