3Com 3C13866 4 x Ports E1/PRI Flexible Interface Card for Router 6040 / 6080

Product Description

The 3Com 3C13866 is a flexible interface card specifically developed for the 3Com Router 6040 and 6080 series. This card provides four E1/PRI ports, which are essential for establishing digital leased line connections. E1 is a standard for digital telecommunications transmission in Europe and many other parts of the world, operating at 2.048 Mbps. Primary Rate Interface (PRI) is a type of ISDN service that uses E1 or T1 lines to carry voice and data traffic. This interface card allows routers to connect directly to E1 circuits, which can be used for various purposes, including carrying multiple voice channels (e.g., 30 voice channels plus signaling for ISDN PRI) or high-speed data links. It is crucial for businesses that require dedicated, high-quality WAN connectivity for voice services, such as VoIP or traditional PBX integration, as well as for data transmission over leased lines. The 3C13866 card enhances the versatility of the 3Com routers by enabling them to interface with a wide range of telecommunications providers and WAN services that utilize E1 infrastructure. Its four ports offer significant capacity for connecting to multiple E1 circuits, supporting complex WAN configurations and providing redundancy for critical communication links. This makes it a valuable component for enterprise networks and service providers operating in regions where E1 is the prevalent digital transmission standard.
