PCI has especially designed CARIN-PCM8 to be compatible with its product ine of digital switching systems. CARIN-PCM consists of a concentrator module named PGC8 Card and a remote box named PGR Box. PGC8 can be installed in any subscriber line slot. The PGR Box will be installed at the customer premises.

» Advantages

CARIN-PCM8 has obvious advantages for current PCI’s customers in comparison to other solutions.

   • No need for any rack and space at MDF
   • No need for software configuration
   • No need for any power at MDF
   • No training is needed for MDF personnel
   • Use a pair of wire from switch to MDF
   • Rapid installation
   • Complete integration with existing O&M software
