Troubleshooting & Enhancements for TEM Card
Client: Major Telecoms Equipment Manufacturer
A leading Tier 2 client, specialising in the delivering converged multimedia solutions for the mobile, broadband and internet markets, engaged Asidua to provide High Availability enhancements on one of the subsystems within its DTG, namely the Transcoding Engine Module (TEM) card. Their flagship product, the Transcoding Media Gateway (DTG) provides seamless, low latency transport of voice and video traffic across networks.
Telephony Signalling Transport
Client: Major Telecoms Equipment Manufacturer
A major manufacturer of telecommunications and networking equipment engaged Asidua to implement support for Message Transfer Part 2 (MTP2) transport and optimisation on the Wintegra WinPath. MTP2 is a protocol in the SS7 protocol suite responsible for the reliable transmission of messages between signalling points. Asidua’s customised WinPath data plane software runs on the customer’s modular routing platform, performing tasks which are too processor-intensive to be performed on the host.
ISDN Line Card Development
Client: Major Telecoms Device Manufacturer
Asidua was tasked to develop the software for a DSLAM ISDN-BA Line Card which configures and manages 32 subscriber line pairs. The line card contained two Infineon DELIC devices providing a TDM traffic interface to each DELIC via IOM-2 bus providing ISDN on 32 subscriber pairs. Asidua is a strategic partner in the specification, design, implementation and validation of all real-time embedded software for a major telecom vendor’s access technology portfolio. This client is a key supplier in the access domain, providing solutions to link BT’s existing access network to the 21CN core IP-based network. Thanks to the client’s DSL Access Multiplexer (DSLAM), multiple services can be delivered simultaneously, from fast Internet access and video-on-demand, to voice telephony using VoIP.
Migrating Legacy ATM Networks to “triple-play” Ethernet
Client: Major Telecoms Device Manufacturer
Asidua’s client – a major telecoms device manufacturer – was involved in a project with a leading communications solutions provider to migrate the delivery of its broadband services to its next generation network. Part of this project involved the migration of existing ATM networks to Ethernet. Asidua’s involvement with this project concerned upgrading the software on existing linecards (from the old ATM network) to support the transport of “triple play” broadband Ethernet services to the next-generation network. The communications solutions provider required the Ethernet services to be part of its broadband offering.
E1 Line Card Development - Hardware Integration
Client: Major Telecoms Equipment Manufacturer
Asidua’s client – a major telecom device manufacturer – was involved in a project with a leading communications solutions provider to migrate the delivery of its legacy circuit-switched service offerings to its next-generation network. This network would allow for multiple services to be delivered simultaneously, from fast Internet access and video-on-demand, to voice and data telephony using VoIP. The communications solutions provider required for business E1 services to be part of their multi-service offering.
E1 line Card Subsystem - Software Development
Client: Major Telecom Device Manufacturer
Asidua’s client – a major telecom device manufacturer - was involved in a project with a leading communications solutions provider to migrate the delivery of its legacy circuit-switched service offerings to its next-generation network. This network would allow for multiple services to be delivered simultaneously, from fast Internet access and video-on-demand, to voice and data telephony using VoIP. The communications solutions provider required for business E1 services to be part of their multi-service offering.
E1 TDM/ATM Interworking in the Access Network
Client: Major Telecoms Equipment Manufacturer
A major telecoms equipment manufacturer re-engaged Asidua following successful development and deployment of an SNMP Agent on the manufacturer’s ATM Switch Fabric card. The remit was to design and develop the software for a new card that would offer E1 TDM/ATM interworking and traffic consolidation. The card would allow telecom network operators to make more efficient use of their core network bandwidth using a Circuit Emulation Service (CES) to transport E1 TDM traffic.
21st Century Access
Client: Fujitsu Telecommunications
The technical complexity of moving access networks into the 21st century and scope of developing a replacement network requires enormous investment of engineering resources in a coherent and effective manner. Fujitsu Telecommunications, a major telecoms equipment manufacturer, recognised Asidua as having this capability and expertise to deliver a cost effective and quality solution to meet aggressive time to market demands.
