Description of Business
We design, develop and manufacture communications network equipment for enterprises and telecommunications operators worldwide. Our products enable both enterprises and network service providers to deliver high speed fiber access, while transporting voice, video and data to the end user. Our next-generation solutions are based upon our SLMS architecture. From its inception, this SLMS architecture was specifically designed for the delivery of multiple classes of subscriber services (such as voice, data and video distribution), rather than being based on a particular protocol or media. In other words, our SLMS products are built to support the migration from legacy circuit to packet technologies and from copper to fiber technologies. This flexibility and versatility allows our products to adapt to future technologies while allowing service providers to focus on the delivery of additional high bandwidth services.
