Product Description
The 3Com 3C13788A is a specialized interface module designed to provide a single T1/ISDN-PRI (Primary Rate Interface) connection. This module is intended for integration into compatible 3Com networking hardware, enabling direct connectivity to T1 lines. T1 lines are a standard telecommunications service that provides digital transmission capabilities, commonly used for carrying voice and data traffic. The ISDN-PRI functionality allows this module to support multiple channels (typically 23 B-channels for voice/data and 1 D-channel for signaling) over a single T1 connection. This makes it suitable for connecting to Private Branch Exchanges (PBXs) for business phone systems, integrating with the Public Switched Telephone Network (PSTN) for external voice communication, or establishing high-capacity data links. As a multi-function module, the 3C13788A offers a dedicated and reliable way to manage voice and data services over a T1 circuit. It is a critical component for organizations that rely on T1 infrastructure for their communication needs, providing a bridge between their internal network and external telecommunications services. Its single-port design focuses on delivering this specific, high-capacity interface efficiently.
