ATM Adaptation Layer
Asynchronous transfer mode (ATM) is a high-performance,
cell-oriented switching and multiplexing technology
that utilizes fixed-length packets to carry different
types of traffic. It can handle different kinds
of traffic (voice, video, data etc) in an integrated
way. Depending on type of application, ATM provides
different services like Constant Bit Rate, Variable
Bit Rate - Non Real Time, Variable Bit Rate -Real
Time, Available Bit Rate and Unspecified Bit Rate.
There is a need of a layer that can split the
use data into packets that are suitable for ATM
layer for transmission. Further a reverse action
is also necessary to receive data from multiple
sources.
The ATM Adaptation Layer precisely offers the
kind of desired functionality. It forms the layer
between an application and the ATM layer. The
AAL segments the user data into multiple small
packets, appends information necessary for reassembly
at the receiving end and presents it to the ATM
layer for further processing. At the receiving
end, this layer reassembles the data and presents
it to the application layer as a single block
of data.
There are various ATM service classes such as
CBR and VBR. These classes have associated bit
rates and connection modes. These are classified
into different application classes (A, B, C and
D). There are different ATM Adaptation Layers
associated with each application class. The AAL3/4
is associated with class C & D of network
traffic.
The software is being developed on VxWorks5.4
RTOS. The platform used for development is Tornado
2.0.

Porting of Linux 2.4.x on EST MDPPro Power
PC board
Client
UK based fixed wireless radio manufacturer
Project Duration
12 person months, off-shore
Technologies
Linux 2.4.x, Motorola 860T PowerPC,
gdb
This project involved porting of Linux kernel
version 2.4.12 to EST MDPPRO board. This first
involved writing a boot loader, which would be
able to load the Linux kernel and provide some
other facilities like booting over the Ethernet
using TFTP, BOOTP etc. The VxWorks boot loader
could not be used because it had no knowledge
about the Linux kernel. The boot loader chosen
was ppcboot and was successfully ported to offer
facilities like PCMCIA/Compact Flash boot, Flash
Programming and also to provide extended support
for booting Linux kernels.
A debugger was developed for debugging the kernel
.The hardware was built roughly based on the BDM
protocol, which is supported by the MPC860 family.
The Software interface to this was through the
GDB Stub. The stub BDM4GDB was ported to support
this hardware and can be successfully used to
single step the kernel with advanced features
like memory walk, setting breakpoints etc. Debuggers
like SingleStep, VisionClick etc could not be
used because they cannot handle virtual memory
translations and are not open source to support
the necessary changes to suit development cannot
be done. During this process a bug (the stub used
to change the value of SRR1 in its implementation)
was found in the Linux kernel and was reported
to the Linux community. The bug was accepted and
now stands fixed in the new version of Linux.
With the debugger working, the kernel could now
be debugged.
Along with the kernel device drivers for devices
like Ethernet, Fast Ethernet, HDLC, SMC, SCC ,I2C,
SPI, PCI, PCMCIA were also ported.

Calibration and Automated Test for a Fixed Wireless
Radio
Client
UK based radio manufacturer
Project Duration
10 person months, onsite
Technologies
VxWorks, Tornado, LabView
ODU transmit power is a function of amplifier
control voltage. In practice, the gain of an inexpensive
amplifier varies not only with control voltage,
but also with temperature and RF frequency. Therefore
it is necessary to measure power versus control
voltage characteristics for several temperatures
and all RF synthesizer channels. A similar exercise
needs to be carried out on the receive side as
well. It is therefore required to calibrate the
outdoor unit (ODU) of the radio to reduce the
dependencies on the temperature and frequency
variations. In addition to the above, various
tests need to be done on the ODU to ensure that
it meets the ETSI requirements.
The following figure gives an overview of all
the hardware components involved in the IDU as
well as the ODU.
Firmware Development
A socket server and parser was built into the
firmware to communicate with the GUI. The hardware
had the MPC860T PowerPC processor. VxWorks (Tornado
environment) was the RTOS used. Drivers were developed
for the following modules
IF Module (Tx, Rx Synthesizers)
Ref Module
RF Module
RF Synthesizer Module (SHF Synthesizer, Duplex
Synthesizer)
Automatic Level Control (ALC)
Once the calibration is complete, power, control
voltage pairs are stored in the EEPROM over various
frequencies and temperature. The firmware reads
the ambient temperature, interpolates the voltage
value for this temperature and sets the gain to
maintain the power level constant.
Automatic Gain Control (ALC)
Any radio receiver receives a power that is variable
due the atmospheric conditions and frequency dependence
of the circuitry inside. The receiver part is
designed to work faithfully for a received signal
of specific power range.
The consequences of extreme limits
in the received signal can be seen straightforward.
If the received signal strength is too high, then
it possibly damages the one or more amplifiers
in the series of amplifiers in the receiver path.
If the power is too low, the BER (Bit Error Rate)
increases and no information exchange will take
place.
The AGC software uses the AGC
values stored during calibration to keep the received
signal strength constant. As the name suggests,
this is a closed loop control system
GUI for Calibration and Test Setup
A user friendly GUI was developed for selection
of the tests to be performed. Additionally this
LabView based GUI provided graphs of Power Vs.
Control Voltage settings at various temperatures
and frequencies, for both transmit and receive
side calibration. Our team developed all the drivers
required for each of the instruments. A facility
to print a pass/fail report was provided for each
of the tests performed. The test engineer could
change/correct the hardware if a particular test
failed and run only that test again. The front-end
software is connected to various instruments through
GPIB, Ethernet or Serial (RS232) interfaces. It
communicates over these interfaces to set or get
the data.

Palm/Windows CE Command Line Interface
Client
US based fixed wireless radio manufacturer
Project Duration
3 person months, off-shore
Technologies
Palm OS, Windows CE, C++
One of the most powerful interfaces for configuration
of embedded systems is the command line interface,
or the CLI. Most embedded systems use the CLI
interface for configuration of box parameters
like IP addresses, hardware register addresses,
MAC addresses, etc.
In the classical case, the CLI
software running on the embedded system communicates
with a dumb terminal, where the user types previously
known, and syntactically accurate commands. These
commands are accepted by the CLI software running
the embedded system, and appropriate internal
commands are executed. These commands show the
values of certain parameters or set the values
of some parameters.
The problems with this approach are:
The user of the CLI must know the exact command
that needs to be typed. In a complex CLI program,
these commands can be either too long or too cryptic
to remember
The user needs to do a lot of
typing, which slows down his/her interaction with
the CLI program on the embedded system.
Any change in the spelling or
the structure of the CLI requires a re-learning
effort on the part of the user, who may have become
familiar with the earlier structure of operation.

SNMP Agent Auto Code Generator
Client
US based fixed wireless radio manufacturer
Project Duration
5 person months, off-shore
Technologies
SNMP, XML, Java, C++, UML
AutoSNMP is a Rapid Application Development (RAD)
tool for automating embedded SNMP agent development.
It enables OEMs to rapidly build monitoring and
control capabilities into ‘smart’
electronic products that can be managed remotely
via an Ethernet network or through the Internet.
This product helps in greatly reducing manufacturers’
development risks and speeding products’
time-to-market.”
The tool provides a user-friendly MIB editor interface
to create and edit ASN.1 compliant MIB files.
All MIB elements (MIB files, tables, table elements,
scalars and traps) are easily created by the IDE.
No direct editing of the ASN.1 MIB file is required.
The input from the MIB editor is converted to
an XML format file with a pre-defined Document
Type Definition (DTD). XML with its element, attribute
and namespace capability can cover the specification
requirements of many domain languages like C++,
C or Java. A separate XML file is created to define
the desired view for generating the CLI. The tool,
also allows a view & edit facility for the
XML files generated
The XML file is parsed by the tool to generate:
MIB database for the SNMP Agent and ASN.1 file
for the Manager. This includes support for basic
data types, tables, link tables and simple sub-typing.
C++ Access APIs for the database,
which include database operations such as getValue,
setValue, testValue, compare, print, get and set
functions for NV storage
Code to integrate with SNMP v1,
v2c or v3 agents
CLI code for user defined CLI
view. This includes provision for security feature,
command completion, detailed help.
The MIB and behavioral specifications
defined in the XML file are used during code generation
to create a central database within the embedded
application along with the SNMP agent for managing
the database. Public APIs are provided for setting
and retrieving data values. With this tool, a
complete SNMP agent can be up and running in minutes.
