3Com 3C13718 5000 Series 2 x ISDN BRI (U) WAN Expansion Module

Product Description

The 3Com 3C13718 is a specialized WAN expansion module designed to enhance the connectivity options of the 3Com 5000 Series network switches. This module is equipped with two ISDN Basic Rate Interface (BRI) ports, specifically the 'U' interface type, which is commonly used for connecting directly to the telephone network. ISDN BRI provides two 64 kbps B-channels for data or voice and one 16 kbps D-channel for signaling, offering a digital alternative to traditional analog phone lines. This module is ideal for enabling digital voice and data communications in environments where ISDN connectivity is prevalent or required. It allows businesses, particularly small to medium-sized branch offices, to establish reliable connections for both voice calls and data transmission over the ISDN network. The inclusion of two BRI ports provides redundancy or the ability to manage multiple simultaneous connections, enhancing the utility and flexibility of the 5000 Series switch. Installation of the 3C13718 into a compatible 3Com 5000 Series switch is straightforward, allowing for quick deployment and expansion of WAN capabilities. It serves as a cost-effective solution for organizations needing to integrate with ISDN infrastructure for specific applications, such as remote access, small-scale video conferencing, or dedicated data links where ISDN is the mandated or preferred technology.
