Digital Switching System

Advanced, Reliable, Economical

General

CARIN-LX1 is the most powerful system for supporting your communications online applications. Extensively utilizing VLSI technology, it provides a variety of configurations and capacity options.

CARIN-LX1 architecture allows the system capacity growth with no additional configuration, administration or reprogramming.

CARIN-LX1 provides flexible expansion from its minimum (200 ports) configuration to its maximum capacity (45,568 ports) with no loss of existing hardware and through easy employment of the building block modules.

CARIN-LX1 with its distributed control structure, high degree of modularity and VLSI based switching network can perform both circuit and packet switching simultaneously.
