3Com 3C13769 5000 Series Expansion Module 2 x T1/CT1/ISDN

Description

The 3Com 3C13769 is an expansion module specifically designed for the 3Com 5000 Series of networking equipment. It serves to augment the connectivity capabilities of the host system by adding two ports that support T1, CT1 (Channelized T1), and ISDN PRI (Primary Rate Interface) signaling. This makes it a versatile component for integrating digital leased lines and ISDN services into an enterprise network. The inclusion of T1 and CT1 support allows for the connection to standard digital leased lines, which are commonly used for dedicated data transmission between locations. The CT1 capability further enhances flexibility by enabling the division of a T1 line into multiple lower-speed channels, such as 64 kbps increments, for more granular bandwidth allocation. The ISDN PRI support is crucial for connecting to the public switched telephone network (PSTN) for digital voice services, offering features like direct inward dialing (DID) and support for PBX systems. This expansion module is integral for businesses that require robust and scalable solutions for voice and data communications. It enables the deployment of services such as dedicated data links, integrated voice and data networks, and high-capacity connections to the PSTN. The 3C13769 is a key component for enhancing the functionality and reach of the 3Com 5000 Series platform, providing essential interfaces for modern digital telecommunications.
