Client: Ericsson, Inc.

Challenge: To design a complete solution for providing broadband services over a cable operator's HFC plant.

The high-level components comprising the project were:

• customer premises equipment (CPE)
• head-end equipment
• management software

The following major system functions were developed:

• Element management
  
• Software and configuration file management
  
• Network support services
  
• Subscriber/customer management

Mercury Carrier Class Network System (CCNS) product supported the overall operation of the Ericsson cable modem, cable modem termination system, and related products.

Solution: Our experienced development team designed:

• Multi-tier device provisioning server application for cable modem's
  Operation Support System. (the system included such features as cable
  modem user self-registration through Web interface, IP management, fraud detection, cable modem and telephony adapter management)
• Java based SNMP tools for cable modem management. (also designed SNMP/JDBC Java applications for working with HP OpenView web interface)
• DHCP server extensions to store IP-leases information in Oracle database and update dynamic DHCP server configuration from external JAVA application
• CORBA interfaces to control communication equipment interface with AT&T system network requirements

Result: The resulting solution was successfully presented at Western Cable Show (12/99) and enabled Ericsson to meet its delivery deadlines on time.

Client: 3COM, Inc.

Challenge: To design a network element manager to remotely manage 3COM Network Application Cards (NAC) and Network Interface Cards (NIC) through a Network Management Card (NMC) installed in an Enterprise Network Hub.

Solution: TLI's professionals created a system that provided ability to control any SNMP manageable device on a unified data communication platform and simultaneously supply a wide variety of data, voice and video applications. The same system was also designed to combine any applications within a single 3Com Hub chassis.

Project implementation included:

• Functional and detail specifications design & analysis for all object models.
• Object models and class diagram development for major components of TC1000 chassis, including High Density Modem (HDM/JHDM) and Network Management card.
• Interface development and modifications between JAVA Instant DB and CEM server.
• PYTHON scripts and XML files development to produce discovery process for HDM/JHDM card for dial-in and dial-out Internet access and implement SNMP commands for Card, Span, Modem and Template levels of systems.

Result: By developing the Common Element Manager, we enabled 3COM to expand its product line offerings and increase sales to the large-scale enterprise market.

Client: NASDAQ

Challenge: To integrate mainframe legacy database containing proprietary stock quotes messaging system with new Oracle database and modern messaging system.

Solution: TLI's development team implemented:

• Functional and detail specifications design & analysis for the messaging modules.
  
• COM/DCOM modules design for converting/translating legacy stock quote messaging system.
  
• Interface development and modifications between legacy stock quote system and the new messaging system.
• Proprietary C++ library development

Result: The resulting product ensures accurate and timely delivery of stock quotes and related financial information between legacy applications and modern NASDAQ systems.
