What types of modules exist?

There are different types of modules. But which module is suitable for your situation? You have the choice of the following types:

  • WIC & HWIC Modules: A WAN Interface Card (WIC) module can allow network devices, such as a router, to connect and transmit data over a WAN. A WIC has a built-in CSU/DSU interface to connect to a digital circuit and provide error correction and line monitoring. There are also HWIC modules with higher speed than WIC modules.
  • Shared Port adapters (SPA): A Shared Port adapter is a type of port adapter that plugs into a subslot of a compatible SIP carrier card to provide network connectivity and increased density of interface ports.

We had old IT hardware purchased by Qualified Networks and our data carriers certified for data wiping. The service was fast and professional. Our old devices were sustainably processed, and the new hardware was delivered very quickly in top quality. A reliable and environmentally conscious choice – definitely recommended!

Still very happy with the service! Been a satisfied customer for years and recently had another great experience. We had our old IT hardware, including servers, switches and laptops, purchased. Everything was handled professionally and the data deletion was properly certified. The team was knowledgeable, fast and reliable. Definitely recommended for anyone looking for a safe and efficient solution for old hardware!
