Product Description
The 3Com 3C13722A is a specialized interface card designed to provide flexible Wide Area Network (WAN) connectivity. It features a single port that supports Fractional E1, allowing network administrators to provision and utilize portions of a full E1 (2.048 Mbps) digital circuit. This capability is crucial for organizations that require dedicated digital leased lines but do not need the full bandwidth of a standard E1, enabling them to optimize costs and resource allocation. This Smart Interface Card (SIC) is intended for integration into compatible 3Com networking platforms, serving as a key component for building robust WAN infrastructure. It facilitates the transmission of both voice and data traffic over these fractional E1 circuits, making it suitable for applications such as connecting branch offices, integrating PBXs with the PSTN, or providing dedicated data links where specific bandwidth is required. By offering Fractional E1 support, the 3C13722A provides a granular approach to WAN bandwidth management. It allows for the precise allocation of time slots within an E1 frame, enabling cost-effective deployment of digital leased line services. This card is essential for networks that need reliable and efficient digital connectivity for critical business communications.
