COMMUNICATIONS

Our communication team provides product realization services through hardware and software design, development and implementation.

With wide ranging expertise in telecommunications, we have executed projects using various proprietary systems and associated tools.

Our services are focused on the following areas:

   Wireless network
   Optical networks
   Data network
   Voice switching network

With wide ranging expertise in telecommunications, we have executed projects using various proprietary systems and associated tools.

1. Wireless network
We offer expertise in 2G, GPRS, PDC and 3G wireless product development. This ranges from protocol development, network design and re-engineering to porting, testing and network management.

2. Optical networks
We have extensive design experience with various types of network elements including access nodes and SONET/SDH and WDM transmission systems. We also have an understanding of SONET architectures and relevant Telcordia / ANSI and ITU standards.

Incorporating TMN standards, our services include:

   OAM & P
   Firmware development
   UI displays
   Incorporation of provisioning features (including setting and retrieving configuration data using TL1 and SNMP).
   Performance monitoring for SONET termination boards / SONET reliability
   Network Management for optical equipment / TL1 provisioning interface board / ASIC design for optical equipment.
   Verification and Validation for SONET / SDH equipment

3. Data network
Our expertise in data networking covers a diverse range of technologies including ATM / Frame Relay and TCP/IP.

Our experience in this area covers:

   ATM / Frame Relay / Embedded TCP/IP stacks (customization and migration services).
   Software for ATM PON optical subscriber units
   ATM LAN emulation software
   ICMP / RIP / SNMP/ SLIP / PPP enhancements for an embedded TCP/IP stack
   SNMP agents for IP forwarding
   OSPF, RSVP, MPLS and QoS applications
   Network Management for DSLAM equipment
   Hardware/Firmware development for high-speed Optical Routers, ATM Inverse multiplexers, Gigabit Ethernet switches, and token ring / Ethernet gateways
   Verification and Validation services for high end routers and next generation ATM switches

4. Voice switching network
Voice over Packet provides a commercially viable solution for unified messaging and CTI based applications. This requires breaking up the functionalities present in monolithic Centrex switches into a distributed network of specialized servers like media gateways and controllers. Our design and development experience in this area covers:

   Voice over Packet networks (VoIP)
   Development of H.323 Gateways
   H.323 - SIP interworking
   SS7 interfaces and Call Managers
   Media Gateway Controllers
   Basic call setup and telephony features for Trunking and Residential Gateways.
   Interfacing Gateways with various switches.
   Integration with call centers and customer care products
   Interworking signaling protocols like ISUP (and variants) to PRI, CAS
   Basic call setup and telephony features for Trunking and Residential Gateways.
   Board / ASIC design for Speech Codecs
   Network Management for PBXs
