Design and engineering of telecom equipment
Since 2004, Promwad has been helping customers to be on the cutting edge of telecommunication technologies, creating for them new networking devices and software within long-term R&D co-operation models.
We work with manufacturers of telecom equipment, integrators, and telecom operators to create commercially successful network solutions for faster and more accessible broadband Internet for end-users and businesses.
How we work
Our clients are companies with many years of experience in telecom, they do not just follow trends of the industry, but also set them through constant innovations and R&D process. To be in the avant-garde, to offer eco-friendly and convenient network devices – not only in terms of technology but also in terms of design – these are the goals set by our customers.
Many of our clients have their own R&D departments and experience with Chinese manufacturers. However, they choose Promwad to take their business to the next level, as they trust our experience in telecom electronics design and partnership with world-leading semiconductor vendors.
Telecom equipment engineering
LAN / WAN / WiFi routers
Our clients stay one step ahead of trends in the telecom market with the next-gen LAN / WAN / WiFi routers and other access point devices. Experienced since 2004, our team focuses on advanced telecom and rugged applications with high-speed interfaces, multi-layer PCB, proper thermal and signal integrity modelling.
We design Ethernet switching equipment which serves as an integral part of any intelligent network. Our telecom R&D unit has hands-on experience with network switch technology and switch SDK from leading chip vendors. Among the examples of Ethernet switching devices are:
- stackable & managed access switches
- carrier Ethernet switches/routers/gateways
- security appliances
- aggregation switches & routers
Telecom software development
We develop software for network equipment in compliance with the highest requirements for bandwidth and quality of service (QoS) performing the following tasks:
Customized telecom solutions
VoIP integration, and more
Our portfolio includes specialized distribution files for VoIP devices, embedded solutions for thin clients and mini-servers. We also developed a full software package for the second commercial plug computer in the world.
Promwad software engineers have developed system and user software for managed switches with Energy Efficient Ethernet and PoE support, home and industrial routers, hubs, and other network devices.
SDK: Microchip IStaX-APPL-2020.09.
Tested on a PCB135 debug board from Microchip on VSC7558. Q-in-Q operates on the Sparx-5 microprocessor family.
Description: Selective Q-in-Q determines the pairing of a given client VLAN (on the UNI side) and the sought S-VLAN identifier. The S-VLAN identifier is joined to the input unmodified C-VLAN, and the packet is forwarded across the ISP's double-tagged network. The S-VLAN ID is removed from the output, and the client VLAN ID is retained in the packet. Packets that do not match the specified client VLANs are discarded by default.
